Siphon for the sink is the element of sanitary ware, by means of which the plumbing of the plumbing device is connected to the common sewerage system. In addition, the siphon for the sink:
- Creates a reliable barrier for the penetration of unpleasant odors from the sewage system;
- Prevents the formation of blockages;
- Facilitates the cleaning of sewer pipes.
What is a siphon
Siphon - a kind of curved tube with knees of different lengths, working on the principle of communicating vessels. It consists of three main components.
- Receiving tube, equipped with decorative grid or grille.
- The main body of the siphon.
- Drain connection for connection to the sewage system.
His work is as follows. Immediately under the sink is a suction pipe, through which water enters the siphon. Here, water passes through the drain pipe, and then goes into the sewer. However, due to the design features of the device, part of the water always remains in its bend. In this zone a water gate is created, which prevents penetration of sewage smells through the interior of the room.
What are siphons
The modern market of sanitary fittings offers a huge selection of siphons for sinks. To properly choose the necessary model, you need to understand the intricacies of their performance characteristics, design features, materials of manufacture and installation principles.
Material of manufacture
Siphons for the sink can be made from various materials and be:
- Brass;
- Bronze;
- Made of stainless steel;
- Cast iron;
- Plastic.
In Soviet times, when installing the sewage system, iron fittings were used, they were difficult to clean and install. With the advent of plastic, cast-iron elements have lost their relevance. Today, metal analogs are more often used in a refined design, where the shells are not covered with decorative panels.
The most popular and popular in recent years are plastic siphons made of polyethylene or polypropylene due to its low cost and easy installation. In addition, they:
- Do not rot;
- Do not corrode;
- Do not delay the internal surface of grease and dirt.
Varieties
Under the sink can be installed various types of siphons, which are structurally subdivided into such basic types:
Corrugated
Such models are the simplest, since they represent a corrugated tube, which during installation can be bent in any convenient place to create a water seal. This bend is fixed with a clamp made of plastic.
Such elements of the sanitary fixture can be stretched in case of dismantling the shell and transferring it to another location. However, the inner surface of the corrugated tube is often clogged with dirt, hair, small debris and soap flakes.
Tubular
These models have a rigid construction and are a tube of plastic or metal, which is an intermediate element between the drain of the shell and the socket of the sewer pipe.
The disadvantage of such products is a small hydraulic shutter, which, with a rare use of a plumbing fixture, often dries up and allows the sewage gases to enter the room.
Bottles
These models look like a bottle. Inside, there is a flask with a sump. The discharge of sewage from the siphon is at the level of the middle of the flask, which enables water to keep the water seal for a long time in working order and not dry out.
Conclusion
Practically all siphons for sinks are manufactured by manufacturers under standard sizes. In the case of connecting to them an additional drain, when choosing this plumbing fixture, one must take into account its throughput.
Before buying a siphon, it is advisable to check the completeness and quality of its components, so that during operation there are no unpleasant problems with leaks.
