I have a adjustable Dema value right on the head of the pump,but it doesn't move my GPH gauge . I have tried everything I know. Choke the water supply,clean it and flush it out.It dose work a little I can feel the draw on the end of the draw tube. Would air in the water supply make it not work? I do have a water supply pump in line but I leave it off went I am working and also relieve the back pressure. I hope this board can help me!!Thanks Hook
