A while back our shower diverter went out and it would sound like the pipes were vibrateing in the wall a little over a yr ago we had my mothers bathroom remolded and new sink was put in among other things we have never had probs before in her bathroom but after they put in the new sink when you turn the water on it would make the same noise as the shower the noise occurs when you turn the cold water on if you move the handle towards the warmer side the noise quits would greatly appreciate any help or advice that you maybe able to offer
