How To Fix A Leak Under My Bathroom Sink

A leaking bathroom sink can be a nuisance, not to mention a waste of water. Fortunately, fixing a leak under your bathroom sink is usually a relatively simple task that can be done with a few basic tools and a little bit of time. Here are the steps you need to take:

1. Gather Your Tools and Materials

Before you start, you'll need to gather the following tools and materials:

Adjustable wrench
Plunger
Bucket
Old towels or rags
Flashlight
Replacement faucet or drain parts (if necessary)
Sealant

2. Turn Off the Water Supply

The first step is to turn off the water supply to your bathroom sink. This is typically done by turning the valve located under your sink. If you don't have a valve under your sink, you'll need to turn off the main water supply to your home.

3. Clear the Drain

If the leak is coming from the drain, you may be able to fix it by clearing the drain. To do this, use a plunger to try to dislodge the clog. If that doesn't work, you can use a drain snake to try to remove the clog.

4. Inspect the Faucet

If the leak is coming from the faucet, you'll need to inspect the faucet to identify the source of the leak. Look for any cracks or leaks in the faucet body or spout. You may also need to check the faucet's packing nut, which is located where the faucet handle connects to the faucet body.

5. Replace the Faucet or Drain Parts

If you find a damaged faucet or drain part, you'll need to replace it. To do this, follow these steps:

Turn off the water supply to your sink.
Disconnect the old faucet or drain part.
Apply sealant to the new faucet or drain part.
Install the new faucet or drain part.
Turn on the water supply and check for leaks.

6. Seal the Leak

If the leak is coming from a crack or hole in the faucet body or spout, you can try to seal the leak with sealant. To do this, follow these steps:

Clean the area around the crack or hole.
Apply sealant to the crack or hole.
Allow the sealant to dry according to the manufacturer's instructions.
Turn on the water supply and check for leaks.

7. Call a Plumber

If you're not comfortable working on your bathroom sink, or if you're unable to find the source of the leak, you should call a plumber. A plumber can diagnose the problem and make the necessary repairs.
