How To Replace A Washer In Bathroom Sink Drain

The washer is a small, rubber component that sits in the sink drain and creates a watertight seal. Over time, the washer can deteriorate and cause the sink to leak. Replacing a washer is a simple and relatively inexpensive repair that you can do yourself.

Materials

New washer
Adjustable wrench
Bucket or bowl
Plumber's putty (optional)

Safety Precautions

Before you begin, turn off the water supply to the sink. Then, open the faucet to release any residual water from the lines.

Step 1: Remove the Drain Stopper

Locate the drain stopper in the center of the sink. Use a flathead screwdriver or a coin to pry the stopper out of place.

Step 2: Remove the Drain Assembly

Beneath the drain stopper, you will see a metal drain assembly. Use an adjustable wrench to loosen the nut that holds the assembly in place.

Step 3: Remove the Old Washer

Once you have removed the drain assembly, you will see the old washer. Use your fingers or a pair of pliers to remove the washer from the bottom of the drain assembly.

Step 4: Apply Plumber's Putty (Optional)

If you want to create a more watertight seal, you can apply a small amount of plumber's putty around the bottom of the new washer.

Step 5: Install the New Washer

Place the new washer into the bottom of the drain assembly. Make sure that the washer is properly seated and that it is facing the correct direction.

Step 6: Reinstall the Drain Assembly

Screw the drain assembly back into place. Use the adjustable wrench to tighten the nut, but do not overtighten it.

Step 7: Reinstall the Drain Stopper

Put the drain stopper back into place and press down firmly to secure it.

Step 8: Turn on the Water Supply

Turn on the water supply to the sink and check for leaks. If you see any leaks, tighten the nut on the drain assembly further.

Tips

If you are having trouble removing the old washer, you can try using a pair of needle-nose pliers.
If you do not have any plumber's putty, you can use petroleum jelly instead.
If you are still having problems with the sink leaking, you may need to call a plumber.
