Do-it-yourself siphon installation

Even a beginner can cope with the installation of a siphon under a sink or bathroom without resorting to the help of a plumber. The designs of modern siphons are in most cases assembled by hand, in rare situations you will need to use a screwdriver.

Consider the functional features of different types of siphons, we will give recommendations for choosing a bundle between a washbasin and a sewer pipe. In addition, we will describe step by step how to properly install the siphon under the sink, bathtub and washing machine..

Siphon device

The siphon is the connecting element between the sewer system and the washbasin. The device removes water, blocks the entry of unpleasant odors into the room and prevents the pipeline from clogging. As a rule, the siphon is mounted near a plumbing fixture (sink, sink, bathtub or washing machine) directly near the entrance to the sewer.

The standard equipment of the siphon includes the following elements:

The kit includes an instruction with a detailed description of how to install the siphon. The assembly and installation process should be started only after reading it..

Varieties of siphons for the kitchen and bath: features of choice

There are several types of these plumbing devices. The models differ in design features, material of manufacture and appearance. To make it easier to make the right choice, you need to figure out the options for the design solutions of the siphon.

Pipe. Usually mounted under the bathroom sink. It is not recommended to use such a siphon in the kitchen, as it will have to be cleaned very often. The plus of the pipe model is its compactness and attractiveness. Outwardly, they resemble a curved pipe – this bend creates a water seal.

As a rule, the lower knee of this model is removed for cleaning. The disadvantage of the pipe siphon is that the water seal is not deep enough, because of which the water evaporates faster and provokes the appearance of a specific odor.

Bottled is the most common option. Rigid flask or bottle-shaped construction. Siphons of this type have a number of positive qualities:

  • the part, which is usually clogged due to poor-quality water or merging waste, can be easily unscrewed;
  • the siphon is easy to maintain;
  • long service life;
  • water never completely leaves the water seal, so the “bottle” design reliably retains odors;
  • the siphon is equipped with an overflow – if the pipes are clogged, the water will not rise beyond the limits regulated by the system and will not flood the room;
  • if small valuables get into the sink, they will remain in the tank – you can get them by unscrewing the bottom of the siphon.

The bottle model also has some disadvantages:

  • mounted only with standard sewer pipes, since the device has a rigid structure;
  • takes up a lot of space under the washbasin.

The corrugated siphon is easy to install. The device consists of a release and a corrugated tube on a curved frame.

Advantages of corrugated models:

  • the ability to connect to a sewer pipeline placed in a non-standard way;
  • ease of installation and “moderate” pricing policy;
  • considered the most economical option;
  • the installer independently forms a bend for the water plug, which prevents unpleasant odors from entering the room through the sink;
  • the risk of leakage is minimal, since the pipe does not have any connections;
  • ensures high-quality drainage regardless of the distance between the floor and the washbasin.

Disadvantages of corrugated siphons:

  • rapid accumulation of deposits on the inner surface of the pipe;
  • the corrugated pipe loses its strength over time due to hot water – you cannot drain boiling water into a sink with such a siphon.

When choosing a siphon, you should follow some tips:

How to install a siphon in the kitchen: procedure

Preparatory work

After purchasing the siphon, you need to check its completeness – whether all parts are available. Plastic models are sold in soft packaging, so some items may be scratched or deformed during transportation. There should be no damage or burrs on the thread..

In addition to the siphon itself, you will need for installation:

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

Before installing the siphon on the sink in the bathroom or kitchen, you will need to dismantle the old device:

When replacing old cast-iron communications firmly embedded in cement, some difficulties may arise. Cast iron will have to be knocked out of the cement, but this must be done very carefully so that the debris does not fall into the pipe. Otherwise, the pipeline will be regularly contaminated. Fragments trapped in the pipe must be removed with pliers.

How to install a sink siphon. Step-by-step instruction

If the siphon was sold assembled, then it should be disassembled and checked how well all the parts are fixed and tightened..

Advice. Kitchen siphons must be assembled by hand in order not to damage the product and to control the clamping force.

Installation sequence:

Advice. It is important to ensure that the drain hose from the siphon is not twisted or kinked anywhere. Water must drain freely.

How to properly install a siphon on a bathtub

Typically, a bathtub has a pair of holes. One is located on the bottom, the other on the front wall. From these features, the design of the bath siphon is determined, consisting of the following parts:

  • plastic tube corrugation;
  • drain bowl;
  • elbow with pipe.

Siphon cleaning and repair

If the siphon is clogged and the water does not pass through the drain, then you can try to clean it in one of the following ways:

If the siphon leaks, then it is necessary:

The durability of the siphon operation largely depends on the quality of the device itself and the accuracy of its installation..
