How to Fix a High Pitch Noise in a Kitchen Faucet
Your kitchen faucet may start producing a loud, high pitch noise; sometimes this noise is accompanied by a change in water pressure. If this happens in your kitchen, you may have a problem with the water pressure or a clogged water faucet. Fixing this problem is pretty easy and can be accomplished by the average do-it-yourselfer. Follow the steps below to fix the high pitch noise in your kitchen faucet.
Step 1—Check the Water Pressure
Before you get into anything too involved, you should first check the pressure of the water coming into the faucet from the shut off valve. Pressure that is too low or too high could cause this sharp, high pitch sound. Set the valve to the appropriate pressure and see if the squeaking stops.
Step 2—Blow Air into the Faucet
If adjusting the water pressure doesn’t solve the problem, you will need to blow compressed air into the faucet to clear any lodged debris. In order to do this, you will need to remove the supply line from under the sink. You will then have easy access to the inside of the faucet. Blow compressed air into the faucet until whatever has clogged it breaks free.
