Mixer classification

There are three types of faucets that can be used in the bathroom in one way or another:

  • Sensory. The control unit of the touch device is a photocell that sends a command to turn the device on / off. The structure of the sensor device is quite complex, and in case of a malfunction it can only be repaired by a specialist.

Causes of breakdowns

Before you fix the faucet in the bathroom, you need to know why, in fact, this malfunction occurred. The most common causes are:

  • Poor product quality. First of all, this is relevant for the products of dubious companies that use short-lived and low-quality components with consumables in production.
  • The use of obsolete materials. For example, rubber gaskets are inferior in strength to silicone and paronite. The latter do not crack upon drying and are deformed to a much lesser extent than rubber.
  • Heavily contaminated water in pipes.

Symptoms and Troubleshooting

Now we’ll take a closer look at typical malfunctions and how to fix a shower tap.

Important! All work related to repairs must be performed with a shut-off water supply.

Leaking water at the junction of the device and the gander

This breakdown is quite common, because the gander rotates in different directions. This leads to wear of the rubber gasket located in the groove of the gander. To cope with this trouble, you have to disconnect the gander and do such a repair of the crane with your own hands:

  1. Unscrew the fixing nut.
  2. Remove the gander.
  3. Remove the remaining worn gasket from the groove.
  4. Install a new gasket, put the gander in its original position.
  5. Wrap the thread with FUM tape in 2-3 layers.
  6. Tighten the fixing nut.

Leaking out of control lever

This breakdown is a common occurrence for lever mixing devices. It is caused by a cartridge malfunction. In addition to the flow of water, a faulty cartridge declares itself with such signs:

  • Difficult control lever.
  • Spontaneous change in water temperature.
  • Lack of water supply - hot or cold.
  • Incomplete overlap or incomplete opening of the tap.

The solution to this problem is to replace the cartridge. Proceed according to this algorithm:

  1. Remove the red-blue colored plug from the mixer body.
  2. Using a small Phillips screwdriver, loosen or loosen the locking screw.
  3. Remove the lever and the decorative cover.
  4. Using an adjustable wrench, unscrew the nut that holds the cartridge in the housing.
  5. Remove the worn cartridge, replace it with a new one.
  6. Reassemble the mixer in the reverse order.

Important! The protrusions on the cartridge housing must align with the recesses in the mixer housing. If you do not combine them, then the design will leak.

Button or valve “shower faucet” defective

If the button has stopped returning to its original position, the problem is a malfunction of its spring. Disassemble the switch in accordance with the algorithm already described, remove the broken spring and replace it with a good one.

The troubleshooting procedure is as follows:

  1. Remove the button.
  2. Remove the stem.
  3. Replace the worn oil seal with a whole.
  4. Assemble the switch.

Insufficient water pressure

If the pressure of the water in the house is normal, and the water in the bathroom flows weakly, then the matter is the clogging of the filter-aerator. Unscrew it and check the pressure. If the water began to go better, then the cause of the malfunction was found correctly. Rinse the aerator under running water and screw it into place.
