Do-it-yourself toilet drain valve repair

In detail: do-it-yourself toilet drain valve repair from a real master for the site my.housecope.com.

The most common problem in bathrooms is the malfunction of the toilet bowls. Buttons sinking, slow filling of the storage tank, incessant leakage of water from an overflowing tank. What kind of malfunctions do not happen. These situations can arise for a variety of reasons. To reveal the true cause in each individual case, it is necessary to dismantle the cover. After determining the nature of the malfunction, you can perform a simple repair of the toilet bowl with a button with your own hands, without resorting to the help of plumbers.

We unscrew the drain button by hand, rotating it counterclockwise. No tools are required for this operation. We take out the button and carefully remove the cover.

There are two mechanisms inside the drain tank, in the details of which there may be a malfunction that causes a leak:

drain mechanism;
a shut-off valve responsible for the flow of water from the water supply to the tank.

We carefully examine the drain mechanism, evaluating the height of the water level. If the water is in the overflow area, then this indicates that the locking device does not hold.

The water in it is above the float, and therefore reaches the drain channel, through which it drains into the sewer system.

If the water level is at the adjusted height in the locking device, then the leakage is due to a malfunction of the valve in the drain mechanism. These are the two main reasons.

Water passes above the overflow device, which means that the drain valve is in working order, and the problem lies in the constipation mechanism. We drain, freeing the container from water. Close the water supply valve to the system. We remove the drain mechanism device by turning it slightly counterclockwise. We take out the removed part from the container, inspect the condition of the sealing rubber ring, which is the shut-off valve of the drain mechanism. We are convinced of its integrity. Put aside.

If this is not the case, then remove the ring and rearrange it with the back side, thereby ensuring a snug fit of the rubber to the surface of the bottom of the container. You can immediately put a new o-ring purchased at a plumbing store.

The second problem is the formation of plaque, the accumulation of mucus on the surface of the shut-off valve, which violates the tightness of this system. It can be eliminated by cleaning the part from layers. Changing the ring is very easy. Remove the plastic lock washer. They take a rubber part, wash it thoroughly, then turn it upside down and press it with a washer installed in its original place.

We unscrew the water supply system and the locking mechanism. There are tanks with a lower water supply and with an upper one located in the side wall of the tank. The inlet hose is connected and the valve is on top. The type of connection does not play an important role, since the malfunction is directly related to the state of the shut-off valve. Grains of sand, rust from the water supply system can get under the valve, which violates the tightness of the locking ring.

In addition, the valve itself can be deformed during long-term operation. A manifestation of this is a specific recess formed on the sealing gum. A part with such damage can no longer restrain the flow of water from the water supply system.

Remove the mechanism that controls the flow of water into the tank. To do this, unscrew the large nut by turning it counterclockwise.
We take out the removed device from the tank, temporarily putting it aside.
We consider a membrane that serves to reduce the pressure of water coming from the system.
We wash the sealing ring, removed together with the membrane from the inlet pipe.
Next, we proceed to dismantle the body of the shut-off valve, which was put aside for a while.
First of all, we snap off the float, and remove it.
Then we remove the body of the float itself, moving the tongue, which fixes the position of the part in the tank, to the side.
Then we disassemble the installation site of the valve. To do this, we take a screwdriver, pick it up on both sides, removing the valve with a “toward” movement.
We examine the nest from which the valve was pulled out, and we see a small hole, which it should close tightly when the tank is full of water.
The deformed valve looks like a miniature rubber band, in the center of which a recess is extruded, the size of which corresponds to the size of the hole that passes water into the tank.
At the first repair, this rubber valve is turned over to the other side, which is smooth and even.
When re-repairing, this gum-valve is cut with a sharp clerical knife strictly in the middle. First, the first deformed part is placed in the nest, and then the second - with a smooth cut side up. Thus, one valve can be used three times, each time turning the parts with a flat surface to the hole through which the tank is filled with water.
You can strengthen the valve with an additional piece cut from dense foam.
We install the valve back into place in the socket, fixing it in position with pressure until it clicks into place.
We assemble all the parts in the reverse order: body, float, installation on the pipe, fixing the device with a swivel nut.
The valve in the raised position should extend the float 1 cm above the body in which it is located. It is in this position that it is necessary to fix the position of the float by snapping the locking mechanism.
We put in place the second part that closes the drain hole in the tank. With a sharp movement in a clockwise direction, we fix it in place. A characteristic click should sound.

Open the tap and start the water supply system. We monitor the process of filling the tank, paying attention to the moment of operation of the shut-off valve, which has been repaired. As soon as the water overflowed into the body of the float and raised it by 1 cm, the water supply to the tank stopped. We put the cover in place, and fix it with the water drain button, twisting it along the thread of the drain device part until it stops in the clockwise direction. We look at the result of the repair work. There is no uncontrolled flow of water from the cistern in the toilet bowl. The water meter froze, confirming that no water was being drawn from the system. We will make a control drain to once again verify the positive result of the repair. The problem was fixed by hand. Saved money by eliminating the need to purchase a new drain mechanism and shut-off valve.

You can learn more about repairing the flush mechanism of a toilet bowl with a button from the video.

If during flushing, trickles of water appear from under the tank, then this indicates a depressurization of the drain hole. A gasket is responsible for the tightness of the connection of the parts of the entire structure, which can be round or of a different shape, depending on the model. To correct the situation with the flow of water can only replace the seal. Before going to the store, you must remove the drain tank and get the sealing gum. It is better to show the removed part to the sellers, who will help you choose a good replacement for it.

Sometimes it is better not to buy exactly the same seal, as it will fail again after a while. Manufacturers produce consumables using the latest materials, the quality of which is superior to previous products. It is these sealing gum that is worth taking.Having installed the purchased consumable in place of the old gasket, the tank is installed in the reverse order. It has already been said above how to install the drain mechanism and inlet valve, as well as how to fix the tank on the toilet bowl.

The low rate of water entering the toilet bowl is associated with clogged filters. Repair work is carried out in the following order:

turning the faucet handle, we turn off the water entering the toilet bowl from the cold water supply system;
we unscrew the flexible connection from the water supply valve to the toilet, located either from below or from the side, depending on the model of the sanitary ware;
in a clogged hose, we eliminate the blockage and check the water pressure in the water supply by lowering the end of the flexible hose into the toilet, if its length is enough;
otherwise, we use a five-liter plastic bottle or canister to drain the water;
turn on the tap, if the pressure is good, then proceed to clean the water supply valve from accumulated debris;
this part is not available in all models of toilet bowls, but if it is, it needs to be cleaned;
we pull out the filter from the valve with the help of pliers, grabbing the part by a small pin;
we wash the removed grate in the sink under a stream of clean water from clogged solid particles and from accumulated mucus;
then we put the washed filter back in place, turn on the water and see if the problem is fixed or not.

If the problem is not resolved after washing the filter and the flexible hose, then we flush the entire water supply valve by removing it from the tank, after removing the toilet lid.

After all the steps described above, the problem is usually solved. The algorithm for repairing a toilet cistern with a button in the case of slow filling with water is clearly shown in the video.

In the old toilet bowl, we dismantle the old fittings that have become unusable and install a new water supply and drain system. We purchase universal fittings suitable for all toilet cisterns. For economical use of water, we buy a two-button drain mechanism that allows you to change the amount of drain depending on the type of human waste being washed off.In such fittings, the manufacturer uses:

dual-mode push-button mechanism;

manual adjustment of the volume of small and large water discharge;

drain mechanism rack adjustable to the height of the tank;

changing the thrust by reinstalling the lever in one of the existing holes;

clamping nut with rubber gasket;

a valve that closes the drain hole in the toilet bowl.

We will replace the old fittings. To do this, unscrew the button holding the toilet lid and pull it out of the socket. Let's take the cover off. Turn off the water supply to the tank. Disconnect the flexible hose. Unscrew the screws holding the flush tank to the toilet bowl. Remove the reservoir and place it on the seat cover. Remove the rubber seal, and then unscrew the clamping plastic nut by hand. Then we remove the old drain mechanism.Next, we put a new drain mechanism, after removing the rubber seal from it and unscrewing the clamping fixing nut. After installing the drain mechanism in the hole of the tank, we fix its position with the removed parts. When installing the tank on the toilet, do not forget about the sealing ring that is placed on top of the plastic nut. Then we insert the pins of the tank into special holes in the bowl, screwing the wing nuts on them from below. We tighten the fasteners evenly from both sides, avoiding distortion of the installed part. If necessary, replace the fasteners with new parts with sealing gaskets.When connecting the water hose to the side inlet valve, we hold the part inside the tank from turning. Tighten the nut with a special wrench or pliers. Install the tank lid, tighten the button. If necessary, adjust the rack, rearrange the lever.The two-button button has two pins, with which the desired drain mechanism is activated. The length of the pins reaches 10 cm. They are shortened to the desired length, depending on the height of the tank. Screw into a button. Insert into the cover and fix the position of the button from the inside with a nut. Install the lid on the tank. Turn on the water supply. Press a small part of the button, about 2 liters of water are drained. Press most of the button, about six liters of water are drained.

The toilet in every home is an element of everyday life, without which it is simply impossible to do. It is operated much more often than all other plumbing fixtures. That is why it fails more often than other devices. And its most vulnerable component is the tank, which consists of several internal components. Their mechanical damage, as well as careless handling of the tank are the reasons for the loss of this device of its performance. In the article, we will look at how to repair a toilet cistern with a button on our own, without calling a plumber team.

All drain tanks have a similar design. The difference is only in the mechanism of starting water.

Structurally, a toilet cistern with a button or two buttons, as well as a flush lever, can be represented as a set of interacting nodes:

filling valve. He is responsible for maintaining the water level at a certain level. The valve is controlled by a hollow float. When the water rises to the desired level, the float closes the water supply channel to the tank;
Plastic float attached to the filling valve. Works on the principle of a rocker, rising when filling the tank;
drain valvehaving an overflow system. Modern tank options involve controlling this valve by pressing a button. With manual control of the old-style drain, it is enough to pull the lever or chain to start water into the toilet;
overflow is a mandatory component of the tank. It is adjustable in height, thanks to which the maximum water level is set. When this level is exceeded, water flows through the overflow pipe into the sewer without spilling out through its walls.

The main structural elements and the principle of operation of the mechanism are the same for all types of drain tanks, only their execution differs

A tank with a mechanical drain is very simple to operate. Water enters it through the filling valve when the float is in the lowered position. After reaching a strictly defined level, the float shuts off the water supply. Drainage is controlled manually.If the tank is equipped with buttons, then the water is drained after pressing them. In this case, the drain valve partially or completely opens, passing water into the toilet. The float drops, slightly opening the filling valve.

The structure of the toilet flush tank with two buttons is a bit more complicated, but you can use such a tank more economically. If you press one of the buttons, the water is partially drained. Full drain occurs when the second button is pressed.

Increasingly, you can find new types of tanks that have bottom water connection. It is advisable to install them if the use of a side connection is not possible due to lack of space. The main difference between this tank is the presence of a membrane valve. Under the action of water pressure in the pipeline, the valve opens slightly and allows water to enter. When the water rises, the float presses on the piston rod, which gradually closes the diaphragm valve. When the set level is reached, the valve closes completely.

Fittings with bottom water inlet and button control

Drain malfunctions may well lead to the loss of the toilet bowl of its performance. For many, such a sudden breakdown can be a real natural disaster. In addition, no one will like the increased water consumption either.

Read about what a hygienic shower for a toilet bowl with a mixer is and what types it is, read in a separate material.

And how to choose a pump to increase water pressure and in what situations it is needed, we told in another article on the site.

What kind of breakdowns are typical for drain tanks? We list them in order of frequency of occurrence:

1. Leakage of water from the toilet to the floor. Most often, water flows through the sealing ring located between the bottom of the tank and the toilet shelf. If the ring is cracked or warped, water will seep through it. Also, the place of leakage may be the gaskets of the mounting bolts with which the tank is attached to the shelf. They will have to be replaced if tightening the bolts does not work. And it doesn't matter if the cistern of an old-style toilet bowl is being repaired, or a modern system is being repaired. After all, they all have the same mounts.

A high-quality sealing ring of the drain tank is the key to its good sealing.

Tip: When replacing gaskets and seals, it is recommended to lubricate them with liquid silicone to prolong their life and prevent cracking.

2. There is a constant flow of water in the toilet. Most often this is due to the overflow of the tank, in which water flows out through the overflow tube. This can happen due to a change in the height of the overflow, a loose fit of the float to the shut-off valve, and the loss of its tightness by the float. The rubber seal on the drain fitting may also be worn. Most often, the malfunction can be eliminated by adjustment. When the locking gasket is worn, it is desirable to replace the entire drain mechanism.

3. Starter malfunctions. If you are using a push-button water dispenser, water may not flow to the drain when the button is pressed. You can repair the fittings of the drain tank with your own hands, since, most often, the lever mechanism that connects the button to the drain breaks. This also applies to tanks with a handle or a chain.

4. Noisy tank filling. This happens due to the disconnection of the tube through which water is poured into the tank. This is typical for tanks in which water is supplied from the side. With a flown tube, the noise of incoming water will be clearly audible. To fix the problem, remove the top cover and install the tube on the fitting.

5. Water does not flow into the tank. Repairing a toilet cistern with a button or with other descent mechanisms in the event of such a problem comes down to checking the inlet to the cistern. It is necessary to remove the valve from the tank and clean the inlet with a thin steel wire and rinse it with water.

Many people who are used to old-style cistern do not know how to fix a toilet flush with a button. In fact, the differences between these systems are very minor. For many, the main problem is disassembling such a tank. Indeed, the button located on the tank lid requires careful handling during disassembly. But the device is very easy to disassemble.

To adjust the float, just raise or lower it slightly.

And if you are interested in how to install a shower cabin with your own hands, then we also have material on this topic.

Before buying a water filter, we recommend that you familiarize yourself with our tips for choosing them.

A tank with a bottom water connection uses a membrane-type filling valve. This may cause a problem with filling the tank with low pressure in the water supply system. The water pressure may not be enough to squeeze the valve and fill the tank. If low pressure is constantly maintained in your system, then it is better to replace the diaphragm valve with a rod analogue.

Another common problem is water leakage at the inlet valve reservoir. Its location is such that the valve is constantly under water. With insufficient tightness of the connections, the presence of leaks is almost guaranteed.

Repair of the toilet cistern with a lower water supply is carried out after shutting off the water supply and removing the cistern lid. After that, the problem is fixed using the same algorithms that are described for repairing models with buttons.

We figured out how to repair a flush tank with a button, with two buttons or with mechanical control. They differ slightly, mainly in the design of the control mechanism. The general principle of operation and repair for all considered devices is the same.

The video shows the repair of the toilet cistern with your own hands, or rather, the process of replacing its fittings.

Breakage of the drain tank is a problem that everyone has encountered. The first thing we do when we discover this trouble is to call the plumber. This is the right decision if you do not understand anything about plumbing and you do not have any tools in the house. But if your hands are growing from the right place, and there is a wrench in the pantry, then why not try to repair the cistern yourself? After all, doing repairs yourself, you save money and improve your skills.
How is the drain tank arranged, what kind of breakdowns does it have, and most importantly, to repair it? You will find answers to these questions in our article.Before proceeding with active actions, it is necessary to study a little theory and understand how water is drained in the toilet. Any model has two main parts: a bowl that stands on the floor or is fixed on the wall, and a water tank on top. This container is called the "drain tank".At the heart of the work of draining water is the principle of a water seal. When the lever (button) is pressed, the cork opens, and water is washed off into the riser by gravity.If you remove the lid on the tank, you will find a mechanism for draining water. It consists of a float, a seal and levers. It is conditionally possible to divide the mechanism of the drain tank into two parts: the water collection system and the drain mechanism.

When the button is released, the drain hole closes and water begins to draw in. The float controls its level and closes the valve at the right time.

Of course, depending on the manufacturer, the design is slightly different, but the meaning remains the same.

The principle of operation of the filling fittings is simple: when the tank becomes empty, it starts the flow of water, when it is full, it stops. A float is required to determine the water level. If there is little or vice versa, a lot of water, you can adjust the desired level yourself. It is recommended to use a volume of 5-7 liters of water.
The fittings that regulate the flow of water can be of several types.

With lateral water supply (fittings are located at the top). Basically, such a supply of water to the tank can be found in Russian-made toilet bowls. The mechanism is cheap, but very noisy. On more expensive models, a tube is attached to reduce noise, which supplies water to the bottom. Drain tank: side feed mechanism device
With bottom water supply. This type can be found both on foreign models of toilet bowls, and on domestic ones. Thanks to the mechanism, the noise from the water is minimized.

Push button flush mechanism
The drain mechanism is started either by pressing a button or by pulling out the stem. The most popular push-button version with a lever, which is shown in the photo. In toilets with a hidden cistern, the button is located on the wall. Therefore, the repair of a hanging toilet is less convenient: all actions are carried out after removing the button through a small hole. The video shows the process of dismantling the fittings from the built-in tank (installation).

The button mechanism can be one- and two-mode. In a two-mode drain, there are two buttons: one drains the water completely, and the second - half. This allows you to save water if necessary. Also, a similar mechanism can be implemented with one button, when the drain depends on the degree of pressing.
Image - Do-it-yourself toilet drain valve repair

First of all, let's examine the internal mechanism for defects. To do this, remove the top cover, usually it is fixed with a drain button. You need to either simply unscrew it, or pull out the button and unscrew the fastening screw.

Before repairing the drain tank, be sure to shut off the water supply.

After you open the lid, you will see several holes with a diameter of 1.5-2 cm for water supply (maybe only one). In one of them, filling fittings with a membrane valve will be fixed.

The membrane is very sensitive to water quality, so its service life depends on water filters. If there are no filters at all, then it is better to replace the mechanism with a Russian one with a stem valve.

Most often, the issue of repairing a toilet cistern can be solved by a complete replacement of parts. For expensive toilets, it is easy to find a repair kit with a sleeve and a membrane. On cheap models, it is more profitable to buy new fittings, they are not very expensive. The main thing is to choose the desired pipe diameter when buying, usually they are 10, 15 mm, as well as 1/3 and ½ inch.

Fitting kit for toilet repair

When replacing, it is necessary to make a sealed joint, so a sealing gasket is put on before fastening. The fittings are pulled together with a tank nut. Tighten them slightly, otherwise cracks may appear.

Decorative plugs are inserted into the remaining free holes. If necessary, you can change the position of the water supply. If the plug is simply inserted into the hole until it clicks, and does not rest on the nut, then no seals are provided in it, so water will flow out in the event of a malfunction.

At the bottom of the tank are holes for attaching to the toilet. Fastening takes place on metal or plastic bolts. Bolts made of brass and stainless steel are best suited for fixing the toilet bowl. Of course, ordinary metal fasteners are stronger than plastic ones, but they quickly rust. Before fastening, washers and rubber gaskets must be put on.

In the center is the largest hole for draining water. The shut-off valve for the drain tank is fastened with a cap washer through the gasket.

The most common failure is the continuous filling and leakage of water from the tank. The reason for this is the following factors:

float tilt;
the float mechanism does not work;
loose shut-off valve, old rubber seal.

The easiest way to solve the first problem, because in this case the toilet will not even require repair of the drain tank - just open the lid and adjust the float. Also, sometimes the shut-off valve does not fit into place, it is also enough just to put it manually into the recess.

The next problem is that the water fills the tank to the limit and does not stop. To check the mechanism, lift the float up to the stop. If the water does not stop, then the float mechanism will need to be replaced.

And the last point is the old sealant. It is very simple to determine such a breakdown: you just need to press the valve with your hand. If the water stops, you will have to replace the seal. Also, sometimes this is due to the too low weight of the locking mechanism. In this case, weights are added inside to make it heavier.

Another common failure is associated with a worn float. Its tightness is broken, and it does not float well, so the water in the tank does not rise to the desired level. You will need to replace the fittings of the drain tank, but you can also fix the float with your own hands. To do this, its hole is sealed with sealant, glue, heated plastic or any other material at hand. You can also look into a plumbing store, perhaps there will be an analogue of this float.

Not very often, but there are such breakdowns with the tank as: leakage of the tank mounting bolts and failure of the water supply valve. To eliminate them, it is enough to change the gaskets and buy a new valve.

Since residents use the toilet every day, the drain device may fail. But if this happened to your toilet and you don’t know how to change the flush mechanism in the toilet bowl, then let’s look at possible options for replacing or repairing the water drain device. Image - Do-it-yourself toilet drain valve repair

To begin with, let's look at the device of the drain valve in the toilet bowl, which you will definitely have to familiarize yourself with when it comes to replacing or repairing it. To get to the mechanism itself, you need to remove the lid from the tank. It can be attached in different ways, so we are not in a hurry, but carefully examine the elements that can fix it. Often this is one nut, which is located under the drain button.

Removing the lid is only the first step on the way to resolving the issue of how to change the drain mechanism in the toilet bowl.

After removing the cover, you will have access to the mechanisms responsible for draining the collected water. I advise you to do everything carefully so that after your intervention the device works well again.

The toilet drain fitting consists of three main parts:

- a drain mechanism with a button,

- the case on which the mechanism is installed,

- a plastic nut for attaching the body to the bottom of the tank.

Before you change the drain mechanism in the toilet bowl, it will be useful to get acquainted with the principle of its operation. The toilet flush device functions thanks to a system of levers and rods, which, when the drain button is pressed, raise the shut-off valve of the mechanism and release water into the toilet bowl.

There are two most common cistern flush valve systems. This is a simple one, designed to release all the water at once, and the other has a more complex system that allows you to release a small amount of water if necessary. This is done to save money. The second option, although more complicated, has one advantage - it uses water sparingly.

The flush mechanism in modern toilet bowls is made of plastic, only the valve has a rubber element. This is not strange, because they are designed to block water. It is these rubber parts that can deform or collapse over time, which will lead to water leakage, or any particle will get under the rubber, which will also cause the drain system to malfunction.Before you change the drain mechanism in the toilet bowl, it is necessary to carefully inspect it. If the mechanism is not damaged and when cleaning all the working elements it functions again, it is not worth changing it. But when the mechanism cannot be restored due to damage to the valve or breakage of the plastic part of the device, which is no longer in production, then the entire assembly will need to be replaced.

The main reason for replacing the drain mechanism is the duration of use. That is, the mechanism is outdated and beyond repair. The duration of the service life is affected by water and the activity of using the drain system.

To replace the drain mechanism, you need to remove the cover and see how it is attached. You must first turn off the water, otherwise it will flow into the tank non-stop.

The next step is to try to unfasten the mechanism, which in most cases is attached by snapping the mechanism onto the plastic barrel. This is done to simplify the maintenance of the structure. The drain mechanism is unfastened by turning it counterclockwise. When you manage to remove the mechanism, you can examine it and repair it if possible, but it's better not to skimp, because this device is inexpensive. Therefore, take the seized device as a sample and go to the store to purchase a new one. Having found an identical drain mechanism, adjust it in the same way as before and install it in place.

Now you have an idea of how to change the flush mechanism in the toilet bowl, but what if you can’t get exactly the same flush mechanism? Then you will have to install a drain device of a different design, and for this you will most likely need to dismantle the toilet bowl.

If you have not yet been able to resolve the issue of how to change the drain mechanism in the toilet bowl due to the difficulty of dismantling it, then you will need to remove the tank. In this case, it is necessary to block the access of water to the toilet, disconnect the inlet valve or float from the water supply. Next, find the fixing screws and unscrew them. Now you can remove the tank and replace the drain mechanism.

Free selection of a qualified plumber in your city!

To do this, dismantle the body of the old drain device. Then, inserting the body of the new mechanism into the tank, fasten it with a plastic nut. Do not forget to install a gasket between the body and the tank.

Moreover, I recommend smearing the gasket on both sides with sanitary sealant. Thanks to this, you will get a reliable connection.

The next step is to install the tank on the toilet. To do this, we also use a gasket treated with a sealant. Having installed the tank on the toilet bowl, we evenly attract it with the help of screws. Mounting screws are more conveniently tightened with a tubular wrench.

Having completed the installation of the tank, we adjust the drain mechanism and fix it on the body of the device. Now it remains to connect the inlet valve, cover the reservoir and put the drain button.

As you can see, everything is not so complicated, the main thing is not to rush, understand the design and its features. Since the manufacturers of toilet bowls are different, respectively, the configurations of the mechanisms for draining water are different.

I hope, dear readers, site helped you figure out how to change the flush mechanism in the toilet bowl and, if necessary, you can do it without outside help. Read also:
