I installed new fixtures in the master bath, which included a new shower, tub and two sink fixtures. Before the install there was no noise but now whenever a fixture is shut off or a toliet is flushed we get noise coming from the piping in the master bath. I drained the system, then turned the water back on and the noise went away but came back within 24 hours. Do I need to install water arrestors? If so can they be installed on the supply lines to one of the sink fixtures or should I cut access to the lines and install them behind the walls?? Help needed.
