DIY Faucet Repair: How to Fix a Leak by Disassembling the Faucet

Firstly, if you have a mixed faucet (which provides both cold and hot water), and you encounter a leak, you should turn off the water supply valve before starting any repairs. Here’s how to go about it:

How to Repair a Leaky Faucet at Home

1.Disassembling the Faucet

Once the water supply is turned off, prepare some plumber's tape. Look for a cover at the top of the mixed faucet; it contains screws. Use a screwdriver to remove the screws, and then grasp the handle firmly and pull it upwards.

Once the handle is removed, you will see the valve core, which is secured with threads to the base. Use an adjustable wrench to adjust it to a matching size and rotate it clockwise to unscrew the valve core.

After removing the valve core, you'll notice a rubber gasket inside. Carefully remove the old gasket and replace it with a new one of the same model. Reassemble the faucet in the reverse order of disassembly, and check if the leak persists.

2.Dealing with Constant Dripping

If the faucet continues to drip, you can control it through the main water supply valve. First, turn off this main valve; if there are separate valves for hot and cold water, make sure to turn them both off.

Prepare a flat screwdriver; loosen the screw on the handle using it. Insert the screwdriver into the handle’s fixing screw and turn it counterclockwise. Then, grasp the faucet handle and pull it up.

It may be that the gasket in the valve core has worn out. If that’s the case, replacing it with a new gasket of the same model can solve the problem. If the leak is at the connection point, check if the nut is loose and tighten it or replace it with a new U-shaped sealing ring.

3.For Push-Type Faucets

After turning off the water supply, you will also need to disassemble the components of the faucet. Replacing the worn-out gasket with a new one will prevent further dripping.

In summary, leaky mixed faucets are often due to worn-out gaskets. It’s quite common, so having spare gaskets of the same specifications ready for replacement can save you from further issues.
