Not so long ago, sewer communications consisted mainly of cast iron parts. Cast iron pipes were connected to the toilet, which were considered very reliable and durable. However, in practice, it turned out that such pipes were practically overgrown and clogged with dirt, which made their further operation impossible. Thus, gradually progress has reached modern high-tech materials such as corrugation. But even latest species materials need to be replaced over time. Thus, a new problem arises before the man in the street -. Consider how to make it yourself.

What is corrugation?

Toilet bowls and pipe fittings have been constantly changing. Consequently, it was necessary to adapt to more and more new design solutions. To this end, manufacturers began to produce new high-strength thermoplastic products. Thus, the corrugation has become a part of everyday life and has become a necessary and important part of the toilet bowl design. It is she who serves as the transitional element that.

The direct responsibility of the corrugated pipe is to divert wastewater into the riser, from where it will already enter the sewer system. Distinctive feature corrugation is its flexibility and ductility. The corrugated tube can be easily stretched. It is clear that such properties made it much easier and quicker to install and connect the toilet to the system.

All this became possible thanks to the materials from which not only the corrugated pipe itself is made, but also the fastening auxiliary parts to it. Let's figure out which corrugation is suitable for use in toilets and how to change it if necessary.

Types of corrugations for the toilet

Corrugation is a tube with a corrugated surface. At one end there is a nipple that connects the toilet to the sewer, and at the other end is a ring-shaped nipple with a Christmas tree rubber band that serves for sealing.

Most often on the market you can find a corrugated pipe made of two materials:

• Rubber;
• Plastic.

Depending on what material the corrugation you purchased is made of, you can judge its properties. However, the peculiarity is that it can be stretched to a length of almost 1 m, and also bend wherever you need it. This allows you to place plumbing fixtures at either end of the bathroom, wherever you want.

So, what types of corrugated pipes exist:

1. Reinforced is quite tough, therefore, when choosing it, you need to take into account the structural features of the toilet. It contains a wire, which stiffens its walls. This type of product will cost a little more than others where the wire is not used, but it will also last longer.
2. Mixed - suitable for non-standard toilet installations. For example, if the designer decides that the toilet should lag behind the wall by a certain distance.
3. Drainage is the most versatile option among all. With the help of such a corrugation, the toilet can be connected to plastic pipeline, and to the outdated, stuffed with various fittings made of cast iron. It is mainly used by those who do not want to think about how the corrugation fits to the chosen model of plumbing.

In this case, it cannot be said that some kind of corrugation is better or worse. It's just that each of its types is suitable in one particular case. But be that as it may, when buying, you need to ensure that the product has a dense structure and does not have defects.

How to make the right choice

In the store, when you pick up the corrugation, pay attention to the characteristics. Usually they are contained in the instructions for the product. Characteristics include parameters such as length, type of seal, bore diameter, and much more.

The diameter of the corrugated pipe may also differ. Therefore, before purchasing it, measure the diameter of the pipe where it will be attached to the toilet. Of course, the ideal option is to buy a toilet bowl and corrugation together. Then the option with the wrong selection of the diameter of the corrugated pipe is completely excluded.

What else is used to connect the toilet to the sewer if the corrugation for one reason or another is not suitable:

1. The coupling is used if the outlet of the toilet is located in the immediate vicinity of the sewer.
2. A plastic outlet is suitable if the entrance to the sewer system is on the side and at a short distance.

A soft or hard corrugated pipe is used when the sewer hole is located just opposite the toilet, but there are any obstacles on the way. The second option is to deploy.

When choosing, you should also give preference to corrugation from a reliable manufacturer. Do not be worth saving on it, otherwise frequent repairs and replacements will haunt you. Material from which they are made a budget option corrugations, dries out too quickly and becomes brittle.

How easy is it to remove the old corrugation?

So, you have a problem when you need to remove the old corrugation and replace it with a new one. What do you need to do for this and where to start? The process of removing the old corrugation will be easier if:

1. The installed corrugated pipe is stretched as much as possible. In this case, it is quite easy to remove it from the toilet pipe and then from the sewer pipe. At the same time, the remaining water can be easily removed from the pipe by draining them into the sewer.
2. If the toilet is in a corner position, then the arc rule will have to be applied here. In this case, the corrugation can also be easily removed from both nozzles. In this case, you first need to remove it from the toilet pipe.
3. It happens that the corrugated pipe is absolutely not stretched due to the fact that the toilet is too close to the drain Wastewater... Here, for easier removal of the corrugation, you will have to remove the toilet itself from the mountings. The corrugation will be removed in the same sequence as in the previous version.

Installation rules in case of replacement of the corrugation

Now almost all plumbers prefer to work with corrugation. It is easy and quick to install it. Any problems associated with it are mainly reduced to leakage due to wear of the product. This occurs at the end of the life cycle.

If you decide to do it yourself and make a replacement yourself, then it's good if you already had some kind of plumbing experience. Then replacing the corrugation will not be difficult for you.

Installing the corrugation is usually straightforward. One end of it is inserted into the sewer pipe, and the other is pulled over the outlet by five centimeters. Do not be afraid that it will tear, even the shortest corrugation can stretch to the required minimum.

In order for the joints to not allow air or water to pass through, they must be treated with a sealant. It is necessary to process the sewer bell with it only after it is washed and before the corrugation is installed in place.

Installation process

The process of installing a corrugated pipe goes through the following points:

1. The toilet nipple is thoroughly cleaned of the remnants of the seals and connections that were in it before. Roughly the same is done with the drain pipe. It happens that old joints are sealed with concrete, then you have to knock them down with a hammer and chisel.
2. The joints are wiped dry so that no grease or dust spots remain there. It is necessary to ensure that there are no traces of sealants or other means from the previous installation on the pipes.
3. First, the corrugation is inserted into the toilet, pushed to the drain and the other end is inserted into it.
4. It is best that the corrugation is not too tight. This will increase its service life.
5. Finally, the toilet is screwed to the floor.

When do you need to install a corrugation?

When does the installation of the corrugation become an integral part of the plumbing works in your own bathroom? Corrugation is absolutely necessary in two cases:

1. The toilet is installed with an offset to either side, or at an angle to the entire bathroom. This may be necessary when the floor is raised to a certain level, or a new device is installed, such as a washing machine. Then the toilet bowl in its previous position may be inconvenient to use, and it will need to be moved or slightly displaced.
2. You accidentally purchased a toilet with a larger or smaller diameter than the corrugation itself. This often happens when they buy an imported toilet and have a straight entrance, and the sewer hole, on the contrary, is intended for oblique installation.

Thus, it will not cause us any difficulties if we know its features and worry about the right choice still in the plumbing store.

The work of replacing or installing a toilet bowl 20 years ago was accompanied by a difficult fit of its outlet to the sewer. Heavy and awkward cast iron pipes made plumbing installation inconvenient and time consuming, using the efforts of several workers. After the advent of plastic fittings, they were replaced by universal corrugated connectors. So today we will tell you how to install the corrugation on the toilet yourself.

Rules

The flexible and hygienic designs are very easy to install. However, do not forget about observing some rules when working with modern products. But, first you need to understand the design of the drain slope in the toilet, which you decided to attach to.

The outlet angle can be:

• straight;
• oblique;
• vertical.

In the first two cases, the installation of the flexible connecting sleeve is not difficult. However, with a vertical slope, its installation becomes impossible. In this case, the neck of the toilet bowl must be firmly connected to the vertical drainage system.

In the photo - plastic corrugated sanitary sleeve

If a higher connection level is installed, it will not be possible to establish a free drainage of the liquid. Therefore, today we will not consider an independent connection. vertical release... In other cases, it can be produced even without the necessary qualifications and training.

When to change the corrugation

Most often this happens in two cases:

Advice: when repairs in a house or apartment include replacing the sewage system, it is better to immediately remove the pipes for a certain type of toilet bowl release.

What are the disadvantages of corrugation

1. A thin wall that is easily damaged from the outside and from the inside, for example, by accidentally flushing a shard of glass down the toilet... With all its resistance to an aggressive environment, any plastic has a tensile strength and therefore gradually deteriorates under their influence. The thinner the wall is, the faster this will happen.
2. Bathroom aesthetics... The corrugated plastic sleeve looks, however, not as neat and beautiful as the pipe that fits the toilet bowl release. Deposits inside can also be seen through its walls.
3. Inevitable sagging of the corrugation when the distance from the toilet outlet to the sewer socket is large. Due to the unevenness of the walls, deposits will remain, which will definitely pull it down. After that, water will begin to accumulate in the place of sagging.

How to choose quality products

Understanding the principle of corrugation selection, you will be able to purchase the best product for work:

1. A wide range of prices should not confuse the consumer when choosing the right plumbing items. Also, when choosing a corrugation, you need to pay attention to the highest quality product.
2. The price of such connecting plastic products is low. Therefore, with insignificant savings, the consumer risks buying a product of not very high quality, which will subsequently complicate the operation of the plumbing fixture and reduce its service life.

Advice: alas, so far our companies cannot compare in quality with foreign ones, so we recommend purchasing imported products.

1. When choosing, also give preference to corrugation reinforced with metal wire or mesh. Such a product will be able to maintain its original strength longer.

1. Determine in advance the distance from the outlet of the toilet to the bell of the sewer system, then the elastic partition will not sag or stretch excessively.
2. Choose products with thick and hard walls, then they will perform their function longer.
3. The durability of the product is also influenced by the thickness and stiffness of the pipe walls.

Installation of plastic corrugation

The following is suggested step-by-step instruction with recommendations that will help you carry out repairs with your own hands:

1. Disconnect the toilet tank from the water supply if the installation will be carried out on the plumbing already installed in the bathroom.
2. Thoroughly clean the outlet of old sealant, cement paste, mucus and dirt.

Tip: Strongly cured cement can be easily beaten off with a chisel. Do not leave even the slightest layers, as this will negatively affect the tightness.

1. Apply a coat of sealant to the outside of the outlet. When you put on the pipe, it tightly wraps around the neck of the plumbing fixture and the silicone will hide inside the connection.
2. Put the corrugation on the outlet with the wide end, over the edge, stepping over at least 50 mm. Spread it out in a circular motion, then you can avoid distortions between the inner membrane and the wall accordion.

Tip: if the corrugation is too tight, it can be difficult to install. Then use the force of pressure.

1. Wait for the sealant to dry.
2. Install the toilet in a permanent place, carefully adjust the location of the components. Fix it with the fixing screws.
3. Insert the seal all the way into the drain hole. Apply to it interior sealant.
4. Check the tightness of the structure by pouring 10-12 liters of water into the toilet. The outer part of the corrugation must remain dry.

With the development of plumbing technologies, all the details of our daily life will become simpler, lighter, and better quality. 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 or corrugation caused a negative, since it was necessary to disassemble half of the sanitary unit in order to perform such, at first glance, a simple operation. Now it is much easier to do this, thanks to the appearance of the corrugation for the toilet.

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

On one side of the corrugation is a branch pipe, which is designed to be connected to the outlet of the toilet bowl, and the other end of the corrugation is designed to dock with the sewer pipe and has the shape of a ring with a herringbone sealing rubber.

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, the most the best option purchase of corrugations will be a simultaneous purchase with the toilet.

Then the option is excluded that you will buy the 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 the sewer pipe;
• - plastic bend or branch pipe with cuffs. It is installed 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 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. There is no need to save money by buying corrugation from a dubious manufacturer.

As practice shows, after a while, cheap corrugations often fail, the material from which they are made quickly dries up and loses strength.

Exists 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 nipple, and then from the sewer pipe nipple. 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 itself from the mountings.

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

Connecting a sewer pipe to a toilet flare seems straightforward, but there are some relative complications in the 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 (washing machine) has been added, and without displacement, the toilet will be inconvenient to operate;
• .- if the owners, by mistake, purchased a toilet with a smaller or large diameter rather than corrugation. Such a situation can arise when they buy an imported toilet bowl with a direct outlet, and the sewage system in the apartment is brought out for an oblique installation.

The process of installing the corrugation goes through the following points:

• - it is necessary to thoroughly clean the toilet socket from the remnants of old connections and sealing rubber. The same operation should be done with the drain of the sewer pipe. If cement mortars were used to seal the old corrugation, they can be easily knocked down with a chisel and hammer;
• - then you need to wipe dry the toilet and drain pipe with a dry cloth 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 drain pipe and shove the corrugation into it;
• - the less the corrugation is stretched, the longer it will last;
• - after all the operations done, we fasten the toilet to the floor.

Until recently, work related to the installation of the toilet was accompanied by a difficult fit of its outlet fitting to the bell of the sewer system. This was due to the use of heavy cast iron pipes, which made installing plumbing an inconvenient and hours-long process. With the advent of plastic components, metal parts were replaced by elastic corrugated connectors. Meanwhile, you need to know how to install the corrugation on the toilet using a minimum of tools.

What is corrugation and how can it be installed on the toilet

The Corrugated Universal Connector is a flexible, folded adapter that connects the toilet bowl outlet to the drain pipe. The inner diameter of the corrugation is 75 mm, and its length can vary from 231 to 500 mm, depending on the distance between the plumbing and the drain pipe. One end of the corrugated connector is put on the outlet of the toilet bowl, and its other end is inserted into the socket of the drain system.

When to use corrugation

In most cases, a corrugated connector is used when installing a toilet, when the sanitary ware is displaced in relation to the bell of the sewage system. This usually happens when installing new plumbing. In this case, the release of the toilet bowl may not fit the old design of the flush system. The need for corrugation may also arise after carrying out. For example, when the floor level was raised, there was an axial displacement of the toilet bowl drain and the sewer inlet socket.

How to choose a corrugated connector

When choosing a corrugation, you need to give preference to a product that is equipped with a reinforcing wire or a metal mesh. This will provide a longer service life and allow the connector to remain intact for longer.

When choosing such a product, you should determine in advance the actual distance from the plumbing outlet to the sewer system branch pipe. Correspondence of the corrugation length to this parameter will prevent its excessive stretching or sagging.

Today, there is a fairly wide selection of such corrugated joints on the sanitary ware market. Meanwhile, the quality of such products can vary significantly, depending on the manufacturer. When choosing a corrugation, you need to pay attention to the density of the elastic material, the uniformity of the cuff, as well as the integrity of the outer O-rings.

Installation of corrugation

During the renovation works in the bathroom, in most cases, new plumbing products are purchased. The toilet bowl is no exception, the replacement of which is accompanied by the correct installation of the corrugated connector with the sewer system. Meanwhile, such plumbing products have differences, depending on design features... For example, the toilet can be equipped with a straight, oblique or vertical outlet. This, in turn, will determine the length of the corrugation.

The process of replacing the corrugated connector on the toilet can be broken down into several technical steps. In this case, a certain sequence must be observed. Corrugation installation involves the following working stages:

• studying the design of the toilet in order to determine the length of the corrugation;
• purchase of a connector;
• treatment with a sealing compound of the surface of the drain pipe on the toilet and the membrane on the corrugation;
• installation of the connector;
• additional processing of joints with sealant;
• tightness check.

There are two main options that involve connecting the toilet to the sewer system. In the first case, it is necessary to install a new plumbing product. The second option implies correct installation corrugated connector on already installed toilet... The difference between the two is only in the preparatory work before installing the corrugation.

The main stages of installation of a corrugated connector

In practice, the connection of the toilet to the sewer system must be carried out in a certain sequence.

1. Preparatory work. When installing a new toilet, there is no need to specially prepare it for connection. If an elastic connector is installed on an old sanitary product, its outlet should be cleaned from traces of the previous sealing compound or cement solution. The fact is that any solid layers will impede the tightness of such a connection. Any metal tool can be used to clean the ceramic drain that will make this process effective.
2. Cleaning surfaces. After cleaning the ceramic surface of the outlet, you should get rid of any traces of clogging on the inlet of the sewer system. If such a structural element is made of cast iron, then it must be cleaned carefully, without hitting it with heavy objects. Otherwise, destruction of such material can be caused. The same precautions should be applied in the case of a plastic bell.
3. Sealing. Apply a sealing compound to the cleaned or new surface of the toilet outlet pipe, evenly distributing it around the entire circumference. After that, a corrugation should be put on it with the edge where the inner elastic membrane is located. In this case, the cuffs of the corrugated connector should overlap the outlet edge by about 5–6 cm. In this process, it is necessary to ensure the uniformity of the nozzle, excluding distortions.
4. Toilet bowl installation and corrugation replacement. After that, you need to wait a little so that the sealant dries. Now you can start installing the toilet in the intended place, which was determined during the preliminary fitting. Having installed a plumbing product, you need to connect its outlet to the bell of the sewer system. To do this, firmly insert the edge of the corrugation, which has an external seal, into the cleaned hole of the drain outlet. This connection can be sealed with a sealant if necessary.
5. Checking the tightness of the connection. Having installed such a connecting element, you need to make visual inspection the entire system for visible distortions or insufficient tightness. If necessary, all malfunctions should be eliminated, and the existing gaps and loose fit should be filled with a sealing compound. You also need to inspect the corrugation itself in order to make sure that it is not twisted or kinked.
6. Checking the operation of the exhaust system. After completing all major work, you should check the system performance. To do this, you need to connect the toilet tank to the water supply. After filling the drain tank with water, a test flush must be performed. In this case, you should carefully inspect all connections, making sure they are tight. If problems are found, you need to take measures to eliminate them.

In general, replacing the corrugated connector on the toilet is not difficult and does not require special tools and equipment. Meanwhile, performing such work, you should follow all the rules for installing the corrugation and a certain sequence of technical operations.

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

What is a toilet corrugation and why is it needed?

Corrugation is just a plastic bend, which differs from all 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).

This miracle of modern civilization is used not only for toilets, but also for baths, sinks and washbasins, while the difference lies only in the diameter.

Such a branch connects the outlet of the toilet bowl to the sewer pipe. And it doesn't matter them mutual arrangement... The main thing is that the sewage system is below the toilet drain hole, otherwise the water simply will not flow

High-quality corrugation is a guarantee of system safety

The choice of high-quality corrugation is also of great importance. As you know, the range of goods in hardware stores, as they say, for every taste and wallet. In our case, you need to focus only on quality. A corrugation for connecting a toilet is not so expensive as to significantly save money, and there can be a lot of problems with a leaking drain and outraged 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 wires. The latter is definitely better. They flow less often, do not sag and last longer.

When two plumbing items are side by side, it is more convenient to use one corrugation with a branch

In small bathrooms where you need to install at the same time a large number of plumbers, and even place washing machine, sometimes there is simply not enough space on the sewer pipe for such a number of bends. Then a corrugation for a toilet bowl with a branch is used. It will be a salvation if the sink or bathtub is located in the immediate vicinity of the toilet.

When purchasing a corrugation, do not forget to buy also a can of plumbing sealant. Many manufacturers claim that it is possible to do without it, but "God protects those who are careful."

"The work of the master is afraid" - we proceed to the installation

The first stage of installation of the corrugation is best done before installing the toilet in its permanent place - it is more convenient this way. If the plumbing is new, there is no need to prepare it for connection. If you are changing the drain on an old toilet, clean its outlet from the remnants of the old sealant or cement mortar- any layering can adversely affect the leakage of the connection.

Now we apply to issue with outside some sealant and put on that edge of the corrugation where the inner membrane is located. The outlet should cover the edge of the outlet by 5-6 cm. Make sure that there are no distortions. The corrugation should be worn straight.

Let the sealant dry and reinstall the toilet. 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 not necessary to seal this joint at all, but this procedure cannot damage either.

That's all, it remains only to check if everything turned out as it should. To do this, you can wait until the tank is connected to the water supply and drain the water from it several times, or you can use a bucket - just pour about 10 liters of liquid into the toilet at a time. If it does not flow, everything is in order, you can use it.

When the toilet is located far from the wall, it is important to choose the correct length of the corrugation. It stretches, of course, but everything has its limit, and if you stretch the pipe too much, its walls will become thinner and their strength will be greatly reduced.

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

Do not allow the corrugation to sag in the middle. This can lead to the accumulation of fecal matter at the lowest point and, as a result, to blockage. If the release of the toilet and sewage pipe are located high enough, you need to arrange a support for the corrugation from scrap materials.

V Lately it is customary to close communications with protective screens or boxes with a door, and use the fenced-off space as a storage for various little 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 paint can, it can bend, and then burst. Conclusion: don't bet on corrugated pipe heavy objects, it could leak.
