A homeowner reports that their single-handle kitchen faucet is dripping continuously from the spout. You've diagnosed the issue to be a worn ceramic cartridge. After shutting off the water supply, what is the next step to service this type of faucet?

Question: A homeowner reports that their single-handle kitchen faucet is dripping continuously from the spout. You've diagnosed the issue to be a worn ceramic cartridge. After shutting off the water supply, what is the next step to service this type of faucet?

Answer options:

• Tighten the packing nut on the spout. ✅ Remove the decorative cap and handle screw.
• Apply thread sealant to the aerator.
• Adjust the hot limit stop.

Correct answer: Remove the decorative cap and handle screw.

Explanation: To service a single-handle faucet with a ceramic cartridge, the first step after shutting off the water supply is to remove the decorative cap (if present) and the handle screw to access the cartridge. Tightening a packing nut is for compression faucets, and applying thread sealant to an aerator or adjusting a hot limit stop would not resolve a dripping spout caused by a worn cartridge.
