The topic of this article is the elimination of simple malfunctions of valves and mixers. How to fix the faucet in the bathroom, if he started to turn? Is it possible to repair the valve, which has ceased to block the water? What to do with the mixer, which does not want to switch to the shower? We have to answer these and some other questions.

Fault categories

First, let us list the main categories, which include the typical problems of valves.

  • The valve does not hold water.

To clarify: in the framework of the article we will consider the malfunctioning of screw valves only. Ball fail very rarely; Cork is practically not used in apartments and private houses.

  • Water flows from under the valve stem.
  • The tap or the mixer lever does not block the water.
  • Water does not flow when the mixer taps are open.
  • Water does not switch to the shower.

Problems and Solutions

Vent

So, given: when the tap is turned off on the water supply, the water continues to flow to the mixer.

How does repairing a faucet in the bathroom do it yourself?

  1. Shut off and reset the corresponding riser water.

Tip: riser in the basement is easy to find, guided by its location relative to the flight of stairs.

  1. Making sure that the water is blocked, unscrew the valve head with an adjustable wrench.
  2. We clear the valve seat from deposits and debris. If necessary, change the gasket. Replacement in the absence of factory gasket can be cut from the car chamber.
  3. We assemble the valve by winding the head with a polymeric sealing thread, FUM tape or flax soaked in paint.
  4. We start the riser and check the operation of the valve.
When the valve is destroyed, you can rearrange the head from a similar or similar valve.

What should I do if the faucet in the bathroom is broken and water constantly flows along its stem? In most cases, it is enough to open the valve all the way. The stem thread with a washer at the same time presses the stuffing box or rubber seal to the gland, and the flow stops.

With the full development of the gland it needs to re-fill:

  1. Close the valve.
  2. Open the mixer tap to ensure that the valve is shut off.
  3. Consistently remove the lamb and turn off the gland nut.
  4. We take out the very gland - sleeve, pressed between the rod and the valve head.
  5. We wind around the rod one - two threads of a graphite packing.
  6. We assemble the valve in the reverse order.
Graphite gland. In our case, it dissolves into threads.

Cranbooks and cartridge

The next is the mixer. To begin, analyze the main causes of various leaks.

Malfunction Cause Elimination
Screw kranbuksa does not block the water in the closed position. Rubbish between seat and valve. Fully open and close the tap several times. Garbage, as a rule, makes the flow of water.
Wear pads. Shut off the valve on the liner; turn out kranbuksu; replace the gasket.
Screw kranbuksa turns. Worn thread of stem or axle box body. Cranbuxa is changing completely.
Ceramic Kranbuksa does not block the water. Chip of ceramic plates when trying to close the stuck dross bush. Cranbuxa is changing completely.
Single lever does not block water. Chip ceramic plate cartridge; breakage of plastic plate retainers.
  1. Shut off the valve.
  2. We take out the plastic cap from the back of the handle and unscrew the locking screw.
  3. Remove the handle.
  4. We turn away a decorative nut.
  5. We turn away a nut fixing a cartridge with a key.
  6. Change the cartridge for the same.
  7. We assemble the device in the reverse order.

Now - a line of various blockages.

  • How to clean the faucet in the bathroom, if the gander does not receive cold water? To begin with, it is enough to completely open both taps and with a finger, with effort to close the spout (gander). For most of the year, the pressure in the hot water system is greater than in the cold-water system, and the cause of the blockage is often taken out of backflow.
  • What to do if an attempt to force a blockage through a counterflow did not help? Shut off the water, remove the mixer and try to clean the pipes directly through the eccentrics with an improvised cable made of steel cornice. At one end of the string the handle is bent, which allows it to rotate; on the second, a hook the size of a pinhead is made, which literally scratches the course in lime deposits.
Lime and rust are the main causes of blockages.

How to screw the faucet in the bathroom after the pipes are cleaned? Use new gaskets under eccentric nuts; if necessary, completely unscrew the eccentrics (skewers), re-reel them with Tangit synthetic sealing thread and center on the mixer nuts.

  • How to clean the faucet in the bathroom, if with a minimum pressure and come cold and hot water? Usually the cause of the blockage becomes a filter on the gander. It is enough to manually unscrew it and clean it from the accumulated sand with a key.
Disassembling the filter.

By the way: blockages of the filter will become much less frequent if you take out stainless steel nets from it, leaving only a plastic aerator. The downside of the modification is that the sand will pass the filter without lingering in it.

Switch to shower

Here are the typical problems of switches on the shower.

Push button

If he does not switch the water partially or completely, then the reason is most likely in the destroyed rubber valve. Either the rubber ring on the valve changes, or, in the absence of appropriate parts, the switch completely. The price of a switch for domestic, Chinese and Polish mixers rarely exceeds 300 - 400 rubles.

A push button switch is often performed as a separate unit.

Leverage

If the lever switch does not switch to a shower or a gander with a limited course of the lever, the reason is the wear of the switch barrel or guides in the body of the mixer.

How to unwind the tap in the bathroom to replace the barrel?

  1. The switch lever is removed.
  2. Turning a gander and a nut with an adapter to the shower.
  3. The nut with stem seal is retracted.
  4. Removable stock with eccentric.
In the photo - this is the stage.
  1. The barrel is pushed out with a pencil or screwdriver through the top hole.
