How to Stop a Bathroom Sink Drain from Leaking

A leaky bathroom sink drain can be a nuisance, wasting water and potentially causing damage to your bathroom. Fortunately, fixing a leaky drain is often a simple task that can be completed in a few minutes with basic tools. Here are the steps on how to stop a bathroom sink drain from leaking:

Identify the Source of the Leak

The first step is to identify the source of the leak. Check the following areas:

Drain stopper: The drain stopper is a common source of leaks. If the stopper is loose or damaged, water can seep around it and leak out.
Washer: The washer is a rubber or plastic seal that sits between the drain flange and the sink. A worn or damaged washer can cause leaks.
Drain flange: The drain flange is the metal or plastic ring that connects the sink to the drainpipe. A loose or cracked flange can cause leaks.
Drainpipe: The drainpipe is the pipe that carries water from the sink to the sewer. A damaged or clogged drainpipe can cause leaks.

Gather the Necessary Tools

Once you have identified the source of the leak, you will need to gather the necessary tools to fix it. These tools may include:

Adjustable wrench
Pliers
Screwdriver
Plumber's putty
Replacement drain stopper (if needed)
Replacement washer (if needed)

Fix the Leak

The steps to fix the leak will vary depending on the source of the leak. Here are the steps for fixing common leak sources:

Drain Stopper:

Remove the drain stopper by unscrewing it counterclockwise.
Inspect the drain stopper for any damage or wear.
If the drain stopper is damaged, replace it with a new one.
If the drain stopper is in good condition, reattach it to the sink by screwing it clockwise.

Washer:

Remove the drain flange by unscrewing the bolts that hold it in place.
Inspect the washer for any damage or wear.
If the washer is damaged, replace it with a new one.
Reattach the drain flange to the sink by tightening the bolts.

Drain Flange:

Tighten the bolts that hold the drain flange in place.
If tightening the bolts does not stop the leak, you may need to replace the drain flange.

Drainpipe:

Check the drainpipe for any visible damage or clogs.
If the drainpipe is damaged, it will need to be replaced.
If the drainpipe is clogged, you can try to unclog it with a drain snake or chemical drain cleaner.

Test the Drain

Once you have fixed the leak, run water into the sink to test the drain. Check for any leaks around the drain stopper, washer, drain flange, and drainpipe. If there are no leaks, the repair was successful.

Preventing Future Leaks

To prevent future leaks, it is important to keep your bathroom sink clean and free of debris. Regularly remove any hair or soap scum from the drain stopper and strainer. You can also pour a cup of baking soda and vinegar down the drain once a month to help keep it clean and free of clogs.
