How to connect the drain hose of the washing machine to the sewer

How to connect the drain hose of the washing machine to the sewer? It seems to be simple, take it and plug it in, but it wasn’t there. Improper installation of the drain hose of the washing machine can lead to a number of problems in the near future. Even with such a simple action, you can not neglect the simple rules for connecting the washing machine, which we will talk about today, despite the fact that there are not so few ways to do this.

How to connect?

You can connect to the sewer, as well as organize the discharge of waste water from the washing machine, in different ways. Connection is organized depending on a number of factors:

• how close the sewer drain is to the washing machine body;
• Is there any connection point within reach?
• at what height and at what angle relative to the washing machine body this point is located;
• what other equipment will have to be connected to the sewer along with a washing machine, etc.

The angle of placement of the drain hose relative to the location of the washing machine is very important to consider. If the hose is not positioned correctly, a "siphon effect" occurs, water from the sewer pipe will go back to the bowels of the washer.

Based on the above factors, there are three main ways to organize the discharge of waste water for a home assistant. Firstly, the drain can not be organized at all if you drop the drain hose into the adjacent plumbing, for example, into the bathroom, sink or even the toilet.

Secondly, the washer can be connected to the side outlet of the siphon. This branch is ideal for screwing a drain hose to it and forget about the problem once and for all. And thirdly, the drain hose of the washing machine can be secured with a hose clip after having previously thrust such a hose into a branch of the sewer pipe - cheap and cheerful, and most importantly you do not need to buy a special siphon with a drain for the sink. We will talk more about how to implement these three methods of draining water a little later, but for now we will focus on the nuances of importance that can affect the quality of such a drain.

What else matters?

Why are we talking about the quality of the drain, and what is the difference in general, what kind of connection to the sewer we have chosen, the main thing is to do everything relatively correctly, and then it does not matter. So many people think that they independently undertake to connect an automatic washer to the water supply and sewage systems and thereby, unwittingly, shorten the life of their “home assistant”. What, specifically, is it about?

Let us explain with a specific example. We connect two absolutely identical washing machines to the sewer. The first machine is not far, at a distance of 1 m from the connection point, we connect it with the supplied 1.5 m drain hose, in compliance with all the rules. The second machine is located at a distance of 2.4 meters from the connection point to the sewer pipe or siphon, we connect it with the help of an optionally purchased drain hose of 3 m length.

Both washers have been in operation for 7 years. The first washing machine worked this time without breakdowns, the second one changed the drain pump 2 times: the first pump broke after 4.5 years of operation, the second in the seventh year of operation. “Debriefing” revealed many of the alleged, but still not uninteresting regularity. The longer the drain hose of the “home assistant”, the more often the pump will break, because when it works, it will experience loads that exceed the calculated ones.

Place the washer as close to the point of its connection to the sewer as possible.

It is also of great importance how the washing machine is installed on a horizontal surface, since this also affects the working life of the pump, engine, as well as the working connections of hoses and pipes, as well as electrical wiring. It is very important that the washer is not only installed in level, but also stands on a flat, solid surface, which over time does not bend and does not become loose from constant vibration.

Various modern additions are also important, which allow, on the one hand, to facilitate the process of connecting the washer to the sewage system, and, on the other hand, to further protect it from some risks, especially the “siphon effect”. Mentioning this, we mean drain hoses with a non-return valve. Such a valve is specially designed so that sewage from sewers does not, under any circumstances, fall back into the washer, while draining will be completely free. You can read about this device in the article. Check valve for washing machine.

Consumables and tools

Before installing the washing machine, including connecting it to the sewage system, you must acquire all the tools and materials that will be required for this work, so that you do not have to take breaks later, to run to the store for a clamp or jumper. So, let's start with the tools.

• Large and small adjustable spanner.
• Screwdrivers (flat and Phillips).
• Fixture for cutting plastic pipes.
• Pliers.
• Sharp knife.
• Roulette.
• Building level.

The tool kit is not rich. It is immediately clear that the entire list can be easily found in any pantry. If you did not find a device for cutting plastic pipes, you can use the usual hacksaw instead of it. Now we will deal with the materials.

1. Drain hose of the desired diameter and length.
2. Plastic sewer pipe and tee for it.
3. Jumpers and clamps.
4. Non-return valve.
5. Automotive or plumbing sealant.
6. Winding up.
7. O-rings and gaskets.

Before you buy small consumables, such as o-rings and gaskets, count how many are needed.

Without connection

Now let's talk directly about how to properly connect our washing machine to the sewer. And, we will begin with the simplest version of the organization of the discharge, which, paradoxically, does not involve connecting the washer with a sewer pipe. Let's talk about him.

This method is good for lazy people, because its implementation does not need a lot of materials and tools. Yes, and time will be spent at least. However, some conditions must be met.

• Close to the washing machine casing, a sink, bathtub, shower cubicle with high enough sides, toilet bowl or trouble should be located at a suitable height.
• It must be possible to secure the drain hose. Why fix it? And then, so that he does not accidentally jump out of the plumbing element when water rushes under pressure from the tank of the washing machine through a hose to the drain of the sink, bathtub, etc.
• People who use plumbing should not be squeamish, since they will have to endure some inconvenience that will arise in connection with a similar organization of draining water from the washing tank.

To organize the drain in this way, it is necessary to lower the hose of the machine into the bathtub, sink, toilet bowl, etc. not tight. Ensure an S-shaped bend of the hose. Fix it to the wall of the sanitary element so that it does not hang loose, and then carry out the tests. If the drain is carried out normally, you can leave everything as it is, the work is finished.

Through the siphon

The installation of the connection in this way is special in that we do not connect the drain hose of the washer to a sewer pipe or its branch, but to another plumbing element - a sink siphon.In modern siphons, manufacturers provide a special outlet for connecting a washing machine, which we should use.

There are siphons with two taps to simultaneously connect a washing machine and dishwasher.

The essence of connecting the washer via a siphon is as follows. We install a siphon and check how the water is drained through the drain hole of the sink, see that there are no leaks. The siphon can be easily installed with your own hands without any tools. If you have problems with this, you can read the article Siphon for a washing machine - installation and connection. Next, we connect the drain hose to the side outlet of the siphon, not forgetting to seal the joint. The hose must be bent with the letter “S”, if this is not done, the first wash will result in the machine freezing in the middle.

Directly to the sewer pipe

You can also connect the washing machine to a sewer pipe outlet located nearby. To do this, a similar challenge must be organized. We do the following.

1. We get a tee for a sewer pipe.
2. Using a pipe cutting tool, we cut the plastic sewer pipe.
3. We install a tee, seal the junction.

Well, the pipe outlet is organized. In this case, it is very important that the tap is located at least 40 cm above the floor. We insert the end of the drain hose into the pipe outlet and seal the connection. We strengthen the connections with an additional clamp so that the pipe does not accidentally jump out and flood the entire floor due to pressure. We bend the hose with the letter “S” and fix it so that it does not hang.

In conclusion, we note that connecting the washing machine to the sewage system is really not difficult, if you follow the simplest instructions that have long been formulated by experts. You can do it too. Read this article and get to work, good luck!
