After choosing and purchasing a sink or washbasin, the most important steps are installation, connection to the water supply and sewerage system. In many ways, the nuances of installation depend on the type of plumbing fixture. Sinks can be of different types - overhead, console (hanging), mortise. This determines the choice of siphon, specifics, and ease of connecting the washbasin and sink to the sewer.

Installation of a sink in the kitchen and a washbasin in the bathroom is carried out approximately the same way, because the purpose of the devices is similar. Most often, the home owner can do all the work himself. There are general rules that must be followed when installing plumbing; you should definitely know them. However, if you do not have the skills to handle tools or are planning a complex plumbing installation, it is better to call a specialist.

Installing a sink in the bathroom

General scheme of work for installing a sink

1. Preparatory work. At this stage, the places where the sink is fixed to the wall are marked, the fasteners are screwed in and the specifics of mounting the support, if provided, are determined.
2. Connection to water supply. This work can be done when the sink is already firmly attached to the wall, but it is better to install the faucet in advance.
3. Securing a plumbing fixture. At this stage, you need to securely fix the sink on fasteners and supports, and finish connecting to the water supply.
4. Connecting the sink to the sewer. This is the final stage of work. It is necessary to properly install plumbing equipment and ensure tight connections. The ease of use and the presence/absence of blockages in the future depend on the correct connection of the washbasin to the sewer.

Stage #1: preparing fastenings for the sink

If a simple model without additional accessories is chosen, and a washing machine or other device is not installed below, then the optimal height of the sink is 850 mm. The plumbing fixture will be convenient to use, and you can do the installation of the siphon and connect the sink to the sewer yourself, because there will be enough space, and access to all elements of the system will remain free.

For a model with a support, the height is determined depending on the height of the leg or furniture in which it will be mounted. When it is decided where the sink will be installed, draw a straight horizontal line on the wall. The device is applied to the line, the attachment points are marked. This is difficult to do alone, so you need an assistant to hold the sink. If the plumbing fixtures are installed on a leg or piece of furniture, the task is simplified.

Using the finished markings, holes are made in the walls, dowels are hammered in and studs are installed for fastening. The depth of screwing in the studs should be such that the device is securely fixed, but at the same time freely placed on the mounts. As a rule, all the necessary parts are included in the sink kit. When installing, you need to use all of them so that there are no unnecessary parts left.

Height of sink above washing machine

If you plan to place a washing machine under the sink, then a “water lily” type model is best suited. Its drain is equipped so that there is enough space under the sink. There are two types of drain: the first is directed backwards, and the second is directed downward.

Designs of the first type leave more space for the machine, however, due to the bends, frequent blockages are possible. The downward drain is designed to allow water to flow through the pipes normally, but the sink will have to be placed higher above the machine. The height of the plumbing fixture is calculated individually.

To make the sink more convenient to use, it can be moved slightly forward from the wall. Then, when washing, a person will not rest his feet on the machine. This simple technique will allow you to save as much usable space as possible without compromising the comfort of use.

Stage #2: connecting to the water supply

To install the faucet, insert a mounting pin into it, then connect the water hoses and carefully tighten them so that they are secured tightly, but not excessively. Next, install the sealing rubber, washer, and nuts (they are tightened with a wrench).

The main thing is that after installation the mixer is positioned correctly: its spout should be placed at right angles to the wall on which the sink is mounted. You should also pay attention to the tightening of the nuts. Once the mixer is already secured, it will no longer be possible to tighten them more tightly, so you need to immediately do everything efficiently and check it.

Stage #3: attaching the washbasin to the wall

When the mixer is already installed on the sink, you need to attach it to the wall and complete the connection to the water supply. To do this, place the device on the prepared mounting studs, install the plastic inserts that are supplied in the kit, and tighten the nuts. If there is a support under the sink, then place it on it.

There should be a rubber seal under the tap. It is placed above the nut. The seal will not prevent you from tightening the nut in the future, so do not tighten it too tightly. If the tap leaks when checking the connection, simply tighten the connection tighter.

Stage #4: connecting the sink to the sewer

How to connect a washbasin to the sewer? This stage is final. A siphon is connected to the plumbing fixture, to which a pipe is attached - corrugated or rigid with a bend. Then the pipe is connected to the sewer. If its diameter does not coincide with the sewer outlet, use a special rubber adapter.

When the work is finished, all that remains is to check the tightness of the connections. To do this, open the taps and run them through the pipes with a dry hand or a white napkin. If everything is normal and there are no leaks, the plumbing is ready for use.

Connecting the sink siphon to the sewer

Choosing a siphon - important nuances

Normal operation of plumbing fixtures is only possible if the siphons are correctly matched to sinks and sinks. Otherwise, you may face the problem of constant blockages. There are several types of devices:

• Pipe. These siphons resemble the letters S or U in appearance and can be collapsible or non-removable. There is a special plug at the bottom, which you can remove to easily clean the siphon. When installing a pipe siphon, it is important that the sink drain and the inlet into the sewer line coincide.
• Bottled. The siphon gets its name from the part in which the water seal is located. It is shaped like a bottle. The siphon is connected to the sewer using a straight or flexible pipe. The device is compact, easy to maintain: it is easy to disassemble and clean. The disadvantage is that you have to clean it often, because due to its complex shape the siphon often gets clogged.
• Hidden. This is a type of bottle siphon. During installation, only part of the structure (pipe) is visible, and the second part (bottle) is installed in the wall. Such siphons are quite expensive and difficult to install.
• Corrugated. The siphon is made in the form of a flexible tube that is suitable for all types of sinks. Such devices are cheap and easy to install, but their inner walls quickly become overgrown with grease and soap residue, and the pipe cannot be disassembled.

Pipe S-shaped and bottle siphons

Which option is better to choose?

For installation under a kitchen sink, it is better to choose a pipe siphon in the shape of the letter S, because Sewerage elements are often clogged with grease and kitchen waste, and such a device is easier to clean. For a bathroom sink, you can choose either a pipe or a bottle siphon, since here sink clogs are less common. If access to the device is free, then even if it becomes clogged, the problem can be easily solved.

As for materials, siphons can be made of polyethylene, polypropylene, brass or bronze. The most reliable models are metal, but polypropylene models successfully compete with them due to their lower price and acceptable quality. In addition to the shape and material, when choosing, you should take into account the diameter of the neck, the presence of an overflow and the design, if the model will not be covered by a cabinet or sink leg.

When connecting the washbasin and sink to the sewer, do not tighten the nuts too much. This can negatively affect the condition of the rubber gaskets and cause them to fail prematurely. If the connections leak, the gasket can be removed, dried, treated with sealant and reinstalled, and the connection can be tightened.

When connecting a sink, there is no need to contact specialists. The main thing is that before connecting the sink, carefully study the connection diagram and the sequence of work.

Preparatory stage

It is extremely important to prepare everything first.

The entire preparation procedure can be divided into several stages:

• Determination of height.
• Marking.
• Installation of fasteners.

According to the standard, the sink is fixed at a height of 85 cm. A horizontal line is drawn at this height. If your sink has a pedestal or comes with a cabinet, then the height of its installation will directly depend on the height of the support leg or cabinet.

Hole marking

As for marking, precise measurements are required for the hole of the fastener. There are two methods to measure the attachment points. The first option is to place the sink against the wall and place marks through the holes. The second method is more complicated; it involves taking all measurements with a tape measure. In both the first and second cases, it is more convenient to do the markings together. One can handle it if the sink has a support leg or cabinet.

Mounting the mount is the very last step of preparation. Holes are drilled in the marked places. A dowel is hammered into them, into which the required fasteners are screwed.

To connect the sink, it is imperative to use nuts, studs and special plastic inserts.

Stud mount

The stud should be screwed in to such a depth that when installing the sink there is sufficient distance for the fastening nut with a spacer placed under it. The stud should exceed the thickness of the shell by 15 mm. Now it's time to find out how to connect the sink to the water supply and sewerage system.

Connection to water supply

Equipment

The first step is to install the mixer. It is more convenient to install it when the sink is not yet attached to the wall. This is due to the fact that all fasteners are located under the sink.

Step-by-step instructions for connecting the mixer:

Take the pin from the faucet kit and screw it in.

Then connect the cold/hot water hose. Use an open-end wrench to tighten them. You should tighten it carefully, as there is a risk of stripping shallow threads.

Next, install the faucet into the hole on the washbasin.

On the back side of the mixer, place sealing gaskets and a pressure washer on the mounting studs. Now tighten the nut by hand.

When finished, all that remains is to tighten the nut with a wrench.

Mixer installation

When attaching the faucet, it is important to pay attention to the spout. If it is not rotary, it should be directed directly towards the center of the sink.

Now it's time to secure the sink to the wall. Place the sink onto the mounting pins. Then insert the plastic tabs and tighten the nuts with a wrench. If the bathroom sink has a leg, then install it at the same time. If the sink is in the kitchen, then here it either overlaps the bedside table or crashes into the countertop.

Studs for fastening the sink

After this procedure, all that remains is to connect the hoses to the central water supply. Make sure there are rubber seals inside the nut.

After connecting the hose, make sure the connection is tight. You may just need to tighten the nut a little.

Connection to sewerage

Siphon assembly

To organize the drainage of the sink, it is necessary to connect it to the sewer. Connecting to the sewer system begins with assembling the siphon. The siphon, or rather the water seal, will serve as a barrier to unpleasant odors. If you are installing a sink in the kitchen, then use an S-shaped siphon. If in the bathroom, then a bottle will do. Although the bottle version has a number of disadvantages, for example, it clogs faster.

The sink is connected to the sewer in the following sequence.

Insert the siphon outlet into the sink and secure it.

Screw the waste pipe to the siphon under the washbasin.

Direct this pipe into the sewer drain. Some siphons are equipped with smaller diameter pipes. Therefore, it will be necessary to use a rubber transition from a larger to a smaller diameter.

Upon completion, all that remains is to check the entire system for leaks.

This is how the sink is connected. Everything is very simple. If you have ingenuity, then all the work will be completed in a short period of time. Also, in addition, you can watch a useful video that will tell you the sequence of the sink connection process. If you have your own experience in this work, then write to us about it in your comments to this article.

For detailed video instructions for installation and connection, see below:

Connecting a sink is such a simple process that even experts recommend not turning to professionals for help, but doing everything yourself. There is nothing complicated about this, you just need to strictly follow the instructions given by the professionals.

1. Determining the height of the sink.
2. Marking.
3. Installation of fastenings for the sink.

There are standards for attaching a sink - for example, the mounting height is 85 cm from the floor. That is, you need to use a tape measure to measure the distance from the floor along the wall to 85 cm, and draw a horizontal line in this place with a simple pencil. Please note that this only applies to those types of sinks that do not have cabinets or stands. But if you have a cabinet under the sink, you don’t need to take any height measurements - just lean the structure against the wall and mark its level.

Marking must be carried out carefully and carefully, because precise measurements will be needed for the holes of the fasteners. Such measurements and marks on the wall at the future locations of the sink fasteners can be made in two ways. The first is the simplest - the sink is simply leaned against the wall at the location of the drawn line (where the height is marked) and the locations of the fasteners on the wall are marked with a pencil through the holes in the sink. The second method will be more complicated, but you won’t have to carry/move the sink - using a tape measure, measure the distance between the top edge of the sink and the hole, as well as the distance between the side edge of the sink and the hole for the fastener. These dimensions are then transferred to the wall.

Note:It is better to do the markings together, but if a sink with a cabinet/stand is installed, then one person will be able to cope with the task.

Installing the fastener is the last thing that needs to be done as part of the preparatory phase. Here, too, everything is simple - holes are drilled exactly in the marked places, dowels are attached to them, and the necessary fasteners are screwed into the dowels.

To connect the sink, you will need to use nuts, special plastic inserts and studs. The studs need to be screwed in to such a depth that no problems arise during installation of the sink - you will also need to install a fastening nut with a plastic spacer. Therefore, experts recommend choosing the right thickness of the stud - it should be 15 mm larger than the thickness of the sink.

How to connect a sink to the water supply

First you need to install it and it is more convenient to do this before the sink is already fixed to the wall - all elements of the mixer should be located under the sink. How to connect the mixer:

Note:When installing the mixer, you need to pay attention to its “spout” and if it is not rotary, then you need to immediately point it to the middle of the sink, even before fixing all the structural elements.

All that remains is to check the presence of rubber seals inside the nuts and connect the hoses to the water supply. After everything is finished, you need to open the water and check the tightness of all connections. In case of leakage, you need to tighten the fastening nut more.

After the faucet is installed, you need to attach the sink to the wall. This is done as follows:

• the sink is mounted on fastening elements built into the wall;
• liners are installed, which can be rubber or plastic;
• fixing nuts are installed and secured.

Note:If you are installing a sink with a pedestal or stand, then when fixing it to the wall you need to take into account the overall height of the structure.

How to connect a sink to a sewer

To organize the drainage of a sink into the sewer, you first need to assemble a siphon. It can have different shapes - straight (bottle siphon) or S-shaped. The first option is suitable for a sink installed in the bathroom, but the second option is suitable for a sink in the kitchen.

Step-by-step instructions for connecting a sink to a sewer:

1. The siphon outlet must be inserted into the sink and secured.
2. Under the washbasin/sink, a special pipe is screwed to the siphon, which is needed to drain the wastewater.
3. The pipe previously screwed to the siphon must be directed to the sewer drain. It is worth knowing that some siphons are equipped with a pipe of a smaller diameter, so you will need to use a special rubber transition from a larger to a smaller size.

After completing the work, you need to check how well the water is drained in the sink, and whether there is a leak somewhere in the siphon. If any mistakes were made in the work, they will appear fairly quickly. The following points will indicate that it is necessary to repeat the process of installing/connecting the sink, taking into account errors.

A process such as installing a washbasin is simple; the involvement of specialists is not necessary to carry it out. Washbasins differ from each other in appearance, in the method of fastening, in the place of their installation, and based on these data, the sink is installed and connected to the sewer.

Methods of fastening and installation of the washbasin depend on the chosen model and the material from which it is made.

• The first method of fastening is standard and is done using studs. This method is used for washbasins made of lightweight materials. Having prepared the place, the locations for the holes are marked and then drilled. Next, the dowels with studs are screwed in and the bowl is mounted. Afterwards, a connection is made to the sewerage system using a siphon and adjacent parts. If the plumbing fixture has an overflow, an additional tube is installed to the siphon. Installation using this method can be done with your own hands;
• The next mounting method is the same standard, only a bracket is used instead of screws. After drilling the holes, plugs are hammered in, then the bracket is screwed on. The bracket is the most reliable and high-quality fastening method. Having finished screwing the brackets, you can attach the sink to them and connect the siphon to the sewer system. The sink bracket can be made of different materials, which is why the bracket and its rigidity differ. Their selection must be made depending on the selected sink model, taking into account the load on them .

Sink brackets

Studs for fastening the washbasin

Types of brackets:

• The cast iron bracket is a T-shaped post with a special platform for fastening. The cast iron bracket is reliable and of high quality;
• welded steel brackets, shaped like the letter T or L;
• brackets, the shape of which resembles a frame. This method is as simple as the previous one and you can do the fastening yourself;
• The cabinet sink method is used when choosing a washbasin that is built into a piece of furniture, a countertop, or into a specific, specially purchased cabinet. This method is suitable for a small bathroom.

Preparatory work

Installing and connecting a sink with your own hands is a simple process that can be divided into several stages. The first stage is preparatory activities for installing the washbasin.

Choosing a place in the bathroom or dismantling an old washbasin. In a small bathroom, it is better to use a corner sink, or one built into the bathroom furniture, a countertop, a cabinet, or a washing machine, which can be placed in the room without taking up much space.

Determining the height of the sink. If it does not have additional accessories, then the standard mounting height is 85 cm, even for a small bathroom. Having noted this height, a line is drawn along which the upper level of the washbasin will be attached. In the case of using a tulip sink or a washbasin mounted into a countertop, there is no need to determine the height of the fixture of the plumbing fixture, since it depends on the height of the pedestal or countertop.

Mounting markings

Marking the mounting locations on the wall is done as follows: to accurately drill the necessary holes for making fastenings, you need to attach the sink to the wall, aligning the upper level of the sink with the marked line and mark them on the wall through the mounting holes located in the bowl. It is better to carry out the steps to mark the mounting holes with your own hands together. It’s another matter if you use a sink, a tulip, or one installed in a countertop; by placing the bowl on a footrest and moving it towards the wall, you can easily make a mark.

Preparing the mounting site

Checking the level

Installation of fasteners

The next stage is the installation of fasteners, the choice of which depends on the method of installing the sink:

• According to the markings of the mounting holes, they are drilled;
• dowels are driven into these holes;
• Special pins are screwed into the dowel. It is screwed to a depth such that its protruding edge allows you to secure the sink and tighten the fixing nut. The length of this edge of the stud should not be small, but slightly more than the thickness of the bowl, plus the distance for the nut.

Connecting the sink to the water supply

The third stage is connecting the washbasin to the water supply system with your own hands. This stage begins with connecting the mixer. It can be attached after the installation of the washbasin is completed, but it is recommended to do this first, since all connections are made at the bottom of the bowl. Also, depending on the type of sink, the faucet may be mounted on a wall or countertop.

Washbasin mixer

The mixer mounting diagram is as follows:

• special fastening pins are screwed in;
• Next, a hose is installed, through which the water supply is supplied. They need to be tightened using an open-end wrench; moderate efforts should be made when tightening them;
• hoses are now installed to supply water through the holes in the washbasin;
• Next, sealing rubber bands, a washer for pressing are put on the studs for fastening on their reverse side and a nut is attached;
• The last step is to tighten the fastening nuts.

Having connected the plumbing fixture to the water supply with your own hands, you can proceed to the next stage, which is installing the washbasin:

• this stage is the easiest, you need to put the sink on the studs, insert plastic spacers and tighten the nuts;
• When using a tulip sink or a sink built into the countertop, it is fastened to supporting elements.

Connection to sewerage

Having completed the installation work and connecting to the water supply, you need to connect the sink with your own hands to the sewer. This process begins with the installation of a siphon. When installing it, you need to consider whether the sink has an overflow or not. If yes, then the siphon must be equipped with an additional tube to transfer water into the sewer system.

Types of siphons and material for their manufacture

A siphon is a structure resembling the English letter S, the location of which is located immediately under the sink. Its purpose is to connect to the sewerage system to remove water. Siphons come in different types:

• bottle type siphons. The advantages are the presence of a water seal, the ability to connect the water drain from the washing machine, and independent regular cleaning. This type is often used with an overflow;
• Tubular siphons, which resemble a curved pipe. A seal is formed in the bend of this pipe, preventing the appearance of specific odors;
• siphons are corrugated, reminiscent of tubular siphons, only with the difference that, due to their plasticity, they can take any shape, becoming more compact;
• Siphons with overflow are all of the above varieties with an additional branch of the pipe leading from the siphon to the top point of the sink to prevent water from overflowing from it.

Tubular siphon

Siphons are made from different materials:

• cast iron siphon, its advantages are corrosion resistant, strength. The cast iron siphon also has disadvantages, such as poor cleaning and a complex dismantling process. The cast iron siphon is used only in bathrooms;
• brass siphons, its advantages are durability, strength, corrosion resistance, easy dismantling;
• Siphons made of plastic, the most common type, are quite durable due to their affordable price, ease of installation and dismantling.

Siphon installation

• it is necessary to place the siphon outlet in the bowl and secure it. If the sink has an overflow, an additional tube is installed;
• the pipe is screwed on;
• the end of the pipe must be inserted into the sewer outlet. If the pipe size is small and does not correspond to the sewer hole, an adapter called a cuff is used;
• Upon completion of installation work, you need to check all connections to ensure there are no leaks.

Siphon installation

The instructions for installing and connecting a sink discussed above are used mainly for wall-mounted sinks or if you need to hang a corner sink that is installed in a small bathroom. When installing a tulip sink, or using a countertop, the fastening method is slightly different. A sink that is mounted into a countertop or cabinet has the advantage of good stability and fastening occurs without drilling the surface of the walls.

Rules for attaching a tulip shell

When attaching a tulip shell, there are certain rules:

• as with standard mounting, the tulip must be placed against the wall to determine the location of the mounting holes;
• Next, a cast iron bracket is attached, with which the tulip sink is attached. Its fastening is carried out according to the same principle as a dowel with a hairpin;
• The bowl is attached to a screwed bracket, while simultaneously moving the foot of the structure. It should be noted that the tulip can be monolithic, separate, with a shortened footrest, which is used in a small bathroom;
• then the siphon is installed and then the mixer;
• The final stage is the installation of the footrest, which will hide all communications.

Tulip sink installation steps

So, installing a bathroom sink yourself does not require the help of specialists. Its quality and reliability depend on the materials used, DIY fastening methods, and sink models, thanks to which some types of washbasins can be placed in a small bathroom due to their compactness.

Carrying out renovation work in a house requires special attention to every detail. So, an important part of the process is the installation and connection of sinks in the kitchen and bathroom. You can entrust these procedures to a professional plumber. However, these steps are not that difficult. You can easily connect the sink yourself. This does not require specialized knowledge. Connecting sinks yourself will allow you to significantly save money and get the job done in a short time.

Preparatory work

The basic technology for connecting sinks in the kitchen and bathroom is the same. Let's consider the main stages of preparation for the connection process:

1. Installation of mounting location. Determining the height of the sink.
2. Carrying out marking work.
3. Installation of fasteners for fixing the sink.

Mounting location installation

After determining the location of the sink, you need to determine the height of its installation. It depends on its type.

The sink located in the bathroom can be installed on a pedestal or without additional parts. If no additional parts are attached to the sink, the average height of its location should be 85–90 cm; if the sink being installed has a support horn or other parts for support, the height of its installation should correspond to the height of the supporting parts.

The height of the sink installed in the kitchen must be the same as the height of the kitchen cabinet into which it will be installed. To fix the selected height level on the wall surface, you must draw a horizontal line.

Carrying out marking work

There are holes for fastening on the surface of the sink. It is necessary to attach the sink to the wall with the side with the holes. In this case, you should observe the established height of the sink - be guided by the horizontal mark. On the surface of the wall it is necessary to mark the places where the holes for fastening the sink should be located. To ensure the work is done correctly, it is recommended that two people do it together. In this case, one person will hold the sink, and the second will mark. For ease of work, markings can be made from below.

If the sink being installed has additional support in the form of a pedestal or bedside table, the plumbing fixtures can first be placed on the support, and then the mounting location can be marked.

Installing fasteners for fixing the sink

Installation is carried out in several stages:

1. Drilling holes in the marked places for fastening.
2. Installation of fixing dowels in the holes. It is recommended to use plastic dowels.
3. Installing the mounting stud. Produced by screwing.

Determining the length level of the fastening stud. When choosing the length of the mounting stud, the thickness of the shell and the thickness of the fixing nut should be taken into account. Usually it is 1.5–2 cm.

Making a connection

How to connect a sink in the kitchen or bathroom yourself? The work is carried out in several main stages:

1. Carrying out installation work on the mixer.
2. Fixing the product on the wall surface.
3. Installation and connection of the water supply system.
4. Connecting to the sewer system.

Carrying out installation work

To optimize and simplify the installation process, it is recommended to first install the faucet, then connect the sink.

The mixer is installed, observing strict rules for its location. Installation must be carried out strictly at right angles to the surface or side of the sink.

Carrying out the work:

1. Installing the fixing pin on the faucet. Some faucet models require 2 studs.
2. Connection of pipes for cold and hot water. They should be secured using an open-end wrench. The degree of tightening is medium.
3. Through the hole in the sink, it is necessary to stretch and install hoses for supplying cold and hot water.
4. Installing the fixing pin. It must be strengthened with sealing materials. Usually a special gasket is used. It is mounted on the inside of the stud. It is sealed with pressure washers and nuts for fastening.
5. Tightening the nuts. This is done using a wrench.

The installation procedure for the mixer is presented in the following video:

Fixation on the wall surface

After the sink has been connected to the water supply, you can secure and fix the sink on the wall surface.

The prepared device must be placed on the fixing studs mounted in the wall.

Install plastic or rubber liners.

Then install and tighten the fixing nuts.

Note! If you are installing a sink that has supporting elements (for example, a pedestal or a bedside table), you need to take into account their height and only then carry out the procedure for fixing the sink.

Installation and connection of the water supply system

It is necessary to connect the cold and hot water pipes attached to the sink to the piping system. They should be fixed using a wrench. The degree of curl is medium.

In order for the joint to have the greatest density, it is recommended to install an intermediate gasket between the materials. It is recommended to use a rubber product.

After connecting the pipeline, it is necessary to check its reliability level. To do this, turn on the water and check whether water leakage occurs. If this occurs, it is necessary to tighten the nuts in the places where the pipeline is attached.

The basic sink connection diagram is shown in the figure:

Connecting to the sewer system

To connect the sink to the sewer, you need to connect a siphon to it.

Devices of various shapes can be used. Experts recommend using an S-shaped device on kitchen sinks. This type of siphon is the least susceptible to clogging.

To install a bathroom sink, you can use a bottle-shaped device. The sink drain in this siphon is more susceptible to contamination, so it is only suitable for use in the bathroom. In the kitchen, this type of siphon will need to be cleaned weekly.

Carrying out work on connecting the sewer system:

1. Installing and securing the siphon on the sink sink.
2. Connecting the pipe to the device. It is recommended to use corrugated pipes in kitchen areas, and pipes made of hard materials in bathrooms.
3. Connecting the installed pipe to the sewerage system. If there is a difference in the diameter of the pipes, it is recommended to use an adapter - a cuff. It is made of rubber and allows for good sealing of the joints.
4. Connecting the system and checking it for leaks.

Identifying errors in operation

If mistakes were made when connecting the sink, they may be indicated by the following:

• the appearance of an unpleasant odor;
• humidification of the siphon during operation of the sink;
• the appearance of leaks and puddles under the sink;
• difficulties arise and speed slows down when draining water.

Check the installation carefully.
