Step-by-step fix
-
1
Turn off the water supply
Look under the sink for two oval shutoff valves. Turn them clockwise until they stop, then open the faucet to drain the line.
-
2
Remove the handle
Pry off the decorative cap on top, remove the screw underneath, and pull the handle straight up.
-
3
Remove the worn part
For cartridge faucets, grip and pull the cartridge straight up. For compression faucets, unscrew the packing nut and replace the rubber washer.

4
Install the new part
Match the old part exactly. Apply plumber's grease to O-rings before installing. Ensure cartridge orientation matches the original.

Reassemble and test
Reverse the disassembly order. Slowly turn the shutoff valves back on. Run the faucet several times and wait 10 minutes before confirming the fix.
