Steps to Replace a Bathroom Sink Faucet Washer

The following steps will guide you through the process of replacing a bathroom sink faucet washer:

Turn Off the Water Supply.
Locate the shut-off valve for the bathroom sink and turn it off completely. This will prevent water from flowing into the faucet while you work.
Drain the Faucet.
Open the faucet handle to drain any remaining water from the faucet and pipes.
Remove the Handle.
Locate the handle screw or nut that secures the handle to the stem. Use a screwdriver or adjustable wrench to remove the handle screw or nut. Once removed, lift the handle off the stem.
Remove the Stem.
Depending on the type of faucet, there are a few ways to remove the stem: *
Screwed-in stem:
Use the adjustable wrench to loosen and remove the nut that secures the stem to the faucet body. *
Push-button stem:
If the stem is held in place with a push button or clip, simply press or release the button to remove the stem. *
Cartridge stem:
If the faucet has a cartridge stem, you'll need a faucet cartridge removal tool. Insert the tool into the cartridge hole and twist to remove the cartridge.
Inspect and Replace the Washer.
Once you've removed the stem, you'll see the washer at the end of the stem. Inspect the washer for signs of wear, such as cracking, tearing, or hardening. If the washer is damaged, replace it with a new one.
Reassemble the Faucet.
Carefully reassemble the faucet, following these steps: *
Insert the stem:
Carefully insert the stem back into the faucet body. *
Attach the handle:
Align the handle with the stem and reattach the handle screw or nut.
Turn on the Water Supply.
Turn the water supply back on and test the faucet for leaks. If any leaks persist, tighten the handle screw or nut and recheck.

If you're unsure about any step in the process, it's best to consult with a professional plumber. They can help you diagnose the problem and perform the necessary repairs safely and efficiently.

Additional Tips

Here are some additional tips for replacing a bathroom sink faucet washer:

Use Teflon tape:

When reattaching the stem to the faucet body, wrap a few layers of Teflon tape around the threads to create a watertight seal. *

Clean the faucet:

Before reassembling the faucet, take a moment to clean the stem, valve, and other components. This will help prevent debris from clogging the faucet later. *

Check for other problems:

If the leak continues after replacing the washer, there may be other problems with the faucet, such as a worn-out O-ring or a cracked valve. Consult with a plumber for further diagnosis. *
