Faucet washers requiring replacement in a kitchen sink faucet may indicate wear on which part of the faucet?

• A. Seat
• B. O-ring
• C. Stem
• D. Handle

Answer: (A)

The key idea is that the washer’s job is to seal against the valve seat. When the seat becomes worn or grooved, the washer can’t form a tight seal, so leaks persist and washers may wear out more quickly, leading you to replace them. The seat is the contact surface that the washer presses against to stop flow, so wear here directly affects the effectiveness of the washer. Other parts like O-rings seal around the stem or the handle and stem wear affects how the valve operates, but they aren’t the surface the washer seals against. So repeated washer replacement points to wear on the valve seat.
