So I ripped out my wall to rebuild my ensuite shower and I've just realized that the bathtub surround in the adjacent bathroom aside from having hot and cold supply lines to the shower valve, also has one into the pipe from the shower valve to the shower head.... does anyone know what's the purpose of it? Also every time I turn on the diverter for the shower head it could cause water hammer in the laundry room like 30 feet away, I wonder if this is what's causing it?
