How to Fix a Leaky Faucet in 15 Minutes (No Plumber Needed)

A dripping faucet wastes up to 3,000 gallons a year. Here is how to fix the three most common causes yourself.

What you need

An adjustable wrench, screwdriver, and a replacement cartridge or washer kit for your faucet model.

Step 1: Shut off the water

Close the valves under the sink and open the faucet to drain the line.

Step 2: Disassemble the handle

Pop the cap, remove the screw, and pull the handle straight up.

Step 3: Replace the cartridge or washer

Match the old part at the hardware store – this $5 part is the fix in most cases.

Step 4: Reassemble and test

Hand-tighten, restore water, and check for drips.
