How to Fix a Dripping Kitchen Faucet

Faucets are workhorses of the kitchen, and eventually, the constant cycle of water and pressure wears down the internal seals. That rhythmic drip isn't just an annoyance; it is wasted water and a sign that the inner components of your faucet are failing. Fixing it is a mechanical process of disassembly and replacement that feels like magic once you see how simple the internals actually are. Done well, a faucet repair restores a smooth handle feel and a bone-dry spout. The secret lies in organized disassembly, so lay out every part in the order you remove them. If you take your time and verify your replacement parts against the old ones before reassembling, you will have a silent, efficient faucet in under an hour.

1. Shut Off Water First. Locate the shut-off valves under the kitchen sink and turn them clockwise until they are completely closed. Open the faucet handle to drain any remaining water from the lines.
2. Release the Handle. Identify the set screw, usually hidden under a small plastic cap or behind the handle. Use a hex key or screwdriver to loosen the screw and pull the handle assembly off the stem.
3. Extract the Cartridge. Use a wrench to unscrew the packing nut or retaining clip holding the cartridge in place. Pull the cartridge straight out of the faucet body using pliers if necessary.
4. Diagnose the Worn Part. Look for cracked O-rings, worn rubber washers, or a damaged cartridge. Bring the original part to the hardware store to ensure an exact match for the replacement.
5. Reassemble with New Parts. Slide the new cartridge or seals into the faucet body, ensuring they are seated perfectly. Tighten the retaining nut snugly, but do not overtighten, as this can crack plastic parts.
6. Test the Repair. Slowly turn the water valves back on under the sink. Turn the faucet on and off to flush out air, then leave it off to monitor for any remaining drips.
