How To Fix Drain Pipe Under Bathroom Sink

How to Fix a Drain Pipe Under a Bathroom Sink

A leaking drain pipe under a bathroom sink can be a frustrating problem, but it's one that you can usually fix yourself with a few simple tools and materials. Here's a step-by-step guide on how to do it:

1. Gather your tools and materials

You will need the following tools and materials:

Adjustable wrench
Plumber's putty
New washer (if necessary)
Bucket
Rags

2. Turn off the water supply

The first step is to turn off the water supply to the sink. You can do this by turning the handles on the shut-off valves located under the sink. If there are no shut-off valves, you will need to turn off the main water supply to the house.

3. Disconnect the drain pipe

Once the water supply is turned off, you can disconnect the drain pipe. To do this, use an adjustable wrench to loosen the nuts that hold the pipe in place. Be careful not to overtighten the nuts, as this could damage the pipe.

4. Inspect the pipe and washer

Once the drain pipe is disconnected, inspect it for any cracks or leaks. If you find any damage, you will need to replace the pipe. If the pipe is in good condition, check the washer. If the washer is worn or damaged, it will need to be replaced.

5. Apply plumber's putty

If the washer is in good condition, you can apply a bead of plumber's putty around the base of the pipe. Plumber's putty is a type of sealant that will help to create a watertight seal between the pipe and the sink.

6. Reinstall the drain pipe

Once you have applied plumber's putty, reinstall the drain pipe. Tighten the nuts that hold the pipe in place using an adjustable wrench. Be careful not to overtighten the nuts.

7. Turn on the water supply

Once the drain pipe is reinstalled, turn on the water supply. Check for any leaks. If you find any leaks, tighten the nuts that hold the pipe in place until the leak stops.

Tips

If you are not comfortable working with plumbing, it is best to call a plumber.
Always wear safety glasses when working with plumbing.
Be careful not to overtighten the nuts that hold the drain pipe in place. This could damage the pipe.
If you are replacing the washer, be sure to use a washer that is the same size as the old washer.
