Siphon for sink with overflow

Buying quality sanitary equipment is a guarantee that they will serve you for a long time and will not bring any problems. Therefore, at the stage of choosing such equipment it is necessary to use as much information as possible in order to acquire exactly what is needed.

This applies not only to buying a toilet , bidet, shower cubicle or mixers. All of the above concerns the choice of a siphon for a wash basin with overflow - an object that we think about rarely, but without which the normal operation of the sewer system is simply impossible.

Features siphon washbasin with overflow

In essence, the siphon with overflow is a hydrovalve that performs three functions at once:

1. Produces the discharge of water.
2. Prevents the penetration and spreading of an unpleasant odor from the common sewage system.
3. Protects your bathroom from a possible "flood" if the water level in the bowl of the shell for any reason exceeds its volume.

So, the siphons are different in their design and material of execution. Let's look at their varieties.

The design of siphons involves the following differences:

1. Bottle siphon is the most traditional type. It is very convenient to maintain: it is easy to disassemble, takes up little space, and small items that accidentally fall into the sink remain at the bottom of the device. Bottle siphon looks like a bottle in the area of ​​the septum and is connected to a common drainage system by a pipe, straight or flexible.
2. The pipe siphon is a U-or S-shaped pipe, which can be demountable or not foldable. This is a fairly simple design, but it has some features. Thus, the diameter of the siphon inlet pipe must exactly match the size of the washbasin drain. Today, models that have a cork at the bottom of the cork are more likely to buy a pipe siphon for cleaning, if necessary.
3. The corrugated siphon is considered a separate species, although in fact it is a more modern version of a pipe siphon . It is easily connected, and since the pipe is flexible, its bend can be formed independently. This type of siphon is convenient for connecting a sink, which has a non-standard layout. Corrugated siphons are relatively cheap, but they are not disassembled and have the property of accumulating mud deposits.

With regard to such a useful additional device as overflow, it usually goes to the outlet of the sink itself (in the bathroom), and in kitchen sinks - it is connected to the siphon by an outer tube.

Also there are special models of devices - for example, a siphon with one or two overflows (for a double washbasin), with a tap for a washing or dishwasher, with a side overflow, etc.

As for the material, the siphons are plastic and metallic. The former are considered more practical because they are not susceptible to rust, corrosion and rot. Also, having a higher coefficient of expansion, they are easier to install. However, at the same time, the plastic has a lower thermal stability than the metal.

Sometimes the interior design of the bathroom puts forward certain requirements, even to such a device as a siphon for washing with overflow, and then metal models are used from cast iron and nickel, brass and various chrome alloys. They look more presentable, which is important, if the space under the washbasin is not closed by a bedside table or cabinet, and the siphon is in sight. However, metal products have their drawbacks: over time they become overgrown with a layer of oxide and dirt, and then the siphon has to be changed.
