How to Fix a Leaking Bathroom Faucet

A leaking bathroom faucet is not only annoying but can also waste a significant amount of water. If you're experiencing this issue, don't worry - it's usually a relatively easy fix that you can do yourself with a few basic tools. Here's how to fix a leaking bathroom faucet:

Materials You'll Need:

Adjustable wrench
Phillips screwdriver
Flat-head screwdriver
Replacement faucet washer
Plumber's putty
O-rings (if needed)

Step 1: Turn Off Water Supply

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

Step 2: Remove the Faucet Handle

Use a Phillips screwdriver to remove the screw that holds the faucet handle in place. Once the screw is removed, pull the handle straight up to detach it from the faucet.

Step 3: Remove the Cartridge

Under the faucet handle, you will see a cartridge. This is what controls the flow of water through the faucet. Use an adjustable wrench to loosen the nut that holds the cartridge in place. Once the nut is loose, pull the cartridge straight up to remove it.

Step 4: Replace the Washer

The washer is a small, round rubber disk that sits inside the cartridge. Over time, the washer can become worn or damaged, causing the faucet to leak. To replace the washer, simply pry the old washer out of the cartridge and insert a new one.

Step 5: Apply Plumber's Putty

Once the new washer is in place, apply a thin layer of plumber's putty around the base of the cartridge. This will help to create a watertight seal and prevent leaks.

Step 6: Reinstall the Cartridge

Slide the cartridge back into place and tighten the nut that holds it in place. Make sure not to overtighten the nut, as this can damage the cartridge.

Step 7: Reinstall the Faucet Handle

Align the faucet handle with the cartridge and push it straight down until it is fully seated. Then, insert the screw and tighten it until the handle is secure.

Step 8: Turn On Water Supply

Turn the shut-off valves under the sink counterclockwise to turn the water supply back on. Check for leaks around the faucet. If there are no leaks, you have successfully fixed the leaking faucet!

Troubleshooting Tips:

If the faucet is still leaking after you have replaced the washer, it is possible that the O-rings need to be replaced. O-rings are small rubber rings that create a watertight seal between the cartridge and the faucet body.
If you are unable to remove the cartridge, you may need to call a plumber for assistance.
If you are not comfortable working on plumbing fixtures, it is always best to call a plumber to fix a leaking faucet.
