So I have a shallow well. Recently my water pressure will drop after running for about 405 minutes. Expansion tank is new and pressure is fine. New flojet pump. No blockage I can see. I ran the water while watching the gauge and itll drop to to 30psi, pump will kick on, then itll slowly drop to 20psi then ot 0psi fast all while pump is running. Takes pump about 2 minutes to reach 50 psi. What am I missing?
