How To Change Bathroom Sink Drain

A slow-draining or clogged bathroom sink is a common plumbing issue that can be easily fixed by replacing the drain. This is a simple task that can be completed in a few minutes with the right tools and materials.

Tools and Materials:

Adjustable wrench or pliers
New sink drain
Plumber's putty
Bucket
Cloth or sponge

Step-by-Step Instructions:

Turn off the water supply: Locate the water supply valves under the sink and turn them off to prevent water from flowing into the sink while you work.
Place a bucket under the sink: This will catch any water that may drain from the sink when you remove the old drain.
Loosen the old drain: Use an adjustable wrench or pliers to loosen the nut that holds the drain in place. Turn the nut counterclockwise to loosen it.
Remove the old drain: Once the nut is loose, you can pull the old drain out of the sink. Be careful not to drop it into the bucket.
Clean the drain hole: Use a cloth or sponge to clean any debris or old plumber's putty from the drain hole in the sink.
Apply plumber's putty: Roll a small amount of plumber's putty into a rope and place it around the base of the new drain. This will create a seal and prevent water from leaking around the drain.
Insert the new drain: Insert the new drain into the drain hole and hand-tighten the nut. Use the adjustable wrench or pliers to further tighten the nut, but be careful not to overtighten it.
Turn on the water supply: Turn the water supply valves back on and check for leaks around the drain. If you see any leaks, tighten the nut further.
Clean up: Wipe away any excess water or plumber's putty from the sink and surrounding area.

Tips:

If the old drain is stuck, you can use a penetrating oil to loosen it.
Be careful not to drop the old drain into the bucket, as it could damage the bucket or the drain itself.
Tighten the nut on the new drain securely, but do not overtighten it, as this could damage the drain or the sink.
If you are not confident in your ability to change the sink drain yourself, contact a plumber for assistance.

Replacing a bathroom sink drain is a simple task that can be completed in a few minutes with the right tools and materials. By following these instructions, you can easily fix a slow-draining or clogged sink and restore its functionality.
