Question: During a routine inspection, a plumber observes a continuous drip from the cold water faucet in a residential kitchen. The homeowner reports that the faucet is a two-handle compression type. Which component is most likely causing the leak?
Answer options:
- The aerator
- The stem packing ✅ The washer
- The O-ring
Correct answer: The washer
Explanation: In a compression faucet, the washer is responsible for stopping the flow of water when the handle is turned down, sealing against the valve seat. A continuous drip indicates a worn or damaged washer. Stem packing prevents leaks around the stem, and O-rings are typically found in cartridge or disk faucets, or on the spout.
