About one year ago a banging (hammering?) started occurring in the piping near the water heater when flusing any of three toilets in the house. The banging continues until the toilet tank is filled. The banging does not occur when opening and closing any other valve or faucet in the house. The system does have a pressure regulation valve and expansion tank. I have followed instructions to turn off main and drain all piping in the house. This has not corrected the issue. I am totally confused at to why this occurs only when any of the 3 toilets are running and only when one of the 3 toilets is running. Any help would be appreciated. What should be my next step? Replace expansion tank? Replace Pressure control valve? Replace ALL? toilet float valve?
