If suddenly the switch for the mixer began to function

Plumbing equipment for receiving water treatment is usually divided into two types. In the first case, a special bathing tank is filled, and in the second, the washing process is carried out by applying small jets of water directly to the body. If it is the second option that is used, then sooner or later it will be necessary to repair the shower switch in the mixer, since it often fails.

Disassembly process

Determination of the cause of the fault is made only after a preliminary inspection of the components of the product. From this stage, the instruction attached to the product begins, which includes the process of removing the main mechanism.

During work operations must be carried out in a certain order:

1. First of all, a special cap is removed from the handle that performs purely decorative functions.. Under it is the mounting screw, which is unscrewed with a screwdriver.
2. The handle is carefully dismantled.. Before the eyes should appear box or any other mechanism. An eccentric or special cartridge can be installed inside.
3. The device is removed from the hole. If there is an axle box or a separate container, then the mechanism is easily removed completely. To remove the eccentric, you will need to do the additional operations described below.
4. If the shower switch for the mixer could not be removed completely, then the spout nut should be unscrewed for removal.. Removable body fragment gently turns away.

Note! If there is a need to replace the shower switch in the mixer, so as not to be mistaken when choosing an element, it is recommended to bring the shot mechanism to the store.

Main malfunctions

It is worthwhile to elaborate on the list of possible problems arising during the operation of these devices. All of them are quite realistic to do it yourself, without attracting specialists. The price of the main components is low, so the repair work will not cost as much as it might initially seem.

The appearance of smudges

In some cases, the shower switch flows on the mixer, which eventually leads to the appearance of rust on the plumbing fixtures. Usually the cause of a malfunction is a stuffing box, which over time can be damaged. The problem is solved by replacing it.

Below is the repair of a push-button shower switch in the mixer:

• Work begins with the overlap of the valves and disconnecting the spout and flexible hose.
• The button is removed from the stem, and the coating cannot be damaged.
• The adapter is removed using a steel rod.
• The valve with the stem is pulled out, after which the damaged oil seal changes.
• At the last stage of the assembly.

Uncontrolled flow of water

Sometimes there is a simultaneous flow of fluid directly into the spout of the faucet and the shower head. Such a phenomenon is characteristic of spool mechanisms when the gasket wears out. Replacing the sealing element provides the ability to completely eliminate this kind of malfunction.

If the upper gasket has fallen into disrepair, repair of the switch-mixer + shower-spout does not require complete disassembly. It is enough to remove the rubber layer with a thin key. Separate seals are not sold separately, but spare rings are usually supplied in the kit.

Replacing the gasket with a push button mechanism will be slightly different. During the work, the water supply is shut off and the spout is removed.

Directly into the hole of the adapter is inserted hex, which allows you to unscrew the retaining bolt. The button is removed, the screw is unscrewed, after which the plastic valve is pushed out.

Important points

Purchased products of this type will serve for a long time only if there are certificates of quality. When choosing, you should not save much, because in the future you can spend even more, carrying out frequent repairs. Save financial resources allows careful operation of the product.

When a malfunction is detected due to wear or damage to the sealing ring, it is not at all necessary to go to the store for a purchase. Similar elements can be made independently using a rubber tube.

It will be necessary to carry out disassembly work in any case, regardless of the cause of the breakdown, therefore it is best to look for instructions that usually come with the model of mixer being purchased.

Main types of mechanisms

Depending on the principle of operation, these devices can be divided into several types. The way to carry out repairs will largely depend on which element is installed in the mixer.

Below are the main options for mechanisms for switching modes.

• The spool mechanism is simple. It is most commonly found in valve type products. Between the two crane boxes, there is usually a special handle made of metal or plastic. To ensure tightness, such devices are equipped with rubber gaskets of a certain shape.
• The cork switch is practically not used at present.. It can be distinguished by a long handle, which is located in the central part of the device. The main component is a cork with a notch. When rotation is performed, the cavity is aligned with the inlet and outlet openings.
• The push-button device can be both in vertical and horizontal position.. This is the classic version for single lever mixers. To make the transition, just pull the handle up. Under the action of the pressure of water is automatically fixed flow.
• Cartridge analog is reliable and durable. When carrying out repairs, the container is completely changed, since finding suitable parts is quite problematic.

Attention! Especially popular is the mixer with the ceramic mode switch. Special plates are of high quality, thanks to which the device functions for a long time.

Final part

The text and graphic information presented above makes it possible to understand what to do if the shower switch on the faucet in the bathroom is broken. However, before starting work it is also recommended to carefully examine another source of information source - the video in this article.

Then it will be much easier to carry out repair activities.
