    I have a Man A Bloc water system, moentrol shower valves can not stop hammering
    When you turn on the water the valve hammers if you go all the way to hot or cold and turn back real slow to warm it does not hammer a hammer arrestor won't work because it's a manabloc if I adjust the water pressure it still does it the lower- the pressure the less sensivtive the hammering is- If I have 1 or 2 or 3 showers going they still hammer- I believe this is pressure balance problem does any know how to remove the balancing valve in a moentrol? Or the manabloc?

    Typical water hammer happens when you shut off the water. You must have a vibration. Your Manabloc could actually part of the problem.
