Fixing a Leaking Bathroom Sink Pipe: A Step-by-Step Guide

A leaking bathroom sink pipe can be a frustrating problem, but it's one that you can fix yourself with a little effort. With the right tools and a step-by-step guide, you can stop the leak and get your sink back in working order in no time.

Here's a comprehensive guide to fixing a leaking bathroom sink pipe:

1. Gather Your Tools

Before you start, gather the tools you'll need:

Wrench
Pliers
Adjustable wrench
Plumber's putty
Teflon tape
Replacement washer (if needed)

2. Turn Off the Water Supply

Locate the water supply valves under the sink and turn them off to stop the water flow. This will prevent water from spraying everywhere when you remove the pipe.

3. Disconnect the Drain Pipe

Use a wrench to loosen the nuts that connect the drain pipe to the sink. Be careful not to overtighten or strip the nuts. Once they are loose, you can remove the drain pipe.

4. Disconnect the Water Supply Lines

Use the adjustable wrench to disconnect the hot and cold water supply lines from the sink. Cover the ends of the supply lines with a rag to prevent water from leaking out.

5. Remove the Sink

If the leak is coming from the base of the sink, you will need to remove the sink to access the pipe. To do this, loosen the nuts that connect the sink to the countertop. Once the nuts are loose, you can lift the sink off the countertop.

6. Inspect the Pipe

Once the sink is removed, you can inspect the pipe to find the source of the leak. The leak may be coming from a loose connection, a damaged pipe, or a worn-out washer.

7. Tighten Connections

If the leak is coming from a loose connection, simply tighten the nuts with a wrench. Be careful not to overtighten, as this can damage the pipe.

8. Replace the Washer

If the leak is coming from a worn-out washer, you will need to replace it. To do this, remove the old washer and replace it with a new one. Make sure the new washer is the right size and type for your sink.

9. Apply Plumber's Putty

If the leak is coming from the base of the sink, you can apply plumber's putty to seal the gap. To do this, roll out a small piece of plumber's putty and shape it into a cone. Place the cone over the hole in the pipe and press it down firmly.

10. Wrap Teflon Tape

If the leak is coming from the threads of the pipe, you can wrap Teflon tape around the threads to seal them. To do this, start at the end of the pipe and wrap the tape clockwise around the threads. Overlap the tape by about half and continue wrapping until you reach the base of the pipe.

11. Reassemble the Sink

Once you have fixed the leak, you can reassemble the sink. Start by placing the sink back on the countertop. Connect the water supply lines and drain pipe, and tighten the nuts. Finally, turn on the water supply and check for leaks.

Tips

If you are not comfortable fixing the leak yourself, call a licensed plumber.
Before you start working, cover the floor with a towel to protect it from water damage.
If the leak is coming from a damaged pipe, you will need to replace the entire pipe.
If the leak is coming from a loose fixture, tighten the fixture with a wrench or pliers.

By following these steps, you can fix a leaking bathroom sink pipe quickly and easily. With a little effort, you can get your sink back in working order and avoid costly repairs.
