Toilet cistern: the device, the operating principle.

In order to understand the principle of work of toilet tank must be at least superficially familiar with his device.

device cistern

toilet cistern - a device that consists of a body, the trigger of the guide tube, locking device, pears and saddle.The housing is made mainly from a ceramic or plastic.Slightly less common tanks of metal.The trigger mechanism is in the form of buttons, and levers, which are located on top of the lid or in the side.Drain fitting for the toilet tank depends on the price of the goods and country of origin.

operating principle of the toilet tank

tank is in effect by pressing the trigger.This mechanism cistern, in turn, linked to its internal structure.

before pressing the device is in standby mode.It has water, which is automatically filled to a certain level.All liquid holding pear cistern, which is on its bottom.It is made of rubber, so tight to the seat.

When a person presses the button or pulls the handle is actuated traction.It, in turn, acts on the bulb, and it starts to rise.As a result, the seat will not overlap, water gets into the hole and drained the tank into the toilet bowl.

Once the button is released or the toilet cistern handle pear does not return to the same moment in the starting position.This would drain short.The principle of slow descent pear is its device.Inside it is completely empty, and there is only air, which pushes it upwards.As you fill the tank with water lift pears decreases.As a result, it is completely pressed against the saddle.Without the guide tube such action would be impossible.The fact is that the bulb affects a lot of forces that drive it towards the least resistance.If she was not connected with the guide tube, she would never return back to the center, to the saddle.

Adjust the water level

Adjusting the water occurs by means of a locking device in the tank.According to the principle of action distinguish piston and diaphragm device.The most common in our time is the second.Largely selection lies in the simplicity and reliability.The disadvantages of such arrangements include their frequent blockage.This happens because of the fine particles contained in the water and get through a flexible liner in the toilet cistern.Filtration device is fully capable to solve this problem.

disassemble the tank?

to repair the cistern, to begin to understand the reason for his failure.For this primarily need to look at its internal structure.To get to it, simply remove the top cover.For convenience, in many cases it is not mounted on the reservoir.To remove it, simply lift it over.You have to be careful because the toilet tank lid is not very easy.If you have a handle on it, it will interfere with removal.In this situation, you must do it first, and only then remove the cover.It is generally on the thread guide tube reservoir.To remove the handle, it is enough to lift it a little bit up and to take up the handset.When the tube is fixed in one hand, unscrew the second handle (rotate on an axis counterclockwise).Make it a lot easier to fix if the guide tube with pliers.After that, the handle may be safely removed as her are not lining and any other details that are associated with it.

Job modern tanks

Modern manufacturers in recent times began to produce flushing cisterns, in which the tube passes through the bulb on its axis.For added convenience, there is a float which has a special latch.This mechanism works much more efficiently.When you trigger a pear rises, as in the classical model.Further, it does not fall into the water and remains in the upper part.Ensured thanks to the latch that held up the float.When the water in the tank is completely finished, the latch releases the float, and the blower will return to its original position.

Check tank design

Before you start, you must get rid of all the water in the tank so that you can see the entire structure.You can do this in two ways.The first is the ceiling in the toilet water supply and drain water.The second method is to fix the pear in the upper position.This hole will always be open, and the water will be able to freely leave the container.In order to do this, you must take the float, which is associated with a blower.Next, it is necessary to fix the upper position at a side of a tank.For this purpose, perfect metal twig.If there is none, you can use a screwdriver and place it properly.

The first step is to inspect the toilet cistern.The device should be clean and free of dirt.If there is none, you need to turn your attention to the float.Ideally it should be in water no more than half.Water should not be above the level of the drain tube.After checking the level necessary to begin the study of the drainage mechanism.

Types pears and especially

Pears in the cistern there are two varieties.The first type - a pear-float.On top of it there is a special hole that is connected to the rod.This occurs by means of the internal thread hole which is in pears.The second type - a pear-valve.Like the first, it has a hole at the top in the middle.However, it is the difference between what it through.Inside the hole is also mounting for the rod.When the connection is faulty, water is seeping through the pear and into the tank opening.

In order to fully explore it, you need to extract, while disconnected from the flush mechanism.Pear-float just unscrew it, if stock is fixed.To remove it, you must turn the valve toilet cistern, which is located under the trigger.

form pears to be no obvious defects.If visible cracks and fissures, it can not be operated on.

buying a new pear should be given special attention.If the size is greater than the former, it can not reliably block the hole.As a result, it will have to change or manually grind sand column.

After installing the new pears need to follow its work.There are times when the water continues to trickle even after replacement.This may be due to the fact that the edges are not fully taken pear shape of a saddle.After a couple of hours of active operation of the reservoir it must be finally stand in place and take the desired shape.

Installing cistern

Installation takes place in five phases.The first is to collect all the elements.Drain fitting for the toilet tank must be folded according to the instructions.The second step is fixing the tank to the toilet bowl.For this purpose, special screws.The third step is to connect the tank to the drain plumbing.All joints drain should be securely connected.The fourth step is controlled float inside the tank.For this, he is exposed to the desired level to which water will be recruited.Finally, the fifth stage of the trial is to start after the completion of all works.If no leaks, and water is taken in the toilet cistern, then everything is working properly.

Causes damage cisterns

To eliminate leakage at home, not necessarily invite plumbing.Prices for its services will hit the pocket, and in fact need only become familiar with the general principle of the work to prepare the necessary tools on the market and buy the necessary details.The main thing - to understand the mechanism of tank eventually wear out and will always require repairs or complete replacement.Damage often accompanied by leakage of water.In some situations, the water can flow into a toilet bowl, in others - be unexpectedly on the floor in the toilet.This kind of failure is extremely dangerous and requires rapid intervention.Otherwise, the water gets to the neighbors, and the problems will be even greater.However, the failure of the internal mechanism of the toilet tank leaks are not always followed.Sometimes the tank is simply not taking on water.Buying very expensive toilet on the market will not solve the problem because they have the same design.Unlike in most cases it consists only in some detail.Inside flushing cisterns are arranged exactly the same way.Also, the problem of damage to the tank may be to trigger.It often happens that he starts to jam and then we can not normally be used.This is largely dependent on its type.Given the nature of the trigger should be on the market to purchase a new key or lever of the toilet cistern.

Dirt in the tank

second most common cause of failure of toilet tank (after the failure of pears) is the accumulated dirt in it.Since the toilet cistern - a device that is directly connected to the water supply system at home, get out all the impurities in it.As in most cases in the water is not very clean water, it contains a lot of particles that clog the tube.This may be rust or other small particles.When they enter into the tank, some of them washed off the toilet during its use.Another part of the dirt deposited on the bottom of the tank.When it sticks to the saddle, it prevents pear completely close the hole.As a result, the water is not completely overlapped and gradually begins to occur.

Under the cover of a tank can always notice a large amount of rust.Pollution in moderate amounts do not need to be cleaned.However, if the layer is large, it is necessary to remove it from the surface.This does not necessarily use the cleaners, just wipe with a cloth all.

Repair locking device

Problems with the locking mechanism can be solved without plumbing.Prices of new parts for the toilet cistern is not too high (pear, for example, costs 15-20 rubles, rod - from 300 to 800 rubles).Problems of the locking mechanism can be seen on the float, which is in the cistern.When it is completely submerged in water, it indicates the presence of liquid in it.This occurs due to the fact that it is connected to the lever.When the water is filled, it hits the arm and begins to flow through it.If the float is not sufficiently tightly planted, the water gets inside.In order to get rid of the water float must be removed, scroll through it with lock lever.Next, the liquid should go smoothly.If not, you need to suck it.To do this, you need to prepare pear and straw.Last one end fits over the bulb and the other end sticks to the float.When you click on it the water is sucked.To avoid further problems with the float, you need at the end of the lever to put the damper.You can use any suitable size plastic cap.
