How to Repair a Bathroom Sink Faucet

A leaking bathroom sink faucet can be a major annoyance, not to mention a waste of water. If you're handy, you can save yourself the cost of a plumber by repairing the faucet yourself. Here's a step-by-step guide on how to do it:

Tools and Materials You'll Need:

Adjustable wrench
Phillips screwdriver
Flathead screwdriver
Allen wrench (if necessary)
Replacement washer (if necessary)
Plumber's putty
Toothbrush
White vinegar
Rags

Step 1: Turn Off the Water Supply

Before you start working on the faucet, you need to turn off the water supply. There should be two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both valves clockwise until they are completely closed.

Step 2: Disassemble the Faucet Handle

Once the water supply is turned off, you can start disassembling the faucet handle. Most faucet handles are held in place by a screw. Use a Phillips screwdriver to remove the screw and then pull the handle straight up to remove it.

Step 3: Remove the Cartridge

Once the handle is removed, you will see the cartridge. The cartridge is the part of the faucet that controls the flow of water. To remove the cartridge, use an adjustable wrench to loosen the retaining nut. Once the nut is loose, you can pull the cartridge straight out.

Step 4: Inspect the Cartridge

Once the cartridge is removed, inspect it for any damage. If the cartridge is damaged, it will need to be replaced. If the cartridge is not damaged, you can clean it with a toothbrush and white vinegar.

Step 5: Replace the Cartridge (if necessary)

If the cartridge is damaged, it will need to be replaced. To replace the cartridge, simply insert the new cartridge into the faucet body and tighten the retaining nut. Do not overtighten the nut, as this can damage the cartridge.

Step 6: Reassemble the Faucet

Once the cartridge is replaced (or cleaned), you can reassemble the faucet. To reassemble the faucet, simply insert the handle back into the faucet body and tighten the screw. Then, turn on the water supply and check for leaks.

Step 7: Apply Plumber's Putty (optional)

If you notice any leaks around the base of the faucet, you can apply plumber's putty to seal the leak. To apply plumber's putty, simply roll it into a rope and then place it around the base of the faucet. Press the putty into place with your finger and then smooth it out with a wet rag.

Tips:

If you are not comfortable repairing the faucet yourself, you can always call a plumber.
Before you start working on the faucet, make sure to read the manufacturer's instructions.
If you have any questions, you can always consult with a hardware store employee.
