Connecting the washing machine to the sewer and water supply - 2 main methods

Specialization: master of interior and exterior decoration (plaster, putty, tile, drywall, wall paneling, laminate, and so on). In addition, plumbing, heating, electrical, conventional cladding and balcony extensions. That is, repairs in an apartment or house were done on a turnkey basis with all the necessary types of work.

If you need to know how to connect a washing machine to the sewer, then you have come to the right place to come for advice. I want to talk about two main methods that are generally possible to apply in this case. In addition, I will explain the features of the tie-in, and also suggest that you watch the video in this article.

Two methods

There is another, third way, which you see in the photo above.
But this is no longer a connection, but simply fixing the hose with a U-shaped adapter over the side of the bathroom.
Such a U-shaped fitting is included with every automatic washing machine.

Method one

It is not for nothing that I focus your attention on the machine, since the water is drained there forcibly. Therefore, the entire instruction that will be below refers specifically to this type of washing machine:

• on the plumbing market, siphons for sinks, sinks and bathtubs are currently on sale with an additional outlet for connecting a hose 22 mm in diameter;
• we can say that it is precisely such siphons (with an additional outlet) that are offered much more than ordinary ones;
• if you install such a siphon, but for some reason you will not connect the washing machine, then the output can be closed with the plug that comes with the kit.

Method two

But the correct connection of the washing machine to the sewer directly into the pipeline may differ slightly:

• the hose, which is designed to drain water in the washing machine, has a diameter of 22 mm, but there is no special socket for bends to 50 mm or 32 mm pipelines;
• therefore, a rubber reduction with a transition of 22 mm is used here for connection- its price is rather symbolic, but the device is fully consistent with the purpose - it is convenient and airtight;
• if your washing unit is in close proximity to a 50 mm sewer pipe, then of course you will crash into it through a tee;
• but if the machine is located at the other end of the room, then a 32 mm PVC pipe should be used, connecting it to a 50 mm outlet;
• in such cases, the scheme for connecting the washing machine to the sewer does not require the installation of the 32nd pipe under a slope, since the drain is forced here;
• The 32nd pipe into the outlet socket of the 50th is also connected using a rubber reduction.

The drain hose for some units has a diameter of 19 mm on the machine side and 22 mm on the pipeline side.

Features of connecting a washing machine

First of all, you should know if your washing machine has a check valve on the drain that only allows water to flow in one direction. Only in this case you will be able to figure out how to properly connect the washing machine to the sewer.

If such a device does not exist, then the manufacturer must indicate the height level at which the hose loop should be - a water loop is created in this area. This closure mainly serves to prevent the leakage of unpleasant odors that may pass from the sewer through the machine.

In the latest models of automatic washing machines, for the most part, a check valve is provided, so in this regard there should be no questions about how to connect the hose. Your task is only the correct connection of the end pipe (it is smooth, without corrugation) with a rubber reduction or with an additional siphon outlet.

In order not to damage the rubber reduction, I usually lubricate it with liquid dishwashing detergent - this way it is easier to pack it into a socket and stick a smooth pipe into it.

If the connection is made through an additional outlet of the siphon, then there you just need to remove the tube that is inserted there from the factory and install a hose pipe instead. To seal the connection, there is a coupling - in the image it is indicated by the number 8 - it presses the cone gasket, which, in fact, provides a seal in this place.

That is, the tube that is in this siphon from the factory is installed there more to keep these parts in working condition.

If the standard drain hose does not reach the tie-in into the sewer, then it can be increased by adding a piece of the desired length and connecting these fragments with a fitting with insurance with steel clamps 16 × 27 mm. As I said, the end pipes can have different diameters, which is why there are connecting fittings for two options - you can see them in the top photo.

There are also modular hoses on sale, where each of the fragments has a length of 0.5 m, so that you can fulfill any requests. But at the same time, do not forget that the longer the outlet, the more difficult it is to cope with the water supply.

Water connection

In this case, oddly enough, connecting the unit to the water supply is much easier than to the sewer, since here, in fact, there is no choice. In any case, the pipeline with the water supply must be located near the automatic machine and it must have shut-off valves in the form of a straight or angle valve. There are two clamping nuts on the hose itself, therefore, on the machine itself and on the shut-off valves there must be a fitting with an external thread.

It is noteworthy that the nuts are designed for a 3/4 inch diameter, therefore, the valves must have exactly the same thread. But if a special tap that is designed for this purpose is done at 3/4, then the plumbing most often has 1/2 inch. Therefore, in some cases, a reducing fitting will be required for connection.

Conclusion

In fact, connecting the unit with your own hands to the sewer is quite simple, if at the same time all the connections are made carefully, that is, tightly. But if you still have a misunderstanding in this matter - ask about it in the comments.
