Bathroom Sink Drain Leaking Around Threads: Easy Fixes for a Common Problem

A leaking bathroom sink drain can cause water damage to your bathroom vanity, floor, and even the ceiling below. It's a common problem that can be easily fixed with the right tools and materials.

One of the most common causes of a leaking bathroom sink drain is a loose or damaged washer. The washer is a small rubber or plastic disc that sits between the drain flange and the drain body. Over time, the washer can wear out or become damaged, allowing water to leak around the threads.

Another potential cause of a leaking bathroom sink drain is a cracked or damaged drain body. The drain body is the metal or plastic part of the drain that connects to the sink. If the drain body is cracked or damaged, it can allow water to leak out.

To fix a leaking bathroom sink drain, you will need the following tools and materials:

Adjustable wrench
New washer
Plumber's putty
Caulk gun
Caulk

Once you have gathered your tools and materials, follow these steps to fix the leak:

Turn off the water supply to the sink.
Place a bucket or bowl under the sink to catch any leaking water.
Use the adjustable wrench to loosen the drain flange.
Remove the drain flange and the old washer.
Apply a bead of plumber's putty to the threads of the drain body.
Install the new washer onto the drain body.
Reinstall the drain flange and tighten it with the adjustable wrench.
Turn on the water supply to the sink and check for leaks.
If there is still a leak, apply a bead of caulk around the base of the drain flange.

Fixing a leaking bathroom sink drain is a relatively easy task that can be completed in a few minutes. By following the steps outlined above, you can save yourself the cost of calling a plumber.
