How to check a dripping faucet
Dry the faucet and surrounding counter. Then watch where the first drop appears with the tap off. A steady drip from the spout points to a different repair than water that starts at the base or underneath the sink.
Before buying a cartridge
- Identify the faucet’s brand and model. Check the original instructions or the manufacturer’s parts diagram for the correct cartridge.
- Locate both supply shutoffs. Confirm that both can stop the flow before opening the faucet.
- Use your model’s procedure for the cartridge. If you can’t find the model, photograph the faucet and visible markings for the manufacturer or a plumbing supplier.
Stop if either shutoff still lets water flow, the faucet twists when you apply force, or the retainer is seized.
