How To Change A Washer In Bathroom Faucet

The washer in a bathroom faucet is a small, round piece of rubber or silicone that creates a seal between the faucet handle and the valve stem. Over time, the washer can become worn or damaged, causing the faucet to leak. Replacing the washer is a relatively simple repair that can be done in a few minutes with a few basic tools.

Tools and Materials Needed

* New faucet washer * Adjustable wrench * Screwdriver * Plumber's putty * Rag

Step-by-Step Instructions

Turn off the water supply to the faucet.

This is typically done by closing the shutoff valves beneath the sink. 2.

Open the faucet to release any remaining water pressure.

Remove the faucet handle.

On most faucets, the handle is held in place by a screw or cap. Use a screwdriver to remove the screw or cap, then pull the handle straight up. 4.

Unscrew the packing nut.

The packing nut is located just below the faucet handle. Use an adjustable wrench to loosen the packing nut, then remove it by hand. 5.

Remove the old washer.

The old washer will be located on the end of the valve stem. Use a rag to grasp the washer and pull it straight off. 6.

Install the new washer.

Place the new washer on the end of the valve stem, then push it down until it is seated firmly against the valve seat. 7.

Reinstall the packing nut.

Hand-tighten the packing nut, then use the adjustable wrench to tighten it further. Be careful not to overtighten the packing nut, as this can damage the faucet. 8.

Reinstall the faucet handle.

Align the handle with the valve stem, then push it down until it is fully seated. Secure the handle with the screw or cap. 9.

Turn on the water supply to the faucet.

Open the faucet and check for leaks. If there are any leaks, tighten the packing nut further. 10.

Apply plumber's putty around the base of the faucet.

This will help to seal the faucet and prevent leaks.
