The device of a modern siphon for a bowl

A siphon for a sink is a simple device. It provides 3 nodes:

  • siphon;
  • reception tube with a metal grill;
  • A branch pipe drain connecting to the sewage system.

Its functioning is based on the law of communicating vessels, represented by the bend of a siphon, above which there is an opening of a branch pipe receiving water, and below it there is an opening of a branch pipe for draining water into the sewage system.

Principle of operation

Closing the crane helps stop the water supply. It does not overcome the bend in the knee of the siphon, so it always remains filled. A shutter with a liquid formed in a bend prevents the gases from entering the room from entering the room. The duration of operation, the amount of time and effort spent on assembling and installing the device depend on the following factors:

  • the quality of the materials used;
  • construction;
  • quality of production.

Experts recommend that you first familiarize yourself with the types of sanitary engineering for the bath, the ways of their installation and the nuances of the assembly. Manufacturers offer a wide choice of siphons for a bath or kitchen, which are made of plastic and metal. Designs made of polyethylene or polypropylene are in great demand when equipping plumbing fixtures in the house and apartment. Experts consider their advantages:

  • simple installation (without tools);
  • low cost;
  • are not susceptible to rotting or corrosion;
  • Do not delay the mass of fat or dirt.

Metal analogues are made of bronze, brass and stainless steel. Previously produced an economical version of cast iron, but it required constant cleaning and complex installation. The appearance of plastic analogs forced out cast iron devices from the market. Metal products have a refined design that allows them to be used if the washbasins are not closed by the panel at the bottom.


Types of siphons

Types of siphons.

Siphons are of the following types:

  1. Bottle.
  2. With the presence of overflow.
  3. Flat.
  4. Tubular.
  5. Corrugated.
  6. Double or triple (for double washes, connection of washing and dishwasher).
  7. Hidden.

To the bottle siphon it is easy to connect the drain hose from the washing machine or dishwasher. The absence of special holes in them provides the possibility of attaching an adapter, which is installed between the bottle and the nozzle for receiving water.

The disadvantage of this design is the rigidity of the parts, they do not bend during the installation process. Clean the siphon for the sink simply. The lower part of the bottle of the screw is unscrewed. A disadvantage is the large number of elements that can complicate the process of installing the siphon. Experts are sure that this is not so and it is possible to assemble a similar design for a kitchen or a bath with our own hands operatively. Preliminary it is required to familiarize with its components:

  • thick rubber gasket;
  • protective grating;
  • nut;
  • receiving and drainage branch pipe;
  • стяжная пластиковая nut;
  • flat gasket;
  • plastic adapter;
  • большая резиновая flat gasket;
  • gaskets are cone-shaped;
  • plastic decorative cover.

To assemble and install the device in question for a bath or kitchen, it will be necessary to make the necessary connections with a sink, to assemble the parts, connecting them to the sewage system.

It is recommended to additionally use a special sealant for sanitary ware, if the quality of the parts does not allow them to be tightly connected with each other.

Corrugated products for sinks have the simplest design. A similar device is equipped with rubber gaskets, a metal tube, a screw, a curved frame that fixes the knee (not in all models). The inlet pipe goes into a corrugated pipe, which is connected to the sewer by means of an adapter.

The bath design in question is easy to assemble. The inlet connection is connected with a screw. Gaskets of rubber are attached from its outer and inner sides, and the end of the pipe is connected to the sewer with an adapter. To fix the joints, no sealant is required. Clogs are eliminated by pulling out the pipe and shaking out the debris from it. Then it is necessary to bend the pipe to form a knee with a shutter of water. The last element is fixed by a curved frame. Installation takes a couple of minutes.

Convenience of corrugated siphons is that they can be installed if there is not enough space under the sink. The bend in which the water shutter is formed can be modeled independently. The absence of a bent frame in the set will require calculating the radius of the bending loop. It must be sufficient to prevent the volume of water from interfering with sewage gases. The drawback of the model under consideration is that it is not possible to connect hoses to it and there is no overflow for double or triple-type washers.

Tubular structures are flat and ordinary. The first products have a U-shaped bend, it is modeled using a horizontal and two vertical pipe parts. They are used on double shells, if there is not enough space under them. They are more compact, but they are more difficult to clean because of the need to unscrew the pipe bend from the branch pipes.

In the case of conventional analogues, the tube bends in the form of a semicircle. The installation site selects a bath. They have a stylish design. The product is easy to clean when assembled. Pipe siphons have a rigid connection design, the parts do not bend for easy installation. Collect carefully, as all scratches are visible on open surfaces.

Most of the pipe structures have a small shutter. The water in it is enough to resist the sewage gases, but if you do not use the sink for several days, it evaporates. An unpleasant odor may occur. When leaving, it is recommended to close the drain hole, and after returning, let down for a few minutes with water. Such devices have a horizontal drain, so the entrance to the sewer must be at a certain height. If necessary, you can install a pipe sink with overflow.
