Thank you for your question, and I am sorry to hear that you are experiencing an issue with your Delta faucet. We do recommend to try a few things to fix the noise issue. First, clean the aerator and check for debris. Unscrew the aerator counterclockwise to remove, using the wrench provided and soak in a solution of 50% white vinegar and 50% water solution. You can soak for an our or even overnight. Also try flushing the valve to make sure no debris has gotten stuck inside the faucet that maybe causing the noise. To flush:Turn the supply off to both the hot and cold-water lines. Once off, turn the handle on the faucet to the on position and leave it there to bleed the lines of any excess water. Next, disconnect the hot water supply line and place it inside of a bucket. Once the line is securely positioned into the bucket, turn on the cold-water supply.
Since the handle was left in the on position, the water will flow up the cold supply line, through the faucet cartridge and back down the hot water line into the bucket. Leave this flowing for at least 30 seconds. After flushing, reconnect the hot water line and repeat this process with the cold-water line to ensure all particles have been removed from both supplies.
