hey Guys, I have a pressure vacuum breaker for the irregation sysyem. the sprinklers were turned off over the winter and now when I turn on the valve, water just is blowing out the top of the PVB. and I cant seem to get any sprinkers to get any type of pressure either. (I assume all the pressure is lost from it coming out of the top of the PVB.) I am thinking I need a new PVB. (?) can anyone tell me if this is correct in thinking. hope if replaced then the sprinkers will work as normal? Genn
