Correct installation of corrugations on the toilet. Rules for replacing corrugations on the toilet from dismantling to installation

Many years ago, installing a toilet was complicated by fitting the socket to the outlet of the sewer system. The cramped area of ​​the bathroom and heavy cast-iron pipes turned the work into a long and laborious work of a whole team of workers. Thanks to such a connecting element as a corrugation, the situation has changed radically. Now the introduction of new technologies and available materials has greatly facilitated the connection of this device. Today we will talk about how the corrugations are installed on the toilet with our own hands.

Definition and classification

The corrugation is a kind of connecting element, which is made of plastic with "accordion" walls. It is thanks to this design that it can be stretched to the size you need. That is, the corrugation serves to connect the toilet outlet to the sewer system. With its appearance, you can install the toilet at the desired distance from the riser without further changing the floor level.

Today you can find a variety of corrugations, which differ in material and appearance. Now we will consider the main characteristics that you need to pay attention to when choosing this device.

According to the degree of elasticity:

  • Soft. This option is the easiest to install due to the fact that the soft corrugation is suitable for toilets with different outlets.
  • Rigid. The product is not mounted on all toilets, but only on those that are ideal.

Important! Rigid corrugation has increased wear resistance.

By the presence of reinforcing elements:

  • Without reinforcing insert inside the structure. They are most often used because of the low pricing policy.
  • With thin metal wire. A product with this configuration will serve you for many years. Of course, reinforcement will cost you dearly, but your expenses will be justified.

By lenght:

  • Small. In a compressed state 212 mm, and in a stretched state - 320 mm.
  • Big. Compressed 285 mm, stretched 500 mm.

Important! The choice of product will depend on the interval between the riser and the toilet. In any case, you need to take the corrugation with a margin.

Advantages and disadvantages

So we come to the discussion of strengths and weaknesses corrugations. Now we will consider everything separately.

Pros:

  • The ability to connect the device in absolutely any conditions (with a small area, non-standard location of the toilet bowl).
  • Easy installation. Anyone can handle the installation of corrugations without special plumbing skills.
  • The ability to disconnect the device at any time. In case of an emergency or just out of necessity, you can easily remove the toilet and then reconnect it to the same corrugation.
  • The diameter of the corrugation fits any toilet bowl socket.

Important! Do not get lost in the variety of prices for corrugation. In any case, you need to pay attention to the highest quality plumbing element. By purchasing plastic model at a low price, you risk getting a product of poor quality, which will shorten its life.

Minuses:

  • Thin material, the integrity of which is easily damaged.
  • Unattractive appearance.
  • If the pipe is too stretched and incorrectly installed, the product may sag, which will lead to clogging of the corrugations.
  • A short service life of a plastic plumbing element compared to metal counterparts.

Do-it-yourself toilet corrugation replacement

So, we have come to the most important thing - how to put the corrugation on the toilet without the involvement of outside help. Step-by-step instruction looks like this:

  • We clean the outlet and socket of the toilet bowl. We get the cleanest and most even surface of the socket.
  • We cut down the remains of cement and the previous release with a chisel.
  • We wipe inner part socket and outlet surface with a clean, dry cloth. There should be no residue of runoff, mucus, cement dust and other small debris.
  • Now we set the toilet bowl to its working position for applying fastening marks, taking into account the corrugations.
  • We put the corrugation on the toilet, pulling it well to stretch the rubber seal.

Important! You must understand that the less the corrugation is stretched, the less likely it is to sag. Otherwise, debris will accumulate in it and stagnation of water will form.

  • We drill the previously marked places for fasteners. If there is a tile on the floor, first we drill it with a drill through the tile, and then we drill the existing ceilings in the concrete with a puncher. We put in place suitable plastic dowels.
  • We seal all the cracks around the sewer pipes with sealant. We apply sealant in a circle to the outlet, stretch the corrugation, which we do not displace until the protective composition hardens. The most important thing is that the sealant is inside the toilet bowl socket. Now the pipes won't leak.
  • We put the toilet in place, tighten the screws well until the product stops staggering.
  • To check well-sealed cracks, pour a bucket of water into the toilet. If the outer pipe remains dry, the job is done correctly.
  • We smear a little cement mortar around the circumference of the bottom of the toilet. To do this, you can use a sealant.
  • We remove the remnants of the protective coating with a knife.

Work is ready! Now you know how to install the corrugation on the toilet.

How to choose a corrugation for the toilet?

So. Let's answer the question on the correct selection of corrugations for the toilet. Here are some tips for you:

  • As mentioned earlier, you should not buy cheap corrugation of dubious quality. Give preference to a more expensive plumbing element that will serve you for decades.
  • It is better to buy products not domestic, but imported.
  • It is advisable to purchase a corrugation with reinforced wire in the middle of the structure, since it is such products that will be able to maintain their original wear resistance.
  • Calculate in advance the interval from the socket of the sewer pipes to the outlet of the toilet bowl so that the elastic element does not stretch or sag.
  • It is worth giving preference to a product with thick and rigid walls so that they perform their main function longer.

Important! If the corrugation is exposed to chemical toilet cleaners, it may leak. To do this, you do not need to dismantle the toilet. It is enough just to replace the old element with a new one by removing the damaged pipe, cleaning it and removing the old layer of sealant


More recently, to connect the toilet to sewer system significant effort was required. It was necessary to dock the toilet with a cast-iron pipe, in order to exclude a possible leak, the joints were isolated concrete screed. But due to the fact that the surface of the inner, working, part of the cast-iron pipe has an abrasive surface. This contributed to the "growth" of sewage on the bends of the pipe and at its inclusion in the main sewer pipe. Sometimes it was not easy to get rid of such "growths" and often the pipe was simply changed. Where, very often, the dismantling of the pipe led to a breakdown and a change in the toilet itself.

But since then, technological solutions in plumbing have changed significantly. They have become less expensive and more accessible to a wide range of the layman. Connect yours today white swan To central system even the average layman without deep skills in this topic will be able to sewer.

What is a corrugation, why is it needed at all?

Corrugation is the collective name for pipes made of plastic, with a bell-shaped design that makes it flexible. The corrugation is crowned with a plastic cuff with a rubber seal inside the pipe, on the one hand, and a plastic "nose" on the other.

Corrugated pipe connects the toilet to the sewer pipe. Suitable for connecting toilet bowls with both oblique and horizontal flush.

Depending on the purpose, corrugated pipes are distinguished by types:

  • Soft: pipes without a rigid, reinforcing base. They are relatively inexpensive, due to them you can minimize the miscalculations made when installing the toilet. But when elongated, the thin walls of this pipe break easily. Also, over time, the pipe can sag, which will lead to drain blockages.
  • Reinforced: corrugated pipe reinforced with iron wire. It is much more stable than soft and more durable in service. But much more expensive than soft.
  • Rigid: the branch pipe of such a pipe is rigid. A small turn of the pipe is laid in it, its corrugation continues. It is used when connecting a toilet bowl with an oblique outlet to a sewer pipe.

Preparation for work

In any, even the most trifling matter, preparation is important. Because the quality of the work performed depends on it. First of all, you need to start with the preparation of the tool and related materials. You may not need the entire tool in the process of work, but it is better to be prepared for any difficulties that may arise unexpectedly than to look for the fifth corner later.

So better check if you have on hand now:

  1. Screwdriver
  2. Spatula with hard handle
  3. pliers
  4. Hammer
  5. Roulette
  6. sealant
  7. Enameled bucket of patience and good mood)))

If your sealant package has already been opened or partially used. Check if it has dried out since the last use.

If everything is there, we can start.

Installation of corrugations on an already used and brand new toilet

http://truddoma.ru/wp-content/uploads/2012/10/voda-i-remont-kvartiry-3.jpg - The process of installing corrugations on the toilet, which was used earlier.

After opening the corrugated pipe package, carefully read the instructions on how to install the corrugated pipe on the toilet, because depending on the modification, the installation procedure for your particular pipe may differ significantly from that described here.

If you are planning to replace an old pipe on a working toilet with corrugation, first make sure that the water supply to the toilet is turned off. Having dismantled the old pipe, you need to carefully clean 3-5 (if it is, of course, possible in your case) centimeters of the pipe coming out of the toilet from dirt and residues of dried sealant. If it is plastic, which is very rare, you can use a spatula with a hard handle. If faience, try to pick up the remnants of the layers with a screwdriver or sharp knife. The surface of the pipe must be cleaned as much as possible in order for the corrugation collar to tightly clasp it. This will help you avoid odor leakage and possibly sewage.

After making sure that the toilet pipe is clean, evenly stretch your corrugated pipe, for a length equal to the distance - from the end of the outlet of the toilet pipe, to the entrance of the end of the corrugation into the sewer pipe. Put the corrugation cuffs on the outlet of the pipe from the toilet bowl, having previously lubricated its inner rubber part with a sealant. Apply the sealant in an even layer, it should not be much, but its lack can lead to leakage. Pulling the cuffs on the toilet pipe by 3-5 centimeters with semi-rotational movements, try to evenly stretch it, the corrugation. After inserting the end of the corrugation into the sewer pipe, scroll it a little, but do not put too much emphasis so as not to damage the joint. Pick up sealant residue if it protrudes from the cuff.

The process of installing the corrugations on a new toilet is identical to the one described above, with the only difference being that you do not need to clean the remaining dirt from the outlet pipe of the new toilet.

Typical mistakes when installing a corrugated pipe

The most common mistake that novice plumbers make when installing corrugations is to overstretch its main part. During the installation process, it is better to undertighten the body of the pipe a little than to make it too long.

Sprawled on the floor, she will collect sewage in herself, exuding an unpleasant smell. Due to this error, made at the very beginning of the operation of the corrugated pipe, its throughput is significantly reduced. Thin walls, which can be accidentally stepped on, easily break and crack, and then you will have to collect sewage manually, and urgently change the corrugation. Therefore, it is very important to pay attention to this during installation.

Do it right the first time

Picking up correct type corrugated pipe, having prepared the necessary tool and related Consumables By analyzing possible errors and carefully reading the instructions on how to install the corrugation on your toilet, you can always count on a high quality result, even if you have never done this before.

Previously, the entire plumbing system was made of cast iron, it is quite reliable, but the downside is that the pipes were clogged with dirt, which brought a lot of inconvenience. Changing the toilet was very challenging task, since it was necessary to pick it up at all entrances and exits. Times have changed, along with the requirements for toilet components, pipes have begun to be made of plastic, which is easier to change, it looks more attractive, and there is no need to contact plumbers for replacement. It was necessary to come up with suitable adapters for them. One of these adapters is the corrugation.

Corrugation is a plastic corrugated pipe, it can also be called a sleeve or cuff. This is one of the most necessary and sought-after plumbing parts, designed to ensure uninterrupted draining of water in the toilet. The corrugated pipe remarkably (due to its design) stretches to the required size and joins the sewer. It is a very reliable plumbing element, although it has some disadvantages.

The corrugated pipe belongs to the drainage system. It differs from a solid pipe in flexibility, and from a drain cuff - in length. This is a plastic sleeve through which water flows into the sewer system.

Corrugation differs in its characteristics:

  • Rigid - distinguished by its wear resistance;
  • Soft - suitable for all types of toilet bowls;
  • Reinforced - in its design there is a thin wire;
  • Unreinforced - speaks for itself, it is not reinforced and cheaper;
  • Short - about 20 cm in size;
  • Extended length - about 50 cm in size.

This element has different sizes from 23 to 50 cm, and its diameter is 13.4 cm from the cuff side, where it is put on the toilet bowl socket, on the other hand, where it is inserted into the outlet of the sewer riser, it is 11 cm.

It is selected based on the type of toilet bowl, the distance between the latter and the sewer, and the preferred service life.

You can find this necessary element in any store that sells plumbing equipment. It is better not to save on such a necessary thing as corrugation. Savings can lead to serious damage, which will bring both a lot of inconvenience and spoiled mood, as well as the need for expensive repairs. Retail outlets can provide a certificate of conformity if the product is of high quality.

The nuances of installing corrugations on the toilet

After choosing and buying a corrugation, you can begin to install it. The corrugated pipe will differ in size and diameter, as it is installed on a different plumbing structure. You need to start by dismantling the old parts and installing new elements.

Instruction:

  • Drain and shut off the water;
  • Remove the tank body;
  • Disconnect the old corrugation from the side of the toilet;
  • Make sure that the new one is intact and of the required size and diameter;
  • Install a new corrugation, attach to the toilet, then to the sewer.

If you disconnect the old corrugation first from the toilet, it will be possible to drain the remaining water into the sewer. This sequence is especially important if the old corrugation is deformed, that is, stretched, or if it was installed at an angle to the pipe and its dismantling can be complicated. In the case of a compressed position of the corrugations, you will first have to dismantle the toilet itself. All this must be taken into account when connecting a new corrugation, since it will need to be changed over time. In order not to complicate your work, it is better to think about it in advance.

If you are installing a new toilet bowl and corrugation, first you need to connect the pipe to the drain hole, then install the toilet bowl, then connect everything together to the sewer. This will make it easier to install without any extra effort.

The installation of the corrugations itself is a simple procedure that you can handle on your own, without resorting to the help of a professional. The edge of the corrugation, on which there is an inner membrane that provides a tight connection, is put on a clean toilet pipe. To ensure greater tightness, the outlet of the toilet bowl is coated with sealant, then the wide end of the corrugation is coated with silicone. You need to dress it evenly and symmetrically, which will simplify the work further. Then leave the entire structure until the silicone dries. Then the other edge of the corrugation using the sealing ring should be installed in the sewer pipe. Before installing a new corrugated pipe, the old one is cleaned of dirt, sealants, rust and other existing debris. To be sure, the pipe must be smeared with silicone in the system. In order to check whether everything is airtight, after the silicone has dried, water is poured into the toilet (into the tank or the toilet itself). Correctly installed corrugation does not flow.

Ways to install a tap for the toilet

There is another type of sewerage connection using a tap. Connect the outlet (background pipe) in 3 ways that are suitable in a given situation, depending on the location of the elements.

What are the connection options:

  • Horizontal release hanging type- the pipe runs parallel to the floor;
  • Vertical release - fits perpendicular;
  • Oblique outlet - installed at an angle.

Horizontal release is used most often. Plumbing parts are attached to the wall. Sewerage is connected to the toilet with a sealing cuff. The vertical outlet and outlet are directed downwards and a siphon is located in the bowl. So you can install the toilet at the right angle. It's all very easy to install, you need to markup, and mount a flange with a lock on the floor. Do-it-yourself installation of the sewer pipe must be carried out in the center of the flange. The toilet bowl is installed on the flange by turning it to fix it.

At the same time, it is necessary to press the outlet pipe against the sewer pipe.

The sealing ring will ensure the tightness of the connection. The oblique outlet is connected with the application of a sealing winding. Winding is carried out with the help of a linen strand, smeared with drying oil, which must be mixed with red lead. The winding is made not reaching the end of the pipe by 0.5 cm. Next, you can install the toilet bowl and fix it, then insert the pipe into the sewer and fix the connection. Connecting plumbing to the sewer is not a difficult task, you can easily cope with it without being a professional in this matter. It is especially easy to do this using a corrugated cuff, and connecting with a tap is a more difficult job.

Instructions: how to install the corrugation on the toilet

To install an old toilet, you will need to clean it of old cement, dirt, smeared aggregate. It must be clean so that no deformation of new plumbing parts occurs.

To install the corrugations, you will need tools and a little time:

  • Drain, connecting, flexible corrugated pipe;
  • Roulette;
  • Sealant.

The latter is necessary to avoid leakage of the toilet. It is necessary to install the toilet in the planned place. Decide where you will need to drill the tiles and mark these places.

After determining where to drill, the toilet can be temporarily removed to make holes to secure the structure. Then put and strengthen the toilet.

You can start installing the corrugations, for this you need to coat the sewer pipe with sealant. Then install it on the outlet and on the sewer, after the sealant dries, you can check if everything is working as it should, to do this, draw water into the drain and check if it is leaking. If everything is sealed, the installation is complete.

How to change the corrugation on the toilet: rules

Corrugation replacement is sometimes required here and now, and the manufacturers made sure that it was not difficult to replace it. Corrugation is an adapter from the toilet to the sewer. Taking it off and putting it on is not difficult.

There are cases in which another pipe cannot be installed:

  • If the toilet is installed with a slight offset;
  • If the wrong type of toilet is installed, which was;
  • If a specific model with unsuitable dimensions.

The corrugation also has some disadvantages, it has thin walls, therefore, it is easy to damage it. The pipe looks more profitable than the corrugated one. It is not difficult to shorten it, and when stretched, it can sag. The design of the corrugated pipe can accumulate debris, both inside and outside.

With the usual replacement of a corrugated pipe, you need to dismantle the old one and prepare everything for installing a new one. You can clean the toilet bowl from cement with a chisel. If you do not remove everything that has accumulated on the old toilet and sewer system, installing a new one will not be able to install everything as it should. The whole system can just leak. Debris and old sealants are removed.

After that, you can put a new corrugation on the prepared place, this should be done carefully so as not to damage the new pipe.

It is necessary to install a new corrugated pipe once, and do not remake it, the following installations may damage the sealing of the rubber seals. Basically, this is manifested in corrugated pipes at a low price, or the low quality of this element.

Installing corrugations on the toilet (video)

If leaks occur during the installation of a corrugated pipe, then you will have to apply a sealant, or install a new one, which is desirable. In order not to change this part often, it is better to choose a good quality one.

Examples of corrugations for the toilet (photo)

With the development of plumbing technology, all the details of our daily life become simpler, easier, better. In the installation of the toilet, materials and equipment are also used to make everyday life processes more convenient and easier.

More recently, the word to change the toilet bowl or corrugation caused a negative reaction, since it was necessary to disassemble half of the sanitary unit in order to perform such a seemingly simple operation. Now it is much easier to do this, thanks to the appearance of corrugations for the toilet.

No toilet bowl can perform its functions without such structural element like a gopher. The main body of the corrugation has a springy shape.

On one side of the corrugation there is a branch pipe, which is intended for connection with the toilet sewer outlet, and the other end of the corrugation is intended for docking with the sewer pipe and has the shape of a ring with a herringbone sealing gum.

Corrugations come in different diameters. Before buying a corrugation, you need to know the exact diameter of the toilet pipe. Corrugation is the main minimum component of the toilet bowl configuration, the most the best option purchases of corrugations will be a simultaneous purchase along with the toilet.

Then the option is excluded that you buy a corrugation of the wrong size.

In addition to the corrugation, the toilet can be connected to the sewer using:

  • - straight or eccentric coupling. It is used if the outlet from the toilet is located directly next to sewer pipe;
  • - plastic branch or branch pipe with cuffs. It is set if the distance from the toilet bowl to the entrance to the sewer pipe is at a short distance, a little to the side;
  • - soft or hard corrugation. It is installed when the toilet is located opposite the toilet, but some obstacles prevent the entrance to the sewer pipe or it is necessary to turn the toilet at an angle.

In modern conditions, the removal and installation of a new corrugation turns into a game process. This is due to new technologies and materials that are used in the production of corrugations and component connections to it.

When choosing a toilet corrugation that needs to be replaced, it is preferable to focus on a quality manufacturer. It is unnecessary to save money by buying corrugation from a dubious manufacturer.

As practice shows, after some time, cheap corrugations often fail, the material from which they are made quickly dries out and loses strength.

There are different situations and ways to remove the old corrugation from the toilet. Replacing the corrugation will be easy if:

  • - corrugation, which is installed as stretched as possible. It must be pulled out of the toilet pipe, and then from the sewer pipe pipe. By doing the operation in this sequence, you can easily drain the remaining water from the corrugation into the sewer;
  • - the toilet is installed at an angle. In this case, the arc rule applies, in which you can also easily pull out the corrugation first from the toilet, and then from the sewer pipe.

To remove the corrugation, which is installed at the maximum tightened distance between the toilet bowl and the drain pipe into the sewer, it is necessary to remove the toilet bowl itself from the mounts.

Then remove the corrugation in the same sequence. After doing such processes, you can install a new corrugation, the installation of which is carried out in the reverse order.

Connecting a sewer pipe to a toilet bowl seems to be a simple matter, but there are some relative difficulties in this process.

There are 2 cases when corrugation is needed:

  • - if the toilet needs to be installed offset to the side or at a certain angle, relative to the bathroom. For example, if the floor level has increased or new equipment has been added ( washing machine), and without displacement, the toilet will be inconvenient to operate;
  • .- if the owners mistakenly purchased a toilet bowl with a smaller or larger diameter than the corrugation. Such a situation can arise when they buy an imported toilet bowl with a direct outlet, and the sewerage system in the apartment is laid out under an oblique installation.

The corrugation installation process goes through the following points:

  • - it is necessary to carefully clean the toilet bowl from the remnants of old connections and sealing gum. The same operation should be done with the drain of the sewer pipe. If to seal the old corrugations were used cement mortars, they can be easily knocked down with a chisel and a hammer;
  • - then you need to wipe dry the toilet pipe and the sewer drain pipe with a dry rag or washcloth. There should be no dust, greasy residues of sealant or other means that were used to install the old corrugation;
  • - then you need to insert the corrugation into the toilet, and then move it to the drain pipe and push the corrugation into it;
  • - the less the corrugation is stretched, the longer it will last;
  • - after all the operations done, we fasten the toilet bowl to the floor.

From the author: hello dear readers! Long gone are the days when the toilet was connected to the sewer only with a terrible-looking cast-iron pipe. Modern market offers us many kinds of connection materials: plastic and fan pipes, eccentric, corrugation.

Each of them has its own advantages and disadvantages. Plastic, for example, is very durable and reliable. But it requires the most accurate installation, the slightest distortion will lead to the fact that constant leaks will be observed. In addition, the appearance of such a pipe is not very pleasing: it is usually characterized by a gray color, which does not harmonize well with ordinary white sanitary ware.

The fan pipe saves in case of low bandwidth riser, but at the same time it is highly fragile and difficult to install. An eccentric is only suitable in some cases.

The most popular material is corrugation. This is such a relatively soft pipe, the outer surface resembling an accordion. It is low cost and easy to install. Nevertheless, some people still sometimes have a question about how to install the corrugation on the toilet with their own hands so that it lasts as long as possible. We will talk about this in today's article.

Which toilet bowls are corrugated suitable for

To understand whether a corrugated pipe is suitable for a sewer, you need to pay attention to the location of its outlet. There are three options:

  • horizontal;
  • oblique;
  • vertical.

The horizontal outlet is parallel to the floor, and with an oblique one, the pipe will go at an angle, while the sewer hole is located below the outlet. With both options, a corrugated pipe is perfect.

The vertical outlet is located perpendicular to the floor. Until recently, this type of connection was used mainly in European countries and in the United States of America. But in recent years, it has been increasingly used in our new buildings.

And no wonder, since the system is very convenient. Firstly, there is no need to tie the location of the toilet bowl to a specific point on the wall, and secondly, such a drain causes the least problems, since the contents of the sanitary ware go down without delay. In general, the method is excellent, but it requires a rigid connection, so a corrugated pipe is definitely not suitable here.

Advantages and disadvantages of corrugated pipe

If your toilet's outlet location allows you to use corrugated, then let's look at its pros and cons so you can make an objective decision.

As mentioned above, such a pipe is inexpensive and easy to install. Plus, it bends really well. That is, if you want not in front of the sewer hole, but somewhere on the side - no problem, the corrugation will serve as an excellent adapter.

But at the same time, it should be borne in mind that even the minimum length of the product on the market may be excessive for your particular situation, and trimming and fitting in this case is impossible.

In addition, there are other disadvantages. For example, the outer surface of a pipe has many small folds. Naturally, dust and dirt are actively clogged in them, which makes cleaning in the bathroom even more of a pleasure. Cleaning this harmonica is quite a chore.

Another disadvantage is the softness of the material. The product is not among the most durable, so it can be damaged quite easily. In addition, it can stretch and sag, thereby retaining the flushed contents of the toilet in one area.

First, it provokes the appearance of unpleasant odors. Secondly, the stretched corrugation becomes thin, so it can easily burst, and all the accumulated contents will end up on the floor.

However, the problem of low strength and the possibility of stretching can be solved by a careful approach to installation. Also, for greater confidence, you can purchase not a simple, but reinforced pipe. Its walls are reinforced with metal wire, due to which the product acquires increased strength. True, the cost of such an option is higher than a simple one.

Mounting procedure

The first step is to prepare a sewer hole. In order for the corrugation to stand up qualitatively, it must be clean and smooth. If you are going to do installation work in a new building, then, of course, no preparation is needed, since all the pipes there are new.

But if we are talking about an old house, then, most likely, earlier there was installed cast iron pipe from the toilet to the sewer. Moreover, usually the toilet outlet was built into the cast iron tightly, this was done with the help of.

If you have just such a case, then you will have to change the entire toilet. You can read about this entire procedure in other articles on our portal, but here we will talk exclusively about working with the drain.

Sewer pipe preparation

So, we have a cast-iron knee in which the toilet is cemented. We take a hammer and just break the sanitary ware right at the pipe. Before doing this, be sure to put on safety glasses so that the fragments do not get into your eyes.

Now it is necessary to remove cement residues and various hardened deposits from the inner walls of the pipe. To do this, we again need a hammer: gently tap the cast iron on all sides with it. Do not overdo it, otherwise you can split the pipe, since old cast iron sometimes surprises with its sudden fragility.

When you get rid of all global deposits and other interference, treat the pipe from the inside with a cleaning agent such as toilet "Duckling". Let it work for about 10-15 minutes, and then thoroughly scrub the walls using a wire brush.

Finally, wipe the cleaned surface with a rag. The most important area that should be given more attention at all stages of cleaning is a piece of pipe at the very exit, about five centimeters. It is his condition that will directly affect the quality of docking with the corrugation. Therefore, this area must be properly prepared, absolutely clean and smooth.

Corrugation installation

So, the drain is prepared for docking, you can proceed directly to the installation. Please note that the corrugation should be a third longer than the distance between the outlet and the sewer hole. Therefore, before buying, do not forget to take the necessary measurements.

For installation, we need the corrugated pipe itself, rubber cuffs, seals and silicone-based sealant. The procedure is extremely simple.

  1. Applying a thick layer silicone sealant to the edge of the sewer.
  2. We install a rubber cuff-seal in this place.
  3. We are waiting for the silicone sealant to completely dry, it usually takes about two hours. A more accurate time is indicated on the package. Until the moment of drying, try not to touch the pipe at all, so as not to disturb the reliability of the connection with the sewer.
  4. Now find the rubber tip located on the opposite end of the pipe. It also needs to be coated with a silicone layer.
  5. Pull this rubber tip over the toilet pipe and wait again until the sealant has completely cured.

Finally, test the system: draw a full tank of water several times and drain it, while carefully inspecting the corrugation for leaks. If none are found, then congratulations - you did it!

Important note: if during the installation process it turned out that the corrugated pipe needs to be stretched, do it evenly along the entire length. If you stretch any one section, then in the end you will get the very sagging that was mentioned above.

I am sure that if you follow all the nuances described in the article, you will successfully solve the problem of connecting a toilet bowl to the sewer using corrugations. Just in case, watch the video as well, so that the knowledge is definitely fixed in your head. Good luck!
