After purchasing the bath and installing it in the appropriate room, it is necessary to carry out operations to connect to the sewer communications.

This task is simple, however, in order for everything to be as effective as possible, you must adhere to a few simple rules about which will be discussed in this article from the site

• to carry out this operation, you will have to acquire a special siphon, which has openings for overflow and drainage. It is recommended not to use flexible corrugated pipes, as they have many disadvantages, such as quick dirtiness and high resistance to water;
• the most suitable option is a flexible or rigid plastic pipe;
• before connecting the bath to the sewer, you will need to clearly equip the height difference in the area of ​​the drain and the connection point. The height of the siphon outlet must be precisely matched, which will allow the water to descend much faster. If you do not pay attention to the height difference, then the water will stagnate in the bathroom bowl;
• access to the siphon must be free, since it will have to be repeatedly cleaned from contamination in the future;

We connect the bath to the sewer

If the sewerage system is assembled from plastic pipes, the siphon is connected using a special smooth pipe with a diameter of 40 mm. You can use a cut plastic pipe with the same diameter. In the case when the pipeline is 50mm, you will have to use an adapter from 40mm to 50mm.

If the sewer pipe is made of cast iron, then it is necessary to use a special coupling made of 73-40 rubber. The rest of the operations are similar to plastic pipes.

• first, the siphon is assembled according to the instructions that are attached to the product;
• do not overlook the sealing gaskets, otherwise there is a possibility of stink in the bathroom;
• install a siphon;
• if it is necessary to tighten plastic elements, it is necessary to do this exclusively by hand, without the use of technology, since it can ruin the thread or fastener;
• after installation, a pipe is connected to the device at one end, while the other is diverted to the sewer pipe and connected;
• during installation, it is necessary to clearly monitor the tightness and tightness of the joints. If a problem has arisen, it is necessary to fix it immediately, otherwise in the future this will require more effort;
• in the case when the bath is installed close to the wall, the joints are tightly sealed with a sealant, otherwise the water will get under the bath.

What to do if unpleasant odors start to appear in the bath

In the case when an unpleasant odor arises in the bath, this situation is not happy, but on the contrary, it is upsetting. Next, we will consider why this happens and how to get rid of it.

One of the reasons is improper installation of the sewage system. It is necessary to check for the presence of a water lock under the bathroom, sink and on the siphons, because it is he who cuts off all unpleasant odors. In the case when a water seal is installed in the toilet, but odors are still present, you need to make sure that the siphons are installed correctly.

If, instead of siphons, corrugated tubes are installed, then they must be replaced, since water plugs do not form in them. If this is not possible, then it is required to bend the tubes so that water collects in them, which forms a water lock.

The water plug may also be absent due to the breakdown of the siphon, which can be guessed by the characteristic loud squelching sounds. The most common reason for the failure of a siphon is its large pipe, due to which the water pressure drops noticeably. If this is the reason, the siphon is replaced.

Also, a water plug may be absent due to the fact that ventilation is disturbed in the sewer, or the diameter of the riser is too small. In this case, airing is formed in the pipe. It is rather difficult to do such work on your own, therefore it is easier to invite a specialist.

Water also evaporates in the chimney if the room has not been used for a long time. In this case, machine oil poured into the hydraulic lock will help.

If all operations have been done, but the smell has not been eliminated, it is necessary to check the presence of a ventilation pipe. Such a pipe is connected to the riser on the upper floors and is led out to the roof. It acts as a hood and gets rid of all unpleasant odors.

If this is not the reason, pay attention to the inspection hatches, namely, their tightness.

It happens that during installation, the rubber band falls off the hatch, which is why it does not fit tightly to the pipe and allows odors to pass through.

The same problem can arise due to mechanical damage to the sewer pipe.

The last possible reason for the smell in the bathroom is a clogged sewer, which needs to be cleaned from time to time.

If you did not manage to get rid of the odors on your own, then the last option remains - the invitation of a qualified specialist who will find and eliminate the cause.

When carrying out repairs in the bathroom and replacing old plumbing with a new product, it is necessary not only to purchase it, but also to connect the bathtub to the sewer with your own hands, installing it in the place intended for it. It is not difficult to do this kind of work, since it does not require special skills.

The home craftsman needs to know how to properly connect the bathtub to the sewer. To do this, he needs to follow the installation instructions and deal with the nuances of the repair (read also: "How to start repairs in the bathroom - the secrets of the correct planning of bathroom repairs").

Pipes for connecting the bathtub to the sewer

According to experts:

• before connecting the bathtub to the sewage system, you should buy a special siphon, which is equipped with devices that ensure the tight connection of plumbing fixtures directly to the drain (read: "Which siphon for the bathtub is better to choose - types, design features");
• installation of the sewage system in the bathroom using corrugated pipes (shown in the photo) is allowed only as a last resort, since such a connection cannot be called ideal for a number of reasons. The fact is that folds on the pipes contribute to the accumulation of debris and it is almost impossible to clean them, and besides this, during operation, they contribute to an increase in hydraulic resistance;
• the connection of the bathtub to the sewer is considered correct when the siphon outlet is mounted above the sewer pipe. The difference in height should facilitate a quick and unimpeded drainage of waste water. Violation of the rules governing how to connect the bath to the sewer will lead to the waste water stagnating and a blockage;
• the drainage system must be periodically cleaned. To provide access to the siphon, an inspection hatch is purchased and placed on a protective screen.

When a sewage system is created in a bathroom, pipes for supplying it to plumbing are chosen according to the following principles:

• for the installation of the system, preference should be given to rigid plastic pipes, even if it is necessary to use knee elements;
• if the sewer system in the bathroom has a complex structure and it is problematic to dock it with the siphon outlet, use a corrugation.

Pipes for connecting the siphon to the sewer are made of rigid or smooth flexible plastic (product diameter 40 millimeters). When the sewage system in the bathroom with your own hands is made using 50 mm diameter pipes, you will need to use a 50/40 mm rubber adapter. If the sewer system in the bathroom is laid from cast-iron elements, then an adapter of 73/40 millimeters will need to be installed.

The procedure for connecting the bathroom to the sewer

The process of how to connect a bathtub to the sewage system consists of several stages:

1. First of all, they carefully study the instructions that manufacturers attach to their products, in this case, to the siphon. Assemble the product according to the manufacturer's recommendations. All supplied gaskets must be put in place.
2. The plastic parts of the siphon (see photo) are collected by hand. Gas and open-end wrenches must not be used, as plastic threads must be handled with care (read also: "").
3. After the siphon is assembled, the corresponding end of the product is placed in the sewer pipe, and its other end is connected to the drain hole of the plumbing fixture, not forgetting to use the sealing gaskets. An overflow pipe is also connected to the bathroom.
4. Do-it-yourself installation of the sewage system in the bathroom is performed in such a way that all joints are sealed. Silicone is not capable of replacing special gaskets; it can only additionally process the joints of individual elements.

How to connect a bathtub to the water supply network with your own hands

When the problem of how to collect the sewer in the bathroom is solved, and the plumbing is connected to the sewer system, they begin to check the tightness of the connections and the quality of the wastewater drainage arrangement. For this, plumbing fixtures are connected to the water supply network.

The connection process is as follows:

1. On pipes supplying cold and hot water, a shut-off valve is installed in front of the connecting fittings, so that later you can carry out repairs or change the mixer.
2. Eccentrics are connected to the fittings. In order to ensure the tightness of the joints, tow with paint or fum tape is used. Eccentrics are needed for the correct joining of the pipes of the water supply network with the connecting nuts.
3. To hide the unpresentable look of eccentrics, decorative attachments are used.
4. Rubber gaskets are inserted into the connecting nuts, which will ensure the tightness of the pipeline (in this case, fum tape is not used).
5. Then the mixer is screwed on, while it is necessary to tighten both nuts so that there is no distortion. Place a rag under the wrench so as not to scratch the chrome-plated surface. Excessive efforts should be avoided.
6. After completing the connection, the system is checked for leaks by opening both taps and checking for leaks. Even after the water is shut off, it is necessary to continue to observe the joints of the pipes with the plumbing, since leaks may occur under pressure.
7. If a leak is found, the leaking assembly must be redone. The most common cause of a malfunction is an incorrectly installed or poor-quality gasket.

According to professionals, reinforced hoses should not be chosen for plumbing, since they are very unreliable. A more acceptable option is corrugated pipes made of stainless steel.

Knowing how to make a sewer in the bathroom and connect the water supply to the plumbing on your own will help the home craftsman to do this job correctly. If you are unsure of your own skills, it is better to turn to experienced specialists.

Connecting the bath to the sewer on your own

Many of us believe that the most difficult process is installing the purchased bath. But in fact, the main difficulties are caused by connecting the bath to the sewage system, since the safety of the room from leaks depends on the quality of the work.

Indeed, a dripping faucet will not do as much harm as a leaking siphon under a bathtub or a fistula in a sewer riser. And the situation when the bathroom smells like sewage is especially troublesome. Let's deal with these and other problems together.

Operating principle

First, let's look at how the sewage system works in the bathroom:

• The bathtub, which is filled to the brim, discharges part of the water through the drain-overflow system;
• When you open the drain hole, water from the bath enters the siphon;
• Bypassing the water seal, the wastewater passes through the sewer pipe (hose) connected to the tee;
• Through the sewer tee, the drains enter the riser.

Past materials

A couple of decades ago, when there was no flourishing of PVC products, all sewage was collected from cast iron. In particular:

• Siphons and inlet pipes;
• Washbasin knee;
• Tee of an apartment sewer pipe;
• Inspection window on the riser;
• The riser itself is in the apartment.

And for the tightness of the connection, in addition to the traditional tow, they used:

• Cement mortar;
• Liquid glass
• Epoxy adhesive
• Rubber, etc.

Modern materials

But with the advent of the plastic era, everything has changed. Today, almost any adult man can assemble and connect a sewer siphon.

What is the risk of incorrect installation and connection

The bathroom smells like sewage - why is this happening? Residents of apartments in which they recently changed their bath or washbasin often turn to plumbers with such a question. And the answer is simple - errors in the installation of the siphon.

If the bathroom stinks, it only means one thing:

• Either the hydraulic valve is not doing its job;
• Or there is a leaky connection between the siphon and the intake tee, through which sewer odors penetrate into the room.

According to experienced plumbers, it often stinks in the bathroom due to the decrease in the radius of the drain pipe from the corrugated hose from which the siphon is formed.

For reference: The volume of water contained in it is not enough to withstand the atmospheric pressure of the general house sewage system. And it "pushes" the water plug, and unpleasant odors penetrate into the room.

The main stages of work

Let's consider in detail how the installation of the sewage system in the bathroom is carried out:

• Preparation of communications for connection;
• Installation of plumbing fixtures;
• Siphon installation;
• Connection of nodes into a single network.

Difficulties can lie in wait for homeowners at each of the designated stages. For example, a tubular siphon made of brass or chrome means an open installation under the washbasin. But the drain pipe is designed for horizontal installation, which means that at the stage of repair it should be transferred to the wall under the washbasin.

Connecting a shower tray is also associated with certain difficulties:

• Small size of the siphon;
• Cramped conditions for installation;
• Almost always horizontal drain;
• Lack of preventive disassembly.

Bath connection process

Most often, new baths are purchased with a set consisting of:

• Siphon and connecting pipes;
• Drain-overflow systems.

In most cases, this is a single unit, which has its own installation features:

• On acrylic baths, thanks to the preliminary assembly of the power frame, the siphon is installed immediately (on an inverted bath);
• The siphon is connected to cast iron and steel baths after their installation

For reference: Installation of steel bathtubs on a brick base narrows the space for work. Therefore, experienced plumbers pre-install individual units on the bathtub.

Tip: Your main task is to make all connections tight. When installing a bottle siphon, special gaskets are always included in the kit, which must be used.

We arm ourselves with the assembly diagram and proceed:

• First, we install a drain-overflow on the bathtub, because after installing it close to the wall, it will be problematic to do this;
• After installing the bath in place and fixing, we assemble the receiving unit (a bell with a branch pipe and a protective mesh). We put on a gasket on the edge of the socket, insert it into the drain hole of the bath and from below, also with a gasket and a nut, connect the parts into a single unit. Depending on the design, the mesh can either be screwed on or removable;
• The turn of the siphon assembly has come. We assemble the glass according to the attached diagram and attach it to the protruding branch pipe of the receiving unit. We fix it with a plastic nut, tightening it by hand;
• Do not forget to connect the drain hose of the overflow drain system - we put its end on a special branch;
• From the siphon into the sewer tee, we insert a corrugated pipe or a plastic one using rubber adapters.

Tip: the adapters act as a seal that allows you to reliably seal the entire structure.

Conclusions: we are sure that now you know almost everything about the sewage system and the method of connecting the bathtub. It remains only to apply the knowledge gained in practice, and to spend the money saved at work on the purchase of stylish accessories for the bathroom.

After the bath was delivered to the place where it is planned to be installed, the turn of a very important stage comes - connecting the bath to the sewer. Connecting to utilities is not considered very difficult, so you can do them yourself. The instructions presented in our article will help to understand the intricacies of self-installation.

PREPARATION FOR INSTALLATION

Location and materials

During installation, it is necessary to take into account a number of important points:

1. It is recommended to connect the bathtub to the sewer pipeline using a bath siphon - a special device that has assemblies that provide a connection to the drain hole and the overflow hole.

1. If the installation is carried out independently, then it is not recommended to use corrugated tubes, since they have a number of disadvantages:

• they have high hydraulic resistance;
• they quickly accumulate pollution;
• such tubes are difficult to clean.

1. Before connecting the bathtub to the sewage system, it is necessary to ensure that the height difference between the drain pipe and the connection point is correctly equipped. In this case, special attention should be paid to the height of the siphon outlet to ensure a better drainage of drainage water from the bath.

Pro tip: If the height difference is not fulfilled or it is insufficient, then this will lead to stagnation of water in the bath.

1. It is necessary to provide free access to the siphon so that it is convenient to dismantle it if it is necessary to clean its inner surface from contamination.

Choice of pipes

You can use either rigid or smooth flexible plastic pipe, while being guided by the following rule:

• if it is possible to connect the bathtub to the sewage system using a rigid pipe, for example, a pipe consisting of 2 elbows with the necessary turns, then it is better to use this option;

• if the connection of rigid pipes is difficult, then a corrugation should be used.

Selection of pipes for connection to the sewage system:

• If the sewage system is mounted from plastic pipes, then the siphon is connected using a special smooth flexible tube with a diameter of 40 mm, or a conventional rigid plastic pipe with the same diameter is used for this purpose.
• In the event that the diameter of the sewer pipeline is 50 mm, then you must additionally use an adapter that allows you to make the transition from 40 to 50 mm.
• If cast iron pipes were used for the sewer system, then before connecting the bath to the sewer, you need to purchase a 73/40 rubber sleeve for connection.

BATH CONNECTION TECHNOLOGY

The procedure for connecting the bath to the sewer system

The connection procedure is as follows:

1. The siphon is assembled in accordance with the instructions attached to it, paying special attention to all the necessary sealing gaskets.
2. The plastic fasteners are tightened by hand, acting very carefully. The tools are not used, since when using them, the part can be broken.
3. After the device has been mounted, one end of the pipe is attached to it, and its other end is brought to the drain hole of the sewer and the connection is made.
4. The connection of the bath drain must be accompanied by careful control over the density of the assembled joints in order to ensure a high degree of their tightness.

Pro tip: If the slightest malfunctions are found, they must be eliminated immediately, otherwise, during operation, it will be necessary to replace the defective elements of the system.

1. When the sides of the bath are tightly attached to the walls, the joints must be carefully sealed so that water does not have the opportunity to penetrate under the bath.

Connecting the bath to the water supply

As well as connecting the bathtub with your own hands to the sewer, it is also possible to independently connect to the water supply and install a mixer. You don't have to call a plumber to do this.

Consider this technology:

1. A shut-off valve is installed on the pipe in front of the fittings, the presence of which is necessary to shut off the water when replacing the mixer or in case of repair.
2. Eccentrics are attached to the fittings on the mixer (first by hand, and then reinforced with a key). In this case, an FUM tape or a specialized thread is used, intended for connecting elements of the water supply system.
3. Decorative attachments are put on the eccentrics.
4. On the mixer, rubber or silicone gaskets are inserted inside the thread, and then the mixer is screwed to the eccentrics (you do not need to use FUM tape or thread in this case).

Pro tip: The bath connection diagram must include a check of the quality of the work performed - if leaks are detected in the mixer, the gasket is replaced - it is possible that the leak has arisen due to a defective gasket.

1. The mixer is screwed on at the same time from 2 sides. In this case, uniform sealing of the gaskets occurs.
2. If the bathtub comes with a mixer when purchasing:

• then the permissible level of the height of the pipes is below the level of the bathtub, since in this case the connection is carried out using reinforced hoses;
• at the same time, it is not necessary to align the ends of the pipes - such hoses are very plastic;
• the basic rule in such a situation is to make sure that the length of the reinforced hose is slightly longer than the distance from the bathtub to the end of the pipe.

After all the operations on connecting the bath to the water supply and sewerage system, they turn on the water and observe for leaks. If there are leaks, then you need to make sure how well the gaskets are fixed, and also make sure the quality of the gaskets themselves (if they are of poor quality, then you will have to replace them).

The implementation of such simple rules will allow you to efficiently connect the bathroom to the sewer and correctly install the mixer. With this approach, the bathtub will last for many years!

You decided to change the bath, even dismantled the old plumbing and purchased a new one. They put the bowl in its proper place, and, it would seem, there was nothing left to do. But you do not know how to connect the bathtub to the sewer. What to do? Is it possible to call a plumber, wait for him for a long time, endure his presence in the apartment and pay for such a simple procedure? It is not so difficult for an ordinary person to call a plumbing guru to carry it out. All work can be done by hand. The main thing is to have at least some idea of ​​how to connect the bathtub to the sewer.

Connecting a bathtub to the sewer with your own hands: the necessary tools and equipment

Connecting the bathtub to the sewer with your own hands is done using a siphon - a special device with a flask or a curved pipe through which the drains freely pass into the sewer pipe. Organization of drainage without this equipment threatens you with unpleasant and constant odors from the sewer. Therefore, if you do not want to "aromatize" the living space with the drains of the whole house, install a siphon under the bathtub. But how to connect the bathtub to the sewer using this device? First, you need to decide on the type of siphon. There are several types of this sanitary device on sale, the choice of one or another depends on the model of your bath. If in doubt about the correctness of your choice, consult your dealer. But that's not all. The design of the siphon is collapsible; instructions are attached to each product. Strictly follow its recommendations and do not forget to put sealing gaskets in the right places.

Photo 2. Correct connection of the bathtub to the sewerage system will help keep the bathroom clean and tidy.

The siphon is ready, what do you need to install it to the bathroom?

The connection of the bathtub to the sewage system is carried out by connecting the siphon to the drain pipe. It is not included in the package, so you need to buy it as well. On sale you will find rigid and corrugated models. If you do not want to return to this question for several years, choose rigid models. Since the corrugated ones quickly clog up, and cleaning them is a thankless and very difficult task.

But if it is not possible to attach a rigid pipe due to the inaccessibility of the place, then corrugation is the only choice. The diameter of both models is the same and is 40 mm. The diameter of the drain in the bathroom can also be 40 mm or more - 50 mm. If you have the latter option, then you need to install the adapter.

How to connect a bathtub to a sewer: connecting a drain

When installing a siphon, try to make sure that you always have free access to it. After all, you will have to dismantle it more than once during the operation of the bath. This is necessary to clean it from dirt. If the siphon is not periodically cleaned, over time the drainage rate will slow down, or even stop altogether.

Photo 4. Bathroom siphons come in different shapes.

So, how to connect a siphon to a bathtub and a sewer drain:

• Attach the siphon to the bath, do not forget to lay the gasket at the joint, and only then start tightening the fasteners. Tighten gently without using too much force. Since the fasteners are easy to damage and spoil. This procedure should only be carried out manually, without the use of any tools. This way you will be able to control the degree of tension created, and immediately stop as soon as it has reached its limit. To seal the joint, a gasket is installed, which can be either ordinary rubber or silicone.
• Attach a rigid drain pipe on the other side of the siphon, lead it to the sewer outlet and connect to it by a simple entry. If the pipe diameters are different, install the plastic adapter first.
• Test the system for leaks. First, check the tightness of fit of all parts, if necessary, correct the situation in advance, so that later you do not have to dismantle the system and install it anew. For reliability, even at the stage of assembling the structure, it is recommended to coat each joint with a sealant.
• Test the system for leaks while using the bath. To do this, pour about half of the water into the bowl. Check the tightness and tightness of the connection of the siphon to the bath. If all is well, refill the bowl with water and open the drain plug. Take a napkin and check all the joints. Visually, you may not notice small leaks, and a damp spot will definitely remain on the napkin. If it is not there, then the connection of the bathtub to the sewage system with your own hands was successful and efficient.

What to do if unpleasant odors suddenly appear in the bathroom?

At the first stage of using the bath, you may not notice some installation flaws. They will manifest themselves literally in a few days as a persistent and unpleasant sewer aroma in the room.

Photo 5. Scheme of the correct connection of the bathtub to the sewerage system.

The reason for its appearance may be the malfunctioning of the siphon. This happens, a corrugated tube without bending is used to create a water seal. Or the angle of inclination of the installation of the system is not observed.

In the first case, it is not necessary to change the siphon, it is just necessary to make a bend on the corrugated tube to create a water plug and fix it in an accessible way. In the second case: check if there is a slope in the drainage system, if not, then correct it to an angle of 5 degrees.

One of the options for the appearance of unpleasant odors in the bathroom can be an obstruction of the sewage system. That is, if it simply clogged, and an impassable blockage appeared in it. Clean it with any available means. If you are unable to get rid of the stench on your own, contact a professional plumber to relieve you of this unpleasant problem.
