I have 3/4 HP Sta Rite Pump that will not stop running. I have installed a new 30 to 50 pressure switch and 0 to 100 PSI gage. No leaks in the system. Pressure tube is clear. Bladder tank is set at 27 psi. Pump will buld pressure to 55 PSI and hold that 55 PSI after it is unplugged. Pump will not stop running with all valves shut. You can open the the faucet at the pump pressure will drop down to 35 PSI, close the faucet and the pressure will build back up to 55 PSI and keep running. Attempted to lower the cut out pressure on switch to 45 lbs and pump still will not cut out.
