I have a bored well with a 1 hp pump with pressure tank. Pump will not cut off. I replaced foot valve, then pressure switch. I checked pressure in pressure tank. Checked tank for water log. Checked the little pressure tube going to pressure switch. When running, there is good pressure at the faucet in the home. Pressure gauge on tank builds to 40. I have checked for leaks inside the home.What else could I check?
