How to Fix a Leaking Faucet Step by Step (Beginner-Friendly Guide)
A dripping faucet may seem like a small issue, but it can waste hundreds of gallons of water per year and increase your water bill. The good news? Most leaking faucets can be fixed in less than one hour — even if you have no plumbing experience.
Tools & Materials You Will Need
- Adjustable wrench
- Screwdriver (flat & Phillips)
- Replacement washer or cartridge
- Teflon (plumber’s) tape
- Small towel or cloth
Step 1: Turn Off the Water Supply
Locate the shut-off valves under the sink and turn them clockwise to stop the water flow. Open the faucet to release any remaining water pressure.
Step 2: Identify Your Faucet Type
Knowing your faucet type helps you replace the correct part:
- Compression faucet: Two handles, older style
- Ball faucet: Single handle with rounded cap
- Cartridge faucet: Smooth handle movement
- Ceramic disk faucet: Modern and durable
Step 3: Disassemble the Faucet
Remove the handle using a screwdriver. Carefully take out internal parts and place them in order on a towel to avoid losing anything.
Step 4: Replace the Damaged Part
Most leaks are caused by worn washers, O-rings, or cartridges. Take the old part to a hardware store to find an exact replacement. Install the new part securely.
Step 5: Reassemble and Test
Reassemble the faucet in reverse order. Turn the water back on slowly and test for leaks. If water drips, gently tighten the connections.
Common Mistakes to Avoid
- Over-tightening parts (can cause damage)
- Using the wrong replacement part
- Forgetting to turn off the water
When to Call a Professional Plumber
If the faucet still leaks after replacing parts, or if you notice corrosion, pipe damage, or water under the sink, it’s best to contact a licensed plumber to avoid bigger problems.
Conclusion
Fixing a leaking faucet is one of the easiest and most cost-effective plumbing repairs you can do yourself. With basic tools and patience, you can save money, reduce water waste, and gain confidence in DIY plumbing.
