Bath water not leaving? We analyze the reasons.

Many people are faced with a situation where water from the bathroom "leaves" badly. There are several reasons for this problem. Let's sort them out in order.

Clogged drainage system.

In this case, there are several ways to fix the problem, depending on the type of blockage.

• Chemical method. Thanks to the use of special chemicals, biological blockages can be eliminated. contained therein acids and alkalis are capable of corroding the bonds between particles of biological deposits, which are subsequently easily washed off with water under pressure.
• Hydraulic method. If chemical cleaning did not help, we try to remove the blockage with a plunger. The plunger allows you to clean the system by alternately creating a vacuum - excess pressure by a compressible rubber valve.
• Mechanical method. Various hooks, ruffs or steel cables are used. In the latter case, it is advisable to partially disassemble the system so as not to damage the corrugation.

Ways to prevent blockages:

• Replacing the cast-iron sewage system with a plastic one.
• Water pipe protection with filters.
• The use of siphons with built-in grids.
• Periodic cleaning with a plunger.
• Monthly preventive spillage of hot water (50 - 60˚C).
• At the first signs of clogging, a reagent is poured (fall asleep), for example: "Mole", "Tiret", "Domestos" and other analogues.

Insufficient slope of the outlet pipe in the drain system.

Sometimes the water from the bath is poorly drained due to the small slope of the outlet pipe (or pipe system). The water simply does not reach the sewer bell. To increase the slope of the passage of the drain pipe, the bell of the sewer riser is lowered or the bathtub is raised.
It is advisable to adhere to the standard maximum slope, which is 15%.

Errors in the installation of the sewer network.

Perhaps the problem is technical errors. It is necessary to rework the network with observance of slopes, optimal passes, smooth transitions, turns, installation of revisions. For example, we replace the corrugated bends with one-piece ones, install a fan valve to stabilize the pressure, etc.
