How to Change a Washer in a Bathroom Sink Faucet

If your bathroom sink faucet is leaking, it may be time to replace the washer. The washer is a small, rubber or plastic ring that creates a seal between the faucet stem and the seat, preventing water from leaking. Replacing a washer is a relatively simple task that can be completed in a few minutes.

Tools and Materials

To replace the washer, you will need the following tools and materials:

Adjustable wrench
Phillips screwdriver
New washer
Petroleum jelly

Step-by-Step Instructions

To replace the washer, follow these steps:

Turn off the water supply to the faucet. There will be two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both valves clockwise to close them.
Open the faucet to release any remaining water. This will help prevent water from leaking out when you remove the faucet handle.
Remove the faucet handle. Most faucet handles are held in place by a screw. Locate the screw and remove it using a Phillips screwdriver. Once the screw is removed, the handle should come off easily.
Remove the packing nut. The packing nut is a large, round nut that is located under the faucet handle. Use an adjustable wrench to loosen the packing nut and remove it.
Remove the old washer. The old washer will be located under the packing nut. Use a screwdriver or your fingers to remove the washer.
Apply petroleum jelly to the new washer. This will help create a seal between the washer and the seat.
Install the new washer. Place the new washer over the faucet stem and seat it firmly.
Replace the packing nut. Tighten the packing nut using an adjustable wrench. Do not overtighten the packing nut, as this could damage the faucet.
Replace the faucet handle. Align the handle with the faucet stem and push it on until it is fully seated.
Tighten the handle screw. Use a Phillips screwdriver to tighten the screw that holds the handle in place.
Turn on the water supply to the faucet. Check for leaks around the faucet handle and packing nut. If there are any leaks, tighten the packing nut or adjust the handle screw.

Tips

If you are not sure what size washer to buy, take the old washer to a hardware store and ask for a replacement.
