For the last day I have heard the well pump going off every hour or so. I have no leaks so I am thinking my one way valve before the pump is slightly open allowing pressure to return to the well. I have a 30 foot surface well with 1 1" solid line run in to the basement to a Diamind Jet pump. Am I on the right track in thinking this is my problem. If not I cannot think of anywhere else I am loosing pressure.
