How do I fix a dripping faucet?
Shut off the water under the sink, plug the drain, and disassemble the faucet handle to expose the cartridge or stem inside. In compression-style faucets, replace the rubber washer at the bottom. In cartridge faucets (most common since the 1990s), replace the entire cartridge. Cartridges are brand-specific, so bring the old one to the store to match it. In ball faucets, a small repair kit replaces the worn seats and springs; in ceramic-disc faucets, replace the disc cartridge or its rubber seals. Reassemble and turn the water back on slowly.
Step by step: fixing a dripping faucet
- Identify the faucet type: Compression faucets have separate hot/cold handles that screw down to stop water. Cartridge, ball, and ceramic-disc faucets usually use a single handle that pivots. Look at how the handle moves and the brand name on the faucet.
- Shut off the water: Find the shut-off valves under the sink. Turn them clockwise until they stop. Open the faucet to verify the water is off and pressure is relieved. If there are no valves under the sink, shut off the main water to the house instead. If a valve won't turn or starts leaking at the handle, stop there and call or text us.
- Plug the drain: Put a rag or plug in the drain so small parts don't fall down it. This sounds obvious, but losing a tiny set screw is a common way a simple repair turns into a bigger job.
- Disassemble the handle: Most faucets have a decorative cap that pops off, then a screw underneath. Remove the screw. Lift off the handle, then remove the nut or clip that holds the stem or cartridge in place. Take photos as you go so reassembly is easier.
- Replace the worn part: For compression faucets: replace the rubber washer at the base of the stem. For cartridge faucets: pull out the cartridge and bring it to the hardware store for an exact replacement. For ball faucets: replace the rubber seats and springs (sold as a repair kit). For ceramic-disc faucets: replace the disc cartridge or its rubber seals.
- Reassemble and test: Reverse the disassembly. Turn the water back on slowly. Test for leaks at the spout, base, and handle. If it still drips, the valve seat may be corroded and need resurfacing or replacement. That's a good point to stop and call (909) 312-4516 or text (909) 247-6791.
