If you hear a rhythmic digging when the faucet is closed, then, most likely, there is a problem in which you will have to learn how to change the gasket in the tap.
This leaky gasket is often the cause of leaking from the tap.
Most often, gaskets with hot water in the kitchen break down( in the bathroom, cranes are used much less).
Replacement is a simple job that you can really do with your own hands.
After watching the video and reading our step-by-step instructions, you'll see for yourself.
Preparatory stage
If you do not plan to build a swimming pool in the building, first of all close the water supply valve to the apartment, and for the private house, perform a sequence of actions, as a result of which the pumping station will not supply water.
If the valve is missing or not working, then, of course, you will need to call the plumbing. In the pipe between the valve and the tap there will be some more water.
Opening the tap, you can only release a part of it into the sink.
Some volume( this depends on the height of the water pipe, the length of the flexible hose and the water pressure in the system) will remain in the pipe and it can be a very unpleasant surprise if you have to not only change the gasket, but also do additional work.
Therefore, it is highly recommended to estimate the volume of water left in the pipes after the supply is cut off.
An approximate estimate is required, so we simplify the calculation formula and take it as the square of the diameter of the water supply pipe in meters multiplied by the distance in meters from the shut-off valve to the tap and multiplied by 3.
If half a bucket of water can remain in the apartment in a pipe with a closed valveprivate house, this figure may well be half the volume of the bathroom.
As mentioned above, a significant part of this water will go away after the opening of the crane, but to evacuate the rest, prepare a bucket or a deep saucepan.
Prepare a certain amount of rags, this will make the work almost dry, not allowing the flow of water for furniture, for example, in the kitchen.

Great, if you cover a sink in the kitchen or a wash-stand in the bathroom with cardboard or rags. And women will appreciate, and the chipping of sanitary technicians with accidental fall of the working tool can be avoided.
Prepare a bucket of warm water, because, probably, you will not only have to change the gasket, but carry out the washing from the inside. Now you can shoot a home video on "How to change the gasket in the tap."
How to change the gasket - step by step guide
The first stage is a bit of theory. Currently, one of three types of cranes is used - a classic version equipped with a crane-beech, a mixer with a ceramic head or a single-lever mixer.
Gaskets fail in the first two types. Single lever mixer is equipped with a cartridge, which is either cleaned or is subject to replacement.
If your faucet has a metal crane-box, then one of the two parts - the gasket itself( the water drips from the nozzle with the tap closed) or the internal sealing ring( water leaks from under the head to the body) can fail.
Ceramic axle box is characterized by leakage of the sealing gasket. In this case, a repair kit is required.
Cooking tool. You will need a wrench or a wrench of a diameter corresponding to the nut of the crane, a screwdriver( most often a crest).
If there is a set of keys, then you will cope with the removal of the mixer, regardless of the size of the nut.
We disassemble the mixer. If you have never had to change the mixer, then before starting work is to see a video on its replacement. To dismantle the crane, first remove its handle.
The handle is most often attached to the valve head with a screw that is capped.
Usually the cap is red( for hot water) or blue( for cold).The cap is easily removed by means of a narrow sharp object( for example, a knife), the screw is untwisted with a screwdriver.
Now the handle is easily removed, access to the head is open. You can remove the head and detach the gasket.
We fix the problem. Carefully inspect the gasket. If you see holes in the middle or tears on the edges, then you need to change it to a new one. You can buy the gasket in any construction shop.
If you bring with you to the store the old, as a sample, you can buy the gasket of the required size.
If you can not find a suitable part for sale, then you can make it yourself from a piece of rubber the right thickness. However, rubber gaskets are, as they say, the last century.
Now in the course of gaskets from paronite( rubber mixture and the addition of powder inclusions).
They are much more reliable than rubber because they get wet, they will increase in volume, fill the space below the nut more efficiently, which will make it even more tight.
Check whether it is possible to use a new gasket, if it is suitable, very easily - the correctly selected gasket enters the groove with some effort, does not drop out, but does not protrude out of it.
Clean the inner surface of the faucet, the alignment of the parts, the thread and the nut from debris. Rinse the crane-axle from lime and rust.
When replacement and cleaning are carried out, you can proceed with installation. The faucet is assembled in the reverse order - the head is first installed, which is fixed with a wrench or a wrench.
During the tightening of the head, a tight fit should be achieved, but the twisting must be carried out without significant effort. Next, the handles are mounted. The last to place a decorative hood.

And now - check. When the mixer is assembled and connected, slightly open the common water valve and make sure there are no leaks and strength of the connections.
If the tap opens gently and evenly, and when the water is closed, the water stops flowing, then the system is assembled correctly.
If there is leakage or undermining of water, then the valve closes or opens with jerks, there is idle scrolling, then it is necessary to disassemble the mixer and make sure that the gasket lies flat, and the garbage does not get debris.
With the mixer open, slowly increase the water pressure in the system, opening the shut-off valve to the operating rate.
If there is no leakage even when the valve is completely open, then it can be said that the gasket has been replaced correctly.
We presented a step-by-step guide on how to replace the gasket in the faucet, but did not specify the reasons why this need to be repaired.
Flow is possible with an entire but incorrectly installed gasket. This is easily solved by disassembling the mixer and giving the correct position.
If the gasket is worn out, then almost always the reason for this is small grains of sand and tiny pieces of inner pipe lining.

If such debris falls under the gasket, it will be damaged. Change the gasket is easy and inexpensive, however, do not allow foreign objects into the water supply system.
This can be achieved by placing a coarse filter on the inlet of the water pipe and changing the old pipes to modern ones.
