Step-by-step instructions: how to connect a washing machine to the sewer with your own hands

Proper installation of a new washing machine will avoid problems with water leakage and incorrect operation of the device in the future.

Connecting a washing machine is not as difficult as it might seem.However, there are a few important rules to keep in mind.

In this guide, we will show you step by step how to connect the washing machine and lead it to the drain with your own hands.

What tools are needed to install a washing machine

When installing a washing machine, you may need:

• building level;
• threaded adapter;
• ball valve;
• fitting, tee or compression coupling;
• a set of adjustable and wrenches;
• Phillips or flat head screwdriver (not always required)
• flexible hose.

Where to install a washing machine

The most popular and optimal place to install a washing machine is under the sink in the bathroom. In second place is embedding in the kitchen set.

But in fact, the issue of installing household appliances is the business of each individual user.

The main thing is that the device has free access to communications: drain pipes, water supply and networks.

A much more important point when installing a washing machine is its proper alignment.

If it is installed incorrectly, in the future it will move during washing and be very noisy. Therefore, it is necessary to adjust the height of the legs.

To do this, use the building level and a flat wrench to unscrew the special fixing nuts at the base of the equipment.

Adjusting the height of the legs will help to avoid loud operation of the device, especially during the spin cycle. And do not forget to tighten the locknuts on the device body afterwards.

The connected and leveled washing machine can be placed on an anti-vibration mat, which further reduces the noise level during operation.

Electrical wiring requirements for a washing machine

As for connecting to the mains, everything is quite simple. The only thing you need to pay attention to is the appropriate parameters and grounding of the outlet - according to the standard, a voltage of 220-240 Volts at 50 Hz is sufficient.

It is also not recommended to use extension cords or splitters. Of course, the cable should not come into contact with sources of open flame.

Connection to various types of pipes

Depending on the type of pipes used, connecting the washing machine to the water supply will require different measures on your part.

Unfortunately, in most cases, the use of a welding machine is indispensable, since it is necessary to ensure a tight connection of pipes and fittings.

Connection to a metal pipe

If your pipes have a special faucet for connecting household appliances, simply screw the hose into the faucet, using a nut and silicone grease to seal.

Otherwise, you will have to tie in: for this, you need to put a compression sleeve on the pipe and fix it with bolts. After that, a hole is drilled in the pipe and it is connected to the coupling through a special threaded fitting.

When all actions are completed, a tap and a drain hose are connected to the corresponding hole.

Connection to a metal-plastic pipe

When working with a metal-plastic pipeline, you will first have to cut the pipe with a special pipe cutter and install a metal tee with a shut-off valve in it.

A flexible hose is already connected to it, i.e. this device also serves as a pipeline conductor to a household appliance.

Connection to a polypropylene pipe

The easiest way is to connect the washing machine to a polypropylene pipeline.

In short, just like with metal-plastic pipes, it is necessary to install a tee on the pipe, to which the hose of the household appliance is connected through the stopcock.

However, polypropylene pipes are connected not butt-to-butt, but by separate sockets, which means that you do not need to weld pipe sections, it is enough to use specialized glue.

Instructions for connecting to the water supply system

Before proceeding with the installation of the washing machine, open the faucet and drain the water with any possible contaminants that may have accumulated in the pipes.

Before turning on the washing machine, make sure that the water is completely clean.

So, screw the inlet hose into a tee with a shut-off valve embedded in the pipe. It has a flat surface and a threaded tip, which is best wrapped with fum tape.

Tighten the hose by hand, as the outlet thread is very soft and the use of a tool can damage it.

If your model of washing machine does not have a permanently installed inlet hose, you can also screw it into the washing machine yourself. If all is well, he can open the water tap and check the tightness of the connections.

There is an important point: the inlet hose often has a valve that shuts off the cold water supply (called a solenoid valve), which can prevent water from leaking into the house.

This technology is popularly called Aquastop. In models with such a system, the plumbing is already integrated with a solenoid valve.

After connecting, you should carefully open the valve and check the tightness of the installation, but you should not extend such a hose on your own.

Hoses with solenoid valves have a certain factory length. In this case, the manufacturer cannot guarantee the strength or tightness of the installation.

Organization of a drain in a sink or toilet

The correct height of the drain should vary from 40 to 100 cm from the floor, although these values ​​(especially the lower ones) may differ depending on the model, so it is best to respect the upper limit.

Sometimes the factory hose connection may not be enough and may need to be extended. To do this, you need to connect two hoses, for which special double-sided fittings are used.

Most often, this is a fitting with holes with a diameter of 3/4, which are covered on both sides with sealing cuffs that prevent the water drained from the washing machine from flowing out.

Thanks to this set, the water from the washing machine can be drained even from household appliances that are far from the sewer.

As already mentioned, for many washing machines, for example, for most appliances from Bosch or Indesit, you can buy a hose extension or simply purchase a longer version that will direct water directly into the sewer.

A good two-meter hose is more than enough to connect the washing machine to the right place in your home. If necessary, you can adjust the length of the hose to suit your needs.

Just connect the drain pipe to the siphon. Position the inlet in a vertical position.

Thanks to this, in the event of an unforeseen situation, you minimize the risk of flooding the premises.

It is also worth installing special gaskets, which further eliminate the risk of unpleasant odors. If you are connecting the drain hose to a siphon, you may need a hose clamp of the correct size.

How to crash into a sewer pipe

When integrating various household appliances into centralized water supply systems common in the CIS countries, it is required to perform certain actions to insert the device into a common pipe.

Moreover, the pipe itself can be old and rusty, not having any special taps for connecting household appliances, which further complicates the process of connecting with it.

So please note that it is recommended to entrust the described actions to specialists, since a non-professional risks simply damaging communications.

The method of tapping into a sewer pipe using a tee

At the beginning of the article, we described how to connect household appliances to various types of pipes.

Now we get into the process itself in more detail:

1. So, tie-in into cast-iron pipes, the most common in residential buildings of the post-Soviet states, requires special adapters - tees, which ensure a tight connection of the pipe with the inlet hose of the washing machine. You can buy such a tee at any hardware store.
2. Then, before starting work, it is necessary to completely block the sewer system. In apartment buildings, this means that neighbors should not use the sewer for some time, that is, not use sinks, washbasins and toilets. If it is not possible to agree with neighbors, it is necessary to prepare containers for draining waste.
3. First you need to make all measurements of communications at the installation site. Since you will need to cut an entire segment of the pipe, make sure the measurements are correct.
4. The first thing to do is to cut out the part of the pipe where the tee will be integrated into. To do this, you can use a special pipe cutter, but you can get by with a grinder. At the same time, the grinder may not reach some places, so you can complete the procedure with an ordinary hacksaw. Of course, you need to be careful, because cast iron pipes are very fragile.
5. Now you need to mount the tee. Start by placing it on the short section of the rack and set it aside. Then move the movable part of the pipe in the same direction and put it on the tee. After that, it is necessary to align the riser line and insert the pipes into the tee as deep as possible. If necessary, you can temporarily fix the pipes with a bracket to make it more convenient.
6. Finally, you need to connect the old pipe to the tee.This is a very complicated procedure, especially in old Soviet houses, where the pipes run extremely low and, in principle, are difficult to access for welding. In this case, for the joint of the seams, you should use a high-quality silicone sealant or epoxy resin. In order to avoid leaks, it is also recommended to pay attention to the sealing tape, which works great with cast iron pipes. It is enough just to wrap the edge of the pipe with tape in a couple of layers.

It must be emphasized that all of the above procedures are carried out by welding, so too dot marking is not necessary.

The method of tapping into the riser without cutting the pipe

The second common method of inserting a pipe requires a special collapsible clamp, consisting of a bandage - crimping material made of steel, and from a cuff - an internal sealing seal.

A branch pipe is attached to one half of the clamp, which connects directly to the sewer pipe, and, accordingly, to a certain plumbing product.

So, consider the order in which the clamp is mounted:

1. First you need to completely block the sewer in the house. As mentioned earlier, for this it is necessary to ask the neighbors above and below not to use plumbing for a while. You also need to turn off the water, but this is a little easier - the landlord can independently block the water risers. To do this, each apartment has two corresponding valves - hot and cold water.
2. Next, you need to use a drill to make at least two holes in the pipe and in the "ears" of the clamp.Their size depends on the diameter of the bolts used to fix the clamp. If the bandage is more than 6 centimeters wide, not two, but three holes should be made.
3. The next step is to fix the clamp with a pipe on a polypropylene pipe. The clamp is mounted by diluting the “ears” so that they can wrap around the entire pipe and then tightening the bolts.
4. After that, a rubber seal is inserted into the pipe, repeating the shape of the corrugation.
5. Finally, the outlet pipe is inserted into the corrugation itself.

You can also make such a collar yourself.

Here is a step by step guide to making a pipe clamp at home:

1. Choose the right polypropylene pipe. The main condition is that the internal section must be the same as the section of your pipeline.
2. Then, from this pipe, you need to cut a segment that is larger than the length of the outer section of the pipe by about 5-10 centimeters.
3. This pipe must be cut into two parts with a hacksaw (along). You use one half as the outer back of the clamp.
4. In the second half, it is necessary to make a hole, the cross section of which must correspond to the outer diameter of the installed pipe.
5. Finally, stick the outlet pipe into this hole and carefully process the clamp with sealant inside.
6. The last stage is the direct fixing of both structural elements of the clamp on the pipe.

We would like to note that in order to ensure complete sealing of the joints, metal tape clamps should be used when attaching the edges of both halves.

The method of inserting a drain pipe into the sewer

Many owners, when trying to connect household appliances to the sewer system, have a very unpleasant problem - the pipes into which it is necessary to make a tie-in turn out to be literally immured into the wall.

Moreover, this is a common situation not only among Soviet houses, but also among many new buildings. Therefore, specialists do not waste time creating an additional entry into the siphon, but simply cut the outlet directly into the sewer pipe.

To carry out this operation, you will need the following components:

• electric drill with a sufficiently large drill;
• clamp for securing the outlet from the washing machine;
• plumbing fum tape (fluoroplastic sealing material);
• metal strips.

However, keep in mind that since you are working directly with a sewer pipe, the procedure will not be pleasant. Although, if you drain the water, the unpleasant smell will decrease.

So, let's consider the whole installation process step by step:

1. Metal strips must be fixed on the outlet. For this, as in the previous described method, a clamp is mounted.
2. A connector is drilled in the pipe in the form of a circle, which should be slightly smaller than the cross section of the outlet. To do this, you need a large drill to widen the hole if necessary.
3. The outlet pipe is wrapped in a fum tape, after which it is quietly inserted into the connector made. Keep in mind that it should fit as tightly as possible, so don't be afraid to use as much tape as you need. Your goal is a tight connection.
4. Finally, it remains to fix the pipe on the wall. To do this, you need to securely attach the metal strips to the wall with dowels, and then place the pipe there.

Also remember to wrap the ends of the pipe with sealant before tapping to give them maximum strength.
