I have a problem with my bathtub pipes. The shower works great, but
if i run the tub the pipes starts banging really loud.
I thought it may have been an air lock, so i turned on all the faucets
in the house, but this did not work. Becuse my basement ceiling in
open at the this time, I can enusre the pipes are mounted properly.
It all seemed to start when i had a new hot water heater installed.
This does not happen with any other running water pipes in the house.
Any one have any idea what the problem may be?
