I have a 15 foot shallow well. I installed a new 1hp Sears jet pump with a brand new check valve attached about 1 foot away from the pump. I can prime the pump in 30 seconds and pump water at 12.5 gpm for as long as I want to. When I close the valve, the psi remains steady at 55psi. The next day when I open the valve, water empties out of the pump, pressure drops below 40psi, which kicks on the pump. The psi slowly drop to 20psi, and after 20-30 seconds, the water stops coming and the psi drops to 0. Any ideas how I can keep the prime? Since the psi holds at 55 I don't think there could be a leak at the pump. Does that mean there is an air leak on the other side of the check valve?
