How to assemble a knee under the sink in the kitchen. How to assemble a siphon for a sink with your own hands. The main task of the drain valve

Replacing a siphon for a sink is a very simple task if you follow the recommendations of experts. It can be attached in several ways, so you need to know how to unscrew and connect it in each case.

Purpose

A siphon is a pipe with bends through which drainage occurs. drain water from the bath, sink, washing machine to the sewer system.

The purpose of siphons can be as follows:

when draining, a small amount of water remains in the siphon, which serves as a special sump, thereby preventing the penetration of unpleasant odors, gases, sewer noise back into the home;
does not allow various bacteria to multiply;
prevents the formation of blockages of various origins.

Types: pros and cons

There are several main types of siphons. It is necessary to consider some of their characteristics, disadvantages and advantages.

Pipe type

It is a simple device in the form of a rigid tube, bent in the shape English letter U or S. This type can be either solid or collapsible. There are options in which a special hole is provided at the lowest point for extracting various particulate matter. With a pipe type of siphon, increased accuracy of its assembly is required. The advantage of this type is that it is not necessary to disassemble the entire siphon to clean it, completely remove the lower “knee” from it. The downside is that due to the small hydraulic seal, with infrequent use, unpleasant odors may occur; due to insufficient mobility, it will not be possible to install it as it should.

bottle type

It has the largest distribution compared to others, although it represents the most complex structure of all. It acquired its name due to the fact that in the area of \u200b\u200bthe water lock it has the shape of a bottle. Its main advantages include quick and convenient installation, even in a limited space, disassembly is quite easy, cleaning does not take much time, small things that get inside will not go into the sewer, but will sink to the bottom of the bottle. Only with its help you can connect a washing machine or dishwasher without inventing for them additional outlet sewerage. A significant disadvantage is that contaminants settle at the junction of the siphon with the sewer pipe and cause it to become clogged.

corrugated type

It is a flexible tube that can be bent in any direction. This is one of its main advantages when it can be installed in those places that are inaccessible to the previous two. Its advantages include a relatively low price, and a minimum number of leaks due to one junction. The minus is an uneven surface that collects various mud deposits on itself, they can be removed only when the structure is disassembled. Can't pour out hot water into the sewer if the siphon is made of plastic.

Materials and equipment

The siphon material must be resistant to chemical and thermal aggressors, so it is made of polyvinyl chloride, chrome-plated brass or bronze, as well as propylene. Structures made of brass or bronze are quite expensive, look aesthetically pleasing and are quite prestigious, but nevertheless they are resistant to corrosion and various oxidizing agents. Devices made of PVC, polypropylene and plastic are much cheaper and also have simple assembly, stability of connections, but not particularly durable.

A typical set of any siphon consists of the following elements:

corps;
rubber gaskets 3-5 mm thick, preferably from oil-heat-resistant (white) or silicone plastic;
protective grille with a diameter of up to 1 cm;
nuts;

pipe (outlet or outlet) to install the gasket. It has 2-3 distinct rings, a side, and can also be equipped with a drain for connecting a dishwasher or washing machine;
outlets to the sewerage;
connecting screw made of stainless steel with a diameter of up to 8 mm.

How to choose for kitchen and bathroom?

A siphon for a kitchen or bathroom should be chosen, following, of course, practical purposes. But the features of the room should also be taken into account.

In the bathroom, the siphon should ensure the absence of odors from the sewer, as well as drain quickly and on time Wastewater. Siphons that have connecting elements made of hard materials, it is better not to purchase, as the installation will be difficult. In this situation, the corrugated type is an adequate option. drain tube. Due to the flexibility of the device, it will not be difficult to install and change it in hard-to-reach places in the bathroom, all the more so it will be quite easy to replace the siphon.

For the kitchen, the bottle type of siphon is most suitable., because various parts of fatty and food waste will not fall into the sewer and contribute to its clogging, but will settle to the bottom of the flask. Moreover, if the device itself becomes clogged, it can be easily and conveniently cleaned. For sinks in the kitchen with two drain holes, types of siphons, additionally equipped with overflows, are perfect.

You can, of course, use other types of siphons, but only rarely and in confined spaces, because unpleasant odors can occur, since they have a rather short water seal.

Assembly and installation

The assembly and installation of siphon structures for a washbasin, sink or bath usually does not take much time, and also does not require special skills. However, various little things should be taken into account, so as not to redo everything several times, whether it is the installation of a washing machine or dishwasher, as well as other various equipment. When buying a siphon, you need to check whether all the elements are present, and also disassemble it with the instruction manual.

for washing

Even those who have never done this can assemble the siphon.

However, several nuances should be taken into account.

All connections must be tight. It is necessary to carry out a tightness test from the bottom plug, which is usually under the pressure of sewage. When purchasing a siphon, it must be well checked for the presence of marriage, which can violate the integrity of the gasket.

At the time of buying assembled siphon it is necessary to check the presence of all gaskets in it, make sure that the elements of the device are well fixed and tightened.
The assembly of the kitchen siphon must be carried out manually to control the clamping force, and also so as not to break the product.
When installing all siphon connections, especially the bottom plug, the gaskets of the device should be well fixed so that there are no leaks. This is where the sealant comes in. The siphon elements must be screwed to the end, without pressing hard.
Having completed the connection of the outlet pipe, due to which the installation height of the siphon itself is regulated, it is necessary to fix the fixing screw, while removing excess sealant.

Before installing the siphon, preliminary work is carried out to begin. For example, in the kitchen there is a brand new metal pipe, so it needs to be connected to the siphon, but before making this connection, it will need to be cleaned of mud deposits and a rubber gasket should be installed. However, if a plastic pipe is installed, then first you should bring its end to a certain level (not higher than half a meter), only then you need to put a special adapter on it.

Next, the obsolete siphon is dismantled using a screwdriver to unscrew the fixing screw. The place for planting a new siphon should be carefully cleaned of grease, mud deposits and rust. After all these manipulations, you can put the siphon on the sink. The main component of the siphon must be manually connected to the pipe under the sink. In the instruction manuals for the siphon, it is immediately recommended to attach a washing or dishwasher, but still it is worth, first of all, to connect the structure to the sewer system, to carry out the initial test, in which the auxiliary outlets are closed with special plugs that are part of the siphon kit.

After that, a check is carried out, during which there should be no leaks. Only then can additional equipment be attached, drain hoses which are secured with clamps. When installing, it is important that the drain hose coming from the siphon is not twisted or kinked.

for washbasin

As usual, you need to disassemble the old device. It is necessary to unscrew the rusted screw in the drain grate or remove the lower section of the obsolete siphon. Then wipe the drain hole.

Assembly can be done as follows:

choose the widest opening of the drain device, attach the widest flat gasket there and a cap-cap on the side;
screw the union nut onto the branch pipe, pull the conical gasket with the blunt end onto the branch pipe inserted into the dorsal opening. And screw on the tube. Some options involve combining a pipe with a drain funnel;
the gasket and nut are mounted on a corrugated drain pipe, which is then screwed to the siphon;
do not overtighten the siphon elements during assembly, so as not to damage them.

Having successfully completed the assembly of the structure, you can continue its installation.

Above the washbasin must be placed metal mesh with a ring. fake drain device under the drain hole of the sink, carefully holding and straightening it.
Screw the connecting screw into the mesh.
Connect the resulting structure to the sewer system using a corrugated pipe, which should be stretched to obtain the required length.
Carry out a test in which the device must fill with water, providing a water lock. There will be no leakage if the structure is properly assembled and installed.

For Bath

The bathroom siphon is assembled in almost the same way as the previous two. When installing a new siphon on the bath, you first need to clean all its drain holes with sandpaper for a good connection of the gaskets in the future.

What is a siphon?

This is a device that connects the sink to the sewer drain pipe and performs a sanitary function.

In addition, the siphon is the primary barrier in which various wastes accumulate that accidentally enter the water. Thus, correctly chosen and competently installed device, in addition to providing a comfortable microclimate in your bathroom, will drastically reduce the likelihood of clogging the waste system. In this article, we will tell you how to assemble a sink siphon correctly.

Types of siphons

The principle of operation of the siphon was described by Archimedes in the law of communicating vessels. In short, the simplest siphon is a pipe bent in the form of a knee, in which water is constantly located (a water seal), and it does not let stench out of the sewerage collector.

Such devices consist of three nodes - a receiving pipe ( different designs) and drain pipe. Despite their similarity, the scheme of such devices has different design features. Let's briefly consider their types.

Corrugated

The simplest type of device.

It consists of a receiving pipe (attached to the sink and connected to the drain) and a drain pipe by shaping it into a knee shape with fixation by tying it to accessible surfaces or using special plastic molds.

For example, special shapes included with washing machines.

Such devices are very simple, cheap, but have a limited range of applications due to the inability to connect more than one drain point.

Trubny

As a rule, such products are made of copper alloys (brass, bronze) or stainless steel and, unlike their ancient predecessors, along with functionality, they also have very high aesthetic characteristics that allow them to be used as a decorative element.

The physical properties of such devices are beyond praise, but not everywhere it is possible to connect them due to the special requirements for the installation of the sink and the connection point on the side of the sewer line.

In addition, their cost is very high, which puts such siphons in the category of VIP - products for VIP - persons.

Bottle

The most common type of pipe siphons, the most compact and functional, and the low cost makes it almost indispensable for the construction of economy class systems.

Number of connected devices ( washing machine, dishwasher, overflow, etc. e) to this design is limited only by its throughput.

If the existing outlets are not enough, then you can always connect an additional adapter (sold in assortment) between the bottle and the inlet pipe, which will provide you with an additional connection.

Siphon installation

Installing a corrugated siphon does not present any difficulties. It consists in installing the corrugations in a rubber bushing on sewer pipe one end, and the other into a pipe attached to the sink. After that, in a certain area, the pipe is shaped into a knee and fixed with plastic frame or otherwise, in any other way.

In this option, it is very important to provide for a bend of such a shape that the height of the water column in the knee is at least 7–10 cm, otherwise it may be forced through by the pressure of sewer gases and unpleasant odors may appear.

The installation of luxury pipe products will most likely be carried out by specialists who make repairs to you, so we will not dwell on them in detail. We only note that such systems require a very accurate calculation and ideal alignment of the siphon outlet pipe and the sewer intake pipe.

Installation of a bottle siphon

Insofar as different manufacturers offer some design differences, before starting work, we advise you to carefully read the instructions for an accurate understanding of the process. So, we start with the installation of the intake pipe.

To do this, we bring it from below to the drain hole of the sink, put it on its side sealing gasket and cover with protective decorative grille. Next, insert the clamping bolt into the hole and carefully tighten.

In this case, it is very important to prevent the grate and nozzle from scrolling, since in this case, the gasket is likely to be displaced and leakage may occur.

In addition, when tightening, the force should be limited to prevent the occurrence of dangerous deformations of the rather fragile material of the product.

When the pipe is installed, proceed to the assembly of the siphon. We put a coupling nut and a cone seal on the outlet pipe, then we string the siphon bottle to the required depth and fasten it with a special plastic nut, after which it remains to install the revision (for cleaning) siphon cover.

We do this by simply screwing it on using a sealing rubber (or polyurethane) ring. The siphon is ready.

Now we need to connect to the sewer main system. To do this, a special rubber gasket, and if the diameters do not match, a suitable adapter is inserted into it and one end of the connector pipe is inserted into it, the other is inserted into the siphon inlet socket.

The connecting tube that comes with the siphon has a certain length limit, and if you don’t have enough of it, you will have to buy a separate hose of the required length.

When installing a sink with an overflow system, there are two options.

Ceramic sink. She has an overflow water outlet built into the body in such a way as to ensure that it drains directly into the siphon pipe.
Metal (kitchen). In this case, drainage is organized through an additional tube drawn from the drain hole to the siphon glass or using a special design of the siphon itself (the so-called kitchen siphon).

There are situations when the drainage scheme provides for the connection of two or more sinks. In this case, as a rule, a system similar to that described above is assembled.

In this case, two drains with the help of pipes and a tee (tees) are reduced to one siphon. With such a scheme, a much more significant flow of water is formed, so it is necessary to take into account throughput siphon and, if it is insufficient, try to pick up another product or arrange a separate outlet for each drain point.

In conclusion of the topic, I would like to note the relative complexity of can structures and a large number of their connections.

As you can see, there is nothing super complicated in this work, so give 500 r. and even a more professional plumber for installing a siphon is considered unreasonable. It would be right to increase the purchase budget by this amount and purchase a more reliable and high-quality device.

Mounting plumbing equipment both in the kitchen and in the bathroom, it involves connecting not only to the water supply, but also to the pipe sewer system. Most owners of apartments and houses mistakenly assume that the connection task must be performed by professionals. In fact, the installation of a siphon is not so complicated and no specialized tools and tools are required to complete the installation. a large number time. After reading the following, everyone can find the answer to the question of how to connect the siphon to the sink.

First of all, you need to correctly select the siphon itself to ensure long-term and high-quality operation of plumbing. There is a big difference between designs for draining a bathroom bowl and siphons for connecting a kitchen sink. There are the following options for siphons for the washbasin in the bathroom and the bathing bowl itself:

Bottle design. This product has a fairly large size, so this type of siphon is selected, taking into account the fact that under the sink there will be a sufficient amount free space. The advantages of the design include the presence of a shutter, the provision of self-cleaning in a regular mode, an overflow drain device. In addition to these functions, this type of design allows you to connect the sewer drain not only to the sink, but also to the washing machine and dishwasher.
Corrugated siphon. Such a product can complement the kitchen sink, bathtub and washbasins. various types. This design endowed with one drawback associated with the complexity of cleaning the sewer, which is possible only with the use of special equipment. The advantages include flexibility, which provides an opportunity in the most inconvenient places.
Pipe construction. This type of product is intended to create sewer drain from shower and bath trays.

Bottle and knee designs

To connect the washbasin in the room for taking water procedures, that is, in the bathroom, professionals advise using a bottle-type siphon. To understand why this type is preferable, will consider the composition and features of this type of equipment.

Connecting a siphon of this type is a simple operation and may well be performed by the owners on their own. The installation procedure is to connect the device with one end to the sink or bath drain, and the other end to the outlet of the sewer pipe.

The product device itself is extremely simple, and care for it is not special difficulties. The main thing in the installation process is to make sure that all sealing rubber gaskets are installed and not a single one is lost or forgotten. This moment is very important, and not so much for the installation process, but for the convenience and comfort of operation in the future, because such rubber products will ensure that there is no wastewater leakage.

For kitchen sinks the best choice is a knee siphon made of metal or plastic. The installation of this kind of design as a whole practically repeats the connection of a bottle siphon. The differences lie in the fact that instead of an element that is just called a bottle, it is necessary to install a curved rigid type element called a knee.

The uniqueness of this design lies in the fact that it can only be installed if the sewer pipe is located in the wall.

Process details

Distinctive features of the arrangement of the drain siphon for the bathroom lie primarily in the fact that the bathroom has not one, but a pair of drain holes. One of them, as expected, is located at the very bottom of the bowl, and the second is installed on the front side at the top of the product. It is this second product that protects the bathroom from overflow. The siphon for connecting the bathing bowl to the sewer consists of such components as:

corrugated flexible plastic tube, which is located on outside walls of the product to ensure the flow of used water directly into the sewer pipe;
a polymer bowl that allows you to equip a drain at the bottom of the bathroom;
knee;
a connecting pipe that allows you to connect the siphon and the sewer.

For the installation, no specialized tools are required; in the process of work, you will need:

Corrugated tube.
Silicone sealant.
Adapter-coupling made of rubber.
Tow or mounting tape.

The difference between the process of connecting the sink and arranging the drain in the bathroom is that before installing the siphon itself, it is necessary to install a metal rim on the drain hole in the upper part of the bathroom. After being installed given element. it is to it that the siphon is attached using a specialized bolt. As soon as these manipulations are completed, the knee of the product is installed and the process of connecting the structure to the central sewer is performed.

Washbasin connection

To arrange the connection of the sink in the kitchen and its subsequent comfortable operation, it is recommended to use products with a drain hole of 3.2 cm in diameter. It is these hole parameters that are considered the most convenient and at the same time compact, in addition, this parameter ensures ease of installation of the siphon for various sinks and ease of subsequent operation.

Before undertaking the installation of the product, you should first get acquainted with its device. Any siphon for connecting sinks in the kitchen is a product consisting of such constituent parts, as:

throughput plastic pipe, equipped with a metal insert;
pipe gasket made of latex;
nuts with a diameter of 3.2 cm made of plastic;
cuff-skirt made of elastic and soft plastic, with a hole in it 3.2 cm in diameter;
tightening screw made of steel;
overlay for the drain part, also made of steel;
the body of the product, called the bottle;
bottom plug;
rubber gasket in the form of a ring;
plug for locking the drain, consignment note.

In the process of installing siphons of this kind on a sink or washbasin, maximum attention should be paid to such a parameter as the tightness of each connection of the structure.

And a siphon is installed in the bathroom. It connects directly to the sewer system. Anyone, even a non-professional, can install it and, accordingly, assemble it. This article will cover the question of how to assemble a sink siphon. Looking ahead, in most cases, one screwdriver is needed for this job.

The siphon is not easy to drain dirty water. For example, it may linger large debris that has penetrated through protective grille. Accordingly, this reduces the risk of blockage of the sewer pipe.

Moreover, the special design of the device forms a water seal. The presence of a knee in the siphon does not allow an unpleasant odor to penetrate from the sewer system. A water seal is formed due to the constant presence of water inside the siphon.

The siphon is made of plastic, metal and combined. In particular, brass with a glossy chrome finish looks beautiful. It is worth considering buying it if you do not plan to install a tulip, cabinet or cabinet under the sink. In such cases, in addition to reliability, the siphon must also have a beautiful appearance. Agree, looking at a plastic siphon is not as pleasant as looking at a metal one, and even shiny one.

Among other things, this device is made of other metals, such as copper and bronze. But they need special care because they oxidize over time.

If you need to maintain a certain style of bathroom interior, then not only the siphon, but also the pipes, faucet and other elements must be made of the same material.

Most often bought plastic siphons. They have a number of advantages:

Low price.
Strength.
Light weight.
Chemical resistance.
Ease of assembly and installation.
The ability to install in the most inaccessible places.
Limestone deposits do not form on the plastic surface.

In addition to the choice of material, the siphon also has different types Let's look at them further.

This design is popularly called simply corrugation. It consists of a bendable tube, which can be given any shape, and in particular, bent to form a water seal. The corrugated siphon is fixed with a special clamp. The main advantage is the low cost, as well as the ability to freely move the sink to the side. The corrugation will stretch without difficulty and acquire the necessary shape.

This product resembles a corrugated design. The only difference is that the siphon has sufficient strength and rigidity. In my own way appearance such a siphon is a curved tube of the required shape for the formation of a water seal. It connects to the sewer pipe and sink without all kinds of nuts. However, it has a clear drawback. If you need to move the sink, then it will be difficult to do so. Moreover, such siphons are poorly cleaned. Given this, all more people abandon the pipe siphon.

Bottle

Based on the name, the shape of such a device resembles a bottle. Its device is very simple. In the existing flask there is a sump, which, if necessary, can be easily cleaned. It also has an output corrugated pipe. The main advantage of the bottle design is that it is very easy to maintain. It is enough to unscrew 2 nuts and the siphon can be completely removed from under the sink for cleaning.

Siphon device

Almost all siphons have a similar device. For this reason, consider the main elements. After that, we will find out the details of its installation.

Cork. It can be rubber, metal and plastic. Attached to it is a ring and a chain. It is used when it is necessary to draw water into the sink, for example, for a small wash.
Protective grille. Its installation is carried out only with a rubber gasket. The grate prevents large debris from entering the sewer, and the gasket makes the drain airtight.
outlet pipe. This branch pipe has a small side and embossed rings on which the gasket is placed. Due to this shape, the gasket does not move when twisting. It is clamped with a plastic nut.
Removable knee. This element most often needs to be removed for cleaning. It is fixed with a plastic nut. Under it is installed cone gasket.
Overflow outlet. A flexible corrugated hose is attached to it using a flat or conical gasket. It, in turn, is connected to the main structure of the siphon.
overflow pipe. Not all types of siphons with overflow, most often for sinks it is not.

You can find other details of the siphon on the diagram provided:

Siphon assembly and installation

The siphon always comes with assembly instructions. This greatly simplifies the process of working if you are doing this for the first time. pay attention to important nuances, following which you will assemble the siphon with high quality:

Tightness - important requirement each connection. Even if you bought assembled structure, check for the presence of sealing gum at each joint. Also make sure all nuts are tight. Regarding the latter, do not overdo it, because the plastic thread is very easy to break.
When installing a siphon, a sealant is often needed. For example, some rubber gaskets can be smeared with clear silicone. This will make the connection even better.
If the design has a screw to fix the protective grille, then make sure that there is a metal nut in the main pipe. When tightening this bolt, check correct location sealing rubber. Also, do not overtighten the nut, otherwise its threads can be stripped.
The connection of the drain pipe to the sewer pipe must be carried out only through rubber compressor.

The process of assembly and installation of the siphon is carried out simultaneously. Apply a rubber seal to the drain hole in the sink and fix the protective grille. In some types of gratings, the gasket is installed from below. Due to this, the water in the sink will not stand. If the design involves the installation of a gasket from above, then it can not be used, and the docking site should be thoroughly lubricated with sealant.

Attach the intake pipe from below under the sink and fix the drain grate with a screw or a plastic nut (depending on the design of the siphon). Make sure that the flange with the gasket does not scroll. Otherwise, the gasket may move and the connection will not be tight.

Next, you need to assemble the main part of the siphon. On the outlet pipe under the sink, put on a nut and a cone gasket. After you put on upper part siphon to the required height and fix it with a plastic nut.

It is necessary to put a flat rubber gasket in the siphon cover and screw the second part of the body.

When connecting all these elements, it is not necessary to use sealant. This is because after a while you will need to unwind the siphon to clean it.

Now put on the outlet drain pipe, which should also have a nut and a rubber cone gasket. Attach a corrugated hose to it, which you direct into the sewer hole.

Finally, place a container under the sink and turn on the water to check the structure for leaks. If no leak is found after draining the water, all work has been done successfully. Otherwise, it will be necessary to correct the rubber gaskets.

Separately, it is worth mentioning the docking of the siphon with the sewer. In most cases, the hose diameter is 50 or 40 mm. If the corrugation has Ø50 mm and the same size of the sewer pipe, then the presence of a sealing gum on the socket is sufficient. If the corrugation size is 40 mm, then you need to buy rubber cuff with transition to Ø50 mm.

So, we learned with you that the installation of the siphon and its assembly can be done independently. Now, if in the kitchen or in the bathroom it will be necessary to replace the siphon, then you can do it on your own. In addition to this article, we suggest that you familiarize yourself with the video and assembly and installation diagrams for this small but important device.

Video

That video tells in more detail about the intricacies of assembling and installing the siphon on the sink:

Scheme

The diagrams show the details of the assembly and installation of the siphon:

Even a novice can handle installing a siphon under the sink in the kitchen without resorting to the help of a specialist. The designs of modern siphons are designed for assembly by hand, and only in rare cases may need a screwdriver.

A siphon is a pipe (less often several pipes) with a bend, which serves to drain dirty water into the sewer. It is thanks to the bend that a small part of the water remains in the pipe, forming a kind of sump. He, in turn, does not unpleasant odors and noise from the sewer pipe to enter the room.

Siphon device

Siphons for drains are most often made of chrome-plated brass or plastic (propylene, polyethylene, PVC). Brass products oxidize over time and accumulate dirt. It is better to give preference to a plastic siphon. Such a product does not corrode, does not rot, it is wear-resistant and durable.

Consider the siphon device using an example plastic product. Standard equipment siphon includes:

Assembling a siphon for a kitchen sink

Each siphon purchased in a store or warehouse must be accompanied by an instruction with a product assembly diagram. The assembly will not cause difficulties even for the one who first picked up the siphon. But in order to avoid leakage in the future, when assembling the product, the following points must be taken into account:

Siphon installation

When purchasing a siphon, it is necessary to check the product for the presence of all parts of the device. It often happens that even in a closed package, some parts are missing.
When assembling the siphon, all elements must be dry and clean. Dirt or sand on the rubber gasket or threads can cause leaks.
When installing a siphon, the height of the outlet of the siphon from the floor must be an order of magnitude higher than the height to the inlet in the sewer pipe. Under this condition, a certain slope is formed, favorable for the flow of water.
