If the switch of the shower faucet in your bathroom leaks severely. I have decided to start repairing it myself and can inquire with the owner of the hardware store. Half of the sprinkler faucets are leaking, mainly due to damage to the valve core inside the faucet, which can be replaced separately:

New matching valve core (one) straight screwdriver, adjustable wrench

First, close the main inlet water valve and empty the water from the sprinkler head. The order of installation and disassembly is exactly opposite. When the copper cap is pressed onto the valve core, do not tighten it too tightly, as long as it does not leak water. Due to the fact that the outer shell of the valve core is usually made of plastic or PVC material, tightening it too tightly can directly crack the valve core.

Remove the handle of the faucet first.

There will be a plug on the handle of the faucet. Use a letter to pry off the plug; You will see a hole, insert a straight line into the hole, and loosen the screw that fixes the handle inside. No need to twist too much, just 5-6 turns. Then, pull the handle out with force.

Let's talk about unscrewing the cover on the faucet again. It is usually quite tight. To increase friction, cover it with a damp towel and twist it counterclockwise.

Remove the copper cap pressed onto the valve core. Use an adjustable wrench to unscrew the copper cap on the valve core and remove it. You will see significant cracks on the valve core, and the leakage of the faucet is caused by these cracks.

Check and clean the scale inside the faucet. Then install the newly purchased valve core device.

The order of installation and disassembly is exactly opposite
