Modern plumbing is very fault-tolerant, but sometimes its maintainability leaves much to be desired. Even experienced plumbers sometimes stop at a loss, not knowing how to remove the lid from the toilet bowl or adjust the filler valve.

The main points of repair of the now widely distributed kits we will consider in this article.

Dismounting the lid

Option 1

Let's start with the simplest scenario.

How to open the lid of the toilet bowl, if it is a domestic set of fixtures with a rod that rises with the help of a plastic handle?

1. We unscrew the plastic handle, holding the rod.
2. We unscrew the brass or plastic hollow screw screwed into the guide rod of the tube.
3. Remove the plastic washer under the screw. The cover is free.

Option 2

In most import kits, the lid is held by the drain button. More precisely, its rim.

The procedure is as follows:

1. With dry fingers, take hold of the rim and rotate it counter-clockwise.

Pay attention: in order to build a nut, it sometimes takes quite a serious effort.
  To prevent fingers from slipping, rubber gloves can be used. But to use the gas key is only in the extreme case: the appearance of the rim will be irreparably damaged.

1. After loosening the nut, unscrew it completely.
2. Pull the drain button up, pull it out and remove the lid.

Option 3

How to remove the lid of the toilet bowl, if the rim does not turn when applying a significant effort?

1. Armed with a thin screwdriver, we catch the edge of the push-button part of the drain button and carefully remove it.
2. Under it is found a nut that can be turned with fingers, tweezers or round pliers. Turn it counterclockwise, then remove the drain button. The cover is free.

Option 4

In some tank designs, the drain button is screwed to the cover with a nut located on the rear side. The button is a lever mechanism, which when pulled pulls the chain and raises the plum pear. A characteristic feature of the design: when you try to remove the lid, water begins to merge into the toilet.

The lid for the toilet tank of this type is removed as follows:

1. Close the water on the tank.
2. Raise the cover so that it can be pushed through the fingers, and unhook the hook of the lever from the chain.
3. Remove the cover.

Note: again cling the button will be quite inconvenient. A little help with the task of a long tweezers. When dismantling the cover, remember which chain link was hooked: this saves you time, which otherwise will have to be spent on adjusting the drainage mechanism.

Replacing the drainage mechanism

Option 1

If you have a new tank with imported fittings, replacing the drainage mechanism is simple to indecency. It is a one-piece structure, which does not require the removal of the tank for replacement.

The outlet, saddle and cuff between the reservoir and the shelf will remain old: kits of this type are compatible with each other.

1. Close the water on the tank.
2. Remove the drain button and cover.
3. Turn the drainage mechanism clockwise a few degrees and pull it upwards.
4. Clean the outlet and the seat to which the gasket is pressed against deposits and small debris.
5. Install the new drainage mechanism and turn it anti-clockwise.
6. Turn on the water supply and make sure that the mechanism completely covers the drain in the closed state.

By the way, the situation when it is necessary to completely replace the node is a rarity. In most cases, the problem with water leakage is solved by cleaning the seat or replacing the ring gasket. The operation takes no more than a minute and does not require any special skills.

Option 2

For domestic sets with a separate shelf, replacing the plum mechanism is much more difficult.

No, all operations are intuitive; but the amount of work to complete the replacement of the node will take much longer.

1. We cover the water on the tank.
2. The lid for the toilet bowl is dismantled after the nut under the drain handle is unscrewed.
3. Then we disconnect from the filling valve flexible liner.
4. We unscrew the bolts holding the shelf and, often, the seat with the lid. Polyethylene bolts with nuts are easily turned away by hand; if a brass or galvanized bolt was used to install the kit, you will need to use pliers and a wrench. Steel bolts without anti-corrosion protection and do have to saw with a saw blade.
5. Having fed a tank back, we pull out release of a shelf from a conical cuff. Be ready to replace this cuff: the rubber will lose its elasticity over time, and the connection after the assembly can flow.
6. We put the construction on a flat surface and consistently untwist all the bolts. Of course, avoiding distortions, strictly in pairs. Steel bolts, if any kind soul has made them happy with the owner of the toilet bowl when assembling, will have to be cut.
7. After separating the shelf and removing the drain mechanism, carefully remove all debris and deposits around the holes.

1. We mount a new mechanism, not forgetting to install a gasket under the brass saddle. As for the bolts, the rules already known to us apply: they are tightened in pairs, one at a time - two turns at a time and without excessive efforts.
2. We fix the shelf. Oval gasket under it is better to replace: it certainly ceased to be elastic. As a last resort, he will help out the damage inflicted on both sides.
3. We check the design for leaks: stop the release of the shelf with a cloth and fill the tank with the pear lifted with water.
4. If not, check the tightness of the sink: fill the tank already with the pear down.
5. If everything is in order, you can install the tank in place. The conical cuff is stretched to release the shelf and rolled up to it with a wide bell. After the bolts securing the shelves are twisted, roll the cuff to the socket of the toilet bowl.
6. We connect flexible piping and turn on water.
7. After all equipment has passed the operational test, the lid of the toilet bowl is installed and fixed with a nut.

Replacement and adjustment of the priming valve

The replacement is reduced to untwisting the nut fixing the old valve, and twisting a similar nut from the new valve. Of course, there must be a rubber gasket on the inside of the tank, which ensures tightness.

With the installation of the filling valve, however, a couple of nuances are connected.

• Reinforcement with bottom piping is often completed with a plastic fine filter, which must be placed between the fill valve and the hose. Throw it out immediately: it will be constantly clogged with the smallest sand that is safe for the operation of the valve. Where is the filter more effective? coarse cleaning  at the entrance to the apartment.
• Flexible connection is connected without tension and bends with a small radius. The load on the union will significantly reduce the already short life of the hose.

Attention: do not use excessive force when tightening the union nut. They are not only not needed for soft padding; The excess force is also capable of cutting the thread on the valve.

How to adjust valve response level in modern kits?

There are two options.

1. The float can move with some effort on a plastic strip with ledges. To raise or lower it, it is enough to move the rail to a wider part of the hole in the slot of the float.

1. No less common screw adjustment. The float is adjusted by turning (using a screwdriver or manually) a long plastic screw.

Conclusion

Unfortunately, the abundance of all kinds of constructive solutions does not allow us to describe in detail all the constructions of the reinforcement. As usual, the video in this article will show more vivid information.

Often after a long and intensive operation, the toilet flush mechanism becomes unusable. In order to find and fix the problem, you need to know how to disassemble the toilet bowl with the button. Such a difficult task at first glance, it will be quite possible for each owner.

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

Usually the cause of the failure of the tank is the breakdown of any part of its design. Often, the rubber diaphragm wears out and lets in water. In this case, you have to remove the siphon and replace it with a new membrane. To do this, remove the drain tank and disconnect it from the water supply.

To fix the toilet bowl it is necessary to disassemble cistern

Sometimes leaks occur due to fouling of the diaphragm and the occurrence of a plaque on it. In such cases, you can do without replacement parts, and just clean it. However, carefully inspect the membrane, the smallest gap can lead to a repetition of the problem. Damaged gasket must be replaced.

Too fast or slow filling the tank with water indicates a possible skewing of the float. To do this, simply remove the cover and adjust this assembly so that the gasket fits snugly and completely against the drain hole. To perform these actions you do not need special tools, everything can be done manually.

When lifting the float 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 armature of the float attachment. By creating more space for the drainage mechanism, you will ensure that the water is drained when the reservoir is not fully filled, which will save water costs.

As you can see, eliminating any malfunction in the drain tank necessarily entails work on the disassembly of the tank. To find out, how to remove the tank from the toilet, you need to study its device and understand the principle of its operation. Recommendations of professional masters and step-by-step instruction  on dismantling are also able to greatly facilitate your work.

Features of the design and principle of operation

To avoid mistakes during repairs and spoiling of sanitary ware, before how to remove the lid of the toilet bowl with the button, you should carefully study the principle of the device of the drain tank. Regardless of the cost of the model, the design of all products is approximately the same.

The toilet bowl is a tank of faience, polymers or metal, constantly filled with water and covered with a lid of the same material. On the "compact" models, the liquid is drained by pressing a button on it. Products of the old model are equipped with a lever or a rising stem for these purposes.

Since today the toilet types of the first type are especially popular, let us consider the peculiarities of their device.

The scheme of the device of the drain tank

The internal system of the reservoir consists of shutoff  and drainage junction. Both these blocks are interconnected. They include a rod for regulating the water supply, overlapping the membrane, a float indicating the level of liquid in the tank, a siphon and connecting parts.

Locking unit  performs functions to fill the capacity and prevent its seepage in the standby mode. Water is recruited into the tank to a predetermined level and tightly clamps the membrane to the drain hole. If necessary, drain the fluid while pressing the button comes into effect drainage mechanism, raising the rubber diaphragm and thus opening the water to the bowl of the toilet.

Normally, either the locking unit breaks down, and then the liquid constantly flows into the bowl or floor, or drainage, when the drain button does not work and when it is pressed, the tank remains full. In some cases, water does not enter the reservoir at all.

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

Disassembly manual

Of course, you can always turn to a plumber, who will quickly and accurately repair. However, breakages of this kind usually do not pose a great deal of complexity, therefore it will be more expedient to solve the malfunction yourself. At the same time, you will not spend extra material and acquire some skills in plumbing.

The tools necessary to carry out the work are found by every owner

So, to find out how to open the lid of the toilet bowl, first of all, you need to stock up with the necessary tools for this. Usually their list looks like this:

• sanitary pipe key number 1 or its Swedish adjustable analog;
• lever-amplifier on the adjustable wrench; it may be required if the toilet has been in operation for a long time and is being disassembled for the first time;
• pliers;
• screwdriver.

In addition, you should remember some of the nuances of removing the lid. Professionals recommend choosing a convenient place to work, where you could see all the fastenings and dismantle them without difficulty. It would be superfluous to know that it is necessary to unscrew the nuts from the earthenware case very carefully, avoiding their skewing so as not to damage the fragile material.

Do not forget before you open the toilet bowl with the button, close the water supply valve, otherwise you can accidentally arrange a flood. If the valve is rusted and does not lend itself, in this case it will be appropriate to seek the help of specialists. Trying to open it yourself, you can simply cut off the tap, which threatens to flood the housing.

After making sure that water access to the toilet is blocked, you should drain all the liquid from the tank. After these simple actions it will be possible to proceed directly to dismantling the lid of the tank. Here it is necessary to say that there are models with one or two buttons. The principle of work in both cases is approximately the same, although, nevertheless, it has some differences.

Drain the water from the tank, you can start to dismantle it

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

Before how to remove the lid from the toilet, you need to firmly take hold of the button ring and turn it around. If the element is tightly clamped, you can use the pliers, but do not forget to wrap the ring with rags or just paper. This will help avoid scratches on it. As soon as you feel that the attachment has yielded, proceed only by hand.

Scroll the piece in an anti-clockwise direction, otherwise you will tighten the fastener even more than risking completely tearing the thread from the base cylinder. Unscrew the ring 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 the removal of the lid.

Unscrew the locking button ring carefully

The design is fixed to the button itself on a special clip with snaps on both sides. To start, you need to slightly raise and turn the lid perpendicular to the tank. This will help you gain access to the clothespin. Do everything smoothly and slowly so as not to spoil the fastening points inside the tank.

Further, having developed a detail, it is possible to undertake one hand for the right latch, and another - for the left. Rotating the clothespin around its own axis, unfold the nodes in opposite sides to each other. A characteristic click will say that the mount is released, and you can remove the cover unhindered.

Actions when removing the cover with two buttons

In order to remove the cover on the model with two buttons, you need to drown one of them. On the inner surface of the second key there is a small depression. It is necessary to poke the part behind this slot with a screwdriver or any other sharp object and remove the button case. In the same way, you need to get the remaining key. Now you have access to the spline mount, where the lid is fixed. The screw must be carefully, trying not to break the thread, unscrew it.

After removing both keys, unscrew the locking cover of the slotted screw

As with the one-button mechanism, the lid should be slightly raised and gently rotated until it assumes a perpendicular position relative to the toilet bowl. 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. After clicking, the cover can be removed.

Nuances when disassembling the toilet bowl

Now, when you know how to remove the lid of the toilet bowl with a button, you can proceed to the action. However, while working, it is still worthwhile to follow certain recommendations of specialists.

First of all, during the dismantling, you must be careful, especially when working with ceramic products. Any, even insignificant mechanical impact, can lead to the appearance of a crack on the faience surface. Remember that you can not buy a lid separately from the tank, so in case of damage to the product you will have to replace the tank completely.

The above described method of removing the cover is suitable for models in which the water lines are brought from 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 lateral water supply to the tank

The water drain system, too, has its own characteristics in different models. Sometimes it just gets twisted, but there are products where the lid rises, and under it there is a screw securing the drainage mechanism.

To eliminate some breakdowns, removing the cover is not enough. If there is a need to disassemble the water supply valve in the tank, it is necessary to release this unit. To do this, unscrew the nuts holding it, located on the water supply hose. In most models it is connected to the side wall of the case. Such actions can be carried out with the help of a pipe wrench and pliers.

The drain assembly is removed by gently scrolling it counterclockwise. Remember that all the parts of the tank are made of plastic, so do not make significant efforts to dismantle them to avoid accidental damage. After unscrewing the unit, remove it and remove the gaskets that secure the mechanism to the tank.

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

If necessary, remove the tank completely, you need to unscrew the nut that connects it to the toilet body and remove the rubber sealing insert.

All dismantling work is quite easy and will not take much time. However, the masters recommend that you accurately remember the sequence of actions during the disassembly, and if possible, record it. Because to assemble a structure is always much more difficult than to dismantle.

Having found out a malfunction of a drain tank, it is not necessary to address at once to experts. Knowing his device, and also having free time and desire, you can always try to cope on your own. This will save you money to pay for the work of the master and gain skills in plumbing.

Most models have a lateral water supply to the tank To remove the tank completely, you need to unscrew the nut between it and the toilet bowl. To solve the toilet bowl, you have to disassemble the drain tank. When lifting the float to the desired level, the water supply to the tank should be discontinued. performance of works, there are at each owner Drain water from a tank, it is possible to start its dismantling. To unscrew a fixing button a ring it is necessary extremely accurately Having pulled out both keys, otk rivet locking lid slotted screw. There are wrenches or pull-out buttons.

Open the lid of the toilet bowl equipped with a button

When does it become necessary to open the lid of the toilet bowl?

Problems with the toilet - an unpleasant thing, it affects the amount of water consumed, the payment increases. But it is not always possible to call plumbing, you have to try to correct yourself. Most often in case of a fault in the toilet, the drain valve of the overflow tank breaks. Eliminate the failure only if you open the lid. Usually the toilet device has a similar design, but some modifications differ from the others.

In the toilet bowls of the last models on the top plane, there is usually one solid or one composite button that prevents the lid from being lifted easily.

And it can be difficult to understand how to open the lid.

In old models, it's easy to deal with this, it's enough simply to lift the lid up or unscrew the trigger of the trigger first. In modern, usually on the upper plane there is one solid or one component, of two or three parts, a button and a button glass, which prevents a simple lifting of the lid.

The toilet bowl with a button is often considered an undiluted structure, most plumbers try to convince us of this. In fact, it is quite easy to open and solve some small problems associated with the unstable operation of the mechanism.

Step-by-step instruction

The scheme of the device of a toilet bowl with a tank with the button. Tanks with buttons are often considered non-separable, but in reality this is not so.

List of tools:

• screwdriver slotted (flat),
• any other metal object with a flat end.

Step-by-step instruction for the tanks of the "IDO" system:

• using a screwdriver, carefully, so as not to damage the surface, turn the ring around the button counter-clockwise.
• after the shift, the ring can be unscrewed by hand, so it will easily rotate.
• unscrew the ring, it will look like a plastic cylinder.
• get it out.
• can .

Using a screwdriver, carefully, so as not to damage the surface, pry and turn the ring under the button counter-clockwise.

Step-by-step instruction for tanks with double buttons:

• press lightly on one of the halves of the button and find on the inner side of the other button a small slit.
• using a screwdriver, grabbing for the slot, pull out the half button.
• then remove the second half of the button.
• the slotted screw is visible in the hole formed, it must be unscrewed.
• it was possible to slightly lift the lid of the toilet. Gently rotate it 90 degrees until it occupies the position across the tank and it is not possible to remove the two-pronged clothespin holding the button: move one end to the right and the other end to the left, thereby rotating the clothespin along the central axis.
• you can remove the top of the toilet bowl.
• after removing the cover, place it on a flat, stable surface so that it does not break.
• after repair and elimination of all malfunctions, check operation in an open condition.
• further, after you are convinced of the correct operation of the mechanism, assemble the toilet bowl in the reverse order.

When carrying out any repair work related to plumbing, you should be careful and remember the safety rules. All components of the mechanisms that will be removed during the repair should be carefully placed on a stable, flat, horizontal surface and prevent children and pets from accessing them, as this may entail the swallowing of small objects.

The toilet bowl is a storage tank, where a set of water is carried out, in order to wash off the feces from the bowl of the ship to the sewage system at the right time. The tank itself has a simple structure. When people are interested in how to disassemble the toilet bowl, their interest often concerns the disassembly of the mechanism that is inside, or the dismantling of the tank, as a separate element of the whole structure.

The system for monitoring the set and water level is in each toilet bowl. Modern toilets are equipped with mechanisms of rather complex construction.

Owners of apartments operate (and dismantle if necessary repair) as obsolete models, and technically perfect. The dismantling process can be performed directly on site - without removing the tank or after dismantling the tank. Which option will be applied depends on various factors.

The toilet bowl is a modern design. Such products are endowed with more sophisticated mechanisms for recruiting and draining water. As materials under the elements of the technical reinforcement, non-ferrous metals and plastics are used here. The button control system is used

Usually dismantling is performed in order to completely replace the tank with the mechanism on the model more advanced. The drive must also be removed in the event of a water leak at the connection points with the toilet. For example, due to wear of gaskets, breakage of fastening bolts, the appearance of microcracks in the body. Consider how the toilet bowl is removed in any of these situations.

Removing the water tank on the toilet

The classic design provides fastening of the toilet bowl with only two studs or bolts (d = 5-7 mm). Usually, fasteners are metal (bronze, brass, steel) studs with bilateral threads for nuts. Steel fasteners were used on obsolete models. The service life of steel fasteners is relatively small. Sometimes such pins "burn" from rust after one year of operation of the device.

Usually, the downcomers on the toilet bowl are fixed in the back area. For the installation of the reservoir, a specially designed shelf is designed. On the surface of the shelf there are two holes, which exactly coincide along the axes with holes in the bottom of the tank. Most designs support fasteners in two points

Mounting to the bottom 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 side of the device.

Through the jointed holes, the fixing studs are passed, the gaskets are put on both sides and the nuts are tightened. The cavities of the tank and the toilet bowl are united by a common branch pipe, insulated at the point of joining with a rubber sealing ring.

The option of mounting the drive in a three-point scheme. This solution is considered more reliable, as it provides better stability of capacity. In addition, the attachment of the tank at three points contributes to a better fit of the gasket. The risk of leakage in this place decreases, which means that the tank will have to be disassembled less often

The problem, how to remove the tank from the toilet bowl, is solved as follows:

1. Close the central water supply valve.
2. Disconnect the water supply hose.
3. Release the drive by pressing the drain button.
4. Unscrew the head of the drain button and remove the top cover of the tank.
5. Collect the rest of the moisture inside the tank with the help of a sponge.
6. Unscrew the nuts on the fastening bolts (bolted) under the extension shelf.

Now it will remain to carefully lift the tank, separating it from the installation site (perhaps with some effort, since sometimes the gasket boils) and then move to the place where it is planned to perform further work.

A view from the bottom of the toilet tank after it has been dismantled from the front shelf. In the center there is a rubber sealing gasket covering the plastic nut of the fastening mechanism. There are two mounting studs on each side. Slightly below the right is the threaded part under the hose of the water set module and the plastic fixing nut

Dismantling the drain mechanism

On modern models of the middle price segment, as a rule, a button mechanism is used for double draining of water (3/6 liters). One pressing of any of the buttons switches on the mode of operation of the drain and filling modules. You can come across a variety of options for implementing such mechanisms. However, the assembly configuration for them is the same:

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

When the top cover is removed, the head with the buttons is already twisted. It will be necessary to remove the gasket from the fixing nut. The gasket (rubber ring) has an internal area in the form of a pentagon or round.

The fixing nut (not always) has the same shape along the outer edge. In the assembled condition, the sealing rubber ring is put on the nut. It is removed and the nut is turned away. The released mechanism is easily removed. The same method is attached to the filling system.

The scheme of most of the drain mechanisms of foreign and domestic production. The design of one-button control, which can be found on almost all the toilet bowls of budget execution.

The material of the reinforcement is plastic. If necessary, the mechanism is dismantled, but it's easier to buy a new one.

How to remove the lid of the tank

Again, returning to the models of modern toilet bowls, it should be noted that users often have a problem - how are the covers removed on such models?

Indeed, these designs are somewhat different from outdated toilets in the sense that they are made more technically, including the lid fastening. But in general, the principle remained old - the lid is pressed with the nut, which is included in the valve mechanism.

Technology showing how to disassemble a modern toilet flush tank, starting with the removal of the lid. The main task is to carefully unscrew and separate the button head. After this operation, the cover is removed and the repair action (replacement) of the drainage mechanism

On new models, as a clamping nut, there are heads with buttons, dnevnopochnye and two-buttoned. To remove a one-button fastener and remove the cover, the following steps are taken:

1. The button is pressed as if draining the water and held in this position.
2. Gently turn the head with the button counter-clockwise.
3. Finally, the head is turned out with the button from the valve mechanism bushing.

On different models, the threaded connection may be different. There is a wide-angle outer sleeve thread, as in the picture below and also there is an inner sleeve thread for a small diameter rod.

So it looks like the dismounted head of a single control button. This is only one of the possible configurations. In practice, there are different constructions  push-button heads. This point needs to be taken into account starting the disassembly of the toilet bowl

Along with single control buttons, whose head is simply twisted, there are more complicated constructions for dismantling, made with locks. Often such a solution has two-button mechanisms.

How to disassemble a tank with two buttons

On the toilet bowls, where a drain mechanism with two buttons is installed, there are different methods of fastening. With this configuration, simply turn the head and buttons off sometimes. In such situations, disassembly technology is as follows:

1. It is necessary to press into the body of the head only one of the buttons (small).
2. On the opened inner wall in the lower part will open a small groove.
3. Carefully press the screw through the groove with a screwdriver.
4. Remove one button (large) from the housing and then another in the same way.
5. Unscrew the fixing screw, which is located under the buttons.

After these operations, the lid of the tank with two buttons is removed without any difficulties.

The process of dismantling the head with two control buttons starts with pressing a small button. This opens access to the mounting opening on the side of the head housing. Through this opening, a small screwdriver is released from the screwdriver, after which the buttons can be removed and reached the fixing screw

Still come across the design of the tanks, where first you need to unscrew the decorative nickel washer, then turn the cover 90 degrees - that is, install it across the container. In this position, press the fixing clips located inside the bowl of the button head. After these manipulations, the lid is completely released from the fasteners.

Remove the toilet bowl of the old construction

Still continue to exploit a number of outdated models of toilets. It is more often necessary to repair the types of products that have worn out because of the considerable wear and tear of their components. But the owners of such structures do not have to think much about how to fix or remove the toilet bowl, due to the simplest design.

Type of mechanism inside the drain tank of an outdated toilet. Float control system set and pull control draining. The tank is also attached from below on two bolts. The top cover is removed easier and faster than on new models

So, to dismantle the same cover, just twist the handle on the stem of the drainage mechanism and turn the plastic (or metal) washer nut. Under the lid inside the tank is installed float mechanism  set of water and lever-valve draining 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 a similar manner to how it is applied to new models. It is necessary to unscrew two bolted connections in the bottom of the tank. The passage zone for water from the accumulator to the bowl on the old toilet bowls is insulated with an ellipsoidal sealing ring. Often in older systems, there are overflow tubes attached to the bottom of the tank with a plastic nut.

Some models of drain tanks are equipped with fastening screws with screwdriver heads. But to disconnect such fastening is recommended traditionally by turning the nuts from the bottom. So gaskets are not deformed. The screwdriver is used only to lock the screw from turning

To dismantle the lever-valve drain mechanism, it will be necessary to untwist two more bolted connections, which secure the rocker arm. Dismantling the water reclamation module is done by turning off just one nut from the outside of the tank casing.

Beforehand, disconnect the water supply hose from the storage valve. It should be noted: there are models of tanks with levers of water draining, embedded in the side wall. On such devices, the lid of the toilet is not fixed at all - it simply lies, leaning on the walls of the body.

Faults causing the tank to disassemble

Typical malfunctions that lead to disassembly are often:

• leakage at the time of draining in the area of ​​the gasket at the connection of the tank to the bowl of the toilet bowl;
• leakage in places of fastening of the store to the toilet shelf;
• violation of the functions of the drain mechanism;
• violation of the functions of the mechanism of water harvesting.

Often problems with leaks are eliminated by a simple tightening of the nuts of the fastening. The functionality of the drainage and reclamation mechanisms may be impaired due to insufficient water pressure in the centralized system. Therefore, before starting to disassemble, you should make sure that there are no other possibilities for eliminating defects.

Defects of functional fittings

If there is an involuntary leakage of water from the storage tank into the toilet bowl, it is likely that the locking ring is defective. It needs to be replaced. The same effect can be observed when the mechanism of the closing mechanism does not work. A possible cause is a seizing of the control button.

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

Care of plumbing

While engaging in disassembly of plumbing fixtures, each user should be mindful of the principles of ceramics care. To repair work it has the most direct relation.

Ceramic products are resistant to the effects of chemicals, but are easily damaged by cleaning with a metal mesh, abrasives and other similar substances. Cleaning of household plumbing after repairs should be carried out with soft substances and materials.

A few practical tips will help you cope with self-adjusting valves.

Instruction before the execution of works related to the repair of household appliances with their own hands is voluntary. However, extra information never hurts in any endeavors. The more information there is about a particular object, the easier and easier it is to perform all the actions. Disassembling modern toilets, in spite of the simplicity of actions, also does not exclude the reference to instructions.
