      My home is on city water, it is about 13 years old. This summer, I replaced the electric water heater. I turned on all the water valves to get the air out of the lines, but I have a severe water hammer problem. When I run the water a lot, the problem will go away for a day or maybe two, then it will always return . I even installed some small devices that I found at Home Depot, but no help.. Maybe I am not getting the air out of the system .. But I think I was doing it correctly.. Any ideas about what is going on here ? Thanks

      Could be loose pipes, loose or insufficient pipe saddles, vibating components within a control or isolating valve.
      Check the piping system and valves as far as access permits and install additional pipe saddles where necessary.
      Should the pipes be flapping around in a wall cavity, a low pressure foam injected into the wall cavity through a pin hole in the wall cladding may solve the problem.
      A scan of the wall may be necessary to locate the position of the pipes so that the foam injection is correctly placed.
      Good luck.
