Crane box - these are the moving parts of the valve valve, assembled into a single removable structure. Thanks to this, it can always be replaced in case of a malfunction. Replacing the faucet bushing in the faucet is simple and can be done by anyone who can handle a wrench.
The purpose of the plumbing design is to open, regulate and lock the flow of water.
To eliminate the leak, you just need to change the faucet box, which is easily unscrewed from the mixer socket.
Preparation for work
Before replacing, you need to prepare open-end wrenches or an adjustable wrench. It is necessary to have a special plumbing tape for sealing threads, a screwdriver to unscrew the lamb (valve)
Replacing the faucet box in the bathroom faucet requires special care.
The sink should be protected with a piece of cardboard or plastic. This is done to protect plumbing from falling faucet box or wrench. And also to avoid metal parts getting into the drain.
Mistakes at work
Replacing the faucet box in the mixer is often associated with errors. Do not apply excessiveeffort when twisting it. There are cases of rust contamination of the thread. Then you should moisten this place with acetic acid or special cleaning products.
Be careful when doing so. When twisting, excessive force leads to deformation of the parts. You can even damage the thread. And this will already entail the cost of buying a new mixer.
Self-replacement
If the faucet leaks, you can call a plumber - this is the easiest option. But replacing the faucet box in the mixer with your own hands is not a problem.
And what if a person has never performed this operation and is afraid to do something wrong? In this case, you can read the instructions on the Internet and gain the first experience in replacing the axle box in the crane.
Old-type bushings with locking rod
A rubber seal is attached to the end of the stem to block the flow of water.
The advantages of this type of axle box are easy and cheap repairs. It is enough to change the compression rubber seal at the end of the stem.
The disadvantage is that this procedure has to be done quite often. At the same time, the faucet makes noise due to the vibration of the gasket, especially when it is worn.
The principle of operation of ceramic faucet boxes
They are in high demand. Advantages - noiselessness and reliability, they can work for five years or more. The wear period depends only on the quality of the water and the timely cleaning of the filter trap from dirt and debris. Howeverceramics are more expensive, and in case of failure, axle boxes require a complete replacement.
The principle of operation of the ceramic box is to align the hole of the rotary ceramic plug with the hole on the body. When the holes are aligned, the flow of water rushes through the faucet.
Details are airtight due to tight fit. That is why the quality of the water is so important, which should be free of solid particles that damage the surfaces of tight-fitting parts.
It is easy to distinguish the bushing on the gasket from the ceramic one. Ceramic closes in 2-3 turns, and at the same time a hard stop is felt. The compression gasket after closing the tap can be tightened further without a hard stop. And when opening, you need to make a few turns before the water comes out.
In order to buy a bushing crane, you need to know the type, thread sizes and manufacturer.
The best option is to take the old part, lamb and mounting screw with you to the store. In this case, the sellers will pick up the same one, or tell you where to buy it.
When purchasing a product, be sure to check whether the "native" lamb and screw fit it.
Dismantling the crane box
Before starting work on replacing the faucet box in the mixer, shut off the water inlet to the apartment or house. Locking devices are located next to the counters. If they are not in the apartment, then you will have to call a plumber to turn off the general water supply to the riser.
Regardless of which crane is used to replace the crane-bushings in a two-valve mixer - all water entering the house is turned off.
After the water is shut off, it is necessary to open the taps all the way. After the remaining water drains, you can begin to work on disassembling the faulty axle box.
First remove the flywheel. To do this, the protective cap is opened and the flywheel fastening screw is unscrewed.
After that, take a wrench and carefully loosen the thread. Then the axle box is unscrewed by hand.
The diagram of the device of the crane and its details are shown in the figure.
The new axle box is installed in reverse order. The entire repair procedure is the replacement of a crane box. Or a seal on the stem if the faucet is old and still usable.
At the end of the work, you need to turn on the water and check if the seals are leaking and how the plug works.
Replacing the faucet box in the Grohe mixer
The Grohe faucet is in high demand due to its reliability. It can serve for a very long time.
The only Grohe difference is that the lamb is attached not with a screw, but with a latch. In order to remove it, you need to squeeze the latch and pull off the lamb.
Dismantling and replacing the faucet box in the Grohe mixer is standard, and it is described above. Having unscrewed the faulty axle box, take a new one, screw it along the thread, tightening it onto the seal. But do not be zealous.
Then put a latch on the slotted mount, a lamb on it and, pressing on it,commit.
Conclusion
In order to properly replace, you need to know the type and dimensions of the bushing valve.
If the product is an old type, then only the compression gasket on the stem should be replaced. The bushing is removed, a new gasket is inserted, and the product is installed in place.
In order for the ceramic faucet box to serve for a long time, it is necessary that a filter trap be installed on the liner.
