About such a simple but extremely important element drainage, like a siphon, we remember only occasionally looking under the sink or in case of sewer blockage. ? Siphons are installed under the sinks in the bathrooms and in the kitchen. At the same time, in the kitchen, the siphon can combine two sinks and a dishwasher at once, and in the bathroom - a washbasin and a washing machine. The purpose of this device is to prevent the spread of sewer odors in the room and facilitate the process of clearing blockages.
To choose a siphon for a sink (the cost is about 120-200 rubles), and then install it correctly, it is worth considering its possible design features and appointment.
Consider a generalized set of siphons. When buying in a kit, you should see the following details:
The bottle siphon must additionally contain O-ring from rubber.
The entire preparation process consists in the preparation (purchase) of the following materials/tools:
If you plan to dismantle the old cast-iron siphon, a hammer, chisel, chisel will come in handy.
Note! Standard sizes sewer pipes - 32, 40, 50 mm. If you are in doubt about the choice, purchase siphons with a stepped end of the spout. You just have to try on and, if necessary, cut off the extra steps of the part and purchase a sealant. If you purchased a siphon not right size, the rubber adapter will correct the situation.
To install a new siphon, you will have to dismantle the old one.
Note! Before installing a new siphon, it is recommended to clean the inner surface sewer pipe from flying. This will prevent the formation of blockages in the system.
To dismantle the cast-iron siphon, it will have to be split with a hammer and chisel. This is quite painstaking and dangerous work. Make sure that the fragments do not injure you and do not penetrate into the sewer pipe. Remove all traces of old cement.
Step 1. We check the compatibility of the filter grate (it is recommended to purchase a stainless steel filter grate for the sink / sink) with the washbasin drain hole. If the grate size exceeds the diameter of the stamped recess of the sink, then it is recommended to install using a sealant (without a gasket). But it is much better to replace the part in the store with a suitable size.
If the size matches, install the grate on the gasket, lubricating the surface with a small layer of sealant.
We insert the fixing bolt into the filter grate, bring the docking pipe with the gasket under the drain hole, align it and fasten it with the fixing bolt to the drain hole.
Step 2
Step 3 We check the threads at the ends of the siphon body. Use a sharp knife to remove any burrs that could damage the gaskets.
Step 4. In the cuff installed in sewer pipe, insert the outlet end of the outlet pipe from the siphon. If necessary, you can install a clamp.
Step 5. We assemble the siphon (the assembly technology is described above) and fasten it with plastic fastening nuts to the docking pipe under the drain hole.
We fasten the siphon to the docking pipe under the drain hole
If the siphon is corrugated, at this stage we install the latch. We connect the outlet pipe to the outlet of the siphon and fasten it to the mounting cuff in the sewer pipe.
We connect the outlet pipe to the outlet of the siphon
Step 6. Turn on the water and check the tightness of the structure.
If you install a siphon for a double sink, then, respectively, under each drain hole of the sink, you should screw the outlet pipe and connect it to the siphon.
Branched siphons, to which washing / dishwashers are connected, are mounted in the same way, only flexible hoses from household appliances.
Concealed siphons are installed in a special niche under the sink. The siphon is connected to the sink and sewer pipe, and the outer part is hidden behind a decorative overlay plate.

Frequent blockages, slow draining of water, leaks and the penetration of sewer odors into the room - all this suggests that the kitchen sink needs urgent help. In most cases, such problems are due to poor-quality installation or breakage of the siphon. To replace it, it is not at all necessary to call the specialized specialists of the utility service, since you can install the siphon in the kitchen quite independently.
The functional purpose of siphons is, first of all, to protect against the penetration of unpleasant odors into the room from the domestic sewer system. Despite the apparent variety of models, the principle of operation of devices is almost the same. When draining used water from various sanitary appliances, part of it remains inside the siphon, forming a water plug that prevents the occurrence of extraneous odors and noise when using the sewer. Similar products represented by the following types:
The main disadvantage of the design of the first two types of siphons is the lack of revision, which greatly complicates preventive work during their maintenance during operation. Such siphons are most often used for washbasins in toilets and bathrooms. For kitchen sink more practical is the use of bottle-shaped products. Their collapsible body allows you to periodically clean the container hydraulic shutter from accumulating food debris and fatty deposits on the walls of the siphon.
The determining criterion in choosing one or another type of bottle siphons is, first of all, the design of the sink itself. It can be provided with an additional drain hole in the upper part of the side wall, which serves to prevent water from overflowing over the edge when the tank is filled to the maximum. In this case, you should pay attention to the siphons with an additional overflow pipe.
For double sinks, connection to the sewer system may include one common or two separate siphons for each tank. Such designs are distinguished by somewhat complicated communication wiring.
Installing a siphon in the kitchen makes it possible to connect a nearby dishwasher or washing machine to its drain pipe. Such additional option greatly facilitates the process of connecting household appliances to the sewer, so when choosing the right product, this point should also not be overlooked.
When choosing a siphon, the diameter of its drain pipe is of no small importance. The maximum possible hole size for a particular kitchen sink model will ensure faster draining of the utilized water and prevent frequent clogging.
The bottle siphons produced today have a fairly standard appearance and are a design consisting of several main components.
In addition, the product package includes flexible corrugated hoses, gaskets for union nuts and several metal screws for fastening.
The vast majority of these products are made from plastic. Therefore, before changing the siphon in the kitchen, you should make sure that all its nodes are intact. First of all, the body of the product should not have hidden cracks. This can be easily checked by pouring some water into its container. Also, attention should be paid to the notch of the thread of plastic parts, its relief, the absence of visible dents and burrs.
Installing or replacing a siphon in the kitchen provides for some additional materials and tools needed for the job. In most cases, they are always at hand at the home master:
Despite the almost complete lack of water pressure in the drain system of the kitchen sink, many experts, however, strongly advise the use of a water-resistant sealant specifically designed for the production plumbing work. The composition must be treated with all threaded connections of the product, as well as installed gaskets.
The application of the sealant is prerequisite for a quality siphon assembly!
It is required to assemble in exact accordance and in the strictly specified order, determined by the attached instructions. In doing so, you must adhere to the following recommendations:
To check the build quality of the siphon for leakage, you need to pour into it a small amount of water. In the absence of smudges on the bottom cover, you can safely proceed with its installation.
In cases of replacement earlier installed product, it will require its preliminary dismantling. Before you disassemble the siphon in the kitchen, you need to put some kind of container under the sink to drain the remaining water. Then, using a screwdriver, unscrew the fixing screw holding the decorative drain grille at the bottom of the sink. After disconnecting the outlet from the sewer, the siphon can be permanently removed.
To install a new device, the old seat kitchen sink must be thoroughly cleaned of dirt and grease. It will also be necessary to check the condition of the rubber sealing sleeve on the socket outlet of the sewer system, which, nevertheless, is recommended to be replaced with a new sleeve. At the same time, preventive cleaning of the sewer bed itself will not be superfluous.
Installation of the assembled siphon is carried out in the following sequence:
Upon completion of installation, an initial check is carried out. assembled structure by filling the kitchen sink with water.
If the siphon has additional outlets for connecting household appliances, they must first be closed with special plugs!
If there are no leaks, proceed to connect the drain hoses of the washing machine or dishwasher, after which the installation of the siphon can be considered complete.
The operation of gravity sewers requires compliance with certain rules. When wondering how to properly install a siphon in the kitchen, you should take into account some of the nuances that are well known to professionals:
In conclusion, it remains to add that proper care and regular preventive cleaning of the siphon from accumulated contaminants will significantly extend its service life and eliminate discomfort when using the kitchen sink.

Siphon performs important features: thanks to the water stopper, it does not allow odors from the sewerage to enter the room and protects pipes from frequent blockages. If drain system worn out or out of order, its replacement does not need to be postponed until later. It is not difficult to change the siphon under the sink on your own, it does not require special skills and complex tools, the main thing is to know how to do it correctly.
Before replacing the siphon, you will have to select and purchase a new product. First, let's get acquainted with the varieties of this device.
According to the principle of operation, the siphons used in the sink in the kitchen or in the washbasin in the bathroom are divided into the following:
Previously, drain devices were made of steel and cast iron, but now practical and inexpensive plastic is most often used for siphons and other plumbing equipment. It is not subject to corrosion, does not rot and does not retain dirt. Plastic tolerates cleaning with the use of a cable and chemicals.
The cheapest products are made of polyethylene and PVC, their service life does not exceed 6 years. Siphons made of polypropylene and ABS plastic will live for more than 10 years.
The product is designed simply, and it is easy to disassemble it to check the absence of defects. It must be free of defects on the surface and in threaded connections. Gaskets are used elastic and lubricated with silicone sealant.
To install the drain device, you need to purchase an odorless silicone sealant. Acid compounds will not work.
The process of replacing the siphon under the sink consists of the following steps:
If the drain device starts to leak, there may be several reasons for the malfunction:
For repair, it is necessary to install a container from below to drain the liquid.
Tip from a plumber: if you can't buy new gaskets, the old seals should be generously lubricated with sealant or silicone adhesive and reinstalled. You can let water in after the material has solidified. Such a connection will last for several more years.
The full use of the kitchen is impossible without a sink. This is a sanitary device consisting of two elements: a bowl and a siphon, which is directly connected to the sewer system. Properly executed installation of the structure allows you to reliably protect the apartment from unpleasant odors from the pipe, harmful bacteria and microbes, in large quantities located in waste water.
A siphon is a pipe with a bend in which water and other small particles drained into the sewer.
There are several design options:
Flask-shaped models are a prefabricated structure that can be quickly attached, without the use of special tool.
The knee design is one of the simplest among all model options, which allows you to clean the blockage or change any elements in a matter of minutes. The pipe can be bent into a U or S shape, so you can use the space with maximum efficiency.
The corrugated version has a design similar to the pipe counterpart. The difference is in the use of a corrugated hose, which gives it the ability to bend in any direction. But there is one significant drawback, the corrugated tube quickly becomes clogged, as a result of which you have to disassemble and clean it more often. Even a person can connect and remove such a siphon without the use of special tools and plumbing knowledge.
The model is a hidden siphon, mounted in a wall or a structure in the kitchen. It will not be visible from the side, which allows you not to spoil your appearance big picture. It is advisable to use this option in small kitchens.
To fulfill correct connection Each set comes with a diagram, the main thing is to follow some rules
The next step is to connect to the sink, which is also quite simple.
After completion of the work, it is necessary to carry out tests to make sure that the design is working and that there are no leaks. To do this, just turn on the water and make sure that all the elements are connected tightly. By pulling elements established design the leak is eliminated. Sometimes water runs through in connection with the sink, so it is necessary to correct the seal, which is installed with a deviation.
In addition to the installation steps for the normal model, some additional steps need to be taken. The outlet is connected to the bottom of the overflow pipe. This should be done only when connecting the sink to the siphon. After that upper part pipes are attached to the overflow hole of the sink. The work is simple and not laborious, but in the case correct installation a sink filled with water will enter the sewer through the drain.
So that after the completion of the work there are no unnecessary problems, it is necessary to do right choice, respecting simple rules how to assemble a siphon for a sink in the kitchen
It is not enough just to buy a siphon for a kitchen sink. It is important to install it correctly and for this you need to carefully study the instructions and strictly follow its recommendations. Often, inexpensive siphons are installed faster and easier than their more expensive, more complex counterparts.
The kitchen sink is the most important and obligatory element kitchen sanitary ware. It consists of several parts, which, when connected together, provide the functionality of the sink. One of the components through which water is drained is a siphon for kitchen sinks. Regardless of your appearance and size, this plumbing element is designed to perform its main function - to protect the kitchen from unpleasant odors emanating from sewer pipes. In other words, we have a typical water seal in which a curved tube is constantly filled with water. In addition, the drain for the kitchen sink prevents clogging of the sewer with solid particles that settle at the bottom of the siphon.
The materials for the manufacture of the kitchen drain device are polyethylene and polypropylene. It is from them that the vast majority of products are made. These materials have the following advantages over bronze or brass siphons:
The siphon has a branch pipe to which a corrugated or rigid drain is connected. It is better to choose a sink siphon with a large drain hole. A diameter of 40 mm will be sufficient. In contrast, the 32mm standard clogs faster, resulting in more frequent cleaning.
Important: In order to be able to connect hoses from a dishwasher or washing machine to the drain, it is recommended to choose a device that has additional outlets.
In addition to the siphon in the kitchen, you may also need it. In what situations it is necessary to buy it, you will learn from our other article.
And about how to do it yourself, there is also information on our website.
When choosing, it is also desirable to prefer a drain for a kitchen sink. with overflow. This will protect you from overflowing the sink and flooding the kitchen. If the drain hole of the sink is clogged, then the water coming from the tap will simply go into the overflow hole, and from there into the sewer.
Pictured is a siphon for kitchen sink with overflow If the kitchen uses a sink that has two drain holes, then install. Its feature is the presence of another adapter with a grate, as well as an additional pipe that combines both drain holes.
According to their design, all siphons used for kitchen sinks can be divided into several types:
Different types of siphons have different design, therefore, we will consider in detail the device of a bottle-type siphon, the most popular for installation under kitchen sinks.
Structurally, such a device consists of the following elements:
We will analyze the assembly of a kitchen drain using the example of its bottle type. The siphon for the kitchen sink is assembled in the following sequence:
The work of installing siphon equipment is usually not difficult. It can be done independently. The difference is only in the number of connections to one siphon. So, if you have a double sink or there is another additional drain, then a siphon for a kitchen sink with two bowls is installed.
On preparatory stage check whether the siphon will become under the sink in its dimensions. After that, the entrance of the sewer pipe is prepared for docking with the sink drain. If the pipe is cast iron, then a rubber plug with a hole is installed in it. plastic pipes are also connected via an o-ring.
Further installation of the siphon on the sink involves the following actions:
If a siphon is installed for a kitchen sink with an overflow, then at the stage of assembling the siphon, a few more additional steps are performed. The lower edge of the overflow pipeline is attached to the outlet pipe. Fastening is carried out according to the already familiar pattern, using a conical washer and a union nut. The connection of the overflow pipe is made during the installation of the device on the sink.
The upper edge of the overflow pipe is led to a specially cut hole in the top of the sink, with its outer side. The top edge is fastened with a screw connection on the sink side. The screw is simply screwed into the pipe with a screwdriver. Now, when a certain water level in the sink is exceeded, the water will overflow immediately into the siphon, bypassing the outlet of the sink.
Additional information on how to install a siphon in the kitchen correctly is presented in the video.
