Step-by-step: Stopping a dripping faucet
Read the entire procedure before starting. Use the product manual and local code requirements where they are more specific.
- Identify the faucet brand and whether it uses a cartridge, ceramic-disc assembly, ball or compression washer; obtain the matching repair kit.
- Shut off the under-sink stops and open the handle to relieve pressure; cover the drain so screws cannot fall in.
- Remove the handle cap and fastener, photographing the order and orientation of parts.
- Remove the retaining clip or bonnet according to the model; do not force corroded parts or twist connected supply tubing.
- Inspect the cartridge, O-rings and valve seat; replace worn parts with model-compatible components and lubricate only with manufacturer-approved silicone grease.
- Reassemble, reopen water gradually and test full hot/cold travel and leak-free shutoff.
Common mistakes to avoid
- Generic cartridges that look similar may not fit or seal.
- Do not use petroleum grease on rubber seals.
- If the valve body is cracked or severely corroded, replace the faucet instead of forcing a repair.
