Banging Water Pipes
Whenever someone turns on water (showers, faucets and toilets) on the third floor of my ten year old house, we hear banging sound from inside the walls and between floors. We replaced the leaky fill valve in one of the two toilets on the 3rd floor with Fluidmaster. Now when we flush the toilets, we do not hear the banging any more. But the problem persists with the faucets and showers. Any suggestions on where we should look next? Thanks.
