S-shaped siphon. Washbasin siphon: an overview of different models. Material for the manufacture of siphons

In our homes, there are many inconspicuous devices and appliances, which are rarely remembered. In the bathroom, such a device is a siphon. Without it, even expensive plumbing equipment will be unusable. The most demanded in the Russian construction market is a double-breasted and bottle siphon for a washbasin.

They are adapted for the descent of effluents into the sewer. In parallel, they block the upward flow of gas from the general sewer system.

A siphon, in essence, is a tube or system of tubes with a bend or flask. Like other plumbing equipment, manufacturers are constantly improving washbasin siphons.

However, the configuration of siphons is quite standard:

1. Protective grill or mesh with five to six holes, the diameter of which should not exceed ten millimeters.
2. Thick rubber pads three to five millimeters thick. Please note that usually the gasket is produced in black. In more expensive models, it is white.
3. Outlet or outlet pipe with a small flange for gasket installation and two or three relief rings.

Please note that, depending on the model, the nozzle may be equipped with a branch pipe for connecting a dishwasher or washing machine.

1. Connecting screw, the diameter of which should not exceed eight millimeters.

It is better to choose a model with a stainless steel connecting screw.

1. Siphon body.
2. nuts.
3. Sewer outlets.

Material for the manufacture of siphons

The material for the manufacture of siphons must be thermally and chemically stable. Typically, washbasin siphons are made of plastic, cast iron, nickel, brass or brass-bronze alloys.

Siphons can be made from different materials

The most practical in terms of operation are plastic siphons. They do not rust, rot or corrode.

Also durable are copper alloys of brass and bronze, which are usually coated with a layer of chromium. Such siphons are not subject to corrosion, they do not rust.

However, over time, they become covered with a layer of oxide. Dirt begins to cling to the irregularities that have arisen, which becomes more and more over time. Plastic siphons are much more practical in this regard.

A plastic siphon has an undeniable advantage over a metal one. Plastic has a high coefficient of expansion, which greatly simplifies the installation process.

When installing plastic siphons, it is not required additional materials for sealing - they are replaced by a coupling.

Types of siphons

To date, there are quite a few varieties of siphons.

The main ones include:

• Bath siphonsconsisting of two pipes - drain and overflow. They are combined in front of the water seal. Further, the water goes into the sewer through one pipe.

The bathtub siphon should not be monolithic.

Its pipes should be easily adjustable in length and fit any drain hole.

• Siphons for showers have another name - "trap". It is installed in the cab tray or mounted directly on the floor.
• Washing machine siphons. The siphon is placed in a box, which is attached to the wall (behind the washing machine, above it or to the side of it).
• Siphons for the kitchen. Most often, a siphon with an overflow for a washbasin with several branches is chosen for the kitchen so that a dishwasher can be connected. Install it under the sink.
• Siphons for washbasins and sinks(corrugated, pipe and bottle).

When installing plumbing equipment, it is worth using a siphon of a suitable variety. Mounting an inappropriate device may result in equipment failure or leakage.

Corrugated siphons

The design of the corrugated siphon is the simplest. In order to form a water seal, one part of it is a bend, which is fixed with a plastic tape. The rest of it remains mobile and bends well.

Corrugated siphon

Corrugated are easy to install. The flexible frame allows it to be installed anywhere. However, its folds are quickly clogged with grease, dirt, soap waste, and it is formed. You can eliminate it with the help of chemicals or simply by disassembling the siphon.

Pipe siphons

The undeniable advantage of pipe siphons is small size, so they are ideal for installation in the small bathrooms of typical apartments.

Typically, pipe siphons are made in the form of the letter S or U. This is a bent plastic or metal tube equipped with a hatch for cleaning and draining water. Installation of siphons of this type is possible only when the space under the washbasin is large enough.

S-shaped and U-shaped siphons

Bottle siphons

Visually, a bottle siphon for a washbasin is familiar to almost everyone. This type of siphon has a rigid structure, appearance which resembles a bottle or flask. The design of such a siphon is convenient for clearing blockages, since their bottom is made to be unscrewed.

The bottle siphon retains the smell of the general sewer system due to the fact that the water does not completely leave the siphon.

Bottle siphons can be made from different materials

Often, bottle siphons are equipped with overflows. They serve to control the water in the wash basin. "Overflow" prevents water from overflowing over the edge of the washbasin.

Siphon selection

When choosing a siphon, you should be guided, and first of all, by the class of sanitary equipment. With standard parameters and characteristics for a washbasin, it is very easy to choose siphons. For a standard outlet, a standard siphon will do.

When choosing a siphon, be guided by the model of the washbasin

If it was custom-made, you should purchase a siphon along with finished product, even if its cost exceeds the cost of standard siphons.

When choosing, consider the volume of water that the siphon will pass daily.

The design of the siphon is no less important than its performance. Siphons can be narrow, wide, with a false cap or built-in stopper.

When buying, pay attention to the quality of rubber gaskets and seals - this will save you trouble during operation.

A siphon (a tube or a pump in Greek) is an indispensable element of any plumbing fixture that drains drains and prevents sewer gases from entering the room. It works on the principle of a hydraulic seal, that is, it is a channel bent in the middle down, filled with liquid at the deflection point. The water plug isolates the air environment of the room from the sewer, but does not prevent the free flow of liquid. The sink siphon differs from similar bathroom devices and shower tray only by the fact that the high location of the washbasin allows you to freely choose the dimensions of the device and the volume of water in the water seal can be quite large.

Depending on the design and shape, washbasin siphons can be divided into the following types:

• Pipe. It is a curved S or U-shaped rigid pipe, collapsible or non-collapsible. Some models have an opening plug at the bottom for easy cleaning. Pipe ones require a fairly accurate alignment of the washbasin drain hole and the sewer inlet.

Pipe U-shaped siphon - the simplest drain design

• The bottle siphon for the washbasin, as the name implies, has the shape of a bottle in the part where the water seal is located. The connection to the sewer can be made with both straight and flexible pipes. Compared to a pipe bottle design, it has significant advantages: it takes up less space; easy to understand; objects that accidentally fall into the drain are not lost, remaining at the bottom of the flask. Among the shortcomings, one can name a greater tendency to accumulate impurities at the point where the flow exits the glass into a straight section. The bottle type is the most widely used due to ease of maintenance.

Bottle siphons are the most complex in design, but the most convenient to maintain.

• Corrugated - a universal design, it is just a flexible tube. It can be bent in any configuration, which allows you to connect washbasins to the entrances to sewer system located not according to the standard. In addition, corrugated siphons are cheap and very easy to install. The slope to create a water plug is formed manually by bending the tube. Disadvantages: uneven corrugated surface tends to accumulate deposits, the pipe is not separable. On the other hand, there are no intermediate connections - less chance of leakage.

Corrugated siphon is cheap, easy to install, but has many disadvantages

• Hidden siphons are a variant of the bottle design, where there is only horizontal pipe, and the bottle (glass) itself is built into the wall. Rarely used and expensive type.

Additional functions

Plums can be supplemented with the following functions and elements:

• On the washbasin with a second, upper outlet, a siphon for a sink with an overflow is installed. This system prevents accidental flooding. In sinks, the overflow is usually located in a ceramic structure and exits directly into the outlet; in kitchen sinks it goes with an external tube into the siphon.

• An additional side entrance is equipped with siphons designed to drain both from the washbasin and from the washing machine. The outlet is installed between the neck of the sink and the water seal.

Both the overflow and the washing machine inlet are only integrated into the bottle siphons.

Sink siphon

It is structurally similar to the washbasin drain, except that the sink neck has a larger diameter, and the distance from its center to the wall is also noticeably larger. In addition, sinks often have two, sometimes three sections. Of these, one will be flat, for vegetables, and two will be of full depth, with an overflow (overflow). Plus an extra drain for dishwasher. So the siphon kitchen sink can be either very simple, single, or very complex, combining up to six drain streams.

Siphons for kitchen sinks with several bowls have a rather complex shape.

Release: in a set or separately

The outlet, which is placed on the drain neck and connected to the main part of the siphon, may be included in its kit. Regular releases are simple budget clips with bars. More aesthetic and expensive are purchased separately. Outlets with an adjustable valve that closes the drain hole are usually included in the mixer package. Quality kitchen sinks are always sold with releases.

Outlets can be equipped with simple grilles or bottom valves. Recently, push valves have become more and more popular.

Materials: plastic or metal

Siphons, depending on the material from which they are made, are divided into two types: plastic and metal.

• Plastic. The cheapest siphons are polyethylene, as a rule, they have simple design, mainly pipe, a small amount of connections. But polypropylene is used more often, the parts made of it are more rigid, keep their shape better, and connections are more reliable. Polymer siphons of complex configuration are made from this plastic. To connect washing machines, the drain of which may be at a high temperature, it is also recommended to use polypropylene, it is less susceptible to thermal expansion. After the start of operation of the washing machine in the boiling mode, the siphon often begins to leak, it is necessary to tighten all threaded connections.

A range of inexpensive polypropylene siphons, mainly bottle designs

• Metal siphons for sinks and sinks. They are more expensive than polymer ones, their service life is higher. The most commonly used copper alloys are brass and bronze. Alloys do not corrode, but oxidize, they are electroplated on the outside. Siphons are also made of stainless steel, but the cost of such products is quite high, so they are not widely used.

Designer chrome siphons are as beautiful as they are expensive

All connections, threaded or crimped, are sealed with soft rubber or rubber-polymer gaskets.

How to choose the right siphon

When choosing a siphon, the following factors are taken into account:

• Neck diameter. Wash basins and sinks are different.
• The presence of an overflow.
• The need to have an additional drain for a washing machine or dishwasher.
• The distance from the neck to the outlet of the sewer from the wall in horizontal projection. As a rule, a straight piece of pipe is enough in length, but there are exceptions.

Washbasin connection scheme, suitable in the vast majority of cases. The standard height of the sewer entrance to the wall for a washbasin is 520-550 mm, for a kitchen sink - 300-450 mm, with a grinder not higher than 400 mm

• Availability of release, often they are included in the set of sinks and faucets.
• Is the sewer outlet located opposite the siphon. If it is displaced by more than 2-4 cm, it is better to prefer a bottle siphon with a flexible pipe or a corrugated pipe.
• The diameter of the entrance to the sewer. It can be different: 35, 40 and 50 mm. It is desirable that the diameter of the siphon inlet tube correspond to this value. It may be smaller, in which case an adapter is required. But no more.
• aesthetic preferences. In a washbasin with a pedestal, the siphon is practically invisible and its appearance does not matter. A chrome-plated siphon for a sink without a pedestal would be more appropriate. For designer plumbing, you will have to fork out for fittings corresponding to it.
• Price. Hand on heart, there is not much difference between cheap and expensive siphons in terms of operation. The drain will be effectively carried out both through cheap Orio-plastic and Ani-plast siphons, and through elite devices worth hundreds of euros. Of course, metal will last longer, but for plastic we are talking about several decades. If you need a chrome-plated, but relatively inexpensive drain, you should pay attention to the German Viega siphons, the company's catalog has quite decent budget models. Ease of use largely depends on the design (easier to maintain bottled) and release (presence of a valve, if necessary).
