Causes of breakdowns

Consider the most common malfunctions and the causes of their occurrence.

Leak at the junction of the housing with the gander

This is one of the most common breakdowns. Frequent rotation of the gander in different directions leads to wear of the rubber gasket. To replace the gasket with a new one, you must perform the following steps:

1. Unscrew the fixing nut.
2. Remove the gander.
3. Remove the old worn gasket from the groove of the gander.
4. Replace the old rubber gasket with a new one.
5. Put the gander in place.
6. Wrap the thread on which the fastening nut will be installed with FUM tape in 2-3 layers.
7. Tighten the fixing nut.

As you can see, repairing the gander of the mixer in the bathroom with your own hands is a simple matter.

Water flows from under the control lever

This breakdown is often found in single lever mixers. The cause of the problem is a broken cartridge. You can eliminate the leak by disassembling the mixer and replacing the cartridge.

There are still signs of cartridge failure:

• The lever becomes difficult to control.
• Spontaneous change in water temperature.
• There is no supply of cold or heated water.
• The crane does not open and close completely.

The procedure for replacing a cartridge is as follows:

1. Remove the red-blue cap from the mixer body.
2. Using a small Phillips screwdriver, loosen or loosen the locking screw.
3. Remove the lever, unscrew the decorative cover.
4. Using an adjustable wrench, unscrew the nut that secures the cartridge inside the housing.
5. Remove the old cartridge.
6. Insert a working cartridge into the case, and then reassemble the mixer in the reverse order.

Important! The protrusions on the cartridge case must align with the recesses in the case. If they do not match, the tap will leak.

Dual valve device: valve is leaking

The cause of leakage of the valve is a violation of the integrity of the sealing washer, which is located on the crane box. Breakage and axle boxes may also occur. Replacing these parts is easy:

1. Remove the plug from the leaking tap.
2. Loosen the screw connecting the mixer body and valve.
3. Unscrew the axle box using an adjustable or open-end wrench.
4. Replace the axle box or o-ring.

Flowing switch from faucet to shower

Between the housing and the switch is a gasket, the wear of which is very likely. This provokes the leakage of the switch. The procedure is as follows:

1. Remove the switch (button) while holding the rod still using pliers.
2. Remove the stem and valve.
3. Remove the worn oil seal, replace it with a new one.
4. Assemble the switch in the reverse order.

Installation and repair of the shower faucet: the button or valve “shower faucet” is out of order

If the on button does not return to its original position, the cause is a spring failure. The disassembly procedure is similar to that described. It remains only to remove the damaged spring and install a new one in its place.

If the switch is faulty, and water spills out simultaneously from the tap and shower, then most likely the oil seal that is located on the switch rod has worn out. The repair procedure is as follows:

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

Water leaks at the shower hose

The cause of the leak is wear on the hose gasket. When the mixer leaks in this place, the gasket must be replaced:

1. Loosen the hose nut, then remove the remaining washer.
2. Replace it with a new paronite washer.
3. Before tightening the nut, wrap 2 layers of FUM tape on the thread.

Leaking hose and shower head connection leaking

This malfunction is eliminated elementary. There is a round gasket under the nut on the hose. It is easy to replace without even using any tools.

Weak water pressure, or do-it-yourself repair of the mixer spout:

• If the water from the tap flows in a thin stream, and the pressure is normal for the neighbors, then the reason is the clogging of the filter-aerator, which is located on the tip of the gander. Unscrew the filter carefully and check the pressure.
• If the pressure is normal without a filter aerator, then the “diagnosis” is correct. Rinse the aerator with running water and then reinstall.
