A leaky sink handle can be more than just an annoying problem. It wastes several gallons of water a day and can cause permanent damage to your sink basin. The most common cause of a leaky sink handle is a worn out washer.
Turn off the water supply. Open the faucet to drain any water that is in the pipes.
Step2
Cover the drain with a towel so you do not lose any small parts down the drain.
Step3
Remove the sink handle. The screws for the handle may been hidden under a cap for decorative purposes. Remove the worn out washer.
Step4
Buy a new washer. Take the old washer to the store to ensure that you buy the correct item.
Step5
Install the new washer. Reattach the handle and screw it in place securely.
Step6
Run the water and check for leaks.
Tips & Warnings
To keep your sink handle from getting damaged, cover the wrench with a towel before undoing the faucet. This will protect the finish from getting scratched.
If your sink needs frequent washer replacements, the washer seat may need to be replaced. This is fairly inexpensive.
Don't try to fix a leaking faucet handle by pushing down on it harder. It will only fix the problem temporarily and it cause more internal damage to the faucet.
