Replace Drain In Bathroom Sink

A bathroom sink drain is an essential part of the plumbing system, allowing water to flow out of the sink and into the drainpipe. Over time, drains can become clogged with hair, soap scum, and other debris, which can lead to slow drainage and even backups. If your bathroom sink drain is not draining properly, you may need to replace it.

Replacing a bathroom sink drain is a relatively simple plumbing repair that can be completed in a few hours. Here are the steps on how to replace a drain in a bathroom sink:

Materials You'll Need

New bathroom sink drain
Adjustable wrench
Plumber's putty
Flashlight

Instructions

Turn off the water supply to the sink. There should be two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both valves clockwise to turn off the water supply.
Remove the old drain. Place a bucket under the sink to catch any water that may leak out. Use an adjustable wrench to loosen the nut that holds the drain in place. Once the nut is loose, you can remove the drain by hand.
Clean the drain hole. Use a flashlight to inspect the drain hole and remove any debris that may be blocking the drain. You can use a small brush or a pair of pliers to remove any large pieces of debris.
Apply plumber's putty to the new drain. Roll a small piece of plumber's putty into a snake shape and wrap it around the base of the new drain. This will help to create a watertight seal between the drain and the sink.
Insert the new drain into the drain hole. Align the drain so that the drain holes line up with the holes in the sink. Press the drain into place and tighten the nut until it is snug.
Turn on the water supply and check for leaks. Open the shut-off valves under the sink to turn on the water supply. Check for leaks around the drain. If you see any leaks, tighten the nut until the leak stops.

Replacing a bathroom sink drain is a relatively simple plumbing repair that can be completed in a few hours. By following these steps, you can save yourself the cost of hiring a plumber.
