How To Replace A Washer In Single Handle Bathroom Faucet

Replacing a washer in a single-handle bathroom faucet is a relatively simple repair that can be completed in a few minutes. By following these essential steps, you can restore your faucet to proper working order.

Identifying the Washer Type

There are two main types of washers used in single-handle bathroom faucets: rubber washers and cartridge washers. Rubber washers are typically found in older faucets, while cartridge washers are more common in newer models. To determine which type of washer your faucet uses, remove the handle and inspect the stem.

Removing the Old Washer

Once you have identified the type of washer, you can remove the old one. For rubber washers, simply use a flathead screwdriver to pry the washer out of the seat. For cartridge washers, you will need to remove the cartridge assembly by unscrewing the retaining nut.

Installing the New Washer

Before installing the new washer, make sure to clean the seat and stem. Apply a small amount of plumber's grease to the new washer and then insert it into the seat. For rubber washers, use a screwdriver to press the washer into place. For cartridge washers, simply reinsert the cartridge assembly and tighten the retaining nut.

Reassembling the Faucet

Once the new washer is installed, you can reassemble the faucet. For rubber washers, simply replace the handle and tighten the screw. For cartridge washers, reinsert the handle and tighten the retaining nut.

Testing the Faucet

Once the faucet is reassembled, test it to make sure it is working properly. Turn on the water and check for any leaks. If there are any leaks, tighten the handle or retaining nut until the leak stops.
