Hello. I have a situation. I have a 1/2 hp Ace water deep well jet pump that I can't get to prime. The power went out for about 7-8 hrs and my pump lost prime. I have check/fill valves on well side (suction side) and on house side of pump. I filled both check pipes and filled top of pump itself and still no prime when normally it would work. Any ideas on what else I could do to get it to prime? Thanks in advance.
