Fix Leaky Bathroom Sink Drain: A Comprehensive Guide

A leaky bathroom sink drain can be an annoying and wasteful problem. Fortunately, it's often an issue that you can fix yourself with a few simple tools and a bit of know-how. In this guide, we'll take you through the steps on how to repair a leaky bathroom sink drain.

1. Determine the Source of the Leak

The first step is to figure out where the leak is coming from. Wipe up any water around the sink and then turn on the water. Look for any water dripping from the drain, the pipes, or the base of the sink. Once you've found the source of the leak, you can start to fix it.

2. Tighten the Drain Stopper

If the leak is coming from the drain stopper, you can try tightening it. To do this, simply remove the drain stopper and then use a wrench to tighten the nut that holds it in place. Be careful not to overtighten the nut, as this could damage the stopper or the sink.

3. Replace the Washers

If tightening the drain stopper doesn't stop the leak, you may need to replace the washers. Washers are small rubber or plastic gaskets that create a seal between the drain stopper and the sink. Over time, washers can wear out and start to leak. To replace the washers, simply remove the drain stopper and then use a screwdriver or needle-nose pliers to remove the old washers. Apply a small amount of plumber's grease to the new washers and then insert them into place.

4. Tighten the Drain Pipe

If the leak is coming from the drain pipe, you can try tightening it. To do this, simply use a wrench to tighten the nuts that hold the pipe in place. Be careful not to overtighten the nuts, as this could damage the pipe or the sink.

5. Replace the Drain Pipe Gasket

If tightening the drain pipe doesn't stop the leak, you may need to replace the drain pipe gasket. The gasket is a rubber or plastic seal that fits between the drain pipe and the sink. Over time, gaskets can wear out and start to leak. To replace the gasket, simply remove the drain pipe and then remove the old gasket. Apply a small amount of plumber's grease to the new gasket and then insert it into place.

6. Caulk Around the Sink Base

If the leak is coming from the base of the sink, you can try caulking around it. To do this, simply clean the area around the base of the sink and then apply a bead of caulk. Smooth the caulk with your finger or a putty knife and then allow it to dry.

7. Call a Plumber

If you're unable to fix the leak yourself, you may need to call a plumber. A plumber will be able to diagnose the problem and recommend the best course of action.
