How to Fix a Leaky Faucet in 10 Minutes (DIY Guide)

A leaking faucet might seem like a small problem, but over time it can waste a surprising amount of water and increase your utility bills. The good news is that fixing a leaky faucet is one of the easiest DIY home repairs you can do. In most cases, the issue is caused by a worn washer, O-ring, or cartridge that needs replacement.

This guide will show you how to quickly diagnose and repair a dripping faucet using basic tools that most homeowners already have.

Common Causes of a Leaky Faucet

• Worn out rubber washer
• Damaged O-ring
• Faulty faucet cartridge
• Loose or corroded valve seat
• Mineral buildup inside the faucet

Tools You Will Need

• Adjustable wrench
• Screwdriver
• Replacement washer or cartridge
• Plumber’s tape
• Cleaning cloth

Step 1: Turn Off the Water Supply

Before starting any plumbing repair, turn off the water supply. Look under the sink for the shut-off valves and turn them clockwise. Turn on the faucet to release any remaining water pressure.

Step 2: Remove the Faucet Handle

Use a screwdriver to remove the screw holding the handle in place. Once removed, gently pull off the handle to expose the faucet stem or cartridge.

Step 3: Remove the Valve or Cartridge

Use an adjustable wrench to loosen and remove the valve or cartridge. Be careful not to damage surrounding parts while removing it.

Step 4: Inspect and Replace Worn Parts

Check the washer, O-ring, or cartridge for damage. If they look worn, cracked, or flattened, replace them with new parts. These replacement parts are inexpensive and available at most hardware stores.

Step 5: Reassemble the Faucet

After replacing the faulty parts, reassemble the faucet by reversing the steps. Tighten everything securely but avoid overtightening.

Step 6: Turn the Water Back On

Turn the water supply valves back on and test the faucet. If the repair was successful, the dripping should stop immediately.

Helpful DIY Tips

• Take a photo before disassembling so you remember how parts fit together.
• Bring the old washer or cartridge to the hardware store to match the size.
• Clean mineral buildup with vinegar while the faucet is open.

When to Call a Professional

If the faucet continues leaking after replacing the washer or cartridge, the issue could be deeper in the plumbing system. In that case, contacting a professional handyman or plumber is recommended.

Final Thoughts

Fixing a leaky faucet is a quick DIY repair that can save water, reduce your bills, and prevent further plumbing damage. With just a few tools and a replacement washer, most homeowners can complete this repair in under 10 minutes.
