Recently my well pump has failed to come on at the cut in point of the switch. The problem is only intermittent, occurring about once per day. By pressing the reset switch on the pump control box the pump usually resets, but on at least one occasion we had to reset the pump circuit breaker. What is going on? Is my well pump about to go or is it just the pressure switch acting up? Some particulars of my installation: We have a deep well (400'+), a Sta-rite pump, a Square-D pumptrol type FSG-2 35/55 psi, and a 35(?) gal. bladder tank. Also connected is a Rainsoft softening/filtration system with a sediment/iron filter.

Thanks in advance for any advice. Chris
