Fix a Dripping Faucet
A drip every second wastes ~3,000 gallons a year. Cause depends on faucet type — modern faucets are usually cartridge or ceramic disc; ball faucets are less common today; compression faucets are mostly older homes and utility sinks.

Materials
- +Bring the old part to the hardware store for an exact match
- +For new O-rings. Do NOT use petroleum jelly or Vaseline — they swell and destroy rubber O-rings. Danco silicone faucet grease is the standard.
Steps
-
1
Identify your faucet type
Single-handle pulls = cartridge. Single-handle that wiggles = ball. Two-handle with separate hot/cold = either compression (older, with rubber washers) or ceramic disc (newer).
-
2
Shut off the water
Close both supply valves under the sink. Turn the faucet on to relieve pressure and confirm water is off.
-
3
Take the handle apart
Pop off the decorative cap on top of the handle (small flathead pry). Underneath is a screw — remove it, then lift the handle straight up.
Tip: Take a phone photo at each step. Reassembly is much easier with reference shots. -
4
Pull the cartridge or replace washers
For cartridge: unscrew the retaining nut, pull the cartridge straight up. For compression: replace the rubber washer on the bottom of the stem.
-
5
Install the new part
Line up the new cartridge with the alignment notch and seat fully. Grease any O-rings before installing.

Reassemble and test
Reverse your photos: cartridge → retaining nut → handle → screw → cap. Turn the water on slowly and check for leaks at every connection.
