However, these requirements are not always possible, so masters have to look for other connection options.
Connecting a drain through the check valve is an excellent solution to the problem. About what is a given device, for which it is necessary and how to properly install it, read below.

The check valve is designed to prevent such a development of events (which, by the way, is called "Siphone Effect").
Check valve, or antisifone should be installed when it is not possible to install a drain hose at the desired height. Another case at which without this device can not do, this is when the stroke plum connection is made through the siphon of the sink.
An anti-siffon installation should be thought about and if you notice the signs of the siphon effect during the washing. These include: an increase in washing time, poorly stressed things, the increase in the consumption of the washing machine and electricity.

Check valve is a fairly simple device made of stainless metal or plastic. In its appearance, it resembles a slightly shut-off valve, and its principle is similar. The anti-acid is needed in order to adjust the flow of water in the pipe, allowing it to move only in one direction.
Initially, the check valve is in the locked state, but when the drain mode is activated, it opens under water pressure. When the drain program is turned off, the valve is automatically locked, preventing the return of water.
