Plumbing equipment is subject to intensive operational loads and often fails. When the toilet cistern constantly flows, it brings great losses due to water overruns. It is not advisable to call the masters due to the failure of the device, since the repair mostly consists in setting up the tank mechanism. But in order to understand how to fix a toilet, you first need to know how it works. Let's figure out how to independently repair the toilet flush tank with a button.
Toilet device
The composition of the toilet includes the following elements:
- A toilet bowl connected to a sewer pipe with an airtight cuff.
- Drain tank with fittings that ensure its filling with water and draining.
A water supply hose is connected to the tank. Depending on the design, it is connected from the side or from below. The bowl and tank are usually connected to each other with bolts and a seal.
Hardware components:
- pull-rod trigger with drain button;
- a shut-off device (inlet valve) connected to the float;
- rubber seals.
The principle of operation of the toilet with a button
The toilet cistern with a button is a water seal filled with a portion of water that is fed into the bowl when the shutter is opened. Flushing is controlled by a button that must be pressed. This opens the valve, and the water under its own weight flows down, washing the bowl. After the tank is released, the shut-off valve at the inlet opens, the container is filled with the next portion to a certain level, regulated by a float. Access to the mechanism is provided by opening the top cover of the tank.
Preparation for repair
Before you fix the toilet cistern, it must be opened. It can only be accessed from above by removing the cover. In many modifications, it is attached with a ring around the button. This ring must be pressed and turned counterclockwise. After a long period of use, the ring may not turn. Then a few drops of oil are applied to the attachment site. After the ring turns, it is unscrewed, and then the button is released from the plastic clothespins and the cover is removed.
Do-it-yourself ways to repair the tank mechanism
Through the upper hole in the tank, the entire mechanism of the drain valve is visible. It may have the following faults:
- The tank is constantly leaking.
- There is no water pressure at the inlet.
- Uncontrolled drain mechanism.
The causes of these malfunctions can be different, and the way in which the toilet cistern will be repaired depends on them.
- The plug (pear) does not fit snugly against the drain hole. To avoid this, you should purchase high quality plumbing. The possibility of repair can be checked by pressing the stem with a little force. If at the same time the water does not flow, the cork can be slightly weighted with an additional load or the rod can be leveled. You also need to periodically clean the seal from rust and salts, due to which the tightness is broken, and the liquid constantly flows into the bowl.
- The regulator does not shut off the water supply. At the same time, the tank will never overflow, thanks to the presence of an overflow tube. The serviceability of each element of the device is checked: float, inlet valve, fasteners, rod. The failed part is replaced or the float mount is simply tightened.
- Leak from the tank into the room. It may have a crack or the tightness of the gaskets is broken. Particular attention should be paid to the quality of the connection between the current tank and the bowl. It needs to be tightened, and if this does not help, the rubber gasket changes. Another cause of leakage may be the wear of the cuff in the joint between the bowl drain and the sewer pipe. The seal is changed to a new one, having cleaned the connection of contaminants and treating the surfaces with a sealant.
- Weak pressure through the intake valve. This usually happens if it becomes clogged. You can prevent this by cleaning or installing a filter in front of it.
Inlet valve replacement
Before repairing the toilet, turn off the water supply tap. It connects to the pipeline from the riser. After that, the flexible hose is unscrewed from the intake mechanism. It can be easily removed by loosening the fastener. Instead, a new or refurbished one is installed. Assembly is carried out in reverse order. A plastic thread does not require sealing, and a fluoroplastic tape is wound onto a brass thread.
Bleed valve replacement
The main reason is the wear of the sealing ring under the valve. To replace it, you need to remove the hardware and install a new gasket. After the assembly is carried out in the reverse order.
The water release button should always be used carefully and pressed without sudden force.
Adjusting the water level in the tank
The water level can be easily adjusted by hand. To do this, the float is set in a certain position.
The optimal level is considered to be when the water supply to the container has stopped, and a few centimeters remain to its upper edge.
The method of adjustment depends on the design of the valve. The simplest is bending a metal bar. If the float moves along a horizontal plastic guide, it is fixed with the help of fastening elements in a certain position. With a vertical layout, it is moved with an adjusting screw.
When choosing the fill level, do not forget about the overflow pipe. Its upper edge should be a couple of centimeters above the water level in the filled container. If it is located lower, water will constantly flow through the overflow into the bowl.
Tank Troubleshooting
The tank may leak water due to a crack that has appeared in it. The same applies to the bowl. In this case, the question of how to repair a cistern or bowl is not worth it: the entire toilet is usually changed. A small crack in the upper parts of ceramic products can be repaired. So that it does not spread further, and the infiltration of water does not increase, it is drilled at the ends and processed along the entire length with sandpaper. The work is done neatly.
The surface is degreased, and the gap is filled with epoxy. After hardening, the seam is polished.
Built-in cistern repair (with installation)
It is more difficult to get to the mechanism of a tank installed behind a false wall. First of all, you should purchase a device with high reliability, which rarely requires repair. There should be inspection hatches in the wall through which you can get to the tank and replace the gaskets if the tightness is broken. Do-it-yourself drain fittings cannot be repaired due to the complexity of the design.
A coarse filter is installed in front of the hidden tank, which traps solid particles, which in most cases cause leakage.
How to choose the right plumbing?
When choosing a toilet, pay attention to the following.
- Way of fastening: monoblocks, compact and separate toilet bowls. The choice is made taking into account the size of the room, the design and the complexity of maintaining the tank.
- Accessories. Most of the parts with low strength and reliability are made of plastic.
- The presence of positive reviews, a well-known manufacturer, the availability of a guarantee and a certificate.
Any toilet bowl, from the point of view of sanitary equipment, is a part of the toilet, which is necessary to maintain a certain level of water. The water accumulated in the device is used for flushing, and the built-in mechanism is responsible for dosing the flush and limiting the capacity of the container.
A significant part of modern tanks is equipped with a push-button system. One or two buttons are quite often characterized by interchangeability without sacrificing performance. How does a toilet flush tank with a button or two work?
The action of any tank is based on the functioning of the systems for collecting and draining water. The set is due to the operation of the intake system, which regulates the progressive filling. The inlet, regardless of the type of drain equipment, is of the same type and consists of a float that allows you to adjust the intensity of filling the system with water.
In the process of draining water, another valve is involved, which allows you to control this process. This design is varied. Certain positions of the outlet valves make it possible use dual mode and emergency drain.
One button
You can see a diagram of a toilet with a button in this illustration:
A plastic or metal float regulates the opening of the ball valve which helps water flow into the tank. The volume of incoming water is controlled by a diaphragm, which is equipped with a special lever device that regulates the pressure of the water jet.
Drain is regulated by means of a siphon, whose location is the central part. To fix the siphon to the outlet system, a “saddle” is used. A drain button is fixed on top of the entire structure.
A standard siphon can be provided with a split design that allows perform the cleaning process on the upper part only, and the lower part is simply washed.
With two buttons
Invisible elements of the two-button system are presented plug, float valve and drain fitting. The visible part of the design includes a cover and buttons.
The cistern device with two buttons is different high level of economy. Water consumption is reduced due to the possibility to provide a minimum drain or completely empty the volume.
An illiterate installation provokes the operation of two buttons as one, with the same volume of drain. A properly installed mechanism is characterized by a small drain at the level of 2-4 liters, and about 6-8 liters of water are spent on a large drain.
The difference from the design of the toilet cistern with one button lies solely in the design of the outlet valve.
It is impractical to install such fittings on small devices. If replacement is necessary, any hydraulic system of a suitable size can be used.
The principle of operation of the drain mechanism
The operation of this mechanism begins with pressing a button that is associated with the internal elements of the drain system. Up to this point, the tank is already filled with water to a regulated level and the entire volume is held by a rubber bulb. Such material contributes to a fairly tight fit to the saddle. Pressing the button causes a pull that repels the bag from which the drain hole opens.
After returning the button to its original position, the hollow and air-filled pear does not immediately return to its place. As it fills with water, the pear becomes heavier, lowers and fits tightly on the saddle. However, for the full functioning of the pear, a special pipe is important, which regulates the action of various forces on this rubber element.
Comparing the advantages and disadvantages of both options
One-button drain hydraulic systems belong to the category the most popular. Automatic two-button mechanisms are only gaining momentum in popularity.
The "small drain" hydraulic system is undeservedly underestimated. However, modern types of tanks are equipped with a special element - an auger that makes the water fall down intensively and powerfully, which positively affects the cleanliness of the toilet bowl.
If desired, there is a need to purchase economical one-button drain tanks in which water flow control is carried out using the Aqua-stop design. Profitability is due to the alternation of pressures: the first pressing contributes to the drain, and the second - stops this process.
Flushing tanks operating in a dual-mode drain save almost twenty cubic meters of water per year, which significantly affects the payment costs. Indeed, it should be taken into account that modern two-button mechanisms are more expensive than the classic one-button version, but all costs quickly pay off.
The main disadvantage of two-button products is the need to perform a number of rather complex adjustment and finishing works during the installation process, which makes self-assembly quite difficult.
Types of major breakdowns
The most frequent breakdowns during the operation of toilet bowls occur in the process of failures in the functioning of the systems for collecting and draining water. Imbalance contributes the formation of leaks of varying intensity. Such problems are solved by replacing individual parts or the entire system kit.
It should be remembered that the durability of the inlet elements directly depends on the quality characteristics of the incoming water. Experienced Specialists recommended to install filters.
Minor failures include broken buttons. In most cases, such failures can be eliminated by flushing the membrane to remove blockage. Such manipulation belongs to the category of simple and is easily performed independently.
In addition, the most common malfunctions include:
- Inability to fill the tank.
All incoming water flows out through the drain or overflows through the internal overflow. This situation most often occurs when the pear does not fit tightly to the drain, or if the rubber part of this element has worn out.
In two-button systems, water can constantly leak out if the gasket or membrane fails. If a leak is observed at the junction of the supply pipe and the tank, the most likely cause of the problems is damage to the seal. - Toilet flush button not working.
The problem may be due to the separation of the lever mechanism of the drain tank from the button and the release of the hooks from the attachment points.
Especially often there are problems with devices with a lower water supply which may be due to the following circumstances:
- insufficient water pressure under the conditions of the installed membrane filling valve, stimulating a constant flow into the tank;
- incorrect position of the inlet valve at which the elements are in contact with the walls of the device;
- float position not adjusted or violated which causes water to flow through the overflow pipe into the toilet bowl.
The most serious breakdowns are impractical to carry out on your own. Especially if there is a need to change the entire trigger valve system. A timely call to a plumber can save you from quite serious consequences and will certainly save time and effort.
It is impossible to imagine a home without a well-equipped bathroom. And the main thing in it is a toilet bowl with a drain tank.
The toilet tank is an integral part of this plumbing device, without which it simply loses the meaning of its purpose. The insides of the toilet cistern allow you to remove human waste products by supplying a dosed portion of water and refill the container.
The importance of this sanitary equipment in the toilet can be fully appreciated only if the toilet bowl is broken and it is impossible to use it.
Drain tank - internal structure
In the process of improvement, many designs of these products were developed and applied. By location, drain tanks can be classified as follows:
- Upper- is located at a height of approximately one and a half meters above the toilet bowl, water is supplied through the pipe after exposure to the hanging handle. By pulling on it, the drain valve is opened, and a portion of water enters the bowl.
- Hidden. The container is placed in a niche, which is arranged in the wall of the room. The start button with this option is located on the vertical plane of the partition (door). They are usually made from plastic.
- Compact The cistern is attached directly to the toilet bowl. To do this, it has a special shelf with holes. Fastening is carried out with screw parts; for faience products they are made of plastic.
Toilet bowls can be made from various materials:
- Cast iron. Cast products from this material are the original ways to produce toilet bowls. Currently, their use is not relevant, but the demand still remains, so they are still being produced. Cast iron products are often decorated with decorative cast elements. The material itself is durable and reliable. (See photo 2.)
- Ceramics. The most popular material for the production of sanitary ware at present. Products are durable enough with a clean smooth surface that is easy to wash and clean. It is not recommended to use powders and pastes with abrasives for this.
- Plastic. These plumbing fixtures are produced by stamping from various polymers. The advantage is high manufacturing precision, when mechanical reworking is practically not required.
Products made of polymeric materials are used, as a rule, for concealed installation, so their width is smaller than that of products made of other materials.
The internal structure of the drain tank
When installing a new cistern toilet, the first thing to consider is this is the completeness of the purchased equipment and its size. If the condition of the bowl is determined purely visually in order to establish its integrity, then the drain fixture is worthy of closer attention. It must not only be installed correctly, but also configured to work optimally. This can result in significant savings in terms of water consumption.
Today, the building materials market is filled with a mass of various products in terms of material and internal filling. If desired, you can find plumbing of outdated designs, if needed.
The design of the internal device of the drain tanks is almost the same with a slight difference from different suppliers:
- Mechanisms that include a stop button. The water will be drained until it is pressed or the entire volume will flow out. If you release the button earlier as you clean the toilet bowl, the liquid stops flowing into it.
- Drain devices with two buttons. When one of them is pressed, the entire volume of water is poured out, and when using the second, part of the liquid is poured out, depending on the flow rate adjustment. It is impossible to confuse the buttons - they are of different sizes. They appeared on the market relatively recently and this is due to the need to save water resources and, as a result, their own money.
- Two regime drain mechanisms.
The tanks differ in the nature of the flush:
- direct - while water flows into the bowl directly from the tank, in one direction;
- reverse - when flushing, water can change the direction of inflow, which cleans the toilet bowl more efficiently, although this creates noise.
A typical layout of a toilet cistern resembles an ordinary water seal, which includes a float and a system of levers. When using a button or pull (for rod mechanisms), water flows from top to bottom, cleaning the toilet bowl.
In this case, the float goes down and, through a system of levers, opens the inlet valve, through which water from the water supply network enters the tank, filling it for later use.
The internals for the cistern include:
- Inlet valve.
- Float.
- Siphon.
- A system of levers for moving parts and components of the mechanism.
Inlet valve
This node from various manufacturers is represented by a variety of design solutions, but the essence is the same for everyone: it is a drive valve on the water supply system, operating under the influence of force from the float.
When the float is lowered, the piston opens, and water enters the tank through the pipe.
As it fills, the float rises and moves the piston outward with a lever, gradually closing the nozzle. At the same time, water flows more and more slowly, and when the cross section is completely blocked, its flow into the tank stops.
Float
This product is a rubber or plastic container, the purpose of which, in accordance with the name, is to swim. At the same time, through a metal lever it opens and closes the intake valve.
Siphon
This is a device for volley discharge of water from the tank into the toilet bowl. The siphon for the toilet bowl is activated when the drain button is pressed, as a result of which a vacuum is created in the air chamber.
Under its influence, water is actively pumped out of the tank until it is completely empty.
Overflow device - common breakdowns and their repair
It is normal to fill the tank to 80% of the entire capacity. This is achieved by adjusting the intake valve, or rather the position of the float.
However, there are situations when a malfunction occurs in the operation of the locking device and the toilet bowl overflows. In this case, the overflow of the tank is inevitable and the water is poured onto the floor.
To avoid this situation, an overflow pipe leading to the drain is installed in the tank. When the liquid level rises above the norm, it flows through the pipe into the drain, preventing flooding of the room.
Watch the video
However, such a situation, when water flows out of the tank without stopping, is a sign of a malfunction and a reason for immediate intervention to eliminate it. Given current trends in the production of plumbing, it seems that it will not be necessary to restore the performance of a broken node, but it is necessary to replace it completely.
But the replaced node will still have to be disassembled in order to understand why it failed and eliminate the cause. For example, install an internal fine (coarse) filter at the inlet to the tank.
Another reason for the constant spillage of water may be a violation of the tightness of the locking mechanism due to gasket wear. It just needs to be replaced.
In general, water leakage into the toilet is a typical breakdown of this device. One of the reasons may be damage or wear on the insides of the drain tank siphon membrane. With such a malfunction, the siphon membrane will need to be replaced, and this can be done in the following sequence:
- Drain the water from the container. To prevent filling the container through the inlet valve, the float must be fixed in the upper position in some way, and it is better to close the ball valve at the water outlet.
- Loosen the nut securing the drain tube.
- Loosen the siphon nut located at the base at the outlet of the tank.
- Disconnect the siphon from the fluid release lever and remove it.
- Remove the membrane and replace it with a similar one.
- Reassemble the mechanism in reverse order.
During operation, it is necessary to inspect other insides for the toilet and correct where necessary. At the end of the work, you need to fill the tank and make several test runs of water to make sure that the problem has been eliminated.
It is also necessary to check all joints in the system for leaks. If any are found, take steps to eliminate them. When this fails, it is necessary to invite a qualified plumber to fix leaks.
What to do if the toilet tank does not fill
Watch the video - what to do if there is no water
This is one of the typical problems with the toilet flush system. When it occurs, you should not run to the store for a new tank. Let's try to understand the situation on our own, acting according to the following algorithm.
- Remove cover.
- Check float position. In some cases, the cause of the malfunction is its distortion, which prevents movement inside the container. It is necessary to restore the position, fill the tank and make a test descent of the liquid.
- Check for water in the plumbing system on other consoles.
- Close the valve at the inlet and unscrew the connection hose. Check to make sure it is not clogged.
- Inspect the hole in the intake valve body, if necessary, clean it from contamination with a nail or elastic wire.
- Check the piston stroke, if it is tight, it is necessary to remove and clean the surface of this part, achieving free movement in the housing.
Upon completion of these works, it is necessary to assemble the system back and make a trial filling of the tank two to three times. Usually, these steps are enough to fix the problem. If the filling of the container still does not occur, you will have to visit the plumbing store and buy a new valve.
Installation is in the reverse order. At the same time, we advise you to buy and install filters for tap water purification and install them immediately after the tap.
Establishing the fact that the toilet cistern has broken should not shock a person. Most faults can be fixed by hand. If this fails, call the emergency service - for a fee, they will easily fix any problem.
Installation and replacement of fittings
“Nothing lasts forever”, this fully applies to toilet flush devices. Sooner or later, you have to start replacing the fittings, that is, the internal structure of the tank. When deciding to do the work yourself, you need to take into account a number of circumstances:
- The very need for replacement implies a significant service life of your device. Therefore, when going to buy the insides, you need to at least roughly know the age of the device.
- There are many plumbing manufacturers and each of them brings its own design features to the device. Therefore, you also need to know the author of the product.
- The need for repair and doing it yourself requires certain knowledge and skills, as well as the availability of a special tool.
Installation of the insides of the drain tank is painstaking work, comparable to the assembly of a new product, so you need to treat it as carefully and responsibly as possible. Otherwise, leaks may form, the elimination of which is very troublesome.
Video - Rebar Replacement
It should be remembered that the inside of the tank can be a rather complex and fragile structure, the failure of which, if installed incorrectly, is very likely.
The difference in the insides of fittings from different manufacturers may depend on the method of water supply. There are such features.
- Lateral liquid supply provides for the location of the insides in the upper part of the tank, which is typical for domestic products. Such a system is the most economical, but the fluid supply is accompanied by noticeable noise. In more prestigious models, water is supplied through a tube, the end of which is lowered to the bottom and filling is done quietly.
- A device for supplying water from below is most often found on foreign-made models, but recently it has also been found on domestic products.
Drainage devices work by pulling the lever up or by pressing the button, which can be two for different dosages of water when flushing.
What principles should be followed when repairing
Watch video - internal structure and principle of operation
Before starting work, it is necessary to prepare the equipment. This means doing the following:
- It is necessary to turn off the tap on the water pipe in front of the inlet valve.
- Remove cover. You may need to unscrew the latch in the form of a button, usually located on the left wall of the container. Unscrew the fixing screw and remove the cover, gaining access to the inside of the tank.
- Inspect fittings for worn or broken items.
Inside the filling fitting there is a diaphragm valve or a piston seal. Any of these versions is sensitive to fine impurities, which are always present in tap water.
Settling on the walls of pipes and any surfaces with which it comes into contact, these contaminants interfere with the operation of valve mechanisms. The structure of this sediment is very strong, and it is removed only mechanically.
If filtering devices are not installed on the inlet pipe, periodic replacement of fittings is inevitable. You can abandon the push-button drain mechanism in favor of the stock one.
To install a new mechanism in the tank, you must first remove the old one. This can be done by turning it clockwise until it is completely disengaged. In this case, do not use excessive force, if the attachment point breaks, it will be problematic to remove it.
New fittings must match the size of the tank, you need to pay attention to this when buying.
Watch the video
It is also necessary to pay attention to the correct installation of sealing elements - gaskets. Their skewed placement can lead to additional loads and, over time, to the formation of cracks in the body, which is detrimental to ceramic products.
When installing fasteners, excessive force must not be applied to it so as not to create additional loads.
Installing the insides of the tank does not seem like a complicated operation. It is quite possible to do it yourself.
Conclusion
The main requirement for the operation of such plumbing products is the constant supervision of their work. Any deviation from the norm indicates certain changes in the filling of the device and you need to clearly understand the consequences of such changes.
The most dangerous phenomena are situations when water overflows above the permissible level. This is fraught with flooding of neighbors from below and real considerable costs for eliminating the consequences.

Currently, devices for connecting the toilet bowl directly to the water supply have appeared on the plumbing market. This eliminates the need for a tank as such. It should be thought that the future belongs to products of this kind.
Washing machines have long been indispensable household appliances for most people. But in order for them to perform their functions, moreover, uninterruptedly and in full, it is necessary to ensure the possibility of draining contaminated water.
The easiest way to do this is with a regular hose included in the package. However, it is more practical to use a siphon for a washing machine, which will provide a number of important advantages. We will talk about how to select and install an important and convenient sewer device.
The process of removing contaminated water after washing must be organized correctly. For this, an important device called a siphon is used, which is able to uninterruptedly ensure the draining of any required amount of liquid.
Moreover, at the same time with such an operation, a number of important tasks are performed, including:
- Preventing the ingress of odors, gases from the sewer into the premises. This is achieved by using a water seal, which is a water plug that completely covers the desired section of the pipe along the entire diameter. Moreover, this structural element performs its functions, even when the washing machine is not used for a long time.
- The exclusion of the formation of plugs in the drain system, and, if this does happen, the design of the siphon will provide an easy and quick cleaning procedure.
In addition, many siphons are capable of filtering large particles of debris. This additionally helps to prevent the possibility of clogging the sewer, requiring. Still, such a solution can save valuable items forgotten in the pockets of any washable items.
Any siphon for draining / draining water from a washing machine is a plastic or metal structure with a water seal that prevents odors from entering the housing
An important function is also considered to reduce the load on, which extends its life, and significantly. Is it mandatory to use it?
The washing machine is equipped with a drain hose with a device for forming a bend. It can replace the siphon, because. prevents the reverse flow of waste water, but at the same time, the contaminated liquid gradually spoils the enamel shell of the bathtub, sink or toilet bowl
Modern washing machines are equipped with drain hoses, which may well replace the siphon. The advantage of this method of water drainage is the ease of installation and operation.
Since all that needs to be done to prepare for the drain procedure is to run the hose into the bathroom, sink, toilet. Such a device is attached using a curved element - a holder attached to the hose.
If the indicated method has only one plus, then there are more disadvantages and they are more significant. So, if the hose is not connected to a sewer pipe, then the hose will have to be bent into an S or U shape.
The siphon does not have to be specialized, that is, the product for washing, dishwasher, which has an additional pipe for draining from the machine, will be able to drain contaminated water
As a result, the thin-walled corrugated product will be constantly under load. Which often leads to a violation of its tightness and related problems. And by abandoning the water seal, the owner of the washing machine runs the risk of saturating his home.
Often the distance from the washing machine to the outlet of the sewer pipe is impressive, and it is not possible to lay the drain hose correctly, that is, with a slope. As a result, the load on the pump increases significantly, which will lead to its premature failure.
When connecting a drain hose with a water seal formed by a bend in the pipe, it is necessary to provide a slope to improve the flow of water into the sewer
In addition, if the length of the existing hose is not enough, it is increased with the help of an additional piece of the same product and a coupling. Which also leads to an increase in resistance, which means an increase in the load on the pump.
Additional docking points for all parts of the drain hose are not sufficiently reliable and durable. As a result, a leak can start at any time.
While drain hoses are inexpensive and easy to replace, the fear of hurting yourself or your neighbors should keep washing machine owners from constantly using a hose, especially a misplaced one, instead of a siphon.
Due to these significant drawbacks, the use of a drain hose can only be a temporary solution. And it will be possible to properly organize the drain by connecting the washing machine to the nearest sewer pipe. If it is far, then it should be lengthened.
To connect the hose to the pipe, you should purchase a rubber cuff that levels the difference in the diameters of these products. In addition, this way you can achieve the desired tightness of the connection. In this case, the requirements of the instructions attached to the washing machine must be observed.
The laying of sewer pipes in a hidden way is quite rare in our country, because. building codes require free access to communications. However, the location of the connection point to the sewer behind a false wall is quite possible.
All of the above indicates that you can do without a siphon designed for, but this will not be the most practical and best solution.
Device selection guidelines
It is difficult to choose drain fittings only because of the low awareness of potential buyers with this type of equipment. But fixing this is not difficult, since there are only a few of its types, which greatly simplifies the task.
With the typical types of siphons used when connecting washers, the video will acquaint you:
These include the following siphons:
- outdoor;
- internal;
- combined.
Since each type has its own advantages and disadvantages, the interested person should familiarize themselves with them in more detail. This will help save time and money when buying.
The built-in type of siphon is installed in the wall. The product is usually supplied with an external decorative panel that allows you to hide the installation site.
Inexpensive and extremely unsightly
Typically, external siphons are used if a fairly large distance separates the washing machine and the nearest sewer pipe. This makes it possible to install in a convenient place and use for this purpose structurally simple products that are not distinguished by compactness or other technical delights.
An external siphon is used when there is no need to save space, and its unprepossessing features are not striking, for example, if it is hidden behind the washing machine itself, the bathroom
The disadvantages include the fact that external siphons do not make it possible to install existing washing machines close to the walls that people need. Therefore, in some cases, insufficient compactness can also be considered a minus.
Comfortable and affordable models
A feature of all internal siphons is their small dimensions and the fact that they are mounted inside the wall, for which special recesses are made. The above allows you to install washing machines close to any wall of the room.
In addition, internal siphons are distinguished by high aesthetic qualities. Their body is recessed into a pre-made cavity, and the outer part is closed with a decorative panel, which can be metal or plastic. Therefore, only the 90 °C curved compact fitting can be seen from the entire structure.
The use of a built-in siphon allows you to completely hide aesthetically unattractive knots. Outside, there is only a coupling or fitting for connecting hoses
The disadvantages of internal siphons are a relatively complex installation and a considerable cost compared to other types. In addition, they are much more difficult to dismantle, which causes some inconvenience when cleaning is necessary.
Universal combined option
Visually combined siphons do not differ from ordinary ones with the exception of only one moment. This is the presence in the design of several fittings, designed for the simultaneous connection of drain hoses belonging to various objects.
Such a product is versatile, therefore it is used for the simultaneous removal of contaminated water from washing machines, washbasins, kitchen sinks, dishwashers.
How to install a combined siphon is described in the following video, and it also indicates the advantages and disadvantages of this method of connecting to the sewer:
Differences in size and shape
For ease of use, all modern drain fittings differ in shape and size. This is done to ensure the desired performance, efficiency, clogging prevention, ease of installation, imparting sufficient aesthetic qualities, and other issues.
Siphons for arranging sewerage are now available in a wide range, which makes it possible to supply all points of connection of plumbing and household equipment to the sewer with a water seal
Therefore, if a potential buyer needs to save space when installing a washing machine, then you should pay attention to flat siphons. They have the most compact dimensions.
As a result, they make it easy to place the purchased washing machine under the existing washbasin. What is an effective solution, especially in small bathrooms. This type of installation can be an interesting design decision if a person chooses a matching appliance and sink.
The option of installing a washing machine under the sink requires the use of a special flat type of siphon, to which it is also possible to connect a washer drain
Check valve attachments
Although modern siphons successfully resist clogging, the formation of traffic jams, but anything can happen. Therefore, the buyer should take care of an additional degree of protection.
For these purposes, a siphon for a purchased washing machine with a built-in non-return valve is used. It is designed to solve a number of important tasks to ensure safe use.
Which include:
- Preventing the return of polluted waters when blockages form in sewer pipes.
- Exclusion of unauthorized draining of water during the washing process.
The presence of this valve is especially important for residents of the lower floors of houses. Since they are most affected by blockages in sewer systems.
The check valve is extremely simple in design, however, its use allows you to avoid the unpleasant phenomena of the reverse flow of dirty liquid into the pipes connected to the siphon
At the same time, a potential buyer of this type of siphon should pay attention to the fact that many washing machines are supplied with non-return valves already equipped. Therefore, in order to avoid unnecessary spending, this issue must be clarified in advance.
Preparing to buy fittings
To organize an effective washing process, you can use any type of siphon. The main thing to consider is ease of installation, use and aesthetic qualities. If the washing machine is located far from the siphon, and there is no question of saving space, then you can buy any of its varieties.
It is ideal when the drain fixture will be covered from view by something - a bathroom, a sink, a door, furniture, any other object. If the shapes of the siphon “hurt the eye”, do not add aesthetics to the room, and besides, there is no way to hide it, then you need to purchase a built-in product.
Such a solution will allow you to put the washing machine close to any wall the owner needs, to hide the drain fittings. This option will significantly improve the look of the room.
The combined siphon is the most versatile solution, as it allows you to connect any number of drain hoses to the sewer pipe
When it is planned to install under, then it will be right to purchase a flat siphon. It takes up a minimum amount of space, so it will easily allow you to complete your plan.
If a potential buyer plans to drain contaminated water simultaneously from 2-3 types of equipment, then the best solution would be to purchase a combined siphon that has the right number of fittings for connecting drain hoses.
If there is no check valve in the design of the washing machine, you should not save money on its purchase. The owner will not regularly benefit from it, but in a critical situation this product will save you from significant troubles and losses.
A flat siphon is the best option when the owner of a washing machine needs to save space in a bathroom or other room.
No need to save on the quality of the siphon itself, its components. Since their service life is always relatively short, and budget options remain operational for an even shorter period of time.
Installing Your Purchased Product
When installing a siphon yourself, you should always take into account a number of mandatory rules. Otherwise, it will not be possible to organize an effective drain of contaminated water, and this will also affect the performance of the washing machine.
The mandatory installation rules include the following points:
- the siphon cannot be installed higher than 80 cm from the level at which the washing machine is located - non-compliance entails a large load on the pumping device, which leads to its rapid wear;
- you should not extend the drain hose, such a solution will again lead to a significant increase in the load on the washing machine pump.
If you still had to perform an extension, then this should be considered as a temporary solution. The drain hose does not need to be thrown to the floor, as the pump will have to exert even more extra effort to perform its functions.
Therefore, the best way to solve the problem with the length is to connect the sewer pipe to the required distance.
The installation of any siphon is a simple operation, but this only applies to the situation when all preparatory work has been completed and communications have been connected
If this is not possible, then the hose should be laid along the wall with the necessary slope in order to ensure the gravity flow of water. In this case, the permissible loads will act on the pump, which means that the service life will not be reduced.
If you want to install the purchased siphon yourself, then you need to understand that this will be a simple operation only if the sewer pipes, sinks, washing machine, etc. are installed and connected. And the necessary preparatory work was completed, for example, a recess was made in the wall for a built-in siphon.
Installation and connection of the washing machine must be carried out in strict accordance with the manufacturer's instructions, the exact recommendations of which are given in the technical documentation for the product (+)
In addition, a number of features must be taken into account. For example, if the mentioned internal siphon is installed, and tiles are used to finish the walls of the bathroom, then the cladding is first performed. And only then a place for drain fittings is selected. Since work in the specified sequence will allow you to get higher aesthetic qualities.
If any of the above conditions is not met, then essential knowledge and a special tool will be required for installation. What makes the possibilities of an unprepared person limited.
Often mistakes are made that lead to financial losses. This indicates the need to use the services of craftsmen for complex work on wiring communications and other things.
The drain pipe from the washing machine must be connected to the sewer system at a strictly defined height, which may differ slightly depending on the brand of the machine, more precisely, on the capacity of the drain pump
Nevertheless, the usual replacement of the siphon or just the installation is quite simple to perform. Why you need to connect the product to the sewer pipe, and then bring the drain hose.
New gaskets must be used to ensure proper tightness. And after dismantling the old siphon from the sewer pipe, traces of contaminants must be removed from the hose.
After completing the installation procedure, carefully check the tightening of all available clamps, bolts, and other fasteners. Next, you need to drain the contaminated water in test mode.
Why toilet paper is placed under the siphon - such a simple solution will reveal even minimal leakage, which is not always possible to do visually. Therefore, verification should be carried out only using the specified method of control.
If a combined type of drain fitting is used, then it is worthwhile to simultaneously drain from all equipment in use. This will allow you to check the tightness and performance at maximum load.
This is how the drain hose is mounted to the sewer pipe, if there is a desire to save on the siphon, although this is not the best solution
If the testing did not reveal any leakage of the siphon to drain the contaminated liquid from the washing machine, then the owner can proceed to its normal use. And without any restrictions.
Conclusions and useful video on the topic
You can get acquainted with all existing types of siphons by watching the following video:
To choose the best option for a siphon, which makes it possible to uninterruptedly drain contaminated water from washing machines for a long time, it is enough to have a small stock of knowledge.
Since only a few types of drain fittings are produced and used by the owners of washing machines, which is quite enough to meet all needs. And also you should never forget that the siphon must be installed correctly.

When installing a brand new washing machine in his apartment or private house, each owner is worried about how to properly connect it to communications. And if we already wrote about how to connect the machine to the water supply and, now it's time to consider connecting the washing machine to the sewer.
The surest technology is to connect the drain hose directly to the sewer. The process requires effort and time, but we will tell you in detail how to properly connect the drain hose of the washing machine.
Connecting the washing machine: preparation
Any work related to technology requires serious and thorough preparation. And connecting a washing machine to the sewer is no exception.
If the washing machine is old, and you just reinstall it after moving, then you will have to buy something. Some accessories are included with new machines.
Preparation includes three stages:
- Decide on a place. It can be a bathroom - you must admit, it is convenient, since the drain is very close. The kitchen is also suitable, as the sink and sewerage are within reach. In rare cases, this is a hallway, when there is very little space in the kitchen or bathroom.
- Prepare your tools. You may need all or part of the list below:
- Screwdrivers - slotted and cross, different sizes (it is better to take a universal one with nozzles).
- If you have to cut into a pipe, then a special pipe cutter will not interfere.
- Welding for metal-plastic pipes.
- Siphon for connecting the washing machine to the sewer. Suitable for both regular and non-return valves.
- Plastic tee.
- Sealant.
- Rubber seals.
- Corrugated hose of the right length to drain the water (buy a new one or lengthen it if what the manufacturer provided is not enough).
Important! The drain hose should not exceed three meters in length so as not to create an unnecessary load on the drain pump.
Remove the shipping bolts holding the tank in place. Unscrew them from the back panel and close them with plugs. 
After going through all three steps, you can start connecting the drain hose of the washing machine.
Options for connecting the machine to the sewer
There are three most common options, consider them.
Through the siphon
Before you connect the washing machine to the sewer, you need to install the siphon on the sink. If the siphon does not have another outlet for the technique, then you will need a tee.
But there is one downside! If you connect the washer in this way, then a not-too-pleasant smell from the sewer pipe may enter the drum. 
To avoid this, your task is to take care of creating a so-called "air barrier" in the siphon.
Examine the siphon - on it you will find a small hole for a corrugated pipe. This pipe is bent so that when water stagnates, a “plug” appears in the bend. It is this cork that does not let sewer aromas into your machine.
Such a scheme does not complicate the discharge of water, and the plug is “updated” during each descent of waste water into the sewer system.
Through siphon with non-return valve
If you have purchased a siphon with a non-return valve, you can be sure that the washing machine is protected not only from odors, but also from contaminated water. With it, the drain will be much more efficient.
During the occurrence of a blockage in a conventional siphon, the wastewater returns to the machine on its own - the so-called “self-draining” process takes place. To protect the machine from this, you should choose a siphon with a valve.
Attention! After installing the siphon, connect the hose to the appropriate branch using a clamp.
without siphon
It happens that the connection occurs without a siphon - directly to the sewer pipe. For such a case, you will need to buy an adapter seal ring. It allows you to insert a thin hose into a fairly wide hole. The method is more complicated, but it will be relevant in two cases:
- There is no sink in the room.
- The machine is more than two meters away from the sink siphon.
In the photo you can see a visual demonstration of how to properly connect the washing machine to the sewer system without using a siphon adapter tube. It also shows how to connect the SMA through a siphon.
In any case, no matter how you organize the drainage of the washing machine - through a siphon or directly to the pipe, consider the distance between the drain point and the floor. The point at which the end of the hose must be located according to all the rules must be at least 50 cm from the floor and not more than 1 m.
Of course, the numbers may vary, given the power of the pump: the more powerful the pump, the greater the deviation from the norm.
The considered withdrawal methods are considered one of the most reliable. They will protect your home from leaks, and the aesthetic issue has been resolved - the hose is neatly hidden behind the typewriter or in the kitchen. Simple, harmonious, reliable.
Other ways to connect the washing machine to the sewer
But there are also not quite traditional ways to connect the washing machine - they are extremely simple.
You can throw the hose through:
All you need in this case is a small plastic hook with clips to hold the hose. 
Although the method is simple, it cannot be called reliable. Here are a number of disadvantages that you may encounter by choosing it:
- If the water pressure is strong, the hose may come off and water will flow onto the floor. The hose is attached so weakly that it can be torn off by a careless movement. Also, children or pets can “help” him fall.
- After each wash cycle, the bathroom, toilet or sink needs to be cleaned and washed.
- There is no mention of aesthetics. Washing dishes where water has just drained after washing is at least not very hygienic.
Please note! If such a drain suits you, then do not buy a hose longer than 4 meters. If the hose is too long, not all of the water will drain, but remain in the tube, wasting not too pleasant odors.
Now that you know all the schemes for connecting the machine to the sewer pipe, it remains only to choose the appropriate method and easily organize the drain. If you go the traditional way, do not save on components, and then your washing machine will thank you for years of flawless and trouble-free operation.
