Check valve for washing machine for draining water

As a rule, most people buying a washing machine are sure that this is the main goal achieved. However, do not forget that before you start to operate the device, it must be connected in such a way that the quality of the work performed does not suffer at all, and the device itself remained intact and intact.

To start the washing machine, the drain hose must be connected to the sewer. Of course, the most universal and low-cost way is to join the sewer. To perform such an important job, a check valve is used for the washing machine on the sink. To properly perform the installation of this equipment, it is necessary to understand what this device represents, what it is needed for and how to properly mount it.

Principle of operation of the non-return valve

Most experts call such equipment an anti-siphon. It is made of durable plastic or stainless steel. Visually, it can be compared with a shut-off valve, in addition, the principle of functioning is quite similar to them. At rest the check valve is closed. His work begins only when the washing machine's program of draining the water is activated. Under its pressure, it begins to open. After completion of the drain, the check valve returns to its original state, thereby sealing the connection and preventing the dirty water from returning to the hose.

Types and features of operation

Since technological developments do not stand still and the technology continues to develop, a large number of different types of check valves have appeared on the market. The main differences are in the type of operation, the complexity of the installation, and also in their structure. To date, the most popular varieties of antisiphon are:

1. Antisiphon folding. He prefers to use a large number of people, because if necessary or a malfunction, the valve can be removed, disassembled, eliminated and maintained.
2. Anti-siphon indiscriminate. It is considered the most budget option. It differs in a single design. Typically, such a check valve for the washing machine on the sink is made of durable plastic, which also reduces its cost in the market, in contrast to the metal version.
3. Mortise antisiphon. From the name it already becomes clear that this variety can be mounted in the pipe itself.
4. Washing anti-siphon. Most often it is purchased for kitchen space. Controls the work of the kitchen sink.
5. Wall check valve on the washing machine. Unlike all of the above, it requires considerable financial costs. Mounted, as a rule, on the wall. Made of the most durable and rustproof metal.

Features of operation

Recently, a number of companies that are engaged in the production of such household appliances, began to include a check valve on the sink as a necessary part, included in the kit. However, in most cases, consumers have to separately purchase such equipment to connect the washing machine.

Of course, you can do without antisiphon and insert the hose directly into the drain through the adapter. But in this case it is necessary to observe a certain height of the connection of the drain hose to the sewage system. Otherwise, not all dirty water will go into the sewer, its remains will fall back into the tank with laundry. There will be a so-called siphon effect. If you use a check valve for the washing machine on the drain for installation, you do not have to worry about other technical characteristics. It will prevent the return of dirty water.

When buying and installing, it is also worth considering the fact that the antisiphon is to be replaced in the process of operation. As a rule, this happens every few years, but all the same, the lifetime of a lot depends on the material of the part. Therefore, it is not necessary to choose the cheapest option, and to be ruined for the purchase of the most expensive equipment. Even if antisiphon is made of the highest quality material, in the process of operation under the influence of hard water it will still fail.

Anti-siphon installation

Mount the check valve for the washing machine on the sink can be independently, without special skills and experience. In this there is nothing complicated, since you can use as an additional help already ready-made manual.

Despite the fact that there are several types of antisiphon, their design is similar. Typically, this is a through tube with holes at both ends. One hole is necessary in order to connect it to the sewer pipe, and the other end is connected to the drain hose of the washing machine. That in the future the neighbors did not resort to their homes and did not complain about possible stalks, the whole construction should be treated with sealant.

How to choose the right part?

Specialists in the field of sanitary services claim that not every selected check valve on the drain hose of the washing machine can approach a certain model of the device. Therefore, it is best to go straight to the service center and use the advice of a specialist who, according to the model of the washing machine, will be able to determine which antisiphon maximally will cope with the tasks.

Are there analogs?

Many are interested in the question of whether there is any other device that could perform the functions of antisiphon. Unfortunately, there is no analog version for today. If you do not use the non-return valve on the water drain, then in this case you need to change the plan for connecting the washing machine. And it is better not to do it yourself, but to consult a plumber. Only he knows what standard rules and conditions must be met in order for the washing machine to function properly, and the dirty water does not pour back into the tank.
