Submersible Pump Pressure Drop
Posted by Mike Schiffer on December 09, 2002 at 11:51:10:
My submersible pump is set for 30/50 pounds at the pressure switch. The problem is that it turns on at
30 pounds, then turns off at 50 - immediately when it turns off, the pressure drops 10 pounds to 40. Is
there some sort of check valve in the pump that isn't closing immediately when the pump turns off or
could it be something else? Thanks for any advice...
