Installing New Bathroom Sink Drain

Replacing a bathroom sink drain is a relatively simple plumbing repair that can be completed in about an hour. By following these step-by-step instructions, you can save yourself the cost of hiring a plumber.

Materials You'll Need

Before you begin, gather the following materials:

New bathroom sink drain
Adjustable wrench
Plumber's putty
Utility knife
Bucket
Rags

Step-by-Step Instructions

1. Turn Off the Water Supply

Before you begin working on the drain, turn off the water supply to the sink. There should be two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise until they are fully closed.

2. Remove the Old Drain

Place a bucket under the sink to catch any water that may leak out. Using an adjustable wrench, loosen the nuts that hold the old drain in place. Be careful not to overtighten the nuts, as this can damage the sink.

Once the nuts are loose, remove the old drain by pulling it straight up. If the drain is stuck, you may need to use a utility knife to cut through the old putty.

3. Clean the Drain Hole

Use a rag to clean the drain hole in the sink. Remove any old putty or debris that may be present.

4. Apply Plumber's Putty

Roll a small piece of plumber's putty into a rope and place it around the base of the new drain. The putty will help to create a watertight seal between the drain and the sink.

5. Install the New Drain

Insert the new drain into the drain hole and push down until the putty forms a seal. Tighten the nuts that hold the drain in place using an adjustable wrench.

6. Turn On the Water Supply

Turn on the water supply to the sink and check for leaks. If there are any leaks, tighten the nuts on the drain until the leak stops.

7. Clean Up

Wipe up any water that may have spilled during the installation. Dispose of the old drain and any other materials that you used.
