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 order.
If the standard drain hose does not reach the tie-in to 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 is 0.5 m long, 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.
For the correct and trouble-free operation of the washing machine, it is necessary to properly connect the washing machine to the sewer. You should know, first of all, that when choosing a place to install a washing machine, you must take into account the length of the drain hose. It is also necessary to take into account the diameter of the sewer pipe when leading it to the washing machine. The diameter of this pipe is 40 mm miniaml.

You should know, first of all, that when choosing a place for it is necessary to take into account the length of the drain hose and the connection diagram. It is also necessary to take into account the diameter of the sewer pipe when conducting it to. The diameter of this pipe is 40 mm miniaml.
Draining the washing machine: connection to the sewer
After completing the stage of work on bringing water to the machine, we will consider several basic options for connecting the drain of the washing machine. In any case, this issue should be taken seriously, because when the water is drained by the machine, the hose can pulsate strongly and the unreliability of the connection can cause water leaks, which can significantly spoil the mood and property not only for you, but also for the neighbors below.
Option 1. With the help of the clamp that usually comes with the washing machine, you can secure the drain hose to the side of the tub or sink. In this case, the possible height of the hose must be taken into account. It is indicated in the installation and operating instructions, usually manufacturers recommend that it does not exceed 100 cm. Otherwise, the pump power may not be enough to drain all the water. In addition, it makes sense to provide a rigid fastening of the latch, for example, to a water tap.
Option 2. The second way to connect the washing machine to the sewer is to connect the drain hose directly to the siphon. In this case, you get rid of the need for additional cleaning of the sink or bathroom at the drain. 
What is a siphon? This is a curved tube through which water from the sink enters the sewer. The bend is necessary to create a water blockage, which prevents the penetration of an unpleasant odor from the sewer pipes.
There are several types of siphon designs. The simplest is a conventional flexible corrugated pipe. A special clamp is used to fix the knee. The advantages of such a siphon include low cost and ease of installation, so it can often be found in new homes.
The second, most common type of siphon is a bottle siphon. It is equipped with a special flask in which a water jam is created. In addition, if you accidentally drop the ring into the sink, it will linger at the bottom of the flask.
When organizing the drain of the washing machine, you can use special siphons, which are equipped with additional outlets for drain hoses. They can be purchased at a hardware store. If the siphon is correctly installed, you will get a neat connection for draining the washing machine directly into the sewer. It is worth noting that this work often requires appropriate skills and its solution should be entrusted to a qualified plumber.
Option 3. You can lay an additional elbow from the existing sewer pipe, where the sink is drained. In this case, an additional set of sewer pipes with a coupling and a reducer is required, which acts as an adapter from the drain hose to the standard sewer pipe. All connections must be strong, for this it is advisable to coat them with plumbing silicone.
Connecting and installing a washing machine
Installation and connection of the SMA consists of several operations:
Remove shipping bolts, place the machine on a firm, level surface, level the machine.
Connecting the washing machine to the mains. If you recently had a renovation, or you live in a new building, most likely you already have a special outlet for SMA, then there is no problem. If not, then you will have to pull a separate line from your electrical panel without fail. This is the most time-consuming and expensive operation in the entire installation procedure. You will need a circuit breaker 16A, a wire with a cross section of at least 1.5 square meters. mm., a waterproof euro socket with a grounding terminal, and, accordingly, lay and install all this. 
Connecting the washing machine to water. Here you need a special tap - with a ½ x ¾ thread, or an angled or through passage, depending on the specific conditions. If the apartment has a separate water outlet for connecting the washing machine, a corner tap is installed, if not, a passage tap is installed in the break of the water outlet for cold water and flexible supply to the mixer, or the toilet barrel. If the apartment does not have coarse water filters, it is advisable to install the filter in front of the water supply tap to the washing machine. Next, a supply hose is connected to the tap. If the supply hose is equipped with an aquastop device, it is recommended that it be positioned vertically. If the length of the supply hose is not sufficient, it can be extended using special materials.
The next step is to connect the washing machine to the sewerage system. There are two main ways. Connecting the nearest plumbing fixture to the siphon (kitchen sink, washbasin, etc.) in this case, the siphon changes to a special one with a tap for the washing machine. This method has a significant drawback - if the siphon is clogged, dirty water from the washing machine will flow into the sink. However, this is a very common way. Another way to connect the washing machine to the sewer is to install a tee directly into the sewer system. This method is more preferable, does not have the disadvantage described above, but is slightly more expensive for the consumer.
And the last stage is a test run. The performance of the machine is checked, without linen, with a small amount of powder, at the same time it will be washed. It is enough to fill in water, stop the program, turn on the drain, check all connections for leaks.

Correct installation of the drain hose of the washing machine is the key to its successful operation. It is necessary to do this so that the waste water flows freely into the sewer pipe. It is not difficult to perform this work, it is quite possible to do without inviting a specialist. How exactly to select components and assemble them into one system - we will tell in this article.
Connection methods
There are several methods for connecting the washer drain to the sewer. Each has its own advantages and disadvantages. Here are the ways:
- Insertion into the sewer.
- Descent of water through a nozzle with a tap, which is located above the siphon.
- The direction of the waste of washing through a siphon with a branch.
- Descent of waste water over the edge of the toilet bowl, tub or sink.
Important! The location of the washing unit plays a decisive role in choosing the method of arranging the drain. Most often it is in the bathroom or in the kitchen. In the kitchen, the drain is directed through a siphon or tie-in, no matter how far the communications are located. To equip the drain over the edge of the sink is unacceptable for sanitary reasons.
In the bathroom, there are much more options:
- Next to the bath - over the edge of the bath.
- Next to a toilet or sink. Options are available through a siphon or tie-in. The most inexpensive way is over the edge of the toilet bowl or sink.
- Instead of a washbasin - through a tie-in or siphon.
In all the above cases, there is a possibility for an optimal connection of the drain.
Tool, consumables
The choice of tool largely depends on the material of manufacture of sewer pipes. The classic set of tools is as follows:
- Wrenches, wrench.
- Screwdriver, drill.
- Pipe cutter - when working with a metal-plastic pipe.
The list of consumables depends on which drain method you have chosen. It usually includes:
- Hose. Its length depends on how far the communications are from the washer.
- Ball valve.
- Seals.
- To connect over the edge of the bath - self-tapping screws.
- Tee.
- The siphon equipped with a branch pipe.
- Liquid rubber, silicone-based sealant.
In the sink, toilet or bath
When organizing a drain in this way, a curved drain hose is hung on the edge of a sink, toilet or bathtub, and after washing is returned to its original place. The disadvantage of this method is that the drain can accidentally break, then the flood cannot be avoided.
Important! This method of organizing the drain is considered the most economical and simple. The set of tools and consumables here is the most minimal, since the washing unit is equipped with almost everything you need for work.
The procedure for organizing the drain is extremely simple:
- Drill a hole above the bath for the plug so that the end of the mounted hose is in the bath.
- Screw a self-tapping screw into the resulting hole.
- Disconnect the corrugated hose with a plastic bracket and a mounting hole from the rear wall of the washer.
- Hang the hose on the screw.
Important! This fastening allows the hose to hold well, without coming off or shifting from the vibration of the washer or from careless movements.
The method also has quite significant disadvantages:
- Do not bathe in the bath while washing.
- Waste water after washing contributes to the pollution of the bathtub or sink, and also destroys the coating.
- Cleaning the tub after washing is required.
Through the tee
In this case, a special nozzle equipped with a tap is mounted under the sink. The procedure for this is as follows:
- Disconnect the drain pipe that comes from the sink.
- Install the tee as high as possible (well, if under the very opening of the sink). This is to prevent backflow of water.
- Return the equipment to its place.
- Connect the nozzle to the extension hose.
Important! In order to prevent an unpleasant smell from appearing in the tank of the washing unit, twist the hose near the connection point in the form of the letter S, while not obstructing the free movement of water. To prevent damage to the connections, position and secure the tubes so that they do not interfere with free movement.
Siphon with non-return valve
If you properly mount such a system and find out how it is produced, you can forget about such a problem as the appearance of an extraneous odor. And the built-in non-return valve creates an obstacle for the reverse penetration of waste water.
Connection nuances are as follows:
- The tee is replaced with a new siphon. A hose is put on the outlet of the tee.
- The connection to the pipe is fixed with a sealing sleeve - it can be included. If not, it is purchased separately.
- The insertion site is treated with a sealing compound. This is an additional protection against sewer odors.
A rare person now does without a washing machine. Qualitatively executed and carefully selected equipment will last a very long time without failures and utility accidents.
One of the components of such reliability is the correct connection of the washing machine drain to the sewer. Unlike providing equipment with electricity and tap water, the drain device requires more attention.
Can I connect the washing machine to the sewer myself? Such work is quite accessible to any home master who has already dealt with plumbing. If there is no experience, then you need to show increased attention.
Before starting work and before purchasing all materials, it is necessary to study ways to drain dirty water and choose the most suitable one. What influences the choice:
- distance from the washing machine to a convenient drain point;
- material of existing pipes in the apartment / house;
- length, diameter of hoses included in the kit and purchased as needed.
It is best to first sketch out the simplest scheme for connecting the machine to all networks - it will be easier to imagine the big picture, make calculations of the amount of work and the amount of materials.
Drain device methods
There are only three of them, from the simplest and cheapest to the more complex and costly.
Descent of water into plumbing
Included with any washing machine is a “hook” - a plastic element in the shape of an inverted “U”. A drain hose is fixed in it, after which the “letter” can be planted on the edge of the sanitary tank. Usually the place of the drain becomes a bath, as an option - a sink or toilet.
In fact, this method of draining is almost always inconvenient. If you still decide to use it, then you need to consider:
- the drain hose holder must be well fixed on the edge of the sanitary tank;
- during washing, you will not have to use the plumbing into which the drain jet is directed;
- it is advisable to wash off the sediment contained in the waste water of the washing machine after each wash: the smallest particles of pile and various grains of sand are often not visible, it is easy to forget about them until the accumulations become really noticeable and difficult to clean off.
If this method of getting rid of waste water is not suitable, the owners have no choice but to connect the drain of the washing machine to the sewer.
Inserting the drain hose into the siphon
A very popular way if the washing machine is close to the sink. There are several options for draining a washing machine into the sewer through a sink siphon.
One of the simplest is to assemble a system under the sink from a conventional siphon and a tube with a tap. Such a scheme is simple and reliable: the drain hose of the washing machine goes to the siphon, rises just above the inlet and enters there from top to bottom.
Due to this height difference, water from the sink drain will not be able to penetrate the drain hose when it is empty. One problem still remains. The smell of sewage can penetrate into the cavities of the washing machine and even soak into the laundry.
But this can be solved if we complicate the circuit a little. You can assemble a system with a water seal under the sink. At a glance, it looks like a lying letter "S". A small amount of water always accumulates in one bend, which does not let sewer odors out or into the washing machine drain hose.
Another option with the same effect is to buy a special anti-siphon valve for a washing machine with an outlet for attaching a drain hose.
Drain into the sewer
What to do if the previous methods of getting rid of dirty water are not suitable? The last option remains: arrange the drain of the washing machine into the sewer directly. This method is usually the most time consuming and expensive. But it is ideal if the washing machine is installed far enough from the sink.
The material of the existing sewer is important here. Tapping into old cast iron pipes can be quite troublesome. It is rarely possible to limit ourselves to just connecting a washing machine. Sometimes it is necessary to replace a section of the pipeline from cast-iron pipes. You have to act according to the situation.
In other cases, the work is usually easier. The owners of new cottages turn out to be in the most advantageous situations: in this case, a sewer outlet for a drain device can be provided in advance.
Connecting the drain of the washing machine to the sewer under the bathroom is one of the popular ideas. The advantage of such a drain system is that the hose can be hidden with a special screen, the design of the bathroom will only benefit from this. It is only important not to make the mistake that inexperienced craftsmen often make.
We are talking about the horizontal entry of the drain hose into the sewer. This is absolutely the wrong decision. The drain hose for the washing machine will inevitably be filled with the contents of the bath and sink drain, if any. We've already talked about bad smells. To avoid such an error, the drain hose must be inserted into the sewer from top to bottom.
Materials, tools, tricks
What the home master will need:
- Drain hose. Under good circumstances, you can use the one that comes with the washing machine. In other cases, purchased separately. We must not forget that the length of the hose is calculated with all the ascents, descents and bends.
- Means for sealing holes, joints, joints, gaskets for sealing, silicone sealant. In any plumbing work, special attention must be paid to preventing leaks.
- Sewerage fittings (tees, adapters), pipes, siphon, check valve for the washing machine to drain - depending on the connection method chosen. Diameter, length and type are calculated according to the situation.
- Pipe cutter, if you plan to tie into the sewer directly.
- Allen wrench or wrench set.
Regardless of the chosen method of connecting the drain hose to the sewer, it is necessary to carry out tests immediately after the completion of all work and arrange an idle wash. Then possible defects will immediately become visible. If everything is done correctly, then the drain system will last as long as the washing machine itself.
If you understand all the details with how to properly connect the washing machine, this operation will not be difficult to do with your own hands. In the article we will describe the process of connecting the drain hose of the washing machine to the sewer.
The issue of connecting the washing machine to the sewerage and water supply should be approached as responsibly as possible. Only in this case the unit will work without errors and problems. objectively simple. All home masters cope with a similar task without any difficulty. But many craftsmen organize the drain of the unit into the sewer system incorrectly. The result is unpleasant odors in the room where the machine is installed, as well as clogging it with water from other plumbing fixtures.
Drain connection
The drain hose from the washer to the sewer is connected in three ways:
- By installing a special siphon.
- Installing the hose directly into the pipe of the sewer system.
- By throwing a hose over the edge of a washbasin or bathtub.
The third technique is very simple. To implement it, you do not need to mess with pipes, purchase and install a siphon. All work takes a matter of minutes - throw the hose into the sink (bathtub), fix it with a plastic hook (it comes with all washing units) and watch how dirty water goes into the sewer system after washing. It would seem - much easier? But this simplicity is fraught with many problems. Firstly, the water from the machine will constantly pollute the washbasin or bath. After two or three washes, you will be horrified by the appearance of sanitary fixtures. Unattractive streaks will appear on their acrylic or enameled snow-white surface.
Just imagine how you would wash yourself over such a sink or take a bath, at the bottom of which there are traces of dirty water. Secondly, the hook-lock does not guarantee one hundred percent high-quality hose attachment. The latter can fly off the edge of the washbasin or bath at any time. This is fraught with flooding of your bathroom, as well as the premises of neighbors living on the floor below you. The drain hose, believe me, goes astray very often. It flies when the drain pump is turned on in the washing machine, during the spin cycle of the laundry (due to vibrations). In fact, you will have to sit near the unit for the entire wash cycle and make sure that the hose does not go astray. What then is the essence of the automatic machine, if you need to be near it all the time?
For these reasons, experts recommend (and strongly) to equip the drain with a siphon. Then you don’t have to worry about flooding your neighbors, as well as about the penetration of foreign odors from the sewer system into the room where the automatic machine is located.
The siphon is an elementary device. It is inexpensive, sold in any store that offers plumbing products. The siphon is usually mounted under the washbasin in the bathroom or under the sink for washing dishes if the washing machine is installed in the kitchen. The siphon must be mounted as high as possible. Setting it too low increases the risk of water backflow.
Connecting a washing machine
Drainage through the siphon is equipped independently according to the following scheme:
- Install a siphon. The device is installed strictly vertically. It is forbidden to place it horizontally due to the increased risk of leakage.
- Connect a drain hose to the installed siphon. The hose must first be raised by 0.6–0.8 m, fastened to the back of the washing unit (almost all machines have a special hook for this purpose) and only then lowered to the sewer drain.
- Connect the hose to the siphon fitting. It is optimal to perform this operation through a special cuff. It ensures complete tightness of the connection. If there is no cuff, you will first have to connect the adapter, pull it off with a metal clamp, and then connect the hose to this intermediate device.
Check all connections for tightness. Job done, drain done! Recently, special siphons have become widespread. They can be mounted on a wall surface. Such new devices are brought out with one side, and the other is connected to the sewer. A water outlet (cold) is mounted next to the siphon. This is done so that the process of connecting the washer is carried out as quickly and conveniently as possible. With such a plumbing "infrastructure", a new washing unit is connected to the sewer and to literally in 5 minutes.
There is an easier way to connect the drain hose to the water drainage system. It can also be done on your own. This technique involves inserting a hose directly into the sewer pipe, into which a special tee is pre-mounted.
Connected and ready to use washing machine
In this case, the drain is set up like this:
- Put a tee in the sewer system.
- Bend the hose in the form of the Latin letter S (thereby you cut off the unit from the sewer when the washer pump is turned off).
- Insert the hose into the tee and carefully seal the resulting connection.
All. Work completed. Your washing machine is connected to the sewer system.
