How to Fix a Leaky Bathroom Faucet

Find the Leak Source

You want to stop a leaky bathroom faucet, but first, you need to know where the water escapes. Start by checking the area around the spout, handles, and base. Look for water stains, mold, or mildew. Sometimes, you see peeling paint or warped flooring near the sink. These signs point to hidden leaks.

Here are the most common causes of faucet leaks:

• Worn-out O-rings often cause leaks as they break down over time.

• Damaged washers let water seep through, especially in compression faucets.

• Faulty valve seats may corrode, leading to leaks around the spout.

• Loose or worn-out cartridges in ceramic disk faucets can fail to control water flow.

• High water pressure strains faucet parts, causing frequent leaks.

A visual inspection helps you spot trouble. You might notice bulging paint, musty odors, or damp spots. Focus on joints and fixtures. If you see water stains on ceilings or floors, the leak may be worse than you think.

Shut Off Water Supply

Before you fix a leaky bathroom faucet, you must turn off the water. This step keeps your bathroom dry and prevents water damage.

Follow these steps:

1. Find the water main shut-off valve. It sits near the water meter or where the main line enters your home.

2. Turn off the valve. Sometimes, it takes effort since it rarely moves.

3. Open the lowest faucet in your house. This clears out standing water.

4. Open the highest faucet to empty the plumbing system.

Not shutting off the water can lead to leaks and water damage. Always make sure the water is off before you start.
