How to Fix a Leak Under the Bathroom Sink: A Step-by-Step Guide

A leaky bathroom sink can be a frustrating and inconvenient problem. Not only can it waste water and cause higher water bills, but it can also lead to damage to your bathroom floor and cabinetry if left untreated. Fortunately, fixing a leak under the bathroom sink is often a relatively simple task that can be completed in a few steps.

Step 1: Gather Your Supplies

Before you begin, you will need to gather the following supplies:

Wrench
Pliers
Bucket or bowl
Old towels
Replacement washers (optional)
Tubing
Putty knife
Plumber's Putty

Step 2: Turn Off the Water Supply

Once you have gathered your supplies, the first step is to turn off the water supply to the bathroom sink. This is typically done by locating the shutoff valve under the sink and turning it clockwise until the water supply is completely off.

Step 3: Drain the Sink

After the water supply has been turned off, the next step is to drain the sink. This can be done by opening the drain stopper and allowing the water to flow out into a bucket or bowl.

Step 4: Locate the Leak

Once the sink is drained, the next step is to locate the leak. This can be done by visually inspecting the pipes and fittings under the sink for signs of water damage. Once you have found the leak, you can proceed with the appropriate repairs.

Step 5: Tighten the Loose Connections

If the leak is caused by a loose connection, simply tighten the connection with a wrench until it is snug. Be careful not to overtighten the connection, as this could damage the pipes or fittings.

Step 6: Replace the Washer

If the leak is caused by a worn-out washer, you will need to replace the washer. To do this, use a wrench to loosen the nut that holds the washer in place and remove the old washer. Then, insert the new washer and tighten the nut until it is snug.

Step 7: Seal the Leak with Putty

If the leak is coming from a crack or hole in a pipe, you can seal the leak with plumber's putty. To do this, apply a thick layer of putty to the area around the leak and then smooth it out with a putty knife. Allow the putty to dry completely before turning the water supply back on.

Step 8: Turn the Water Supply Back On

Once the repairs are complete, you can turn the water supply back on. Check the sink for leaks by turning on the faucet and looking for any signs of water damage. If there are no leaks, your repairs are complete.

Conclusion

Fixing a leak under the bathroom sink is a relatively simple task that can be completed in a few steps. By following the steps outlined in this guide, you can save yourself time, money, and hassle.
