Bathroom sink siphon: how to choose and install

Having decided to replace the plumbing in the house or install a new one, everyone begins to study the bathtubs, wash basins, faucets and no one recalls the details on which the quality work of all this depends equipment. A mandatory element of most plumbing fixtures are siphons. It is to them the tenants of the apartments should be thankful that the unpleasant smell of sewage coming from the sewer pipes does not get into the room. In addition, the water plug inside these devices is a barrier that isolates sewer pipes from blockages. However, choosing a siphon for a sink in a bathroom, it is necessary to consider not only its technical characteristics, but also appearance.

Accommodation options

In a familiar vision siphon - This is a nondescript item hidden under a sink in the kitchen. He is remembered only if the water flowing from the faucet into the sink has ceased to leave it or is leaving too slowly. Then they unscrew it, clean it, put it in place and again forget about it for a long time.

It is more difficult to hide the siphon in the bathroom, because the bathrooms of the city apartments are so small that there is nowhere to install unnecessary structures, for example, a washbasin cabinet. But you can find an exquisitely designed designer siphon, which not only does not spoil the look of the room, but also decorates it.

The siphon is a part without which the bathroom cannot exist. But before proceeding with the choice of this miracle, which has come down to us since the time of the Roman Empire, you need to study what it can be.

Design features of different types of siphons

The simplest design is a pipe siphon. This is a curved pipe in the shape of the symbol "S" or "U", which can be collapsible and not collapsible. Its advantage is the need for precise alignment with the inlet to the sewer, resulting in a rigid drain system.

Classic of the twentieth century - bottle siphon. It is well known for its simplicity and ease of use and has the following features:

• takes up relatively little space under the sink;
• connection to the sewer pipe can be made both direct and flexible pipe;
• it is easy to disassemble during cleaning;
• To flush and remove sediment, just unscrew the bottom of the tank;
• ideally protects sewer pipes from pollution.

A miracle of the late 90s of the last century - corrugated siphon - became fashionable along with interest in the redevelopment of apartments. This type of design has its advantages:

• makes it possible to connect non-standard located sinks to the sewage system;
• very easy to install;
• By bending the tube, you can form any slope and create a water seal.

Hidden siphons have been used relatively recently. They entered the apartments along with integrated sewage systems. This is the same bottle device, but hidden behind a partition and ennobled by an external stainless steel pipe.

A novelty of the domestic market is a dry siphon, which functions not due to the creation of a water plug, but thanks to a special membrane. When water arrives, it opens and releases water, and then it is compressed again, tightly closing the flow hole, and not letting water and smells back in.

Individual varieties

In addition to structural features of the structure, siphons differ in appearance and method of application:

1. If there is no place under the sink for a regular drain device or if it needs to be installed under the bath, then a flat siphon can be used. It is convenient for installation, takes up little space, perfectly retains odors, but it has one drawback: in case of blockage, you will have to disassemble the entire structure.
2. Due to the increase in the number of household appliances, siphons for sinks with two or even three separate side fittings began to be produced. Thanks to them, it is possible to connect a washing machine and a dishwasher at the same time to a single drain.
3. Complex kitchen appliances are made for kitchen sinks, combining two or more nozzles for connecting to sinks with several sections.

How to choose a siphon

Siphon is a product that is made of different materials:

• cast iron;
• nickel;
• bronze;
• stainless steel;
• brass;
• plastic and many others.

You can choose any of them. Central to this issue is the design of the room. If the bathroom is modernized and plumbing is installed with taps and flush buttons made of chromed metal, then the plain appearance of a plastic product will spoil the whole picture.

Better pick up metal siphon in tone to the mixer on a sink - with classical steel gloss, under gold or bronze. It will look aesthetically pleasing and will retain its appearance for a long time.

At the same time, installing a plastic device under the sink will prevent regular cleaning of lime deposits, which will constantly settle on the metal.

When choosing a design, you need to pay attention to the following:

• What kind of washstand will stand in the bathroom. If it is with a pedestal or pedestal, then the appearance of the siphon does not play any role. But if the drain device will be under the sink in the open state, then it is better to take care of its design.

• Be sure to make sure that the sink neck is the same diameter as the siphon.
• If it is planned to put a washing machine in the room, then you need to take care of the pipe to connect it to the sewer.
• If a pipe siphon is taken for a sink in the bathroom, then a thorough measurement and calculation of all distances will be required.
• The diameter of the entrance to the sewer is usually standard on all products, but there are exceptions when buying a sample of foreign production. Therefore, before purchasing, it is better to compare the diameters.

When choosing, you can give preference to any model of the device, since there is nothing complicated in their structure and therefore there is no fundamental difference, except in price.

Installation of different types of siphons

Installation or replacement of the siphon for the sink is not difficult even for beginners. Of the tools and materials, except for the culprit of the work, it is required:

1. Silicone sealant.
2. Rubber coupling adapter.
3. Sealing tape.
4. Phillips screwdriver.

The surface of the sink and gaskets must be degreased with any detergent that is used for dishes, so that their surfaces get a closer contact, and there will be no smudges in the future.

Installation Order:

• We put a gasket on the hole in the sink.
• Insert the drain socket.
• From below under the sink on the socket we put on the second rubber gasket.
• We connect the entire structure with a plastic nut.

The second mounting option is for other designs:

• Put the gasket in the sink.
• Put a metal grill on top.
• We insert the long screw included in the kit.
• Below we bring the siphon, and connect the structure with a screw.

There are other, more complex designs, but their installation requires some experience and skill.

Before buying a siphon, you need to make sure that its capacity will correspond to the amount of water drained. Therefore, a siphon with a small cross-section will not fit every sink.
