The corrugation for the toilet bowl is smooth. Corrugation for the toilet bowl - choose and install

Plastic non-pressure corrugation for the toilet greatly simplifies the repair of the bathroom. A few years ago, heavy cast iron pipes were used to connect equipment to the sewer. However, today plastic fittings have almost completely replaced the usual overall products.

Advantages and purpose of plastic corrugation

Plastic products have several advantages. Firstly, they are easy to install - anyone can handle the procedure for replacing a pipe. Secondly, corrugation is considered one of the only options in cases of transfer of the toilet bowl or its displacement. Thirdly, plastic pipe helps when repair work the apartment is not finished yet. In addition, the pipe will help out in cases where the outlet holes of the toilet bowl and the sewer socket do not match.

A modern plastic pipe often plays the role of the only option for installing the toilet in a certain position. This applies to those cases when the living space in the apartment is very limited, and the structure can only be installed in one position.

In addition, the pipe is used when new. This applies to cases where the old toilet was installed in one place, but after the repair, this part of the toilet becomes occupied by furniture or a washbasin. In order not to dislodge all sewer pipe, you can use corrugation. In this case, it is best to use long pipes of 50 cm or more.

How to choose a pipe - we share secrets with beginners

The plastic corrugation for the toilet bowl has one great dignity. Both non-pressure and pressure pipes have an inner layer that significantly enhances their specifications. This is clearly seen in the examples of world leaders in the production of corrugated pipes - SML, Duker and Pam-Global.

Installing corrugations on the toilet provides more advantages than installing a cast iron product. It weighs much less than a heavy metal channel, the price of plastic products is much lower, and the service life is many times higher. It is very easy to clean it yourself, and before you install the corrugation on the toilet, you do not need to emboss and use fittings. In addition, if, as a result of repairs in the toilet, the floor height changes and the toilet rises, the corrugation will not need to be changed to a shorter or longer one.

Do not forget that the plastic product cannot be mounted inside the wall, as it will not withstand the load. For this purpose, only cast-iron fittings can cope.

Before you buy a product, remember that each corrugation for the toilet has certain dimensions. Besides, plastic fittings subject to certain classification. Which type a product belongs to depends on parameters such as:

  • elasticity;
  • reinforcement;
  • length;
  • diameter.

According to the first parameter, pipes are hard and soft. The first type is characterized by high strength and wear resistance, so it can be placed in toilets on industrial enterprises and in large commercial buildings. Soft reinforcement has better elasticity, which makes it easier to install.

Reinforcement is the reinforcement of plastic reinforcement with special steel wire. The period of operation of reinforced corrugations is many times longer, but the price is, accordingly, much higher.

The armature also differs in length. On sale you can find products with a length of 20 to 50 cm. When buying a product, consider the distance from the place where the corrugation is cut to the toilet. We advise you to buy fittings with a small margin to prevent leakage.

Another important parameter is the dimensions of the reinforcement. Pipes can have a diameter of 5, 10 or 20 cm. This characteristic must be taken into account so as not to buy reinforcement with a cross section larger than necessary. Before going to the store, measure the diameter of the hole in the toilet, and with the resulting size, go to the store.

Do not forget that each product must have its own quality certificate. Be sure to study the marking of fittings and bypass stores with confiscated goods.

Disabling and removing a worn channel

Replacing the corrugation on the toilet requires dismantling old pipe. To do this, be sure to stock up on a few buckets and old rags. First, turn off the water supply to the drain tank. Then unscrew the tube through which water enters. Drain the water from the tank and remove the tank itself.

After that, start dismantling the old corrugation. At the same time, remember that if the toilet has been in operation enough long time, then, most likely, it is firmly cemented into the floor. In this case, dismantling the toilet without damage will be almost impossible. In such a situation, use a hammer to hit the neck of the toilet with a hard blow as if you want to split it. The vibration from the impact will act on the cement base, making removal much easier.

In no case do not strike the pipe itself, especially if it is made of cast iron. As a result, the material may crack or shatter into small fragments. It will not be possible to repair the crack, and to install a new corrugation, you will have to completely change the pipe into the sewer. This will cause difficulties and financial costs.

Once you destroy the neck, you can begin to dismantle the structure. First, try to swing it in different directions. If this does not work, take a hammer and chisel and try to knock down the cement base. Often, as a result of this, the toilet cracks or collapses. In order not to flood the room, collect water with rags.

As soon as you remove the toilet bowl, knock off the remaining cement from it until its bottom is perfectly flat. After that, clean the socket, removing fragments of the toilet neck from it. As soon as you clean the channel, put a plug on it to prevent the smell from spreading throughout the apartment.

Installation of a plastic pipe - performance features

Before changing the worn corrugation on the toilet, we recommend that you study the method in which the fixation is performed using dowels. This method is the simplest and is perfect for beginners. For work you will need:

  • hammer or sledgehammer;
  • tape measure or ruler;
  • liquid Nails;
  • FUM tape or tow;
  • drain hose cold water from the toilet;
  • set of keys.

The work is done according to a very simple algorithm. First, try on the purchased pipe. To do this, attach the corrugation to the place where it will be attached. So you can see if the diameters of the toilet neck, sewer pipe and corrugation itself match. In addition, in this way you will check whether the new channel is suitable in length.

If necessary, cut the corrugation and start marking. With a marker, mark the points for the dowels and outline the base for the toilet. Install the tank and drain pipe on the toilet. Drill holes with a puncher at the points marked earlier. Start installing the new corrugation. To do this, wipe the pipe with a rag, apply sealant to the ribs of the gasket and install the pipe into the sewer drain hole.

Treat the second end of the channel with sealant and put it on the toilet neck. If you notice gaps, then be sure to cover them with sealant or.

On the outlined place under the toilet, install rubber gasket and apply a layer of silicone sealant to it. Install the toilet and fasten it securely.

The last step is to check the bathroom. To do this, drain the water from the tank several times and check if it flows out from under the structure.

An alternative solution - how to replace the corrugation?

Despite many advantages, plastic pipes have several disadvantages. Among them, a small wall thickness and brittleness in comparison with metal channels stand out. In addition, many residents do not like and appearance the entire product. In this case, you can choose a regular chrome pipe, which looks much better.

If there is no desire to buy and install corrugation, then you can go the alternative way. For example, you can install a toilet with an oblique type outlet. In this case, the latter should be located above the sewer socket. Installing such a design can be quite problematic. You can solve the problem by using polyethylene or PVC pipes. Take the pipe and connect one side of it to the toilet. The other part is connected to the sewer. To seal the connection, use rubber cuffs.

The second method of solving the installation problem involves heating the pipe. To do this, the pipe must be heated until it becomes soft. After that, pull the product over the toilet outlet as quickly as possible. Connect the other end of the pipe to sewer socket and apply sealant.

To connect a toilet bowl with outlet direct type a plastic corner can also be used for an oblique sewer socket. The shops are wide selection such elements. To prevent water from leaking out from under the corner, be sure to place a rubber seal under the toilet bowl.

Directly when buying, experts advise paying attention to the length of the corrugation. This is especially true for toilets in which the toilet is located away from the wall. On the one hand, the corrugation is able to stretch, however, if the product is strongly stretched, then its walls can become a little thinner. This will adversely affect the strength of the structure.

Masters recommend not to stretch the product immediately before you install it on the toilet. This can only be done when connected to the sewer. Otherwise, the outlet may sag, which will cause clogging of the system. When installing, make sure that the channel bends do not interfere with the normal drainage of water. In no case do not pinch the pipe, so as not to damage the soft product.

It must be remembered that the corrugation is not designed for heavy loads. Try not to clutter it with heavy objects, so that in the end the pipe does not burst.

Lightweight but durable plastic plumbing fittings have greatly simplified the installation of many appliances. In particular, the corrugation for the toilet bowl allows you to connect the outlet of this type of plumbing to the sewer outlet much faster and without much difficulty.

Do you want to install a corrugation with your own hands? We will tell you how to do this - the article describes the installation procedure for corrugations and options for connecting toilet bowls with different types of outlet. Also given mounting tips and recommendations for choosing the best corrugation.

Thanks to detailed analysis important nuances the connection procedure is quite accessible even to a non-professional.

Corrugation belongs to the class of spillway fittings. This is a durable stretch adapter made from polymer materials and shaped like an accordion. Its properties remain unchanged even when it is heated and stretched.

The corrugated pipe has the shape of a sleeve with a plastic cuff, which has a rubber seal inside. With its help, toilets are connected to the sewer with different types flush - oblique and horizontal.

Its dimensions are in the range of 21.2 - 50 cm. The end of the pipe with the outlet has a cross section of 11 cm, and the one connected to the outlet is 7.5 cm inside and 13.4 on the outer surface.

Varieties of corrugated pipe

Corrugations go on sale unreinforced or soft, reinforced with reinforced walls stainless wire‚ tough. The first are relatively cheap and have not very high strength characteristics.

Such property as flexibility is very important. It allows you to securely connect the toilet to the sewer receiving pipe, even if it is located on a different level.

Soft corrugation fits any design and is easier to install. The bad thing is that after a few years of operation, difficulties may arise with draining due to sagging of the corrugated adapter.

The reinforced pipe has much higher characteristics, it is more reliable and durable, but also more expensive. These corrugated pipes have a rigid branch pipe with a turn, and its continuation is a corrugation. They are indispensable when you need to connect a toilet bowl with an oblique outlet to the drain.

Detailed information about the types of toilet bowls and types of release is discussed in another.

Features of the choice of corrugations

When buying a corrugation for connecting a toilet, you need to choose the highest quality. This will reduce the possibility of leakage to zero and such a product will last longer. The difference in prices is small, so it's better to pay a little extra and save yourself from unnecessary problems in the form of the contents of the pipe on the floor.

Any comparisons of domestic and foreign corrugations are not in favor of the first. Our corrugation does not cover the pipe walls well. No tricks help - the domestic corrugation does not fit completely to inner surface sewer pipe.

Often the corrugated pipe forms waves, which causes a leak. Even professional installation will not help to avoid such troubles.

The technology for installing corrugations on the toilet is simple and does not require much effort. Important to choose suitable size flexible hose, focusing on the cross-sectional size of the riser

The best corrugated producing countries are Italy‚ Czech Republic‚ ​​England. Having visited the market, you can see that most of the products are delivered from China. Do not be tempted by their cheapness, they will not last long and what seems like savings will turn into additional costs.

When choosing a corrugated sleeve, you should look at the thickness of its walls. If the other characteristics are equivalent, then you should buy the one whose walls are thicker. It is bad that this information is not always indicated in the description attached to the product.

Some corrugated pipes are designed to hold an elastic band together with a plastic ring. There are models that provide direct connection- the elastic band is inserted into the end and fixed on the "herringbone". The second option is more reliable.

The procedure for connecting the toilet with corrugations

The work of connecting the toilet is not difficult, but a certain sequence of actions must be followed. It is more convenient to start installing the corrugation to the toilet bowl, both to the new one and the old one, even before it is fixed in a permanent place.

When nothing needs to be done with a product just brought from the store, then the outlet of the old device must be freed from deposits of cement or sealant.

The photo shows the sequence of connecting the toilet using corrugations. Some experts believe that it is not worth sealing the connection of the corrugation with the sewer, because. silicone can destroy rubber over time

You also need to clean the socket of the sewer pipe. If this place is not freed from the remnants of materials, it will be difficult to ensure the tightness of the connection.

  1. The end of the pipe, which is going to be connected to the sewer, is treated with silicone. The end of the outlet must be evenly blocked by a 50-60 mm outlet. You need to tighten with a turn, without allowing any distortions. To facilitate the process of tightening the corrugations, smear the rubber seal in the socket with soap.
  2. A corrugated pipe is inserted into the inlet of the system at one end, and the other end is connected to the toilet.
  3. Pour water into the toilet to check the joints.
  4. Mark the toilet attachment points on the floor by disconnecting the corrugation before that.
  5. Drill holes and coat with sealant.
  6. Attach the toilet to the floor. At the same time, the fixing bolts are attracted until the device stops staggering and becomes perpendicular to the floor. With increasing effort, you can split the base.
  7. Reconnect the adapter, process the joints with plumbing sealant and check them again for leaks.
  8. The screed is poured and the floor surface is finished.

The release form of the floor toilet can be vertical‚ horizontal‚ oblique. In each case, connecting the toilet bowl has its own characteristics. In old houses, vertical and oblique outlets are most common, and in new ones, horizontal ones.

To connect the toilet bowl to a sewer pipe, the outlet of which is in the floor, a corrugation with a socket bent at 90⁰ is suitable. For a plumbing fixture with a horizontal outlet, a corrugation with a 45⁰ socket rotation is mainly used.

It happens that in a bathroom with a small area it is necessary to place a lot of plumbing fixtures. To do this, it is necessary that there are many branches on the sewer pipe, and this is not always realistic.

The only way out is to use a toilet corrugation with a tap. It is the only alternative when the bathroom is located almost right next to the toilet.

It happens that for some reason the corrugation becomes unusable. It's easy to replace it. To do this, you don’t even have to dismantle the toilet, but you need to prepare rags and buckets.

Block the flow of water into the toilet drain, then disconnect the tube intended for the flow of water. The tank is freed from water and removed. The corrugated pipe is simply compressed and disconnected from the device. Next, take it out of the socket.

The corrugation for draining is a universal product. With its help, the toilet bowl can be connected both to the sewage system made of plastic pipes and to old pipes made of cast iron

A new pipe is inserted into the socket, squeezed, pulled over the outlet of the toilet bowl. All this can be done with a stretched corrugation. If it is extremely compressed, nothing will work. This is a nuance that must be taken into account even during the initial installation.

We have others on our site. useful articles with detailed instructions for installation of toilets various types and designs:

For all its merits, plastic corrugation is not designed for heavy loads, so it cannot be mounted inside the wall. With a large distance from the wall to the plumbing fixture, the length of the connector should be carefully selected.

The corrugation is stretched, but if this property is abused, the walls can become thinner and the strength of the structure will decrease. It is not necessary to stretch the corrugation before its installation - this will lead to sagging of the outlet.

Stretch it immediately before connecting to the sewer pipe. In order to avoid blockages, it is not necessary to allow sagging or counter-slope of the corrugations. When the sewer pipe and the outlet of the plumbing fixture are located relatively high, a support is constructed under the connector.

If the corrugation sags, a “pocket” will appear in it, where deposits will accumulate. This can lead to rupture of the walls of the connector. Stands or auxiliary clamps will help prevent such a consequence.

When the decision to install protective screen to mask communications, and use the fenced-off space as a place to store various little things, do not forget that a heavy object can damage the corrugation.

Before mounting the plastic corrugation on the toilet, take into account that the product standard sizes does not allow you to install it right next to the wall. Here it is better to use .

We must not forget about plumbing standards when choosing a slope. Can't turn reinforced pipe at a right angle. If the device occupies a non-standard position, a connecting element with an offset is used.

Before starting work, make sure that the corrugation is suitable for the parameters. It also needs to be checked for cracks. If, together with the corrugated pipe, it is also planned to replace the toilet bowl, then it is put on even before the installation of plumbing

The corrugation can compensate for a fairly significant displacement. Thanks to it, the device can be moved by a maximum of 200 mm. And also it can be deployed to any angle. To do this, use such an option as serial connection two corrugated pipes.

At the angle at which the corrugation is bent, you need to turn Special attention. With a large pinch, draining cannot be carried out efficiently. In addition to everything, the corrugation can crack at the pinch point.

Connection without the use of corrugations

If the outlet shapes of the toilet bowl and the sewer pipe match, you can do without corrugations. Connecting the toilet without the use of corrugations‚ follow certain rules. At the same time, an adapter is used, which is also called a pipe.

The installation method is chosen depending on the shape of the outlet of the toilet bowl: in the case of an oblique outlet, they are installed on the floor; with a vertical outlet, the toilet bowl is mounted into the wall at an angle of 90⁰; while horizontal - also into the wall, but at an angle of 30 to 40⁰.

Option #1 - Vertical Outlet Toilet

The model of such a toilet bowl is equipped with a siphon having an outlet pipe. Under this design, first mark the place, then install the flange with the lock.

The sewer pipe is mounted in its center and a plumbing fixture is installed. The toilet is rotated until it is fully fixed. The pipe takes its place automatically.

Such a scheme is good in that the wiring becomes invisible. pipes are hidden in the floor. This saves space. The downside is that to eliminate the leakage that has arisen, you will have to crack the floor covering.

Option #2 - horizontal release type

This release is directed back into the wall. Here you can not do without a sealing cuff. First, the toilet bowl is fixed to the floor with dowels. More about best practices fixing the toilet bowl to the floor we recommend to look here

Not every apartment can have a toilet of this design. The use of the scheme is possible only if there is a vertical sewer riser

Option # 3 - oblique toilet outlet

To connect using a plastic pipe, minium is mixed with drying oil and smeared with this toilet outlet. From above, a seal is made in the form of a resin strand. The seal is coated with red lead. The outlet is inserted into the sewer pipe and the toilet is mounted.

A sealing collar can also be used here. Having dressed it for release, the latter is placed in the socket of the sewer. Be sure to seal the connection.


Models of toilet bowls, in which an oblique outlet is implemented, are quite in demand among buyers. One of the significant advantages of this design is the ease of replacing the cuff if necessary.

Conclusions and useful video on the topic

Here you will see how to install a toilet with a drain and connect it using corrugations:

As you can see, the corrugation used to connect the toilet is small, but very important element systems. You need to choose it responsibly, and when performing installation, you must follow all the instructions.

Corrugation for the toilet: product options and their purpose

Previously, only one material was used to install the sewer pipe system and the toilet bowl - cast iron. Pipes, risers, elbows, a collector were cast iron, but this metal has not very many advantages for such a system. The fact is that cast iron is rough, that is, all sewer pipes quickly become overgrown with dirt and the need to clean them often arises. But over time, not only the connection scheme changes, but also the materials used for the production of various nodes.

Corrugation for the toilet, there are both plastic and cast iron. In houses built in Soviet time you can find a cast-iron corrugation of the toilet bowl. In our current time, to replace the cast-iron corrugations, they began to make plastic corrugations for the toilet.

Instead of difficult to install, heavy and not very high-quality cast-iron pipes, light, but very durable and high-quality plastic pipes are increasingly being used. One of the connection leaders household toilet from the outlet to the sewer socket is a special corrugation for the toilet, that is, a pipe of a special shape.

Such a corrugation is an adapter, which is made of thermoplastic materials that are stretchable and do not lose their strength. Corrugation refers to spillway fittings. It is a special flexible sleeve with a cuff, through which drains flow from the outlet into the sewer pipe. Today, the corrugation is produced with sizes from 231 to 500 mm, its diameters at the end are 110 mm (for a sewer riser), on the side connected to the outlet - 134 mm along outside and 75 mm on the inside.

Corrugated pipes-adapters are mounted quite simply on the toilet bowl; this does not require special experience or expensive equipment, which makes the corrugation so popular these days.

Pros and cons of using

Corrugation for the toilet bowl has numerous advantages that have made it the most popular recently:

  • very simple, convenient installation, which anyone can handle;
  • if necessary, displacement, transfer of the toilet corrugation - almost the only connection option;
  • when installing a temporary toilet, when repairs are still being carried out in the bathroom;
  • if the types of equipment outlet and the socket of the sewer system in the house do not match.

Not always corrugation for toilets is an excellent option for connection, there are some disadvantages of using it, which should be mentioned:

  1. Ordinary soft corrugation is not very durable, its walls are quite easy to damage. This must be taken into account during operation and installation.
  2. The corrugation for the toilet bowl can only be used in open areas, that is, its installation in the wall is impossible.
  3. Such pipes sag, that is, blockages are often observed during operation, especially if the angle of rotation is significant.
  4. There is one drawback that is not related to the characteristics of the pipe itself, but is quite important during installation. The problem is that the market today is simply littered with low-quality fakes, so you need to buy pipes only from a trusted supplier.

Appointment corrugations for the toilet

Corrugated toilet pipe has good flexibility. It can be made longer or shorter as it stretches well.

A modern toilet corrugation is sometimes the only way to perform installation in the required position. It is not always possible with the help of ordinary rigid pipes to make a connection to the sewer in the selected position or when using a certain model of it, if the socket is simply not intended for it. Let us consider in more detail in which cases the use of corrugations is required, what mounting options can be used, what types of corrugated flexible pipes are offered today by specialists.

Corrugation for the toilet bowl is used in several cases:

  1. If necessary, axial displacement of the toilet bowl in relation to the sewer socket. There are quite a few such cases today. This is the flooring tiles on the floor, which raises the equipment, that is, it is no longer possible to use rigid conventional pipes. There is an option when the plumbing equipment is simply transferred to another place, more convenient for use. In each such case, the outlet line of the toilet bowl and the socket of the sewer outlet will no longer coincide, which means that the use of a special flexible corrugation for the toilet bowl is required.
  2. The second case concerns the release itself and what type of sewer socket it is intended for. Manufacturers today offer toilet bowls with the most different types release, but, for example, old apartment buildings are intended only for installation of oblique release. Therefore, if you have purchased equipment with a horizontal or vertical outlet, you will only need a corrugated pipe to connect to the sewer system, which can bend at any angle, while maintaining its qualities.

Types of corrugations for the toilet

To connect a corrugated pipe for a domestic toilet, various types of it can be used. Such pipes are not only traditional soft, but also rigid, more reliable and durable. But, despite this, it is soft corrugation that is more popular today, since it is installed much easier and faster, the connection is made for any type of toilet outlet, since a soft corrugated pipe can be bent at any angle. Such options are more acceptable.

Today, manufacturers offer corrugations for the toilet bowl, simple, unreinforced and reinforced. For reinforced, rigidity is provided with a small diameter wire that reinforces the walls of the sewer pipe. This variety is more expensive than non-reinforced, but its service life is much higher, and the indicators of reliability and strength are excellent.

The toilet corrugation is a flexible corrugated pipe that is attached to the toilet drain hole.

Also, corrugated pipes for mounting a household toilet can be divided into short and long. In this case, the choice depends on how far the toilet is from the sewer socket. Experts do not recommend taking pipes that are too short in the hope that they will stretch end-to-end during installation. This option is quite risky, leaks are possible.

When choosing a corrugation for installation, attention should also be paid to what pipe diameter is needed, although manufacturers today are trying to offer standard solutions, that is, choosing exactly the type that is needed is quite simple.

Corrugation installation process

To provide correct installation corrugations for the toilet, you will first have to prepare tools such as:

  • perforator or drill with a percussion function;
  • ruler or tape measure;
  • silicone-based sealant;
  • flexible corrugated pipe of required length;
  • FUM tape (can be replaced with tow);
  • a hose for supplying cold water to the toilet;
  • toilet of the selected design;
  • set of adjustable wrenches for connecting water supply to the tank.

After the tools are prepared, you can proceed with the installation of the toilet bowl and its connection to common system house sewerage.

First you need to properly position the toilet, fix it on the floor surface. After that, the outlet is cleaned, as well as the socket of the sewer pipe. It is necessary to ensure that the inside of the socket is as clean and even as possible, knock off all the remaining cement with a chisel or a special nozzle on the puncher. Then wipe the bell inside with a dry rag.

Before you start installing the corrugations on the toilet, you need to make sure that there are no traces of mucus, dirt, cement and other debris on the socket and outlet, which can cause a defect in the adapter.

The corrugated pipe itself is very easy to install, a special rubber seal is pulled over the outlet. In this case, you can apply force, it stretches perfectly, after which it takes its previous position, tightening the knot.

To process joints to avoid leaks, it is recommended to use silicone sealant. The composition is applied in a circle, after which the corrugation is fixed. It is necessary to try not to displace it until the sealant is completely dry. Outside, it is completely useless to process the pipe, so do not forget about this most important step.

After that, you can fix the toilet in the chosen place so that it does not stagger or move. After that, the corrugation for the toilet bowl can be attached to the sewer socket. A sealant is also used here, which will not only protect against possible leaks, but also prevent unpleasant odors from entering the room, which is very important when using plumbing equipment such as a toilet bowl.

Cast iron socket pipes for connecting plumbing to the sewer are a thing of the past thanks to plastic products, which has a number of advantages.

Modern socketless pressure and non-pressure pipes, as well as VChGSh products, are equipped with an inner layer that significantly improves their technical capabilities.

A plastic corrugated pipe for a toilet bowl is cheaper than an analogue made of cast iron, has less weight and is more durable. Easy to clean, no caulking or fitting required.

In addition, they are simple and easy to install, which allows you to do it yourself, significantly saving on plumbing services.

However, it is worth paying attention to the fact that corrugated plastic pipes are used only for outdoor installation, only metal structures are suitable for walling into the wall.

Choosing a toilet corrugation

A corrugation, or cuff for a toilet bowl, is a plumbing element, which is a wide corrugated pipe made of modern thermoplastic that connects the toilet bowl to the sewerage system.

The procedure for connecting plastic fittings with pipes and a toilet hole is facilitated by a cuff located at the edge of the structure. Corrugated walls allow you to vary the size of the fixture up to 23-50 centimeters.

Before purchasing a product, you need to select a modification of plumbing equipment.

Let's take a closer look at these options.

Types of corrugations for the toilet

Corrugated plastic pipes have the following characteristics:

Softness / hardness. Rigid toilet corrugation is wear-resistant and strong. Soft fittings are rightfully considered universal, suitable for any type of bathroom (vertical, horizontal, oblique) and easy to install.

Reinforcement increases the service life of the corrugations due to the use of thin steel wire.

However, it is worth paying for additional reliability: the cost of such a product is much higher.

The length of the element varies within 23-50 cm. It is important to take into account these parameters by first measuring the length from the toilet bowl to the sewer pipe.

To avoid leaks, experts advise taking the design a little longer than the indicated distance.

Product dimensions

Corrugated plastic pipes for connecting plumbing have a diameter of 50, 100 and 200 mm.

The toilet corrugation is standard. The diameter of the cuff attached to the toilet is 13.4 cm from the outside, and 7.5 cm from the inside. 11 cm is the diameter of the sewer pipe hole.

Corrugation for the toilet bowl is available in any specialized point of sale selling sanitary ware. When buying, you should ask the seller for a certificate of conformity confirming high quality products.

How to dismantle the old structure

Before installing a new plastic corrugated toilet pipe, the previously installed structure should be dismantled. This process consists of the following steps:

  • prepare a rag and a container to eliminate possible leaks;
  • turn off the tap that regulates the water supply to the system;
  • unscrew the water supply hose;
  • empty the drain tank from the liquid;
  • remove the drain tank;
  • dismantle old equipment.

To do this, use the advice of experts:

If a old design stretched as much as possible, it is easy to remove it from the opening of the toilet bowl and the sewer pipe. The rest of the water is enough to drain into the sewer.

If the toilet is located in a corner, do not forget about the arc rule. Start removing it from the toilet and then from the sewer. The process will be easy and will not take much time.

If the bathroom is located too close to the sewer, you should remove it from the mount, and then release the pipes from the corrugated pipe.

In this case, you need to be extremely careful, since the toilet bowl can be firmly fixed to the floor (cemented).

It is worth dismantling it by striking with a hammer or sledgehammer on the neck. This must be done carefully, avoiding splitting the structure.

To avoid damage, never strike the sewer pipe. Having coped with the dismantling, clean the sockets of the sewer and toilet bowl. Install a special plug on the bell, which subsequently eliminates the stench.

Installation of a corrugated pipe

Installation of a corrugated plastic pipe is simple and accessible to everyone. One end of the corrugated pipe is inserted into the toilet socket, the other - into the sewer pipe with a five-centimeter tension on the outlet.

To prevent the ingress of water or air, the joints should be treated with a sealant.

The corrugated pipe installation process includes the following steps:

  • Thoroughly clean the toilet bowl and drain drainer from the remnants of the old mount.
  • Wipe dry the connection points from dust and grease.
  • Insert the corrugation into the toilet, moving it to the drain, insert the second end of the product into it.
  • Do not try to pull the corrugated pipe too hard. This will help increase its lifespan.
  • Screw the toilet to the floor.

To check the operation of the installed structure, make several test descents.

If no water leaks were found in the corrugation and drain hose, the drain structure works, then the installation was successful.

Non-pressure plastic corrugations greatly simplify the process of connecting plumbing equipment to the sewer system. Previously, socket pipes made of cast iron PTCHK (including their fittings) were used for this purpose, which were regulated by GOST 6942-98. Now they are being confidently replaced by plastic fittings, which have undeniable advantages.

It should be noted that modern socketless pipes (both pressure and non-pressure), as well as ductile iron products, have a special inner layer that allows them to improve their technical characteristics. An example is the products of Pam-Global, Duker, SML.

The corrugation for the toilet bowl is much better cast iron products, since it has less weight, lower price, longer service life, it is not difficult to clean such fittings in order to connect cast iron pipe with plastic, chasing and fittings are not required. In addition, if after the repair in the bathroom the floor level changes (as a result of which the toilet bowl rises), the corrugation will not need to be replaced.

Note that the corrugated plastic pipe is intended only for outdoor installation, it cannot be embedded in the wall; cast iron or metal pipe fittings are used for this purpose.

How to choose

Before you buy a corrugation to connect the toilet, you need to decide on its type and size. It makes sense to consider this issue in more detail.

Kinds.

The corrugations used to connect the toilet may differ in the following parameters:

  • elasticity, corrugated pipe is soft and hard. The latter is more durable and wear-resistant. Soft corrugations are universal, they can be installed on any toilet, regardless of what type of outlet it has (vertical, oblique or horizontal). The good elasticity of such a pipe greatly simplifies installation;
  • reinforcement, to strengthen the rigidity of the structure, thin steel wire can be used; such a corrugated toilet pipe has a much longer service life than conventional counterparts. True, and the price for it is higher;
  • length, it can vary between 20-50 centimeters. When making a choice, it is necessary to take into account the distance from the toilet to the place where you want to embed the corrugation. We recommend taking the length with a margin, this minimizes the risk of leakage.

Dimensions.

Despite the fact that corrugated pipes used to connect various plumbing equipment can have a diameter of 50, 100 or 200 mm, the dimensions of the toilet corrugations are usually standard. The figure below shows where and to what extent there may be discrepancies.

It will not be a problem to buy a corrugation with the necessary parameters, there are many networks of specialized stores selling plumbing equipment. Moreover, they are in almost any city, whether it be Pyatigorsk or Chelyabinsk.

We remind you that a quality product always has a certificate of conformity, of course, the cost of counterfeit products is much lower, but such dubious savings can lead to expensive repairs being required. beware retail chains where counterfeit products are sold.

Once you have made your choice, you can proceed to the installation process, which, as a rule, begins with the dismantling of the old plumbing equipment.

Dismantling

Before installing the corrugation and connecting it to a new toilet bowl, it is necessary to dismantle the old one. For this work, you need to stock up on rags and prepare a bucket (or rather a few).

The sequence of actions of the preparatory process:

  • turn off the supply of water entering the chamber of the drain tank;
  • unscrew the water supply tube;
  • drain the water from the tank;
  • remove the drain pan.

Now you can proceed directly to dismantling. Immediately you need to warn if the toilet was operated long time, then there is a high probability that it has a reliable "grounding", that is, it is cemented. If so, it will be difficult to remove it without damaging it, and when the toilet neck is also packed with rags and paint, it is almost impossible.

In such a situation, it will be necessary to apply a strong blow with a hammer or sledgehammer of the target to the neck of the toilet in order to split it. The vibration created by the impact acts on the cemented base of the structure, which will help in the work.

Important! Do not hit the sewer pipe, especially if it is made of cast iron. This brittle material can shatter or crack. Note that it will not work to close up such a crack, as a result, before installing the corrugation to connect a new toilet bowl, you will have to change the sewer pipe. This will cause additional difficulties.

After the neck is destroyed, we proceed to detach the structure from the floor, for this we try to swing it. If this does not work, we take a chisel and a hammer in our hands and knock the cement off the base. In the process of this, the toilet bowl may crack, from which water will begin to flow, or completely break (there will be even more water), in these cases a bucket and rags will help us.

After separating the structure from the floor, we knock down the remaining cement from it until the surface becomes even. At the final stage, it is necessary to clean the socket by removing the necks from it. For this operation, you can use an old screwdriver. When the pipe is completely cleaned, a plug is put on it so that an unpleasant smell does not spread in the apartment.
