Check valve for washing machine: selection and installation

The quality of removal of contaminants during the washing process is depending on not only from the parameters of the washing machine and detergents, but also from competent connection. The washing unit should, along with the injection of clean water, ensure the draining into the sewage system. Mostly with injection of water difficulties does not appear. A illiterate draining device can provoke a whole complex of complications.

A contaminated liquid medium from sewer pipes has the ability to penetrate back into the tank. To block the flow of water in the opposite direction, it is required to install the check valve (anti-acid) on the washing machine drain hose.

What it is?

As already mentioned above, With an illiterate connection to the sewage, dirty water from the flow is capable of returning to the tank, which increases the cost of electrical energy and spoils underwear. Reverse (antisiform) Hydraulic valve does not prevent the planned output of used water from the tank of the washing machine. And in the case of attempting it to return from the sewer system to the tank, the damper in the valve structure is instantly blocking her road. This small component of the pipeline is suitable for any modification of the washing unit. Despite the damper, it does not interfere with the plum of water.

The quality of removal of contamination with things depends on the variety of anti-siffon and manufacturer.

Principle of operation

Scheme of the functioning of the valve is not good. It is a specific configuration of the tube in which the ball valve is a ball or spring type. This device is mounted on the siphon, the drain hose is either the sewage pipe in any place. During the work, water from the washing machine under pressure is supplied to the check valve and then merges into the sewer. When the back pressure occurs, the liquid medium does not have the ability to go back, since the mechanism of the anti-siffon does not open.

The obstacle is formed by the spring and the rubber diaphragm. Specifically, they are I Protect the drain system from the receipt of waste water. If we talk about the ball of hydroclap, the function of the defender in it performs the ball made of rubber, which is a shutter. Under the pressure of the fluid it is attached to the diaphragm, and then returns to the previous place. In purification, the ball does not need, since the mechanism itself is carried out by specialized ribs.

There are reverse hydroclap both individually and integrated into siphons for shower cabins and washes. Siphons, equipped with check valves, eliminate the penetration of liquid from shower and washing to the washing unit, in parallel excluding independent outflow of the waste liquid medium from the washing machine.

Review of species

Varieties of antisifones a lot. There are 5 main modifications of such valves. There are no significant differences in them, all devices are intended for the only task – Protect the car from returning the waste water and create conditions for the regular plum of polluted fluid.

Nevertheless, the connection of certain washing machines to the drain has its own characteristic features.

According to the design features

  • Segment (collapsible) – Metal devices consisting of several elements. This type is practical in that it is possible to disassemble and clean from various garbage and deposits.
  • Whole (untenam) – single construction made of plastic. Is the most affordable option.

By installation type

  • Warning (wall) antisifones are highlighted by a high cost. Their use is justified when the drainage system is arranged in a slight space between the walls and the outer panel of the washing machine. This type of valve valves is quite compact and will allow you to significantly save free space by adding along the wall. In addition, a stylish design of metal covered with chrome will complement the decoration of the room.
  • Cut-type valves (requiring s) – installed directly into the pipe, fragment carved out of it.
  • Washing (installed under the sink) – check valves intended for use in drain siphons washbasins and shells. They are placed under the sink, as a rule, connect with siphon sinks. They are in essence for any configuration of the siphon, do not occupy a lot of space, practical and easy to use.

How to pick up?

Specific information may be present in the instructions for individual washing machines. It is related to the selection of the check valve. In such a situation, the choice is caused by practical guidance to the car. The choice of antisifone is dictated by a certain situation. The most important thing is to make a decision in advance: where the device will be installed, what quality is water, is there enough square in place chosen for installation. The decision determines the following purchase activities.

Regardless of the brand of the washing unit (it does not matter, Bosch you, Samsung, or a different trading brand), You have the opportunity to acquire any type of valve type (but the recommendation of the service center or an experienced specialist will not be excessive). In such a situation, it is preferable to navigate to the location of the drain hose, water (contamination and rigidity), the periodicity of washing and the contamination indicator of things. When water from the water pipe is rigid, and the underwear is decently contaminated (for example, often erase overalls or children’s things), It would be nice to purchase a segment type – it can be disassembled and cleaned when clogged. With an unsubstantiated device, such a “number” will not pass, you will need to change the new, access to the place of its installation should be free.

Wall type – the pleasure is not from the cheap, but fundamentally indispensable and justified device, when the drain communication is required to be squeezed in a narrow gap (intermediates and washing machine). Often in the manufacture of chromium. Chrome details harmoniously “get along” with any tiled and plumbing devices. Polypropylene varieties are also popular.

The mortise option is suitable for a drain device directly to the sewer system. This is the easiest way to install for drain pipe, but highly reliable. The check valve under the sink is excellent combined with a siphon of any structure. Its dimensions are provided just for installation with a siphon tube. It turns out a solid protection against arbitrary drain of fluid into the sewer or its return from the drainage system into the tank. When plums in the sink, no droplet will be in a washing machine.

Just disassembled and cleaned from garbage during the need.

On a note! There is an important factor: the diameters of the washing machine hose, the sewer nozzle and the reverse hydroclap holes (the sink drain item with it) must accurately match each other. The use of adapters in this case is undesirable, as the greater the joints, the less reliable in general, the whole design (even when the sealing sealing of parts connecting parts).

How to install?

Antisifones of various modifications have the same principle of operation and installation. In order to perform the installation of a drain system with your own hands, special tools and components will be required. For installation, you need:

  • pipe cutter for metal-plastic pipes;
  • soldering iron for welding plastics;
  • siphon equipped with a specialized output designed to fix the drain hose;
  • check valve (antisifone);
  • rubber cuffs for sealing;
  • ball valve;
  • flexible hose;
  • Silicone Glue Sealant.

The installation of the drain system must be made according to the following rules.

  1. First of all it follows Disable washing machine from the mains and overlap the flow of water.
  2. Necessary Check the service life of the sewer system, Is there any obstruction, leaks.
  3. Next is worth Install anti-acid. To do this, one end to connect to the sewer pipe, and the other attach to the washing machine plum hose.
  4. Connections need treat silicone sealant and seal cuffs.

If it is not possible to establish a drain hose at the level recommended by the practical guidance, it should be connected to a specialized siphon output located in the sink, or perform an anti-siphon shutter installation. In conclusion, it must be said that there is no need for the need for an anti-siffon. Professionals advise him to establish it in the following situations:

  • When required Connect the machine directly to the sewer pipe, which is technically impossible to raise, and the insertion at the same time is too low;
  • When required Connect the drain hose to the siphon, which is under the sink.

When the drain pipe is raised to the required height and drain hose is connected according to the rules, in this case there is no need to connect an anti-siffon device.
