Check valve for washing machine for draining: for sewage, for drain hose and drainage

When you connect the washing machine to the sewer, you need to take into account a number of important nuances that will determine not only the efficiency of the drain system, but also the quality of washing. The simplest and most convenient option is to connect the drain hose directly to the sewage outlet. But for proper functioning of the drain it is required that several conditions are met( for example, the drain hose should be located at a height of not less than 50 cm from the floor level).However, these requirements do not always work, so masters have to look for other connection options.

Connecting a drain through a check valve is an excellent solution to the problem. About what this device is, what it is needed for and how to properly install it, read below.

If the drain hose is connected to the sewerage outlet in violation of sanitary standards, then it is very likely that the sewage water will return from the sewer pipe back to the drum of the washing machine. As a result, at the end of the washing you will get a stale, foul-smelling laundry. The check valve is designed to prevent such a development of events( which, by the way, is called "siphon effect").

Check valve, or anti-siphon should be installed when there is no possibility to install the drain hose at the correct height. Another case in which this device can not be dispensed with is when the connection of the washer is drained through the siphon of the shell.

You should also consider installing the antisiphon if, during washing, you notice signs of a siphon effect. These include: increased washing time, poorly spun things, increased consumption of washing water and electricity by the washing machine.

Check valve is a fairly simple device made of stainless metal or plastic. In appearance, it is a bit like a shut-off valve, and the principle of operation is similar. Antisiphon is needed in order to regulate 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 the pressure of the water. When the drain program is turned off, the valve is automatically locked, preventing the return of water.

Several types of check valves are available in the modern sanitary equipment market. They differ in the features of the design, the type of installation and the field of application.

Basic types of anti-siphons:

• demountable - a metal device consisting of several parts;this kind is convenient in that, if necessary, it can be disassembled and cleaned;
• non-separable - monolithic construction, made of plastic;is considered the most budgetary option;
• Mortise - valve, which is installed directly into the pipe, to the place of the cut from it;
• washer - a check valve intended for use in drain siphons of sinks and washbasins;
• wall - a beautiful design of chrome-plated metal, which is mounted on the wall;the most expensive option of all of the above.

• Some manufacturers of household appliances add a check valve to the basic equipment of washing machines, but so far not all do. Therefore, most likely, you will have to buy this device yourself in a specialized store.
• If you connect a drain by a non-return valve, you do not have to worry about following the recommendations regarding the height of the drain hose. The main thing is to install all the elements of the system in such a way that they are provided with a free approach in case they need cleaning or repair.
• When buying a non-return valve, be prepared to change this device every few years, as it will be exposed to hard tap water. The more quality the product, the longer it will last, but it's not worth paying too much - no matter how expensive the device is, sooner or later it will need to be replaced.

Installation of a non-return valve is not an easy task, it can be handled on its own without the help of a plumber. Complete information on the installation you can get from the instructions to the device, which must be read, we will give only brief recommendations.

Antiphones are different, but most of them have the form of a tube with two holes. One end of the device must be connected to the sewer system( by screwing it into the outlet or cutting into the pipe), and the other end should be connected to the drain hose of the washing machine. In order to eliminate leaks, treat all joints with silicone sealant for sanitary ware.

• Experts say that not all drain valve models are suitable for your washing machine. You will be able to find a suitable anti-siphon in the service center. You can also seek advice from an experienced master who specializes in repairing washing machines.
• The best recommendations have check valves from European manufacturers. A large number of positive reviews collects equipment from Italian companies Siroflex and Merloni, as well as from the Czech company Alcaplast.

Check valve for washing machine - not so rare a product, but find it in stores, especially if you live in a small city, it is not always possible. Therefore, many are interested in the question: is it possible to use something else to prevent the siphon effect?

Unfortunately, the answer to this question will be negative. Analogues antisiphon does not yet exist. In order to do without it, it will be necessary to organize the discharge in such a way that all the elements of the system are located as expected, and then there will be no siphon effect.
