When installing plumbing equipment in the kitchen or in the bathroom, the contractor must ensure the correct connection to both the water supply system and the sewage system. According to many homeowners, only experienced craftsmen know how to install a sink siphon without additional problems. But this is far from the case. Installation of this device is a fairly simple job, not associated with special difficulties, not requiring much time.

To correctly select a siphon for a sink in the bathroom or for washing in the kitchen, you need to know the features of its design and purpose.

Corrugated siphon. In appearance it resembles the previous type, but it is made of corrugated plastic flexible pipe with a connecting node. A significant advantage of a corrugated product is that it can be connected to any sink. But this plus is offset by the lack of the possibility of operation provided that boiling water is present in the device, as well as concentrated chemicals. In addition, the installation of a corrugated sink siphon is not allowed in an unheated room.

Bottle siphon. Outwardly similar to a conical or cylindrical vessel. It is made of steel, cast iron, brass, plastic or other material. On the side wall and in the upper part there are holes through which pipes are connected, the bottom of such an element is collapsible - it sits on a threaded connection. You can clean the device from blockages by unscrewing the bottom.

Siphon pipe. It is a pipe whose bend has an S- or U-shape. It is connected between the wash basin and the sewer, and waste accumulates in its lower part. Cleaning is done by disconnecting the tube, followed by flushing of its contents.

A significant disadvantage of the pipe type product is a small water seal. It can simply evaporate if the owners do not use the sink for several days. Then an unpleasant smell from the sewage system will penetrate into the room. In the kitchen, a product of this type is not recommended to be installed, since it will have to be cleaned quite often.

When installing a pipe type siphon, you should be prepared for the fact that it will often have to be cleaned

Good to know! On sale there are models of bottle siphons equipped with a corrugated nozzle. This ensures the convenience of docking with the sewer pipe.

Branched siphon. Designed to connect several inlet pipes from household appliances, sinks at the same time. It reminds the previous device, however the design is a little more complicated.

Flush mounted siphon. Of all the available, this is the most expensive model. Ideal for sinks in the kitchen or in the bathroom, mounted to the wall or mounted on an open shelf. The design of such an element of the drainage system is hidden behind a decorative screen in a small niche.

Siphon device

This product acts as a connecting element between the washbasin and the sewer system. It removes water, prevents clogging of the pipeline and blocks the entry of unpleasant odors into the room.The installation of the siphon is usually carried out near a plumbing fixture - a sink, bathtub, sink or washing machine - in the immediate vicinity of the sewer entry.

The following items are included in the standard product kit:

  • body. You can choose one of the above types;
  • exhaust pipe with rubber gasket and threaded metal insert;
  • fastening plastic nuts with a diameter of 32.50 or 40 mm;
  • cone-shaped rubber cuff, with a diameter of one of the above;
  • cuff with soft skirt. The diameter of this part must match the value of this nozzle parameter;
  • a tightening fixing screw (the best option is stainless steel), a filter overlay for draining (also stainless steel) with a gasket (oil-resistant rubber or silicone plastic);
  • rubber patch plug drain.
How to install a sink siphon

The siphon consists of several parts and its tightness and performance depend on the correct assembly

In addition, the kit includes detailed instructions on how to install a siphon on the sink. Proceed with assembly and installation only after reading it first.

Do-it-yourself siphon in the kitchen

In a modern cooking room, you can see a sink with two washing zones. In this case, the requirements for the installation of a siphon for a sink in the kitchen are the same as for a single design. The question naturally arises: maybe it is worth installing a separate drain device on each channel? This, of course, is allowed, but such a solution is irrational, since it requires more space. Its drawback will be especially noticeable when connecting additional equipment, for example, a dishwasher. The procedure for installing a double siphon has its own characteristics, but, in general, is not much different from the installation of a single structure product. Next, for ease of understanding, the installation of the latter type of device will be considered.

When purchasing a siphon, first of all, check its completeness and make sure all parts are present. Plastic models are sold in soft packaging, due to which some elements may be deformed or scratched during transportation. No burrs or damage should be present on the thread. To complete the installation of the sink siphon, you will need:

  • gasket or silicone sealant;
  • insulating tape;
  • small flat screwdriver.

If you replace old concrete cast iron pipes that are firmly concreted, you may encounter some difficulties.

Advice! Knock out cast iron from cement very carefully, preventing debris from entering the pipe. Otherwise, the pipeline will be regularly polluted. Remove splinters with pliers.

Dismantle the old siphon in the following sequence:

  • put a bucket under the sink;
  • remove the broken device and sewer;
  • replace the coupling if necessary;
  • remove dirt from the drain and socket. Fill the sewer pipe with a bag or rag.
  • installation of a new siphon. If this device was sold assembled, it should be disassembled to check how tight and tightened all the parts are. To control the clamping force and not damage the product, you must manually collect the sink siphons in the kitchen.
How to install a sink siphon

Installing a double siphon has the same principle as installing a single siphon

Installation of the prepared product is performed as follows:

  • we mount a rubber gasket on a cast-iron pipe. We bring the plastic sewer pipe to a level of no more than 40 centimeters from the floor and install on it a pre-purchased special adapter;
  • we connect the main part of the siphon and the pipe under the sink;
  • with your free hand we insert a mesh with a screw and a gasket into the drain hole, bait the screw and press it fully;
  • insert the corrugated pipe into the drain bell and tighten with the wing nut;
  • install its bell in the sewer pipe;
  • some instructions recommend connecting additional equipment at this stage. However, it is advisable to first check the siphon by connecting it to the sewer. At this time, we close the bends with plugs. They are usually included as well;
  • After checking and making sure that the siphon is working, we connect additional household appliances. We fix the drainage hoses of the dishwasher with clamps.

At the same time, it is very important to make sure that the drain hose extending from the siphon does not bend or twist anywhere. Even the smallest obstacles should be absent on the way of water flow.

Popular siphon manufacturers and how to choose

In this segment of the sanitary market, products are widely represented, both foreign and domestic manufacturers. If we talk about foreign companies, then experts recommend giving preference to siphons that came off the assembly lines of the following companies:

  • Jimtеn (Spain);
  • Geberit (Switzerland);
  • Viega (Germany).

The products of these companies are characterized by the following differences:

  • unique design solutions;
  • distinction of species in materials and construction;
  • durability and reliability;
  • high price.
How to install a sink siphon

Confidence in the tightness of siphon connections can only be achieved if you select a product from a well-known company that guarantees quality

Domestic manufacturers are represented by such enterprises:

  • Aquant
  • Orio;
  • VirPlast;
  • Aniplast.

The main advantage of domestic products is lower cost, not at the expense of high quality.

So that complaints about the operation of the purchased product do not arise, when choosing it, you must be guided by certain rules. They concern both the siphon device for the sink and the set of functions it implements. They can be summarized as follows:

  • Before you go shopping, measure the diameter of the drain hole of your plumbing equipment. In order for the joint to be airtight, a siphon with an absolutely identical inlet size should be purchased;
  • determine the need for additional functions: double entry, tap, overflow, etc .;

Advice! From the point of view of economic feasibility, it is recommended to install not several siphons, but one that has an appropriate set of functionality.

  • Choose the most suitable type of siphon. When installing a standard washbasin / sink in a room, consider its location relative to the sewer pipes. For the washbasin / sink, which were made to order, it is more advisable to purchase siphons when purchasing such plumbing equipment. Otherwise, you will certainly encounter the difficulties of separately selecting the right product;
  • One of the critical characteristics is the diameter of the sink siphon for the sink. It must correspond to the value of this parameter of the incoming sewer opening. Its standard values ​​are: 35, 40 or 50 millimeters. The installation of the siphon, the size of the outlet pipe is smaller, is carried out using additional rubber gaskets. A product with a large cross section cannot be installed;
  • aesthetic preferences are also an important factor. It is very difficult to see the siphon in the sink with a pedestal, so no serious complaints are made about its appearance. For a washbasin without a pedestal, a chromed product would be more appropriate. When installing designer plumbing, do not forget to include funds for the purchase of fittings in the cost estimate;

As for the cost, here the opinions of experts are reduced to the following thesis: from the point of view of operational characteristics, there is not much difference between expensive and cheap siphons. Elite devices with the cost of hundreds of euros and cheap siphons Aniplast and Orio perform equally well. Of course, the service life of the metal is longer, but with regard to plastic, we are not talking about one dozen years.If you need a relatively inexpensive chrome plum, check out the catalog of the aforementioned German company Viega. There you will find quite decent, including budget, models.

It is possible to call the installation of a sink siphon for a sink a difficult task. A person with only basic plumbing skills can do this. However, if you do not consider yourself a “home master”, it is better to use the services of professionals.
