Question: A plumber is servicing a single-handle kitchen faucet that drips continuously from the spout even when fully closed. The faucet has a ceramic disc cartridge. What is the most probable cause of this issue?
Answer options:
- Low water pressure in the supply lines. ✅ A cracked or worn ceramic disc cartridge.
- Incorrect installation of the aerator.
- Debris lodged in the spray head.
Correct answer: A cracked or worn ceramic disc cartridge.
Explanation: A continuous drip from a single-handle ceramic disc faucet is most often caused by a cracked or worn ceramic disc cartridge, which prevents the discs from sealing completely. Low water pressure or aerator issues typically affect flow, while debris in the spray head might restrict flow but not cause a constant drip from the spout when closed.
