I am a caretaker at a summer recreation facility, The water system is drained in winter months. There is a deep well that provides 90+ G.P.M. and a 500gal holding tank. I have already charged the system once this month and repaired all leaks. The water is treated the first time, then drained and flushed. There is a shut off valve between the well pump and holding tank. The second time I turned on the well pump I thought I had the shut off valve open when in fact I didn't. Pump was on for a maximum of 45 sec. It blew out the diaphragm on the pressure control switch (square D 30-50). I replaced the pressure switch wiring it the way the switch instructions said, which was slightly different than it was originally wired. I turned on the well pump, It filled the tank and and it cut out right at 50psi. I started to fill a large hot water and watched the pressure drop to see the cut in Pressure. At 30psi the pressure switch started clicking rapidly. Tried wiring the way it was originally with same results. Did I burn out the pump? pump relay? Still kicking myself.
