Replace A Bathroom Sink Drain

Replacing a bathroom sink drain is a relatively simple plumbing repair that can be completed in about an hour. Before you begin, gather the necessary tools and materials: a new drain assembly, a wrench, a screwdriver, and a bucket. You may also need a pair of pliers if the old drain is particularly stubborn.

Once you have gathered the necessary tools and materials, follow these steps to replace the bathroom sink drain:

Turn off the water supply to the sink. This is typically done by turning off the valves located under the sink.

Place a bucket under the drain to catch any water that may leak out.

Using a wrench, loosen the nuts that hold the drain assembly in place. There are typically two nuts, one on the top of the drain and one on the bottom.

Once the nuts are loose, carefully remove the drain assembly from the sink.

Clean the drain hole in the sink. Remove any old caulk or debris that may be present.

Apply a bead of caulk around the base of the new drain assembly.

Insert the new drain assembly into the drain hole in the sink.

Tighten the nuts that hold the drain assembly in place.

Turn on the water supply to the sink and check for leaks.

If there are no leaks, the drain replacement is complete. If there are leaks, tighten the nuts further or apply more caulk until the leaks stop.

Replacing a bathroom sink drain is a relatively simple plumbing repair that can be completed in about an hour. By following the steps outlined above, you can easily replace a bathroom sink drain and save yourself the cost of hiring a plumber.
