Why do I need a siphon under the sink in the bathroom and in the kitchen?

No sewerage system can work without the main element - the reception of wastewater. The people call a set of pipes, bent pipes and other components of the drain valves called an ordinary siphon. You can install it without calling the plumber, The main thing is to properly assemble the structure and seal the joints.

Varieties of siphon designs

Most often, manufacturers choose polypropylene (durable plastic that can withstand extremely low or high temperatures) or metal. If we talk about design, today the market offers hundreds of models that will suit a certain style of not only the sink itself, but also the room.

As an example, we can highlight several relevant areas:

• corrugated devices - the model is extremely simple, there is a corrugated pipe with a special bend in the set, an outlet with an adapter is attached to the drain part, which provides sealing. Most importantly, this type is installed in a confined space because of its compact volume;

• bottle counterparts - those who still lived during the Soviet Union will immediately remember the main characteristics of this type. Modern systems already come with a special siphon. Now there will be no problems with cleaning, since it is enough to simply unscrew the bowl, rinse it and put it back. Installation will not take more than 5 minutes;
• pipe system - not suitable for the kitchen, mainly installed in the bathroom. It looks like a curved pipe that creates a water block. In case of blockage, experts recommend simply removing the knee and flushing. The siphon is very small, additionally equipped with overflow for the sink.

Important! The pipe system is not installed in the kitchen, because of the size of the siphon, citizens often face clogging.

The principle of operation of the device

For those who are familiar with the basics of physics, the operation of an ordinary siphon does not seem fantastic. is he needed to drain water from the sink to the sewer. If you just put a single pipe for the drain, then you can encounter a huge number of problems. For example, the general sewage system will be clogged up regularly, as food residues, small items, etc., will simply get stuck. As practice has shown, the inhabitants of the first floors suffer from this.

For familiarization, there are several tasks that only a high-quality siphon can solve:

• clogging protection. Large particles that managed to break through the mesh in the sink fall into the bowl, where they settle;
• ensuring high-quality water passage. If you simply hold a single pipe, then the remains of fat and slag will settle on the walls. Within a few weeks, it will be easier to dismantle and discard than to clean. The siphon provides a flow that does not allow particles to remain on the walls, creating the so-called “suction effect”;
• the most important task is hydrozator. It provides obstruction to gas and unpleasant odors into the room through the opening of the sink. This is achieved with the help of simple physics - the difference in the height of the nozzle and the bottom.

In simple words special bowl and the difference between the height of the nozzle forms a small accumulation of water. Experts call this "water congestion." It stops the entry of unpleasant air beyond the siphon, forming a protective “plug”. Regardless of the design model, all operate on a single principle.

Functions of drain valves

Its main function is filtering large residues. Rough "filtering" catches large pieces of food and large particles in the form of stones and other deposits.

The second task is “transportation "runoff to the sewer. Additionally, there is a lack of air, which often negatively affects tightness.

Manufacturers additionally equip drain valves removable trash screen, which is very convenient for the hostesses, or with a special overflow so that the sink does not fill to the brim.

Mounting Features

The easiest option is purchase immediately one-piece siphon kit. The kit already includes seals and all the necessary elements for assembly. Before you buy it, you need to decide on the location. For the kitchen, it is advisable to choose a large bowl, since the remnants of food easily clog a small design, which leads to leakage.

Specialists identify several fundamental rules for installation:

• the seal must fit evenly on all parts of the siphon. If there is a deviation, this will violate the tightness. During the test descent, it will not appear, but after a long washing the dishes below will be wet;
• use of plumbing tape. Many manufacturers claim: the gaskets and the thread itself will be enough to avoid leakage. But this is far from the case. Each time when it is necessary to connect several parts of the siphon, it is advisable to additionally use a tape. Any plastic, when heated, tends to expand, and the appearance of gaps is inevitable.

Compliance with even these simple rules will help to correctly install the siphon. As practice shows, only a screwdriver is required for installation, with which a grid is installed inside the sink. Many kits have detailed installation instructions.
