How to Fix a Water Leak Under the Bathroom Sink

A bathroom sink is one of the most used fixtures in your home. Wear and tear can eventually cause leaks, which are often a sign of a maintenance need. Fixing a water leak under your bathroom sink is a straightforward repair that can prevent water damage and save you money on your water bill.

Step 1: Identify the Source of the Leak

To fix a leak, you must first find its source. Turn off the water supply to the sink and open the faucet to release any remaining water in the line. Inspect the pipes and fittings under the sink for any visible leaks. Pay attention to the area around the drain, faucet, and water supply lines.

Step 2: Gather Your Tools and Materials

Once you have identified the source of the leak, gather the necessary tools and materials for the repair. You will likely need a wrench, pliers, a screwdriver, a bucket, a towel, some plumber's putty, and replacement parts if necessary.

Step 3: Fix the Loose Connection

If the leak is caused by a loose connection, simply tighten the fitting using a wrench or pliers. Over-tightening can damage the fitting, so apply moderate force.

Step 4: Replace Worn-Out Washers

If the leak is coming from the faucet, you may need to replace the worn-out washers. Turn off the water supply, remove the faucet handle, and replace the old washers with new ones. Apply plumber's putty to the threads of the new washers for a more secure seal.

Step 5: Fix a Leaking Drain

To fix a leaking drain, you will need to remove the drain stopper, clean the drain of any debris, and apply plumber's putty to the base of the stopper. Tighten the stopper back in place to create a watertight seal.

Step 6: Replace Supply Lines

If the leak is coming from the supply lines, you will need to replace them. Turn off the water supply and disconnect the old supply lines using pliers. Install the new supply lines and tighten the connections securely.

Step 7: Test the Repair

Once you have made the repair, turn on the water supply and open the faucet to check for any leaks. Inspect the area around the fix to ensure that the leak has been resolved. If you still notice a leak, repeat the process until the leak is fixed.

By following these steps, you can fix a water leak under your bathroom sink and prevent further water damage. If you are unable to locate or fix the leak, do not hesitate to contact a qualified plumber for assistance.
