Tubing for a bath: semi-automatic, automatic, how to choose and install a good overflow drain

strapping The strapping is called the sanitary siphon under the bathroom, through which the sewage is drained. The second name of the strapping is a drain-overflow. It has a lower and upper opening - drainage and overflow respectively.

Through the drain the water from the bathtub gets into the pipe, and the overflow is necessary in order that the water does not pour over its edges. In the siphon these holes are combined and tied. Such a system saves the bathroom from flooding. But if the intensity of water set in the bathroom is too high, even she can not help. Strapping has become popular also through the simplicity of the design and installation.

Today, a large number of types of strapping are sold, but all of them are mainly made of two materials:

1. High-strength plastic. This is the most common in private houses and apartments option. The advantage of the plastic system in its durability, because it does not lend itself to rust and destruction in wet conditions. It can be cleaned with almost any chemical, and its cost is available to every family. But the plastic overflow drain has some disadvantages. The material itself can be damaged if accidentally struck or mismanaged. The constant action of hot water leads to deformation of the pipe where it has been improperly installed.
2. Metal. The most commonly used metal is copper, bronze and brass, less often steel. But these straps have more disadvantages than advantages of use. During installation, the system must be customized to use the necessary tools. Metal pipes are much more quickly clogged, rust can appear on their surface, and some means lead to the destruction of metal.

design In order to choose the most suitable drain-overflow system for the bathroom, it is necessary to understand the design features. By this criterion, the following types of strapping are distinguished:

1. Universal. It consists of a siphon, drain and overflow receptacles, a drain pipe and a drain for a sewer pipe. The overflow is located approximately 5 cm from the edges of the bath. Outwardly it is covered with a grating, so that large objects do not fall. From the inside to the hole is connected a pouring pipe connecting it with a branch pipe. If the water level in the bathroom reaches overflow, it merges through the tube and enters the sewer system, excluding the flooding of the room.
2. Automatic. This system was first proposed by the German company Kaiser. Its difference from the universal system is only in another cork design, but the overflow system is almost the same. The plug has a special spring that opens and closes the drain automatically. The person needs to press a foot on a special lever to bring the plug into action. It is very convenient and aesthetically attractive. It is worth remembering that such a strapping has a complex design, so it is necessary to buy it only from the production of well-known firms.
3. Semi-automatic .In this system there is a similarity with the automatic. To control the strapping, a special receiver with a control unit, cork and cable is used. As a control unit, a valve or plug is used. Under it is located the overflow. When a person acts on the block, then through the cable action gets on the plug. You can not even wet your hands in the water, it's enough just to work on the block to open the hole.

The main advantage of using piping is to prevent water overflows beyond the edges of the bathroom. This system is the same, for overflow does not need a separate discharge into the sewer.

Among the advantages of automatic and semi-automatic systems can be noted ease of use. They look better than a simple overflow, you do not have to bend down to open them, but just press the lever or open the valve.

strapping The installation process depends on many factors, including the type of strapping, the material of manufacture and so on.

The standard installation procedure is divided into the following steps:

1. Dismantling the old system. Strap of plastic can not even be unscrewed, but simply broken. Dismantling the metal system may take some time. If the pipes do not unscrew, then you will have to use the bulgarian. In its operation, you must be extremely sharp, so as not to damage the bath itself.
2. A new system is being tested, namely whether all the parts for fixing to pipes are suitable, and whether there are sealing elements.
3. Detach the grilles from both holes.
4. If possible, the bathtub should be turned over to correctly install the siphon and the receiver. But if the bathroom is cast-iron, then it's rather difficult to do.
5. To the drain hole fix the grate and fasten the whole structure with a coupling bolt. Do not tighten the plastic construction very much, because it can just burst.
6. The overflow tube is mounted in the same way. The corrugation is stretched to the desired size.
7. The bundle bundle can contain 4 or 2 gaskets. In the first case, they are installed on both sides of the bathroom for draining and overflow. In the second case, they are installed from the outside to prevent leakage.

Thus, the piping( drain-overflow) is simply necessary for any bathroom. Without it, you can easily flood the entire room and neighbors from the bottom.
