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 using the device, you must connect it in such a way that the quality of the work performed does not suffer at all, and the device itself remains safe and sound.
In order for the washing machine to start working, the drain hose must be connected to the sewer. Of course, the most universal and low-cost way is to attach it to the sewer outlet. To perform such an important job, a check valve is used for the washing machine to drain. To properly install this equipment, you need to figure out what this device is, what it is for and how to properly install it.
The principle of the check valve
Most often, experts call such equipment an anti-siphon. They are made of durable plastic or stainless steel. Visually, it can be compared with a shut-off valve, in addition, the principle of operation is quite similar. At rest, the non-return valve is closed. His work begins only with the activation of the washing machine draining water program. Under her pressure, he begins to open. After the drain is complete, the non-return valve returns to its original state, thereby sealing the connection and preventing dirty water from returning to the hose.
Types and features of operation
As technological developments do not stand still and equipment continues to develop, a huge number of various types of check valves appeared on the market. The main differences are in the type of operation, the complexity of the installation, as well as in their structure. To date, the most popular varieties of antisiphon are:
- The antisiphon is folding. A large number of people prefer to use it, because if necessary or malfunctioning, the valve can be removed, disassembled, eliminated, and continued to operate.
- The anti-siphon is not separable. It is considered the most budget option. It features a single design. As a rule, such a non-return valve for a washing machine to drain is made of durable plastic, which also reduces its cost in the market, unlike the metal version.
- Mortise antisiphon. From the name it already becomes clear that this variety can be mounted in the pipe itself.
- Washing anti-siphon. Most often purchased for the kitchen space. Controls the operation of the kitchen sink.
- Wall-mounted check valve on the washing machine. Unlike all of the above, it requires considerable financial costs. Fastens, as a rule, on a wall. It is made of the most durable and stainless metal.
Operational Features
Recently, a number of companies that are engaged in the production of such household appliances have begun to include a check valve for draining as a necessary part of the kit. However, in most cases, consumers have to separately purchase such equipment for connecting a washing machine.
Of course, you can do without an anti-siphon and insert the hose directly into the sewer through an adapter. But in this case, it is necessary to observe a certain height of the connection of the drain hose to the sewer. Otherwise, not all dirty water will go into the sewer, its remnants will fall back into the laundry tank. A so-called siphon effect will occur. If for installation use the non-return valve for the washing machine to drain, 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 during operation must be replaced. As a rule, this happens every few years, but still, the service life largely depends on what material the part is made of. Therefore, you should not both choose the cheapest option, and splurge on the acquisition of the most expensive equipment. Even if the antisiphon is made of the highest quality material, it will still fail during operation under the influence of hard water.
Antisiphon Installation
You can install the check valve for the washing machine on the drain yourself, without special skills and experience. This is not difficult, since you can use an already prepared guide as an additional aid.
Despite the fact that there are several types of antisiphons, their design is similar. As a rule, 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. So that in the future, neighbors do not run home and complain about possible leaks, it is better to seal the entire structure.
How to choose the right part?
Specialists in the field of plumbing service argue that not every selected check valve on the drain hose of the washing machine can fit a specific model of the device. Therefore, it is best to go straight to the service center and take the advice of a specialist who, according to the model of the washing machine, will be able to determine which antisiphon will cope with the tasks as much as possible.
Are there any analogues?
Many are interested in the question of whether there is any other device that could fulfill the functions of an anti-siphon. Unfortunately, an analogue option does not exist today. If you do not use a check valve to drain the water, then in this case, you must change the connection plan of the washing machine. And it’s better not to do this on your own, but to turn to a plumber. Only he knows what standard rules and conditions will need to be met so that the washing machine functions properly and that dirty water does not pour back into the tank.
