Disassemble the built-in tank. How to remove the flush tank from a toilet at home: detailed recommendations

The most common problem that has already bothered thousands of our compatriots is the breakdown of the drain valve of the drain tank. Such a breakdown entails constant leakage of the tank. And when this happens, water bills immediately increase.

So that you do not have to overpay for central water supply and plumbing services, you can fix the breakdown yourself by opening the tank lid.

However, modern toilet models are not as easy to disassemble as older designs. On the upper surface of the toilet cistern there is usually a solid or separate button, which does not allow you to quickly open the lid as you would like.

Don't be fooled by claims that new models like these are impossible to disassemble. Yes, it may be difficult, but you can understand it in detail; you will understand the new design of the tank as quickly as the old one.

Open by yourself

An old toilet model will not present any difficulties for you: just lift the lid and unscrew the fasteners at the top of the flush mechanism.

Removing a toilet lid with a button is a more difficult task. So that you don’t have to resort to the help of strangers, we’ll look at ways to open the toilet tank yourself.

Among the available tools, prepare a slotted screwdriver, that is, a flat one, and another metal object with a flat tip.

How to disassemble a toilet cistern: instructions on working with various structures

A toilet tank is a storage tank into which water is collected in order to flush feces from the bowl of the vessel into the sewer at the right time. The tank itself has a simple design.

When people are interested in how to disassemble a toilet cistern, their interest often concerns disassembling the mechanism that is inside, or dismantling the cistern as a separate element of the entire structure.

Drain tank: dismantling and disassembling the mechanism

There is a water supply and level control system in each toilet tank. Modern toilets are equipped with mechanisms of a rather complex design.

Apartment owners use (and dismantle, if necessary, repairs) both outdated models and technically advanced ones. The disassembly process can be carried out directly on site - without removing the tank or after dismantling the latter. Which option will be used depends on various factors.

Usually dismantling is carried out for the purpose complete replacement tank along with the mechanism for a more advanced model. The storage tank must also be removed in case of water leakage at the connection points with the toilet. For example, due to wear of sealing gaskets, breakage of fastening bolts, and the appearance of microcracks in the housing. Let's look at how the toilet tank is removed in any of these situations.

Removing the water reservoir on the toilet

The classic design involves fastening the toilet cistern with just two studs or bolts (d = 5-7 mm). Typically, metal (bronze, brass, steel) studs with double-sided threads for nuts are used as fasteners. Steel fasteners were used on older models. The service life of steel fasteners is relatively short. Sometimes such pins “burn out” from rust after a year of using the device.

Fastening to the base of the toilet is usually done through two holes (or through 3) made in the bottom of the tank. The same two holes, in the same axes, are on the rear extension shelf of the device.

Fastening pins are passed through the aligned holes, gaskets are put on them on both sides and tightened with nuts. The cavities of the tank and toilet bowl are united by a common pipe, insulated at the junction with a rubber sealing ring.

The problem of how to remove the tank from the attached toilet shelf is solved as follows:

1. Close the centralized water supply valve.
2. Disconnect the water supply hose.
3. Empty the storage tank by pressing the drain button.
4. Unscrew the drain button head and remove the top cap of the reservoir.
5. Collect the remaining moisture inside the tank with a sponge.
6. Unscrew the nuts on the mounting studs (on the bolts) under the attached shelf.

Now all that remains is to carefully lift the tank, separating it from the installation site (possibly with some effort, because sometimes the gasket sticks) and then move it to the place where you plan to perform further work.

Disassembling the drain mechanism

Modern models in the mid-price segment usually use a push-button mechanism for double water flush (3/6 liters). One press of any button switches on the operating mode of the drain and fill modules. You can come across a variety of versions of such mechanisms. However, the assembly configuration for them is the same:

• head with buttons and threaded part for the valve mechanism;
• valve mechanism with lower threaded part;
• sealing gasket;
• valve mechanism fastening nut.

When the top cover is removed, the head with the buttons will already be twisted. All that remains is to remove the sealing gasket from the fastening nut. The gasket (rubber ring) has a pentagon-shaped or circular inner area.

The fastening nut has the same shape along the outer border (not always). When assembled, the sealing rubber ring is placed on the nut. It is removed and the nut is unscrewed. The released mechanism can be easily removed. The filling system is attached using the same method.

The material used for making the fittings is plastic. If repairs are necessary, the mechanism is disassembled, but it is easier to buy a new one to replace it.

How to remove the tank cap

Again, returning to modern toilet models, it should be noted that users are often faced with the problem of how to remove the lids on such models?

Indeed, these designs are somewhat different from outdated toilets in that they are made more technically, including the fastening of the lid. But in general, the principle remains the same - the cover is pressed with a nut included in the valve mechanism kit.

On new models, heads with buttons, bottom-button and double-button, act as a clamping nut. To remove the one-button fastener and remove the cover, follow these steps:

1. The button is pressed as if draining water and held in this position.
2. Carefully turn the head with the button counterclockwise.
3. Finally, turn the head with the button out of the valve mechanism bushing.

On different models threaded connection may vary. There is a wide-field external bushing thread, as in the picture below, and there is also an internal bushing thread for a small diameter rod.

Along with single control buttons, the head of which simply unscrews, there are designs that are more difficult to disassemble, made with latches. Often this solution has two-button mechanisms.

How to disassemble a tank with two buttons

On toilet cisterns, where a flush mechanism with two buttons is installed, there are different fastening methods. With this configuration, it is sometimes impossible to simply unscrew the head with the buttons. In such situations, the disassembly technology is as follows:

1. You only need to press one of the buttons (small) into the head body.
2. On the opened inner wall, a small groove will open in the lower part.
3. Using a screwdriver, carefully press the retainer through this groove.
4. Remove one button (large) from the case and then the other in the same way.
5. Unscrew the fixing screw located under the buttons.

After these operations, the tank lid with two buttons can be removed without any difficulty.

There are also tank designs where, first of all, you need to unscrew the decorative nickel-plated washer, then turn the lid 90 degrees - that is, install it across the container. In this position, press out the fixing brackets located inside the button head bowl. After these manipulations, the cover is completely freed from the fasteners.

Removing an old toilet cistern

A number of outdated toilet models are still in use. It is necessary to repair battered products more often due to significant wear of their components. But the owners of such structures do not have to think much about how to repair or remove the toilet cistern, due to the extremely simplified design.

So, to dismantle the same cover, it is enough to twist the handle on the drain mechanism rod and unscrew the plastic (or metal) washer nut. Under the lid inside the tank there is a float mechanism for collecting water and a lever-valve drain mechanism. The valve system of such a mechanism is usually attached to the tank through two additional holes in the bottom.

The tank itself of the old design is removed in the same way as is done with new models. It is necessary to unscrew the two bolted connections in the area of ​​the bottom of the tank. The passage area for water from the storage tank to the bowl on old toilets is isolated with an ellipsoidal sealing ring. Often in older systems there are overflow tubes secured at the bottom of the tank with a plastic nut.

To dismantle the lever-valve drain mechanism, you will need to unscrew two more bolted connections that secure the drain mechanism's rocker arm. The water supply module is dismantled by unscrewing just one nut from the outside of the tank body.

First, you need to disconnect the water supply hose from the storage valve. It should be noted: there are models of tanks with water release levers embedded in the side wall. On such devices, the toilet lid is not secured at all - it simply lies, resting on the walls of the body.

Malfunctions that force you to disassemble the tank

Typical malfunctions that force disassembly are often:

• leakage during flushing in the area of ​​the gasket at the connection between the tank and the toilet bowl;
• leakage in the places where the storage tank is attached to the toilet shelf;
• dysfunction of the drain mechanism;
• dysfunction of the water collection mechanism.

Leakage problems are often eliminated by simply tightening the fastening nuts. The functionality of the drain and set mechanisms may be impaired due to insufficient water pressure in centralized system. Therefore, before you start disassembling, you should make sure that there are no other possibilities for eliminating defects.

Defects in functional fittings

If there is an involuntary flow of water from the reservoir into the toilet bowl, most likely the lock ring is defective. It needs to be replaced. The same effect can be observed when the closing mode of the mechanism does not work. Possible reason– control button jamming.

Insufficient filling of the container with water indicates some defects in the dial module. Often the cause is the displacement of the float on the limit bar or its contact with other parts of the mechanism (the wall of the tank). A complete lack of drainage is possible due to a non-working dial module or drainage mechanism.

Plumbing care

When disassembling plumbing fixtures, each user should remember the principles of ceramic care. This has a direct bearing on repair work.

Ceramic products are resistant to impact chemical substances, but are easily damaged by cleaning with metal mesh, abrasives and other similar substances. Cleaning household plumbing after repairs should be done with soft substances and materials.

A few practical tips will help you cope with self-adjustment of fittings.

Briefing before performing repair work household appliances with your own hands is a voluntary matter. However, extra information never hurts in any endeavor. The more information there is about a specific object, the simpler and easier it is to perform all actions. Disassembling modern toilets, despite the simplicity of the steps, also does not exclude reference to the instructions.

How to disassemble a toilet cistern: disassembly instructions

Instructions for disassembling the toilet cistern

The most “complicated” component of the toilet is the flush cistern. But like any drainage mechanism, it has its own resource and eventually fails. Problems with the tank can be serious or not very serious. In the first case, it is best to call a plumber, in the second, you can try to solve the problem yourself. To determine the breakdown in any case, it is necessary to inspect the drain mechanism, and for this you need to know how to disassemble the toilet tank.

On a ceramic cistern with a side water supply, the lid can be removed very easily; you just need to unscrew the water release button or lever.

Most often, problems are associated with water leaks. Water may flow into the toilet bowl or directly onto the toilet floor. Sometimes, due to a breakdown of the mechanism, the tank itself stops filling with water. At the same time, neither a cheap nor an expensive toilet is insured against such malfunctions.

Regardless of the cost of the toilet, the fundamental design of the tank always remains the same.

The drain tank device consists of only two units: shut-off and drain valves. These units may differ in design, but always perform the same function.

Tank drain device

Diagram of a toilet with a flush cistern.

As already mentioned, all waste tanks have a similar structure and differ only in design. What does a toilet flush cistern look like?

A cistern is primarily a container that is filled with water. It can be ceramic, plastic or even metal. Moreover, a container made from such materials can take on a variety of shapes, and this container is covered on top with a lid made from the same material as the tank itself. A button, lever or handle, which is connected to the trigger mechanism of the flush tank, is responsible for draining the water.

The main “insides” of the tank include fittings, a float, a siphon, a diaphragm and a jet adjustment lever.

Any internal mechanism consists of only two fittings: locking and drain. The shut-off valve is responsible for filling the tank with water. It is the locking mechanism that shuts off the water that enters it and is activated at the moment when the tank is completely filled with water. The second drain valve is a mechanism that is activated when the release button or lever is pressed.

The cistern has a standby mode. In this mode, the container is completely filled with water to the specified level. The mass of water presses down on the rubber bulb, which, with its elastic surface, presses tightly against the saddle, thereby preventing water from passing through. Thanks to the column, the water remains in the tank. Then, to drain, depending on the design of the tank, you need to pull the top handle, press the button or pull the lever. The drain hole becomes open and water begins to flow freely into the toilet.

Instructions for disassembling the toilet cistern

Diagram of the drain tank.

Before disassembling the tank, you must first turn off the valve supplying water to the toilet. Then drain the water that is in the tank. Pay careful attention to old valves, which are often installed in apartment buildings. These rusted valves are very difficult to both unscrew and tighten. A broken valve can cause a flood. So if you can’t do it yourself, it’s better to turn to specialists.

Then remove the reservoir cap. If you have a ceramic one, be extremely careful, since ceramics are a very fragile material. Moreover, a broken lid will be difficult to replace; such individual parts are not sold on the markets.

If your toilet model has a side water supply, then the lid in such models can be removed very easily. For other types of toilets, there are other mechanisms by which the lid can be attached to the tank. Next, pay attention to the water release mechanism, namely the lever or button. If you have a button, you should unscrew it. Most buttons have a twist-out housing. And some buttons should simply be pulled out and the screw located under the button unscrewed.

After opening the lid, inspect the inside of the tank. If you need to remove the fill valve, you will need to unscrew the nuts. They are located on the hose that supplies water directly to the tank, and on the wall of the tank. The second nut performs the function of fixing the entire mechanism. The nuts can be unscrewed using a wrench or pliers.

Diagram of the principle of operation of the drain tank.

To dismantle the fill valve, which fills the inside of the tank with water, it is necessary to remove the nut on the hose supplying water and the nut on the wall of the tank that secures the entire mechanism. It is important to remember that the nuts should be unscrewed with an adjustable wrench or pliers.

In order not to break the base of the drain mechanism, it must be removed very carefully. To do this, turn the top of the mechanism counterclockwise and then remove it from the glass. Next you will find O-rings and gaskets. With their help, the mechanism is attached to the tank. To remove them, you will need to carefully unscrew them.

If you need to remove the tank completely from the toilet, it is not difficult to do. Simply unscrew the fastener that connects the bowl and tank. There will be a gasket between them. Disassembling the toilet is absolutely easy if you do everything in the right order.

Main causes of malfunction and their elimination

If the tank breaks or stops working correctly, then after disassembling it it is necessary to determine what the malfunction is and what causes it. Here are some of the most common problems:

A very common problem is the constant flow of water into the toilet. The reason for this may be wear of the membrane that is included with the siphon. Replacing the membrane is very simple; you need to disconnect the tank from the flush pipe and remove the siphon.

Diagram of the fittings of the drain tank.

If the water flows too slowly or, conversely, too quickly, the problem is in the float. Float misalignment is the simplest and most common malfunction. Moreover, to fix it, you will not need any tools or spare parts. All you need to do is lift the lid, move the locking mechanism so that the bulb snaps into place and shuts off the water. The float must close stop valve. If it doesn't, adjust it. To do this, bend the pin on which the float is attached to create a larger angle for the drain mechanism, which means it will operate when it is less full.

Even if the mechanism is working properly, time takes its toll, and the rubber bulb loses its elasticity. It becomes rougher, which leads to the fact that the place of contact with the saddle on the pear begins to crack, lose shape and become unusable. Over time, the bag no longer fits so tightly to the saddle. Water takes advantage of this and begins to seep through these cracks, forming a leak.

A rubber bulb cannot be repaired. So if you want to fix the leak, you will most likely have to replace it. However, a loose fit of the bag to the saddle can be caused by other reasons. For example, it could be dirt stuck to the saddle or a faulty trigger.

After fixing the problem, reassemble the tank in reverse order and make sure normal operation devices.

Self-repair of a toilet cistern with one or two buttons

Modern plumbing fixtures are quite reliable equipment. But, like any technical devices, sooner or later may also fail. And often this happens at the most inopportune moment. For example, when you come home from work in the evening, you suddenly discover that the toilet tank is leaking.

What to do? It's too late to call a plumber. And usually there is no need, because most of the malfunctions that lead to tank leaks can be dealt with on your own, saving on the labor costs of a technician.

But first you need to carry out diagnostics and determine the causes of the problem. First of all, to do this, you need to remove the lid from the toilet's storage tank.

general information

The most common design of a modern toilet is the “compact”, which involves installing the tank directly on the toilet. Control mechanisms were initially produced in two types: a ball attached to a retractable rod attached to a “bulb” - a rubber plug that covers the drain hole and a lever located on the side of the container.

Today, almost all manufacturers have switched to producing push-button models of tanks. There are two main types of these modifications:

• with one button;
• with two buttons or one button divided into segments.

The second variation involves a slightly more complex design of valves for controlling drainage processes, but pays off quite quickly due to the possibility of choosing one of the modes:

• when you press one button, the tank is completely emptied;
• when the second is activated, it is partial, which allows you to significantly save on water consumption.

How to open (remove the cover)?

Modifications are currently being made to allow the cover to be removed without any additional operations. The buttons are equipped with rods, transmitting force to the control elements of the tank fittings.

But most plumbing manufacturers continue to produce models that require some manipulations to remove the cover.

To remove the cover in one-button versions you need to apply moderate pressure on the ring surrounding the button and turn it in the direction opposite to the clockwise movement.

Next, you should carefully move the cover to a position perpendicular to its normal position, and carefully release the button block from the plastic clothespins. After this you can remove the lid from the tank and set aside.

To dismantle a cover equipped with a two-button block, it is usually just press any button, after which the technological groove on the adjacent button will become available. All that remains is to pick out this button and remove it, and then dismantle the second one. Then unscrew the fixing screw and remove the cover.

Basic breakdowns and repair methods

Before repairing a toilet cistern with a button, it is important to figure out what exactly the problem is. Regardless of the type of fittings for the toilet flush tank, There are three main problems with the operation of this plumbing equipment:

These malfunctions can occur for various reasons, depending on which it is decided how to repair a toilet cistern with a button:

1. Loose fit of the bulb (plug) to the drain hole. You can minimize the likelihood of such a situation occurring by initially purchasing reliable plumbing fixtures from well-known manufacturers.

Diagnostics is carried out as follows: after removing the cover, additional force is applied to the plug rod, pressing it against the drain hole. If the leak is fixed, the situation can be corrected by making the plug slightly heavier by hanging additional weight on the stem in the form of stainless metal nuts, for example.

If the leak does not stop, you should replace the plug or clean the surface of the drain hole from deposits problems that arise during operation (especially when using too hard water).

• It's also possible malfunction of the mechanism regulating the supply of water to the container. In this case, the constantly incoming water is discharged into sewer system through the overflow tube.

In this case it is necessary pay attention to the integrity of the reinforcement structural elements: rods, fastenings, float, intake valve and, if necessary, replace/repair them. Or simply adjust the position of the float, and then securely fix it.

• Leaking indoors is caused by two reasons: violation of the integrity of the tank itself or loose fit of gaskets in place threaded connections– at the junction of the cistern with the toilet or the outlet of the overflow pipe.

Sometimes it is enough to tighten a loose connection, but more often it appears need to replace rubber gaskets.

• Lack or insufficient water pressure at the inlet to the tank usually caused by a clogged intake valve. To avoid this situation, it is necessary to install a water filter before the connection point to the water supply system.

If such a problem occurs, you should unscrew the valve, first releasing all the water from the container and closing the inlet valve. Then clean the valve inlet a ton of wire or a sewing needle and rinse under running water.

Specific malfunctions of two-button models

To implement the principle of full/partial drainage, the fittings in two-button tank models are equipped with a diaphragm valve. When you press the economy flush button the lever prevents the valve cover from moving to the bottom position, which ensures partial emptying of the tank.

The main malfunctions of two-button tanks are:

1. Constant water flow. Occurs as a result of wear of the locking membrane. To fix this problem, you need to replace the membrane itself.
2. Recession of control buttons in the drain tank, which is the most common defect, usually appearing after a certain period of equipment operation due to wear and tear. To avoid this situation, do not use excessive force when pressing the buttons. You can fix the problem by removing the lid from the tank and returning the buttons to their normal position.
3. When the buttons are activated, nothing happens, that is, the water remains in the container. The cause of this problem is usually the breakdown of the elements of the lever mechanism or their separation. How to repair a flush tank with a button in this case? You can correct the situation by securing the hooks in the correct position or replacing broken parts.

How to regulate the water supply yourself?

The filling level of the toilet tank is regulated the same in all modifications - by setting the correct float position. Its correct position is considered to be one in which the flow of water into the container completely stops upon reaching a level that is a few centimeters short of the edge of the tank.

Depending on the design of the fittings, adjustment is carried out by bending the brass rod, sliding the float along the plastic guide, followed by fastening (if it is horizontal) or rotating the adjusting screw clockwise (if necessary, reduce the filling level) or against (if you need to reduce the maximum level) - for modifications with a vertical float layout.

The filling level of the container is also influenced by overflow tube position. Its upper edge should be located one to two centimeters above the water level in a completely filled tank.

In two-button modifications there are two such rods. To adjust the flush cistern of a toilet with two buttons, remember that one is responsible for performing a complete flush, the second activates the partial flush mechanism.

How to put everything back?

To put the toilet tank back together, the following operations must be performed:

• secure the fittings responsible for filling/draining water, using rubber gaskets where necessary;
• adjust the position of the float and drain valve;
• cover the tank with a lid;
• screw the push-button glass (in models with one button) or tighten the fastening screw and latch the control buttons - in two-button versions.

As can be seen from the above, nothing complicated about self-installation, repair and adjustment of flush cisterns for toilets with a button no. And for most people with at least some technical skills, it will not be difficult to carry out these procedures on their own, saving on calling a plumber.

Features of repairing toilet flush tanks with a button or two

There is a water supply and level control system in each toilet tank. Modern toilets are equipped with mechanisms of a rather complex design.

Apartment owners use (and dismantle, if necessary, repairs) both outdated models and technically advanced ones. The disassembly process can be carried out directly on site - without removing the tank or after dismantling the latter. Which option will be used depends on various factors.

Modern toilet cistern design. Such products are equipped with more advanced mechanisms for collecting and draining water. Non-ferrous metals and plastic are used here as materials for technical fittings. Uses a push-button control system

Typically, dismantling is carried out with the aim of completely replacing the tank along with the mechanism with a more advanced model. The storage tank must also be removed in case of water leakage at the connection points with the toilet. For example, due to wear of sealing gaskets, breakage of fastening bolts, and the appearance of microcracks in the housing. Let's look at how the toilet tank is removed in any of these situations.

The classic design involves fastening the toilet cistern with just two studs or bolts (d = 5-7 mm). Typically, metal (bronze, brass, steel) studs with double-sided threads for nuts are used as fasteners. Steel fasteners were used on older models. The service life of steel fasteners is relatively short. Sometimes such pins “burn out” from rust after a year of using the device.

Typically, flush tanks are fixed to the toilet body in the rear area. There is a specially protruding shelf for installing the tank. There are two holes on the surface of the shelf, which exactly coincide along the axes with the holes in the bottom of the tank. Most designs support two-point fastening

Fastening to the base of the toilet is usually done through two holes (or through 3) made in the bottom of the tank. The same two holes, in the same axes, are on the rear extension shelf of the device.

Fastening pins are passed through the aligned holes, gaskets are put on them on both sides and tightened with nuts. The cavities of the tank and toilet bowl are united by a common pipe, insulated at the junction with a rubber sealing ring.

Option for mounting the drive according to a three-point scheme. This solution is considered more reliable, as it provides better stability of the container. In addition, fastening the tank at three points contributes to a better fit of the sealing gasket. The risk of leakage in this place is reduced, which means you will have to disassemble the tank less often

The problem of how to remove the tank from the attached toilet shelf is solved as follows:

1. Close the centralized water supply valve.
2. Disconnect the water supply hose.
3. Empty the storage tank by pressing the drain button.
4. Unscrew the drain button head and remove the top cap of the reservoir.
5. Collect the remaining moisture inside the tank with a sponge.
6. Unscrew the nuts on the mounting studs (on the bolts) under the attached shelf.

Now all that remains is to carefully lift the tank, separating it from the installation site (possibly with some effort, because sometimes the gasket sticks) and then move it to the place where you plan to perform further work.

Bottom view of the toilet cistern after removing it from the attached shelf. In the center you can see a rubber sealing gasket covering the plastic nut securing the drain mechanism. On the sides there are two studs for fastening the drive. A little lower on the right you can see the threaded part for the hose of the water supply module and a plastic fastening nut

Modern models in the mid-price segment usually use a push-button mechanism for double water flush (3/6 liters). One press of any button switches on the operating mode of the drain and fill modules. You can come across a variety of versions of such mechanisms. However, the assembly configuration for them is the same:

• head with buttons and threaded part for the valve mechanism;
• valve mechanism with lower threaded part;
• sealing gasket;
• valve mechanism fastening nut.

When the top cover is removed, the head with the buttons will already be twisted. All that remains is to remove the sealing gasket from the fastening nut. The gasket (rubber ring) has a pentagon-shaped or circular inner area.

The fastening nut has the same shape along the outer border (not always). When assembled, the sealing rubber ring is placed on the nut. It is removed and the nut is unscrewed. The released mechanism can be easily removed. The filling system is attached using the same method.

Often, after prolonged and intensive use, the toilet flush mechanism becomes unusable. In order to find and fix the problem, you need to know how to disassemble a toilet tank with a button. Such a difficult task at first glance will be within the capabilities of every owner.

As practice shows, sooner or later any toilet is susceptible to leakage, regardless of its cost and design features. The source of trouble is often the drain tank.

Typically, the cause of a tank malfunction is the breakdown of some part of its design. Often the rubber diaphragm wears out and allows water to leak through. In this case, you will have to remove the siphon and replace it with a new membrane. To do this, you need to remove the drain tank and disconnect it from the water supply.

To fix a toilet malfunction, you will have to disassemble the flush cistern.

Sometimes leaks occur due to clogging of the diaphragm and the appearance of plaque on it. In such cases, you can do without replacing the part, but simply clean it. However, carefully inspect the membrane; the slightest crack can lead to a recurrence of the problem. A damaged gasket must be replaced.

Filling the container with water too quickly or too slowly indicates a possible misalignment of the float. To do this, you simply need to remove the cover and adjust this unit so that the gasket fits tightly and completely to the drain hole. To perform these steps you do not need special tools; everything can be easily done manually.

When the float rises to the desired level, the water supply to the tank must be stopped

In this case, it is important to determine the correct angle of the drain assembly by bending the float mounting fittings. By creating more space for the drain mechanism, you will ensure that water is drained when the tank is not completely filled, which will help save water costs.

As you can see, eliminating any malfunction in the drain tank will necessarily entail work on disassembling the tank. To find out, how to remove the tank from the toilet, you need to study its structure and understand the principle of its operation. Recommendations professional craftsmen And step-by-step instruction dismantling tools can also make your work much easier.

Design features and principle of operation

To avoid mistakes during repairs and damage to plumbing, before How to remove a toilet lid with a button, you should carefully study the principle of the flush cistern. Regardless of the cost of the model, the design of all products is approximately the same.

A toilet tank is a reservoir made of earthenware, polymers or metal, constantly filled with water and covered with a lid made of the same material. On compact models, the fluid is drained by pressing a button on it. Old-style products are equipped with a lever or a rising rod for these purposes.

Since toilets of the first type are especially popular today, we will consider the features of their design.

Drain tank design diagram

The internal system of the tank consists of constipation And drain node connection. Both of these blocks are interconnected. These usually include a rod for regulating the water supply, an overlapping membrane, a float indicating the liquid level in the tank, a siphon and their connecting parts.

Locking block performs the functions of filling the container and preventing it from leaking in standby mode. Water is drawn into the tank to a predetermined level and tightly clamps the membrane to the drain hole. If it is necessary to drain the fluid, pressing the button comes into effect drain mechanism, lifting the rubber diaphragm and thereby opening the access of water to the toilet bowl.

Usually, either the locking unit fails, and then liquid constantly leaks into the bowl or onto the floor, or the drain fittings, when the drain button does not work and when it is pressed, the tank remains full. In some cases, water does not enter the tank at all.

To determine the nature of the malfunction and eliminate it, before removing the lid from the toilet tank, you should find out the procedure for disassembling the tank.

Dismantling Guide

Of course, you can always contact a plumbing specialist who will quickly and efficiently carry out repairs. However, breakdowns of this kind are usually not very difficult, so it would be more advisable to fix the problem yourself. At the same time, you will not spend extra material resources and will acquire some plumbing skills.

Every owner has the tools necessary to carry out the work.

So, to figure out how to open the toilet tank lid, first of all, you need to stock up on the necessary tools for this. Typically their list looks like this:

• plumbing pipe wrench No. 1 or its Swedish adjustable equivalent;
• power lever on adjustable wrench; it may be required if the toilet has been in use for a long time and is being disassembled for the first time;
• pliers;
• screwdriver.

In addition, you should remember some nuances of removing the cover. Professionals recommend choosing a place convenient for work, where you can see all the fasteners and dismantle them without difficulty. It would be useful to know that you need to unscrew the nuts from the earthenware body especially carefully, avoiding their distortions, so as not to damage the fragile material.

Do not forget to turn off the water supply valve before opening the toilet tank with the button, otherwise you may accidentally cause a flood. If the valve is covered with rust and cannot be moved, in this case it would be appropriate to seek help from specialists. Trying to open it yourself, you can simply break off the tap, which threatens to flood your home.

After making sure that the water supply to the toilet is blocked, you should drain all the liquid from the tank. After these simple steps, you can proceed directly to dismantling the tank lid. Here it must be said that there are models with one or two buttons. The principle of operation in both cases is approximately the same, although there are still some differences.

Having drained the water from the tank, you can begin to dismantle it

The process of dismantling a product with one button on the lid

Before how to remove the lid from the toilet, you need to firmly grasp the ring surrounding the button and turn it. If the element is clamped tightly, you can use pliers, but do not forget to wrap the ring with a rag or just paper. This will help prevent scratches on it. As soon as you feel that the fastening has given way, continue the actions only manually.

You need to turn the part counterclockwise, otherwise you will tighten the fastener even more and risk completely stripping the threads from the base cylinder. The ring should be unscrewed very carefully so as not to damage the surface of the tank. After removing the part, which has a cylindrical shape, you can proceed directly to removing the cover.

You need to be very careful when unscrewing the ring that secures the button.

The design is attached to the button itself on a special clip with latches on both sides. First you need to slightly lift and rotate the lid perpendicular to the tank. This will help you access the clothespin. Carry out all actions smoothly and slowly, so as not to accidentally damage the fastening points inside the tank.

Next, having unfolded the part, you can grab the right latch with one hand and the left one with the other. Rotating the clothespin around its own axis, turn the knots in directions opposite to each other. A characteristic click will indicate that the fastener has been released and you can easily remove the cover.

Steps to take when removing the two-button cover

In order to remove the cover on a model with two buttons, you need to push one of them down. There is a small indentation on the inner surface of the second key. You need to pry the part behind this slot with a screwdriver or any other sharp object and remove the button body. In the same way, you need to remove the remaining key. You now have access to the spline where the cover is secured. The screw must be unscrewed carefully, being careful not to strip the thread.

Having pulled out both keys, unscrew the slotted screw that secures the cover

As with the one-button mechanism, the lid must be slightly lifted and carefully rotated until it is perpendicular to the toilet cistern. The latch that secures the lid is removed in the same way as in the first case, opening the clothespin in opposite directions while rotating it. Once clicked, the cover can be removed.

Nuances when disassembling the toilet cistern

Now that you know how to remove a toilet tank lid with a button, you can get started. However, during work it is still worth following some recommendations from specialists.

First of all, care must be taken during dismantling, especially when working with ceramic products. Any, even minor mechanical impact can lead to the appearance of a crack on the earthenware surface. Remember that it is impossible to purchase a cover separately from the tank, so if the product is damaged, you will be forced to replace the entire tank.

The method described above for removing the cover is suitable for models in which water supply connections are connected to the side. If water enters the tank in another way, carefully inspect the lid for additional fasteners. Most likely you will have to dismantle them.

Most models have a side water supply to the tank

The water drainage system also has its own characteristics in different models. Sometimes it simply unscrews, but there are products where the lid lifts up, and under it there is a screw that secures the drain mechanism.

To eliminate some breakdowns, removing the cover is not enough. If there is a need to disassemble the water supply valve to the tank, you need to free this unit. To do this, you need to unscrew the nuts holding it located on the water supply hose. In most models it is connected to the side wall of the case. You can carry out such actions using a pipe wrench and pliers.

Remove the drain assembly by carefully turning it counterclockwise. Remember that all parts of the tank are made of plastic, so you should not make significant efforts to dismantle them to avoid accidental damage. After unscrewing the block, remove it and remove the sealing gaskets that secure the mechanism to the tank.

To remove the tank completely, you need to unscrew the nut between it and the toilet bowl

The toilet tank performs a simple, but quite important function. It acts as a storage tank for collecting water.

The design of the drive itself is not too complicated. Often a breakdown occurs in this part of the toilet and in order to fix it, you need to dismantle it.

In this article you can find the answer to the question of how to disassemble a tank with a button in order to be able to fix a breakdown in this mechanism.

The drive with the button is mounted on two rods (studs) with a diameter of 5 to 7 mm. For fastening, metal studs (bronze, steel, brass) are used, with threads on both sides for nuts.

Such fasteners are typical for outdated models. It can last relatively little. It happens that such a part may rust a year after work.

The design of such a mechanism is mounted on the back of the plumbing body. For them, there are protruding surfaces on which there are two or three holes for the tank studs.

Rods are passed through them, after which special gaskets are put on and a screed is made. The cavities of the cistern and toilet bowl are connected by a pipe.

First of all, to remove the storage tank, you need to stop the water supply. After this, the hose through which it is supplied is removed and the storage tank is released (to do this, you need to press the drain button).

Next, the head of this button is turned away and the top cover is removed. After the remaining moisture inside the drive is collected with a sponge, you need to unscrew the nuts on the studs under the protruding shelf.

When all these steps are completed, you only need to carefully separate the drive from its installation location.

Removing the tank roof

On new models, the cover fasteners and other parts are made more skillfully than on older ones. These designs have a special fastening nut for the valve cover, which serves as one or a pair of buttons.

The method of removing the lid from the tank depends on how many buttons are on it. Single-button designs are easier to remove than those with two buttons.

The process of dismantling a product with one button

In order to dismantle the cover with one-button fastener, you must:

• Press the drain button;
• Next, you need to carefully turn the head of the push-button mechanism counterclockwise;
• By removing the plumbing key and completely unscrewing this head from the sleeve, you can remove the cover and begin repair work or replacement of the mechanism.

How to remove a toilet cistern lid with a double button

In addition to buttons that can be simply unscrewed without any effort, there are also mechanisms that are difficult to disassemble. A lock is installed on them. As a rule, they are inherent in two-button models.

On two-button tanks there may be various methods of fastening. Most often, for such drain designs, it is not enough just to unscrew the two-button head.

• A small button is pressed;
• after this the inner part of the wall with a narrow slot will appear;
• using this slot you need to press out the latch with a screwdriver;
• First you need to remove the large button;
• the second button is pulled out;
• Once the fixing screw is removed, the cover can be removed without any problems.

There may also be a design in which you first need to unscrew the decorative nickel-plated washer. Next, you will need to turn the drive cover so that it is across it. While it is in this position, the fixation brackets, which are located in the bowl of the two-button head, are pressed out.

After this, the cover will be finally released from its fastening and can be removed.

Disassembling the drain mechanism

Among popular and new models, the most common are two-button mechanisms for draining water. After pressing one of the buttons, either the drain or filling module is turned on.

There are many options for such mechanisms, but they are assembled according to one type. As a rule, they consist of a sealing gasket, a valve mechanism mounting nut and the two-button head itself.

The two-button mechanism will already be twisted when the drive cover is removed. All that remains is the removal of the rubber ring. It has an internal area (round or pentagonal).

It is necessary to remove the rubber ring and unscrew the nut. The released mechanism will be easy to remove.

As a rule, plastic is used to make old fittings. If it needs repairs, the mechanism is disassembled, but it will be easier to purchase a new one.

Removing an old toilet cistern

Those who have not yet replaced the old tank model with a more modern one have to repair the mechanism more often, since its parts have already worn out significantly.

However, in this case there are also positive aspects, because the owners of such structures do not encounter difficulties in removing the cistern or repairing it. The mechanism of older models of plumbing fixtures is quite simplified in comparison with new models.

To remove the cover, you just need to unscrew the handle and unscrew the washer nut made of plastic or metal. The float and drain mechanisms are located in the inside of the tank. They are attached to the bottom of the tank using two additional holes.

To remove the drive, you need to unscrew the two bolts in the bottom and carefully lift it away from its mounting location. An ellipsoid-shaped rubber ring isolates the water passage that goes from the tank to the bowl. It happens that in old mechanisms there are overflow tubes installed, which are secured to the bottom of the tank with a plastic nut.

To dismantle the lever-valve structure, it is necessary to unscrew two bolts on the drain mechanism link. To disassemble the module, which performs the function of collecting water, you simply need to unscrew one nut, which is located on the outside of the storage tank wall.

Before performing these steps, you must turn off the water supply. There are also models in which the levers for draining water are attached to the wall of the tank. On such structures, the cover of the structure is simply located on the surface of the drive, not secured in any way.

Disassembling the compact begins with the tank. First, the water supply is shut off and the drain is pressed until the container is completely empty. The water drain button is unscrewed, which are usually plastic and screwed together very easily, so no tools are needed for this process.

Use your fingers to press the rim, which protrudes above the tank lid. This is followed by a counterclockwise rotation until completely unscrewed. And now the tank cap is already in your hands.

The fittings for filling water are disconnected from the tank. The water supply to the tank can be side or bottom. To unscrew the hose you will need a regular wrench or an adjustable wrench.

By removing the flexible water supply hose, the fallen rubber gasket is selected. If it is not damaged when the nut is tightened early, it is stored with the hose. When reinstalling the compact, the gasket may need to be replaced.

While unscrewing the hose with one hand, hold it with the other hand. After disconnecting the flexible connection, there is a clamping nut that secures the drain fitting to the compact container.

The clamping nut unscrews more often and easily. When using the toilet for a long time, the nut may be difficult to remove, then an adjustable wrench is used.

Next comes the disconnection of the tank from the bowl. The tank itself is attached to the toilet with two bolts, which are unscrewed. Mounting bolts can be plastic or iron. Plastic bolts are easy to remove, but iron bolts can become rusty and almost impossible to unscrew.

If the iron bolts cannot be unscrewed, a hacksaw is used, with which the bolts are carefully sawed off in the space between the bowl and the tank itself. The main thing is not to damage the seating gasket between them.

The drain fittings are secured with a plastic nut at the bottom of the tank. When deciding to remove it, the fittings are held with the second hand when unscrewing.

Removing the toilet bowl

The success of the bowl removal process depends on the age of the toilet, the method of securing it in place and the type of sewer system. Neighbors are notified of demolition work to ensure that the sewer system remains inactive.

At the bottom of the bowl there are bolts securing it to the floor; they can be covered with plastic “hats”. They are unscrewed with a key.

Often, during initial installation, bowls are embedded in a concrete screed on the floor. If so, then the space around, the floor tiles and fill, is dismantled with your own hands using an impact drill or hammer. The surface is beaten carefully so that this process is not traumatic for the earthenware.

To avoid damaging the toilet lid, it is removed. The fastening nuts are located under the rear seat on the bowl.

Disconnecting the toilet from the sewer pipe

The next step is the most important. The drain drain must be disconnected from sewer pipe. Often, residual water may leak out of the sewer. It’s worth getting buckets and rags in advance.

The integrity of the drain on the bowl is carefully maintained. The joint between the toilet and the pipe must be thoroughly cleaned of sealant, mortar residues, seals and other foreign matter.

If the toilet is connected to the system through a drain or “corrugation”, then the connector is removed from the sewer pipe. The outlet is cleaned of remnants of “corrugation” and sealant.

It happens that the earthenware drain is directly connected to the system. In this case, the bowl is grabbed with both hands and slightly raised. It is examined how freely the earthenware moves in the sewer pipe. By slightly twisting and rocking, the outlet is pulled out.

It is worth noting that imported plumbing fixtures are somewhat more complex in design than domestic ones. Before dismantling the toilet, you should make sure that there are open fasteners and evaluate the method of installing the compact. If there is no confidence in the further preservation of the integrity of the system, then it is better to use the services of professional craftsmen.
