Dripping Faucet: How to Stop the Leak
Most dripping faucets are caused by a worn cartridge, O-ring, or washer. The fix is the same whether you have a bathroom or kitchen faucet: turn off water, pull the handle, swap the worn part, reassemble. Parts cost $5–$20.
Step-by-Step Fix
- 1
Turn off the water
Close the shutoff valves under the sink (turn clockwise). Turn on the faucet to release pressure and drain residual water.
- 2
Remove the handle
Look for a decorative cap on top of the handle — pry it off with a flathead screwdriver to reveal a screw. Remove the screw and pull the handle straight off. Some handles just require a firm upward pull.
- 3
Identify your faucet type
Ball faucets have a rounded cap and single handle. Cartridge faucets have a cylindrical cartridge you can pull straight out. Compression faucets (older, two-handle) have a rubber washer at the bottom of the stem. Note yours before buying parts.
- 4
Replace the worn part
Cartridge: grip it with pliers and pull straight out, insert the new one in the same orientation. Ball faucet: replace the ball, springs, seats, and O-rings as a kit. Compression: unscrew the stem, replace the rubber washer at the bottom, and replace any worn O-rings on the stem.
- 5
Reassemble and test
Reverse your disassembly steps. Turn the shutoff valves back on slowly, then check for leaks at the handle base and spout. Turn the faucet on and off a few times — the drip should be gone.
⚠️ Safety Notes
- Take a photo before disassembly so you can reference part orientation.
- Bring the old cartridge to the hardware store — cartridges are brand-specific and must match exactly.
When to Call a Pro
If the shutoff valve under the sink is stuck or also leaking, don't force it — a plumber should replace it before you work on the faucet.
