Question: We have a faucet that squeals when it is turned on partially. The squeal stops when the faucet is turned past a critical point. What causes the squeal and what can I do to prevent it?
Answer: A squealing water faucet is usually the result of a worn washer. When the stem is backed out (some one turns on the water) and the clearance between the frayed washer and the valve seat reaches a critical distance, the washer will vibrate and squeal like the reed in a wind instrument. As the valve is opened more, the space becomes greater and the reed effect _ and noise _ cease. Simply replace the washer.
