A noisy washer-type faucet is usually caused by a loose seat washer. To stop the noise, first turn off the water and take the faucet apart as described previously. If the washer is loose, tighten it or replace it. After threading the stem back into the faucet body, try moving it up and down. If it moves, the stem is worn and the entire faucet must be replaced. Some faucets are noisy due to poor design and construction. The only way to solve this problem is to replace the faucet with a quality one.
