Why are they needed?

The main purpose of the device is to create an obstacle for the penetration into the apartment of unpleasant "sewer" odors. The equipment creates a water trap between the sewer system and the household appliance. In addition, the siphon for the washing machine performs the following tasks:

• Prevention of clogging of the sewage system with small particles of garbage, which are many in things loaded into the “washer”.
• Reducing the load on the pump by reducing the length of the drain hose, eliminating its kinks.

Important! Before you select all the necessary components for connection, once again weigh the pros and cons of the location of the washer. Perhaps our review will help you with this. “Where is it better to put a washing machine - in the kitchen or in the bathroom?”.

Classification

The following types of equipment are distinguished:

• Standard sink trap with drain for the washing machine. This is a device that is installed under the sink or bathtub. The device, in addition to draining from plumbing, has an additional tap for connecting household items.
• "Cuff". The device is a rubber valve that is inserted into the sewer pipe. The drain hose from the “washing machine” acts as a water seal.
• The siphon for the washing machine is external, specialized. It is installed specifically for household appliances. The downside is its large size, because of which it is impossible to move the car closer to the wall.
• Internal (hidden). A compact device that is mounted inside the wall. When using it, you can put the equipment directly near the wall.

Important! According to experts, the best option is to use a standard device with an additional tap or a compact hidden siphon for a washing machine.

Using built-in equipment allows you to move equipment from one place to another. Since the installation location of the device is decorated with a special cover, the interior will not suffer at all.

Important! A new type of siphons that are used to connect additional equipment are devices equipped with a check valve. The role of the valve is played by a ball made of plastic filled with air. The non-return valve prevents the penetration of drainage liquid into the washing machine, which allows to extend the life of the equipment.

Materials of manufacture

The following materials are used for the manufacture of siphon parts:

• Cast iron. This material is used only for standard cast iron bathtubs. It is very difficult to connect modern plumbing through this siphon.
• Brass, copper. Copper and brass hydraulic shutters - strong, durable, maintenance free, well cleaned, distinguished by aesthetic appearance. Their only drawback is the relatively high cost.
• Plastic. Of all the materials used to make siphons, this is the most popular.Widespread use due to the fact that with good strength characteristics of plastic is affordable.

Important! Did you know that the longevity of a washing machine depends a lot on the quality of the water in your plumbing system? If you understand that it leaves much to be desired, consider the installation and installation water filter in the apartment.

Connection Order

Consider how to connect the most common models of water locks to a washing machine and dishwasher.

Standard siphon for washing machine

The installation procedure is as follows:

1. Assembly of the main parts. Complete with the product there is an instruction, following which you can assemble the components into a single whole.
2. Mounting the device on a sink or washbasin. It is necessary to pre-treat the drain hole with sealant to obtain a strong joint. Fix the device with a special bolt.
3. Drain connection to the sewer pipe. To do this, just insert the drain hose into the sewer. To seal the joint, use a rubber gasket or sealant.
4. Connect the drain hose that is available on the washing machine. The connection is made using a crimp ring. Do not bend the hose. If the drain hose is not long enough, it can be extended. But this can only be done as a last resort, because the operation of the drain pump will be difficult.

Important! Before using the equipment, you should check the tightness of the joints, draw water into the machine and turn on the drain mode.

We install an external siphon for a washing machine

The advantage of outdoor equipment is its ease of installation. The procedure will be as follows:

1. Choosing a place for installation. Keep in mind that the installation height of the siphon for the washing machine is not too large. The optimum distance from the floor is 500 mm. Do not mount the device directly above household appliances.
2. Equipment is connected to the sewage system using sealant or rubber gaskets.
3. A crimp sleeve is used to connect the drain hose to the inlet.

Built-in equipment: installation procedure

The main disadvantage of this method is the need to equip a special niche in the wall. The installation algorithm is as follows:

1. Choosing a place to install equipment.
2. Using a drill or punch, make a niche whose dimensions exceed the dimensions of the siphon by 30-50 mm.
3. Installation of equipment in a niche with the subsequent connection of a siphon, in accordance with the instructions. Before starting operation, be sure to check the tightness of the connections.
4. Putty of the remaining space in a niche, installation of decor.

Important! The built-in siphon for the washing machine is the best option for arranging the hidden wiring of water and sewer pipes.

Connection Features

In the vast majority of cases, attaching the “washer” to the siphon does not cause any difficulties. Most often, the connection is made by pulling the drain hose on the socket. Sometimes a flare nut is used. However, for the correct connection of equipment, a number of rules must be observed, neglect of which threatens premature breakdown of household appliances:

• The correct choice of height for connecting the drain. If it exceeds 0.8 m from the floor, the pump will experience overloads, which can lead to breakage.
• The length of the drain hose. Hose extension is undesirable, as this entails additional load on the pump. A more preferable option is laying a thin (32 mm in diameter) sewer pipe to the machine. If the hose, on the contrary, is too long, it should be mounted on the wall, while ensuring the slope necessary for unimpeded drainage.

Important! There are many more nuances regarding the installation of the washing machine itself, its connection to the water supply, electricity.You will find detailed instructions on them in a separate article of our portal of useful tips.“Connecting the washing machine”.

How to connect the inlet and outlet system for the washing machine:

• The pipe, which is used to supply water to the washing device, is led to any place that is convenient for tapping. In the selected place, a compression shut-off valve is installed, to which a water hose from the washing machine is connected.
• A hose designed for drainage is connected to the sewer pipe. The outlet from the washing machine is formed by a pipe of 40 mm diameter and a siphon, which are interconnected.
• It is useful to purchase the installation kit for the washing machine, equipped with fasteners, in addition to the pipe and siphon for the washing machine.
• It is necessary to carefully study the requirements for the arrangement of the outlet pipe. If such requirements are not specified, it is recommended to follow the general rules. The height of the open upper end of the pipe is 0.5-0.6 m from the floor. The slope of the pipe to the sewer riser should be 2 cm per meter of pipe.

Important! When connecting the discharge hose from the washing device to the pipe under the sink, it is necessary to provide for the installation of a check valve.

Can I save on installation?

It turns out that this option is quite possible. You can create a water lock using a flexible hose, which is designed to connect the washing machine to the sewer. The hose is placed so that it forms a bend in the lower part. It is in this bend that the water necessary to create a water seal will accumulate.

This design is economical, but has several disadvantages:

• The load on the pump increases due to the increase in output length.
• Difficulties with cleaning the design - the need to dismantle the outlet hose, and this is inconvenient.

Important! Another important nuance is the power supply of household appliances. If you decide to put a wash in the bathroom, be sure to read about what should be outlet in the bathroom.
