Installation of corrugations in a cast-iron pipe. Installing the corrugation on the toilet and the specifics of connecting plumbing with it

APARTMENT REPAIR

To install the toilet, we will use the following tools:

Screwdriver with nozzles. Hammer. Corrugation for a sewer pipe. Kern. For thread seal #8212; tape "fum" Drills (on concrete) Drill. Adjustable wrench.

To install the toilet, we need ready-made outlets, namely for water and sewerage, made in accordance with the apartment renovation plan. They are brought under a pre-purchased toilet, because. There are many types of connection available. Fastening can be external and internal. In our case, an internal mount is used. We install fasteners for marking. We apply markings on the tile at the installation site of the toilet bowl and on the inside we outline the drilling site for the toilet bowl fasteners. We fasten each connection to the floor with two bolts. Small chips are made with a core at the drilling sites so that the drill does not walk on the ceramic tile during drilling.

We make four holes using a concrete drill, into which we hammer dowels. We fasten the fastening bolts to the floor, but for further fine adjustment do not tighten them.

The corrugation consists of many internal membranes, which makes it possible to tightly fasten it in the technical hole in the wall and on the outlet pipe of the toilet bowl. The inner membranes prevent the corrugation from jumping off the toilet pipe, and the outer ones do not allow it to jump out of the plumbing hole.

With the help of corrugations, we can change the distance from the toilet bowl to the wall, as well as change the connection angle, which is very important.

Most toilets have external system water supply, but there are also those in which the water supply system is internal, hidden. We need a clamp nut. We put the nut on the tube in reverse order.

Cold water can be connected either with a flexible metal-plastic hose or with an existing copper pipe. Let's pay attention to the pipe coming out of the wall. It can be with internal or external thread. In this case, the thread is internal, so we will use an adapter. We install the adapter using tow.

Let's start installing the toilet.

Not all men can do plumbing work. However, installing a toilet with your own hands is within the power of everyone. For this, you do not need to have specific knowledge and skills. It is enough to show diligence and care.

First of all, disconnect the old toilet from the water. Then dismantle the fasteners with which it is attached to the floor. If these are bolts, then they just need to be unscrewed. If there cement base#8212; will have to fiddle around a bit. It does not matter if the base of the toilet bowl is damaged during dismantling, because now its place is in a landfill. Tilt the toilet backwards to drain the remaining water. Then disconnect it from the socket, which needs to be cut to a convenient size for the corrugation.

Do-it-yourself toilet installation

Measure everything carefully before installation.

When installing a new toilet, remember the “measure seven times” rule. Take all measurements very carefully, along with the tank. At this stage, it is better to tinker with the fitting longer than to redo this painstaking work. You can mark on the floor with chalk or another convenient “marker” the exact location for the new toilet.

When finished fitting, remove the cistern and mount the toilet to the floor. Toilet installation #8212; elementary matter. First you need to install it evenly and correctly and secure it with the fasteners that come with any toilet bowl.

As for the mounts themselves, they can be "external" or "internal". But anyway modern models toilet bowls are mounted either on bolts that are screwed into special dowel holes, or filled with sealant.

It is important to carefully read the instructions for each specific plumbing fixture, for example, installation wall hung toilet radically different method of attachment. And floor standing toilets different models fastened to the floor different ways.

It is very important to firmly fix the toilet. The old-fashioned method, when a wooden board was used as the basis for fasteners, we will not recommend. It is best to carefully cement the place under the base or mount the toilet directly on the tile.

The main thing is to tighten the fasteners as tightly as possible. The toilet should not stagger, it is not installed on the ship.

Connecting the toilet to the sewer

Sewer connection

At this stage, you will need corrugations and silicone sealant, which you can pre-buy in the market or in a store. Lubricate the toilet bowl with sealant and insert the corrugation into it.

Its other end must also be well lubricated and securely inserted into the drain hole. For such a connection, a corrugated pipe is very convenient. It is easy to adapt in the most problematic area of the bathroom. In this case, the tightness of the structure will be at the very high level.

By the way, the sealant does not need to be saved. Especially when you connect the corrugation to the sewer. Just make sure that its particles do not get inside the pipe itself.

Installing a cistern

We connect the toilet to the water supply

At the final stage, you need to install a drain tank. Depending on the model, it can be placed directly on the toilet or with a takeaway. Now most often there are cisterns that are mounted on the back shelf of the toilet bowl. Usually, four bolts are used for this purpose, which pass through the tank itself. The kit must have rubber gaskets to protect against leakage. Another gasket, which is located between the connection of the drain tank hole and the hole in the toilet bowl, must be well sealed during installation. Then there will be no leaks in your bathroom.

Last operation#8212; connecting the tank to the plumbing system. After that, you can say #171;test#187; your work.

Installing corrugations for the toilet: how to do everything correctly and safely?

With the introduction of new technologies, many things in our lives become easier, faster and more comfortable. A variety of household appliances, mobile devices and means of communication are so addictive that it is already hard to imagine how one could live without all this. Construction and communication technologies are also changing for the better. Just a couple of decades ago, simply replacing a toilet was a big problem. It was necessary to select new plumbing so that the outlet exactly coincided with the sewer outlet. Otherwise, large-scale fuss with the replacement of cast-iron pipes could not be avoided. But then plastic appeared, and massive bends were replaced by corrugations for the toilet bowl. And everything immediately became much easier. Now the replacement of sanitary ware does not require any special knowledge, or qualifications, or many hours of effort.

What is a toilet bowl and why is it needed?

A corrugation is just a plastic outlet, which differs from all the others in its flexibility. In addition, the length of the corrugation also varies - it can be stretched to the size you need (within reasonable limits, of course).

Such a branch connects the toilet outlet to the sewer pipe. And their relative position does not matter. The main thing is that the sewer is below the toilet drain, otherwise the water simply will not flow.

Quality corrugation #8212; system security guarantee

Of great importance is the choice of high-quality corrugations. As you know, the range of goods in hardware stores, as they say, for every taste and budget. In our case, you need to focus only on quality. The cost of a corrugation for connecting a toilet bowl is not so expensive as to significantly save money, and there can be many problems with a leaking outlet and indignant neighbors.

Unfortunately, domestically produced goods in this area are still significantly inferior to imported counterparts. So it is better to opt for the corrugation of European manufacturers. In addition, there are samples made only of plastic and reinforced with metal wire. The second is definitely better. They flow less often, do not sag and last longer.

When two items of plumbing stand side by side, it is more convenient to use one corrugation with a tap

In small bathrooms, where you need to install a large number of plumbing at the same time, and even place washing machine, sometimes there is simply not enough space on the sewer pipe for so many outlets. Then the corrugation for the toilet bowl with a tap is used. It will be a salvation if the sink or bath is located in close proximity to the toilet.

Note! When purchasing a corrugation, do not forget to also buy a can of plumbing sealant. Many manufacturers claim that you can do without it, but "God saves the safe."

“The work of the master is afraid” - proceed to the installation

It remains only to connect the outlet to the sewer system and the installation of the toilet corrugation will be completed. To do this, insert the edge with an external seal into the previously cleaned hole until it stops. It is absolutely not necessary to seal this joint, but this procedure cannot damage it either.

It is not necessary to seal the connection of the corrugation with the sewer pipe, but it is desirable

Several useful tips

When the toilet is far from the wall, it is important to correctly corrugate. It, of course, stretches, but everything has its limit, and if you stretch the pipe too much, its walls become thinner and their strength decreases greatly.

It is not necessary, before installing the corrugation on the toilet, to stretch it. Do this just before connecting to the sewer. Otherwise, you risk stretching the retraction too much.

Do not allow the corrugations to sag in the middle. This can lead to the accumulation of fecal masses at the bottom point and, as a result, to blockage. If the outlet of the toilet bowl and the sewer pipe are located high enough, you need to arrange a support for the corrugation from improvised materials.

Recently, it has been customary to close communications with protective screens or boxes with a door, and use the fenced-off space as storage for various small things. On the one hand, this is correct - it looks beautiful and the place is not empty. Just do not forget that the corrugation is not a cast-iron pipe. Under the weight of a can of paint, it can bend, and then burst. Conclusion: do not put heavy objects on the corrugated pipe, this is fraught with leakage.

How to put the corrugation on the toilet?

Why put a corrugation?

Toilet #8211; necessary element modern life. But for various reasons, it requires replacement of elements from time to time. At first glance, everything is simple: the old product must be removed, the new one #8211; put.

The corrugation is necessary in two cases: 1 #8211; when different systems issue, 2 #8211; when the toilet is mounted with an offset relative to the sewer socket.

But it often happens that they bought a good imported toilet, but it doesn’t work, because the apartment was built in Soviet times, and the sewerage system was installed under an oblique outlet. And the purchased product has a horizontal release type. How to be? Of course, if soon the apartment is planned overhaul with sewer replacement. then you can immediately bring the pipes to the desired type of outlet. And if such a repair is not thought of? Or it happens that they put tiles on the floor over old tiles, and the floor level has risen. We have to put the toilet higher, as a result, there is an axial displacement relative to the sewer socket.

The sequence of installation of a toilet with an oblique outlet.

How to connect it to the sewer network? Here corrugated pipe or corrugation #8211 comes to the rescue; the most popular element of plumbing, which replaced cuffs, pipes and couplings. Its popularity is due to significant advantages. Due to the elasticity, it is possible to install the equipment to be installed without taking into account the location of the sewer and the mutual correspondence of the drain pipe and the outlet. In addition, it does not allow an unpleasant odor to enter the room and prevents clogging of treatment communications. The corrugation greatly facilitates installation and, if necessary, can be easily replaced. For the toilet, you need a corrugated pipe with a diameter of 100 mm. Also, to install the corrugations on the toilet, you will need silicone or plumbing sealant.

When buying, you need to pay attention to the quality of the corrugated pipe, otherwise it will harden and crack at the outlet. Therefore, for the reliability of the connection, you should choose an elastic corrugation, but with a fairly hard rubber so that it serves for a long time. The installation of the toilet corrugation itself is simple. It looks like this: one of its ends (with o-rings) is inserted all the way into the sewer socket, the other (with internal membranes) is put on the toilet drain. However, even in such a simple matter there are little tricks.

Mounting Features

The corrugated pipe must be the same size as the toilet outlet, be sufficiently dense and without cracks.

Standard sizes of corrugations for a toilet bowl.

When putting on, you need to press hard on the corrugation, then the rubber seal will stretch, and it will tightly take its place. Despite the presence of outer rings and internal membranes that ensure the tightness of the connection, specialists insert a corrugated pipe after applying sealant to the outlet. Sealant is also applied from the sewer side, only on the inner walls of the socket, and not on the outside. After fixing the corrugation, it is not necessary to coat the joints with sealant! To check the tightness, you can (after the sealant hardens!) Pour 1-2 buckets of water into the toilet bowl. If the joints are dry #8211; everything is done well, there will be no puddles. When installing the corrugation on a new toilet bowl, you first need to put the drain pipe on the outlet of the toilet bowl, then, moving it to the sewer at a minimum distance, insert the second end.

The closer the toilet moves, the less the corrugation will stretch. Then, during operation, it will not sag and, as a result, will last longer than stretched and sagging from water. Of course, corrugation has its drawbacks. The most important of them #8211; thin walls that are easily damaged. And in the case when the toilet is far from the sewer socket, sagging and accumulation of water is possible. Then deposits will be visible in the place of sagging, which does not look very aesthetically pleasing.

Over time, chemicals for cleaning the toilet that get into the sagging place will corrode the material, then the corrugation will leak. When replacing an old vent pipe with a new one, it is not necessary to dismantle the toilet bowl; it is enough to remove the damaged pipe and clean the sewer socket and outlet from the remnants of the old sealant, scraping with a sharp knife. When replacing an old connection with a corrugation, a thorough cleaning of the toilet bowl drain and sewer socket is required. To do this, the remains of cement must be cut down with a chisel and wiped with a dry cloth so that there is no dust, mucus and residues of drains. The bell inside must

This type of plumbing work corrugation replacement, or elastic adapter, on the toilet, can be done without problems do it yourself.

Removal and installation process pretty simple, you just need to know procedure, competently conduct preparatory work And follow instructions on the use of aids.

In what cases is it necessary to replace the corrugation

Replacement is carried out for different reasons:

Changed the position of the toilet, the drain turned out to be on the side or higher relative to the entrance to sewer pipe (can't keep the pipes aligned). This happens in the process bathroom reconstruction implying a displacement of plumbing or a change in floor level.
Set plumbing fixture with outlet, not corresponding to the entrance to the sewer. Imported toilet bowls of the new sample fitted with direct drain, and existing communications adapted for oblique.

Old adapter leaked. It can leak like at the point of contact with the pipe or toilet outlet, and at the site of a rupture or crack. The problem is due aging and wear parts during operation.

IN rare cases the adapter is installed for a while while repairs are in progress in the bathroom: toilet bowl shifted from permanent place , but they continue to use.

Tools needed to replace the part yourself

For installation work should prepare:

additional fasteners, excluding sagging corrugations (for short And little stretched compounds not needed);
plumbing sealant- silicone sealant - for lubrication of mating surfaces;
knife or a similar tool for cleaning pipes from dirt;
rag.

To install corrugations no special equipment required, so you only have to buy a sealant, the rest can be found in the house.

Is it possible to change the element without removing the toilet?

The elastic adapter has minimum(at the highest compression ratio) and ultimate(at the lowest degree of stretching) length. These dimensions determine the possibility of installing the element in each case. The position of the toilet should be considered relative to the sewer intake.

If the corrugation is maximally compressed, then dismantle it without changing the position of the toilet will not work. The end, put on the toilet, comes on the branch pipe on average by 5-6 cm. This means that the stretching element must be compressed by at least the same amount. Accordingly, if it is fully contracted, it is impossible to remove it from the pipe.

How to remove the elastic adapter

When dismantling, observe certain course of action:

Disconnect the corrugation from a plumbing fixture.
Lift her up up, to drain the rest of the drain into the sewer.
Disconnect adapter from the entrance to the sewer pipe.

The easiest way is to remove the corrugation, if it is stretched. If the toilet is too close to the sewer pipe and the corrugation is compressed as much as possible, you will need remove plumbing fixtures and a little bit move her.

Important! Before dismantling the old corrugation, you should empty the sump: turn off the tap and drain the remaining water from it. The adapter is first disconnected from the toilet so that it is possible empty it of residual sewage.

Do-it-yourself preparation for installation without removing the toilet

Life time corrugations and no problems in the process of further operation of the plumbing fixture depend on how carefully the installation was carried out before the installation itself. preparatory work.

Pre-installation preparation includes some activities:

Held thorough cleaning internal and external surfaces mating with the corrugation of the elements - exhaust outlet toilet and inlet bell sewer pipe.
After dismantling the failed parts remain particles of old sealant, lime and grease deposits, other pollution accumulated over a long period of time.
After cleaning, all surfaces must be rubbed dry.
According to the instructions for use of the sealant, it may be necessary to degrease the socket and toilet bowl drain permitted means.

Attention! The remaining particles of grease and dirt can cause leaks due to insufficient contact of the sealant with the nozzle and, as a result, loose fit of mating surfaces.

The process of installing a new corrugation for the toilet

If preparatory stage was held fully And without breaking the technology, installation of a new corrugation will not cause problems.

Reference. When stretching the corrugation, you need to carefully monitor that its end did not jump out of the sewer pipe.

Sequencing:

The joint of the corrugation with the socket of the sewer smear with silicone.
Insert first end elastic adapter into the bell.
Install plumbing into place if its position has changed before.
put on second end corrugations for outlet neck toilet.
sagging corrugation tie up with pre-prepared fasteners.
Until the sealant is completely dry elements cannot be moved..

Important! It is allowed to stretch the corrugation only during installation, so as to return it to its original position incredibly problematic.

How to choose and install the corrugation on the toilet, as well as the pros and cons, characteristics and types of corrugations.

Cast iron pipes for connecting the toilet bowl and the sewerage system have always been the only and rational choice, without which not a single house and bathroom was left. but modern technologies they do not always stand still, and something new and unique comes to the old and ordinary.

The use of corrugations for the toilet

The toilet corrugation is a modern innovation that has come to replace old and rusty cast iron pipes. Increasingly, many professionals and ordinary residents opt for comfortable plastic and abandon traditional views on plumbing.

The cuff is a removable fixing element of the plumbing system, necessary for connecting the toilet bowl to the sewer system. Visually, it resembles a wide and relatively large branch pipe, which has corrugated walls and is made of modern classic thermoplastic.

What are the advantages

Cast iron has always been distinguished by its roughness and roughness. Sewer systems quickly became overgrown with dirt, and the need for pipe cleaning appeared very often. All this was replaced by the decision to use a new connection scheme, which was a light installation work, as well as the use of high-quality and durable material, which has many unique advantages.

New plastic solution initially had many controversial moments, but over time, the corrugations found their recognition and respect. Thanks to all this, new distinctive qualities have appeared that are not characteristic of any other result:

Easy and comfortable installation

Due to the ease of installation and the possibilities of plastic, absolutely anyone can handle the procedure, even the most distant from plumbing and without any specific skills. You can save on plumbing installation services, as well as do it just as efficiently and professionally, without worrying about the quality of the work of an outsider.

Ability to move and move

Corrugation is the only possible solution in case of moving or moving the toilet. With any other options, it is impossible to do this - you will have to completely dismantle the connection system and redo flooring.

Temporary toilet

From the past, another advantage also follows - this is the possibility of using a temporary toilet bowl. In a house where repairs have not yet ended, or some installation work is underway, it is recommended to install a temporary toilet. Thanks to the correct design and the capabilities of the rubber cuff, you can change the position as you need to conduct finishing works. In addition, the corrugation will be able to help you out in unforeseen situations when the outlet of the toilet bowl and the sewer system do not match.

Minuses

Like everything rational and artificial, there are also production disadvantages that are formed due to the improvement of the system:

A conventional soft cuff is not very strong and is easily subject to external damage. All this creates additional difficulties during installation and more attention to care for the mount.
The corrugation for the toilet bowl can be mounted and operated only in open space, without installation into the wall, as is used with other installation options.
With a large angle of rotation and sagging of the material, it has a tendency to frequent clogging and damage.
Due to the high demand for the product, there are a large number of fakes and replicas that entrepreneurs sell under the guise of the original product.

Characteristics of the sewer corrugation

The spillway structure is a durable, accordion-shaped, stretchable material that does not change properties even when heated and stretched. The corrugated tube has a sleeve with a rubber cuff, inside it there is a rubber seal, through which the sewer is connected to different types plum - oblique and horizontal.

Standard sizes are from 21.2 cm to 50 cm. The end of the tube with a convex hole and a cross section of 11 cm, is connected to a system of sizes 7.5 cm and 13.4 on the outer surface.

Types of corrugations for the toilet

To connect the toilet corrugation to the sewerage system, its different types can be used. Their variety comes not only with their typical softness, but also with very hard properties, which is a more reliable and durable solution. However, light corrugation is a more popular and common option, since its installation is much faster and does not require much effort.

To date, entrepreneurs offer toilet pipes of two types - ordinary unreinforced and reinforced. When choosing a reinforced use, fastening occurs due to a wire of small diameter, which is necessary to strengthen the walls of sewer pipes. This variety is considered more an expensive option, but the service time becomes much longer, and the characteristics of reliability and strength increase.

Also, the corrugations for mounting the toilet bowl can be divided into long and short. The chosen solution depends, first of all, on the distance of the toilet bowl from the sewer socket and the size of the toilet room. I usually recommend using medium-sized pipes, since short ones are stretched during installation and create the possibility of damage, and long ones create frequent blockages. The folded length is 21.2 cm, and if you try to stretch it, it will be all 32 cm. The compressed corrugation will already be 28.5 cm in size, and when stretched it will be 0.5 m.

Connectors also differ in the directed angle of the socket. There is a straight and curved view, regardless of the chosen angle - 45 or all 90 degrees.

Corrugation installation

To ensure proper installation and operation, you will have to prepare the following tools:

Perforator and drill with impact functions;
Roulette or meter;
Silicone sealant;
Corrugated tube with the required dimensions for installation;
Fum tape for sealing joints or tow;
Water supply hose;
Toilet bowl with the selected design;
Adjustable wrenches and heads for connecting water supply to the tank.

After preparing the tools and the necessary equipment, you can proceed with the installation and connection of the general sewer system.

The first step in the installation will be the correct location of the toilet, fixed on the floor surface. After cleaning the outlet and the socket pipe, you need to monitor it inside- it should be perfectly clean and straight. The remains of cement must be knocked down with a chisel or a special nozzle on a perforator.

The installation of the pipe itself is very accessible and simple: the rubber seal must be pulled onto the outlet, applying a little force and tightening the connecting assembly.
To avoid leaks, the joints should be treated with silicone sealant. It is necessary to apply in a circle, after which you need to fix the cuff and try not to move it until it is completely dry.

After waiting for the sealant to dry completely, it will be possible to proceed with fixing the toilet bowl in the chosen place. To fix the connecting element and the socket, it is also necessary to use silicone sealant, which will protect against possible leaks and serve as protection against the penetration of unpleasant odors into the room, which is very important for hygiene and comfortable use at home.

Replacing the old corrugation

It happens that due to damage or some other reasons, the connection becomes unusable and needs to be replaced. Due to the advantages of plastic, it will not even require dismantling, which is always characteristic of other methods of fixing the toilet system. Therefore, the replacement will take place very calmly and easily: all you need is a bucket and some rags.

First of all, the flow of water into the drain is blocked, then the connection fastening tube is disconnected, intended for entry cold water. Cistern freed from water and disconnected, after which the corrugated pipe is compressed and removed from the device, removing it from the socket. A new, already prepared pipe is inserted back, compressed and pulled onto the outlet. This should also be done with a stretched corrugation, otherwise nothing will work.

There is also an alternative replacement: first of all, disconnect main part, which is fixed on the toilet, after which it is dismantled and removed from the mounts. This happens due to the compressed position of the old corrugation, the removal of which can significantly complicate the entire process of replacement and installation.

The distance separating the toilet and sewer drain, it is necessary to reduce to the desired size, but this will not always be possible due to the small size of the room. In this case, unnecessarily stretched and long form it is necessary to strengthen with special selections holding the structure.

You should also not start and pay less attention to the corrugation when it begins to noticeably sag and stretch. In this case, it is necessary to immediately try to install the collections in order to avoid the possible dismantling of the old system. Supports also serve as a good help in dealing with blockages. Due to the correct angles of the cuff, there will be less blockages in the areas.

Another recommendation would be to eliminate the need to pour various chemical solutions and elements into the sewer. The household chemical industry is very aggressive, which can burn through or damage the rubber tie. With such a likelihood of consequences, you will not notice it immediately, since the corrosion will occur slowly and without external signs. However, a lot also depends on the formulas that you will merge: therefore, first of all, think in advance whether this can be done.

In the process of using the toilet, you will also notice that your corrugated pipe was not installed correctly. This will be talked about by water that stagnates inside the pipe and does not leave. To solve this issue, you will have to change the angles of the plastic corrugation and change its technical voltage.

Is it worth installing a corrugation

With proper installation and following all these recommendations, you will get a comfortable and unique connection that will be strong, strong and with the ability to move the toilet due to tension. And also the design will protect you from harmful and unpleasant odors from the sewer, which is one of the important points for a comfortable and cozy stay.

Corrugated pipe will be a real discovery in the world of plumbing technology, and will often save you in difficult situations associated with incorrect installation of old low-quality equipment. Moreover, because of its simplicity, you will be able to install the sewer system yourself, without having high skills and equipment, without relying on strangers, who often do their job poorly.

Review

Vitaly Sumy
I connected the corrugation to the toilet with a horizontal outlet using silicone sealant, stuck it into the cast-iron sewer socket with the help of an adapter and crimped it with a cuff that there was no smell from the sewer.

Sometimes only with the help of corrugations you can set the toilet in the desired position. When using standard rigid pipes, this is not always possible in the position in which the owner wants. The article will discuss in detail all the issues related to the use of plastic corrugations to dismantle the old or install a new pipe.

Features and purpose

Non-pressure corrugation (cuff) for the toilet, made of plastic, makes repairs in the toilet much easier. Previously, in order to connect the toilet structure to the sewerage system, they used cast iron pipes, which were distinguished by the severity and difficulty of installation. At present, it is much easier and more convenient to use for these purposes. plastic products. And in the conditions of many apartments, when every square centimeter counts, such a toilet corrugation is the only possible way out in order to install a urinal.

Corrugation is called a transitional element of the plumbing system, which is designed to connect the toilet pipe to the sewer pipe. This is a wide tube with corrugated walls made of thermal plastic. Its edge is a connecting cuff, thanks to which it is easier to join the pipe and the toilet outlet. The length of the corrugation is on average 25-30 cm, the cuff has a diameter of 13.4 cm on the outside, 7.5 cm on the inside (from the side of the toilet bowl). The end that is connected to the sewer pipe has a diameter of 11 cm.

The peculiarity of the toilet plastic corrugation is that there is a layer inside it that significantly increases its specifications. This is especially noticeable if you choose the products of the world's leading manufacturers, such as SML or Duker.

It is much more convenient and more profitable to install a corrugation on the toilet than a cast-iron pipe. Firstly, plastic is lightweight, costs less, and has a much longer service life.

It is easy to clean, you can do it yourself. Before installing the corrugation, no preliminary chasing is required.

Corrugation is not always used. In most cases, it is preferable to take a plastic pipe, it is much stronger.

Corrugation for a toilet bowl is used in some cases.

In a situation where the toilet bowl is axially displaced relative to the sewer socket. This can happen when, due to the tiling of the floor, its level rises, or when the owner decides to move the toilet, setting it to another place. In each such case, there will not be an exact docking of the toilet outlet and the sewer socket, that is, it will be necessary to use a special corrugated drain. If the toilet is replaced and a new one is installed in another place, the corrugation should be no shorter than 50 cm. If you do not use plastic, you will have to move the sewer pipe. If, at the end of the repair, the floor in the bathroom rises (and, accordingly, the toilet bowl rises), the replacement of the corrugations is not required.
Another situation is when the release itself is atypical. The toilet bowl is designed in such a way that the type of existing sewage system does not match the outlet. For example, sometimes it is required to put modern plumbing in an old-plan apartment. In it, the release is usually direct, and in outdated toilet models it is oblique.

Therefore, in the case when the equipment has a horizontal or vertical outlet, in order to connect it, you will need to use a corrugated pipe that can be bent to the desired angle.

Advantages and disadvantages

The advantages of plastic corrugations are many, and they are quite significant:

Ease of installation - a person without special knowledge can easily cope with the replacement of the pipe.
Budget - perhaps the main advantage along with ease of installation.
The only available option in case of moving or shifting the toilet.
In the event of a mismatch between the outlet on the toilet and the sewer socket, only plastic can be installed.
Suitable for a temporary toilet installed before the end of the repair.

Along with a large number of advantages, there are also disadvantages.

The fragility of the structure due to the small thickness of the pipe walls. If you drop something with sharp edges into the toilet, such as a piece of ceramic tile or glass, the corrugated pipe may be damaged and will have to be replaced.
If the corrugation is placed at the wrong angle or given the wrong bend, it can easily become clogged.
If the corrugated pipe is too long, it may sag under the weight of the contents.
The corrugation cannot be placed in the wall, only outside.
According to many users, the design has an unattractive and bulky appearance.

Types and sizes

Toilet corrugations may have such parameters.

Elasticity. Depending on it, they are soft and hard. The latter have higher strength and wear resistance. Soft corrugation can be installed on the toilet bowl of any configuration and with any type of outlet (vertical, oblique or horizontal). The more flexible the pipe, the easier it is to install.
Reinforcement. With it, plastic pipes are strengthened. For this, steel wire is used. Reinforced reinforcement lasts longer, but also costs much more.
Corrugated pipes also differ in length. On average, the range varies from 0.2 to 0.5 m. When purchasing fittings, you need to take into account the distance from the toilet to the place where the corrugation cuts into the pipe. It is better to always buy a slightly longer channel, about 5 cm more than required. This makes it easier to avoid leaks.

The corrugation diameter can be 50, 100, 200 mm. Before buying, you need to measure the diameter of the toilet hole, and, based on the figure obtained, purchase a pipe with the appropriate cross section. You can buy it at any building and finishing materials store.

A cuff is a piece of plumbing that is responsible for ensuring a tight connection between the toilet bowl and the sewer outlet. For every floor-standing toilet, it is necessary. Therefore, when purchasing plumbing, you should also buy a cuff in the kit.

The models presented in stores are different in many ways: material from which they are made, diameter, shape. The standard cuff diameter is 110 mm, but there may be other options. It is necessary to find out what type of outlet the toilet is equipped with, and what diameter it has, because it is on it that the cuff will be attached with the second end.

If the dimensions do not match, then it is necessary to purchase a simple cone model (in case the connection is direct), or combined with different output sizes (if the connection is offset).

If we classify cuffs, we can distinguish the following varieties:

straight smooth;
corner smooth;
conical;
eccentric;
corrugated.

There are also combined models: they are straight and smooth at one end, and corrugated at the other.

The fan corrugation is suitable for connecting toilet bowls with a horizontal or oblique outlet. It is installed in a 90 mm pipe (without cuff) or in a pipe with a cut of 110 m.

The cuff eccentric consists of two cylindrical surfaces connected together, but shifted relative to each other along the longitudinal axes. The standard diameter of the outlet seamless pipe is 72 mm.

According to the material from which they are made, the cuffs are divided into rubber and plastic. If the toilet model is modern, and the pipes are made of plastic, then polymer types are used. And for a joint with a cast-iron pipe, traditional dense rubber is suitable.

Be sure to take into account the shape of the outlet on the toilet. She may be:

vertical;
horizontal;
oblique.

Mandatory detail is a clutch. Models for plastic pipes are produced in limited quantities - only five types:

Pipe / pipe - products with smooth walls are fixed relative to each other by threads. Used for rigid plastic pipes, put on in turn at both ends.
Box/pipe – the tube contains a cable on one side and a compression clamp on the other.
Fitting with detachable connection.
The transparent pipe is suitable for soft corrugated pipe joints, strengthened by winding.

If you do not want to be disturbed by unpleasant odors, you can equip the toilet with a check valve. It can be installed not only in the toilet, but also in other plumbing elements that have access to the sewer.

The non-return valve protects each of the plumbing items from blockages, and eliminates odors, preventing them from spreading throughout the living space. This is true both for residents on the upper floors and on the lower ones.

How to choose?

Each product can be attributed to its type, guided by a combination of such parameters as:

length and diameter;
reinforcement;
elasticity.

You can choose the right product based on the desired parameters, as well as guided by the requirements for quality and strength.

It is advisable to buy a certified product, and also carefully study the markings on it before purchasing. There is no need to be tempted to buy a suspiciously cheap product, because, as you know, “the miser pays twice”, and it is likely that, having installed a penny corrugation, you will soon have to go to the store for a new one.

Dismantling of the old

To independently replace the corrugation on the toilet, you need to dismantle old pipe. This is a stepwise procedure that requires a certain sequence of actions.

To do it right with your own hands, you need to prepare a few buckets and unnecessary rags. First you need to turn off the water supply in the drain. Then you need to unscrew the tube that passes the water. After the water is drained from the tank, and then you need to remove the tank.

The dismantling process begins with the toilet. If it has been installed and operated for a long time, then most likely it is very firmly fixed in the cement. It is impossible to pull it out without damage. In this case, you need to hit the neck of the toilet with a hammer. From vibration, the impact on the cement base will increase, so the dismantling process will go easier.

In no case should you hit a pipe, especially a cast-iron one, as there is a risk of a crack or even its complete destruction. A crack in the corrugation cannot be repaired, and to install a new one, you will have to completely replace the pipe. This will incur additional costs of money and time.

When the neck is broken, you can dismantle the structure. First you need to swing it. If it doesn’t work out, you can try to knock down the cement base with a hammer and chisel. Often after this, the toilet cracks or breaks into pieces, they need to be disassembled. To prevent the toilet from flooding with water, you should cover the structure with rags.

After the toilet is dismantled, you need to knock off all the fragments and cement residues from it. As soon as its lower cut becomes even, you need to clean the socket and remove pieces of the toilet bowl from it. As soon as the channel is cleared, it must be plugged with a plug, otherwise bad smell spread throughout the house. After that, you can change the corrugated pipe.

How to install?

In order to change the corrugation, you will need the following tools:

hammer;
sledgehammer;
roulette;
glue "liquid nails";
fum tape;
keys;
hose to drain water.

It is very easy to do this. First you need to try on the pipe, for this the corrugation is applied to the place where it is planned to be connected. It will immediately be seen whether the neck of the toilet bowl, the sewer pipe and the corrugation itself are joined. Here you can also determine whether the length of the corrugated pipe is suitable.

If necessary, the corrugation is cut and marked. The points where the dowels will be should be marked with a marker. The base for the toilet also needs to be marked. A tank and a drain pipe are installed on the toilet. Using a perforator, you need to make holes for the dowels, after which the installation of a new corrugated pipe begins.

First, it is wiped with a dry cloth, then the sealant is applied to the gasket. After that, the pipe is inserted into the sewer hole. On the other hand, the pipe also needs to be treated with a sealant, after which the treated channel should be put on the toilet in the neck area. Noticed cracks and crevices must be sealed with the same sealant or liquid nails glue.

In the place reserved for the base of the toilet, you need to put a rubber gasket, after which it is necessary to apply silicone sealant to its circumference. Now you can put the toilet and fix it.

As soon as the glue "grabbed", you need to check the quality of the structure. To do this, flush the toilet and check if it is flowing from under it.

In addition to this method, you can heat the corrugated pipe. It is exposed to high temperatures until its end becomes soft. Then you need to immediately put on the corrugation on the outlet of the toilet. Next, the sewer socket is joined to the corrugation with the second end and a sealant is applied. The connection is now complete.

You can connect a direct outlet toilet to a sewer with an oblique socket using a plastic corner. Modern stores offer a wide range of products from this material. To prevent leakage of water from under the toilet, you need to use, in addition to the corner, a rubber seal.

See below for a master class on installing corrugations.

When purchasing, experts recommend taking into account the length of the corrugation. This is especially important for those bathrooms or toilet rooms in which the toilet moves away from the wall quite far. The corrugated pipe can be pulled out, but this action has certain limitations. And the more you stretch it, the thinner its walls will become, which has an extremely negative effect on its strength.

Before mounting on the toilet, it is undesirable to pull out the fittings. Only when docking with a sewer can it be stretched. If you do not follow this advice, the structure may sag, and this is fraught with the formation of a blockage in the system.

You can shorten the corrugation after measuring the desired length, but even then you should not cut it exactly to this distance. You need to leave a small margin of length.

When installing a corrugated pipe, it is important that the channel is bent, without preventing the water from draining freely. It is impossible to pinch the pipe, otherwise damage is possible, and in the future it will begin to leak.

It should not be forgotten that the corrugation is a fragile product and is not designed for excessive load. Nothing should put pressure on it from above or to the side.

The pipe is leaking

If a malfunction is found in the plumbing, this becomes the source of many problems. Untimely elimination of the breakdown can lead to both spilling sewage throughout the apartment and flooding the neighbors from below with water. Given that the odor emitted by the contents of a current toilet bowl is incredibly persistent and absorbs into furniture, walls, floors and ceilings, it is necessary to deal with a leak as quickly as possible.

Often the reason that the toilet is flowing can be a corrugated pipe, which is either installed incorrectly. It may also be initially of poor quality.

The corrugation looks like an accordion connecting the outlet of the toilet bowl with the hole in the sewer. To make sure that it is the corrugated pipe that is flowing, you need to drain all the water from the toilet and see where the leak has formed.

If confirmation is received, then the pipe must either be repaired or replaced. Before proceeding with the repair, you should find the place of the leak.

There may be two options:

the pipe is broken or cracked;
a leak has formed at the junction with the sewer or outlet of the toilet bowl.

Repair the corrugation in this way:

The crack must be dried (you can use a hair dryer), and then sealed with a rubber patch. Glue should only be waterproof.
Saturate a piece of clean rag with epoxy and wrap it around the hole. The repair site must first be degreased.
Soak the bandage with a cement mixture, then put the resulting structure on the pipe.
Cover the bandage with sanitary silicone and wrap it around the toilet drain.

It is important to note that all these methods can eliminate leaky docking only temporarily. After all, it is impossible to repair the corrugation and make it waterproof again. It is best to purchase a new pipe and rearrange it.

Why does a leak occur?

Especially often this happens when purchasing cheap equipment. A corrugation of dubious quality does not fit snugly enough to the pipe (its inner surface), and unwanted folds form on it. The appearance of a leak in this case is a matter of time.

Also, in some low-quality types of corrugated pipes, the skirt on the cuff is not straight, but cone-shaped. It shouldn't be. More expensive models, especially those made by leading companies in the market, have better quality and durability.

For quality repair it is advisable to seek help from specialists. At the same time, you should not leave plumbers unattended, it is better to follow what they are doing.

As for the materials, it is better to purchase them yourself, since very often called specialists try to save on corrugation, and this will inevitably lead to new leaks.

A blockage has formed

Such an unpleasant thing as a blockage in the sewer is known to the vast majority of homeowners. This is especially true for apartments where old pipes are installed, and sewer system used incorrectly. The appearance of blockages is due to the ingress of hair, dirt, grease, as well as undissolved detergents- shampoos, lotions, balms, soaps and others.

First, it is better to try to clean the toilet using a plunger. It is necessary to install it as tightly as possible to the drain and press it several times. This method is effective if the blockage is small and the particles in it are small.

If everything is not so simple, and the size of the cork is large enough, and it is covered with a layer of fat, then the plunger is useless. You can use chemical for drain cleaning. There are quite a lot of such funds in the respective stores. Their composition, as a rule, includes acids and alkalis, which dissolve blockages in the pipe.

Such a tool is simply poured into the pipe. To dissolve the cork, you need to wait at least 4-5 hours. After that, pour into the pipe hot water. It is best to do this at night, as it is at this time that the plumbing is least used, and the product will have enough time to clear the blockage.

You can use a mixture of soda and vinegar (for 1 pack you need to take 1 bottle). The effect of such a mixture will be similar chemical agent. After using both ready-made and self-made solutions, you must also apply a plunger.

All of these methods are good for removing fresh blockages. In the case of the formation of fossils in old pipes, they are unlikely to help. Then a metal cable may come in handy. It is placed in a pipe and rotated, gradually moving deeper. This can help with oil or hair blockages, but if spoiled pickles have been drained into the toilet, for example, or a sanitary pad has been thrown away, the cable is also powerless.

If you can’t get rid of the blockage, it’s better to ask for the help of professionals. You need to call the housing authority and leave a request. There are also paid services, which tend to respond more quickly and have all the necessary tools to fix problems. In difficult cases, blockages are cleared using special hydropneumoimpulsive equipment.

Corrugation - a pipe that is used as air ducts. The products of evaporation or combustion pass through it. It is installed between the equipment. Thanks to the corrugations, clean air always remains in the room, as ventilation occurs when connected to a kitchen hood. As for the appearance, it can be rectangular or round. The first of these is usually operated in manufacturing plants. Another model can be found in residential premises. Possible composition: plastic, galvanized or stainless steel, textiles are the least common. Installing corrugated hoods is a sure way to keep your kitchen fresh.

Varieties

What are the diameters of the corrugations for the hood

There are to take the most popular corrugations, then the value is 100 mm, 125 mm and 150 mm (for a kitchen hood). In industrial ones, it can also reach 200 mm, 250 mm, 300 mm. The choice depends directly on the power of the device. The diameter of the hood itself should be taken into account, respectively, they must match. If you want a large diameter, then you should look for an adapter at the same time to dock with the neck. The dimensions of the corrugations for the hood have several classic parameters. You can always find the minimum value in the instructions for the kitchen hood. The most commonly used are 100 mm and 120 mm. If you still couldn’t find the size, then use a larger one, this is especially good for the kitchen: the noise will decrease due to the low flow rate. With a reduced diameter, air will be pushed through, experiencing difficulties.

Installation

How to install corrugation on the hood in the kitchen yourself and why? In order for the air to be updated regardless of whether the hood is turned on or not, it is worth attaching the corrugation through the grill to the vent. Because in the hole there is a compartment for the air duct and for the removal of air. When installing, it is also necessary to take into account the technical characteristics - the size and length of the pipe, otherwise all the work done will be inappropriate. Remember the quality and reliability of the material you choose. In addition, it is better when everything is done in the same style, for the interior. It should be understood that the cost does not guarantee the proper execution of the installation, so study the collation. It also says how to install an exhaust duct in the kitchen.

How to choose the size

It is necessary to measure the entire length with a tape measure. And take into account the route along which the duct will pass. For example, its possible path lies through the closet, along the walls or along the ceiling. After calculations, it is worth adding another 10 to 15 percent to the total length. This important point before connecting the corrugation to the hood.

IMPORTANT! Specify the size of the corrugation in a stretched form. It is worth taking the length with a margin. Ideally, it is 3 meters, but even if it turns out to be a completely extra length, then it will not hurt.

In the opposite situation, with a shortage of material, you can attach the missing piece with adhesive tape, but this option reduce airflow. This should be done only in extreme cases. With the smallest number of angles, but with a larger degree, the hood is able to work much more smoothly.

How to fix the corrugation on the hood

In order to somehow connect the corrugation with the hood, you will need:

corrugated pipe
self-tapping screws
hose clamps or soft wire
ventilation grate or adapter
silicone sealant
adapters, there was no corrugation of a suitable size

How to attach the corrugation to the hood, after all the tools are ready:

Before work, clean the ventilation in the apartment
First, stretch the corrugation along its length, check the constituent elements. Avoid kinks, then the air draft will remain good.
Lubricate the neck of the hood with sealant
Put on the corrugation and secure with a clamp, if it is not there, then wrap it with wire.
It is necessary to lay this way to the end of the ventilation hole
Fix the ventilation grate with self-tapping screws
Then put on the corrugation with sealant
Fasten the work with a clamp
Check the exhaust system by connecting the hood to the mains. This is done as follows: turn on the hood at maximum power, now take a sheet of paper and bring it from below to the grate. A sign of proper mounting is the retention of the sheet - which means that air is sucked in. Everything, the problem of how to put the corrugation on the hood is solved.

REFERENCE! Do not wipe the outer surface, this will save you from extraneous unwanted odors.

You need to know that a vent hole is required. You can not close the mine completely.

If you do not want the corrugation to be on public display, then there is the possibility of hiding it. How to insert the corrugation into the hood inside so that it is invisible? This is easy to do with the help of wall cabinet doors, a decorative box, or other elements. To disguise it, you need to choose a color to match the furniture. To give harmony, try to arrange everything based on the style of the kitchen. Another option is to install overlays. It can be formed along the contour of the cabinet, thereby ensuring the secrecy of ventilation. It will not be difficult to lay inside kitchen sets. However, this will lose a lot of the necessary space, as well as add holes that will need to be cut.

If you don’t want to figure out how the corrugation is attached to the hood, then you can simply order a professional installation. Especially if the kitchen was made together with a custom-made hood. Then, the installation of the corrugation for the hood may not go according to the standard scheme.

Why you need to install corrugations on the hood

The use of corrugated pipes is good because they have many advantages. For example, most can afford to install them, and installation, as it turned out, is quite simple. In addition, they have a wide range of types and sizes and low weight in a compressed state. Hardy at high temperatures, thereby do not undergo combustion. Can be installed both indoors and outdoors outdoors, indicating functionality. They are placed in different planes, used in different parts of the systems. It is only worth taking care of once, as the freshness in the room is guaranteed for a long time.
