Fix A Bathroom Sink Drain Leak

A leaking bathroom sink drain can be a frustrating and annoying problem. Not only can it waste water and increase your utility bills, but it can also damage your bathroom fixtures and floors. Fortunately, most bathroom sink drain leaks are relatively easy to fix with a few simple tools and materials.

Before you begin, it is important to identify the source of the leak. Common causes of bathroom sink drain leaks include a worn-out washer, a loose drainpipe, or a damaged gasket. Once you have identified the source of the leak, you can begin to make repairs.

Tools and Materials

Adjustable wrench
Pliers
Flathead screwdriver
New washer
New drainpipe (if necessary)
New gasket (if necessary)
Plumber's putty
Bucket or bowl
Rags

Step-by-Step Instructions 1. Turn off the water supply to the sink.

The first step is to turn off the water supply to the sink. This will prevent water from leaking out while you are working on the drain.

2. Remove the drain stopper.

The next step is to remove the drain stopper. This can usually be done by simply pulling it up. If the drain stopper is stuck, you can use a flathead screwdriver to pry it loose.

3. Inspect the washer.

The washer is a small, rubber disc that sits between the drainpipe and the sink. Over time, the washer can become worn out and start to leak. If the washer is worn out, you will need to replace it.

4. Remove the drainpipe.

If the washer is not the source of the leak, you will need to remove the drainpipe. To do this, simply loosen the nuts that hold the drainpipe in place and pull the drainpipe out of the sink.

5. Inspect the gasket.

The gasket is a small, rubber ring that sits between the drainpipe and the sink. Over time, the gasket can become damaged and start to leak. If the gasket is damaged, you will need to replace it.

6. Apply plumber's putty.

Before you reassemble the drain, you will need to apply a thin layer of plumber's putty to the rim of the sink. Plumber's putty will help to seal the drain and prevent leaks.

7. Reassemble the drain.

Once you have applied plumber's putty, you can reassemble the drain. Simply insert the drainpipe into the sink and tighten the nuts that hold it in place. Then, replace the washer and the drain stopper.

8. Turn on the water supply to the sink.

Once you have reassembled the drain, you can turn on the water supply to the sink. Check for leaks around the drain. If there are any leaks, you may need to tighten the nuts that hold the drainpipe in place or apply more plumber's putty.
