— 【1 】—The faucet still leaks water after the valve core is closed

This phenomenon may be caused by the loosening of the pressure cap causing the valve core to become loose and unable to seal the water. The solution is to remove the handle and decorative cover, and tighten the pressure cap again. Another possibility is that the rubber ring at the bottom of the valve core is deformed. Can not seal the water, the solution is to take out the valve core, check the bottom rubber ring, reset it and reinstall it.

— 【2 】—Water seeps from around the valve core

This phenomenon may be that the spool is loose or displaced. The solution is to remove the spool and install it again.

— 【3 】—Water seeps from the middle part of the valve core

What should I do if the faucet leaks?

— 【1 】—The push-type faucet leaks

Step 1. Close the water inlet valve. Remove the small screws on or behind the faucet handle to remove the handle fixed on the faucet body. Some screws are hidden under metal buttons, plastic buttons, or plastic sheets, which snap into or screw into the handle. As long as you turn on the button, you will see the handle screw on the top.

Step 2: Remove the handle and check the parts of the faucet. Use large slip joint pliers or an adjustable wrench to remove the packing nut, being careful not to scratch the metal. Turn the spool or shaft in the same direction as when you turned on the faucet to unscrew them.

Step 3: Remove the screws holding the washer. If necessary, use penetrating lubricant to loosen the screws. Check the screws and valve core, and replace them if they are damaged.

Step 4: Replace the old washer with an identical new washer. New washers that almost exactly match the old washers generally keep the tap from dripping. You should also pay attention to whether the old gasket has a bevel or flat, and replace it with the same new gasket. A gasket designed only for cold water will swell violently when hot water flows through it, blocking the water outlet and slowing down the flow of hot water. Some gaskets can work in both hot and cold water, but you should make sure that the replacement gasket you buy is exactly the same as the original one.

Step 5: Fix the new gasket to the valve core, and then reinstall the parts in the faucet. Rotate the spool clockwise. After the spool is in place, reinstall the packing nut. Be careful not to scratch the metal with the wrench.

Step 6: Reinstall the handle and put the button or disc back. Turn on the water supply again and check for leaks.

— 【2 】—Water tap leakage caused by the sealing ring of the tap

Dripping occurs when the faucet is closed; water leakage occurs when there is water flowing through the faucet. If you see water pouring from around the handle, your faucet is leaking; the first thing to do is to make sure the packing nut of the faucet is tight, but be careful not to scratch the nut with pliers or wrench.

If you find that the cause of the water leakage is not the loose nut, then you need to replace the sealing ring. The sealing ring of the faucet can be a tight sealing ring composed of one or more O-shaped rubber rings, or it can be something like a string or soft metal wire wrapped around the valve core under a packing nut.

— 【3 】—Water leakage caused by valve seat of faucet

If you change the gasket and the faucet still drips, then there may be a problem with the valve seat of the faucet. A damaged gasket may cause the valve seat of the faucet to be worn out by the metal valve core and become uneven, or the deposition of chemical substances in the water may form a residue, which prevents the gasket from being completely compressed with the valve seat.

Steps: Insert the valve seat tightening wrench into the valve seat, and then turn it counterclockwise. Once you remove the old valve seat, make sure that the new valve seat you bought is exactly the same as the original one. If the seat cannot be removed, insert a seat cover that can slide into the proper position of the old seat and provide a seal. Two types of valve seat rollers or sanders that can flatten worn valve seats.

— [4]—The O-ring of the faucet causes the faucet to leak

The faucet in the kitchen has one or more O-rings to prevent water from gushing around the outlet. If the O-ring is worn out, you will see water flowing out of the bottom of the outlet every time you turn on the faucet.

Step 1: Turn off the water supply, turn counterclockwise and remove the threaded coupling nut that fixes the water outlet. Be sure to wrap the nut with tape to prevent it from being scratched by pliers or wrenches.

Step 2: After removing the coupling nut, lift the water outlet up and take it out of the water outlet seat. You can see these rings in the water outlet seat.

Step 3: Replace the problematic ring with a new one of the same size. Reassemble the faucet.
