Siphons for the sink: types, pros and cons, assembly technology

Russia, Moscow region, Moscow+79041000555

The sink is the key and most indispensable link in all kitchen equipment. The most important element during its installation is the sink siphon, which performs the function of protecting the room from unpleasant sewer "aromas" and clogging the drain with small food debris.

Varieties 

The domestic market offers a large segment of sanitary products. Products are presented by chrome, metal and plastic devices for high-quality discharge. All units can be equipped with automatic and semi-automatic systems for shutting off and supplying water. They are divided into three types.

Traditional

Standard gutter construction with ordinary rubberized or plastic plugs. All processes with spillway are carried out manually, however, such designs have advantages in the form of:

• Reliability;
• Simplicity in work;
• Longevity;
• Undemanding to the service.

Semi-automatic

Such a spillway is controlled by levers or cables, which are equipped at points located above the level of water being collected. This design of the sink siphon has its advantages in the form of:

• Controls using a remote crane;
• The plugs integrated in the drain hole.

Auto

Plumbing spillway equipped with automation. Such a siphon is combined into a single design with a filling device. The control here is due to a special valve that lowers excess fluid into the drain hole during overload. These modernized siphon devices, which bring a pleasure to the owners of the house during their operation. However, they have one minus, which is expressed in their rather considerable cost.

The most popular automatic spillways are those that have functions:

• “Click-Clack”;
• Swivel handle.

Kinds

When arranging the premises with plumbing, it is necessary to study the existing types of spillways, considering the features of each configuration. What types of sink siphons exist?

Trumpet

This sample is a pipe with some bend in which a stopper is formed. This type of siphon is very often clogged, however, thanks to thoughtful structural elements, it is perfectly disassembled and cleaned.

The pipe siphon for the sink has the advantages of:

1. Ordinary and ergonomic design.
2. Optimum cost price.
3. Large diameter passage.
4. The simplicity of the service.

Bottle

If it is necessary to install in a sink located in the bathroom, a bottle-type spillway unit is installed. This design takes up a minimum of free space and is presented in the form of a bottle with a horizontal branch. Very often in the upper part of the structure there is a secondary branch for connecting the washing machine. It has the advantages of:

1. Compact vertical options.
2. Spectacular appearance.
3. Ease of disassembly of the unit and its cleaning.

Corrugated

The most popular type of gutters, created from a plastic pipe with corrugation. The receiving outlet with a metal mesh in such an aggregate has a rubberized compactor, which organically passes into a flexible pipe. Due to the fact that the structure can be easily compressed and corrugated, this unit has the following advantages:

1. The increased ductility allows the water seal to be easily bent.
2. The ductile configuration allows a siphon to be placed under the sink, which has minimal space. Conveniently attaching it to the sink.
3. With a minimum number of joints, this type of siphon is less prone to leakage.
4. Excellent mobility regarding pipe insertion.

Dry

This type of gutters is a short sink siphon. It appeared relatively recently, but already has sufficient popularity with the consumer. With the arising option of the drying of the hydraulic lock in cases of frequent and prolonged absence from the room, a dry sink spillway is installed. A special buoy is arranged inside such an aggregate, which, if there is water in it, is located on its surface. And in case of drying out the siphon, it drops and blocks the flow of negative odors and vapors.

It has the following advantages:

1. When discharging the sewer system, a dry siphon for washing has a protective function.
2. The absence of bent pipe parts that occupy a considerable space under the kitchen sink.

Material classification

More recently, siphons for the kitchen and bathroom were made only of cast iron and brass. However, time does not stand still, and with it technology. Modern siphons are made of stabilized polypropylene, PE-RT polyethylene and high quality metal.

Metal

Chrome-plated metal locks in perfect harmony with similar elements. Therefore, a fairly good option would be to install them in the bathrooms. And expensive samples of metal aggregates will look just luxurious. It goes without saying that the price of such devices will be much higher than their polymer "brothers". However, their service life will differ much more.

The basis for the manufacture of metal siphons are high-quality alloys:

• Copper;
• Brass;
• Bronzes;
• Of stainless steel.

Such spillways are not susceptible to corrosion deformation, but are susceptible to redox reactions. Therefore, a benign metal elbow under the sink must necessarily have internal galvanic chrome plating. Such a coating will serve as an obstacle for the appearance of dirt and blockage in the hydraulic seal.

A small minus of the metal spillway is the difficulty in fitting the pipe to the required size. Indeed, for such manipulation a professional tool and experience in its use are necessary.

Plastic

The most popular among the consumer aggregates are spillways. Presented in the form of polymer connecting pipe elements. Such a siphon is quite simple to install in the kitchen or in the bathroom with your own hands. Due to its quality properties, this siphon has a number of advantages in the form of:

• Resistance to corrosion and deformation;
• Resistance to decay;
• Endurance to chemical negative influences;
• Affordable assembly even for a beginner;
• Lack of limestone deposits on the tubes;
• Small overall indicators;
• Installation in the most inaccessible locations.

What you should pay attention to when choosing

With the established criteria for choosing the necessary siphon, you first need to consider:

1. The coincidence of the calibration of the sink, washbasin and nozzle.
2. The metric characteristic of the maximum amount of liquid in the channel should be increased when connecting secondary plumbing units. In this case, the number of taps in the sewer should be added.
3. Compliance with available space. With a tiny quadrature, a compact corrugated spillway should be selected.
4. The selection of the water seal must be in accordance with the design of the sink.
5. Thoroughly check the device for nicks and defective punctures.

Particular attention when buying a siphon should be given to its execution. Photos of chrome, metal and polymer spillway samples can be viewed on the pages of online stores in Moscow. You can buy high-quality goods at the price of the manufacturer and significantly save your strength and money without even leaving their house.

Assembly technology

Mounting the selected model of the hydraulic seal must be carried out strictly according to the instructions from the manufacturer. Conduct preparatory work:

• Elimination of the old siphon;
• Cleaning from the accumulation of sewer drainage.

Next, proceed to the following actions:

1. At the bottom of the sink, fix the sublattice, fixing it securely with a nut.
2. Attach a rubberized sealing ring to the tap element and press it against the hole inside the sink.
3. Assemble the key spillway structure and bring it to the drain.
4. Secure with locking hexagon.
5. Use a corrugated pipe to connect to the sewer.
6. When assembling the key spillway design, you must remember to fasten all the elements with monolithic rubber seals, which during operation will protect the unit from leaks.
7. Having put a sheet of paper under the sink, turn on the full pressure, checking the quality of installation.
8. In cases where there is a need to connect several drains to the siphon gate, the spillway is equipped with a special diffuser.

Despite the fact that this work does not seem very difficult, it still requires analytical thinking and some experience. To avoid leaks or other problems, it is better to contact a professional with experience in this field.
