I'm going to assume that you have a "square D pumptrol. First turn off the power at the breaker box, then pull the cover off the pressure switch and you will see two spring loaded bolts secured with nylon nuts,(see image) One tall,( #1) one short.(#2) To increase the pressure, turn the nut on the tall bolt down. This will increase both the cut in and the cut out points. If you just want to increase the cut out pressure without increasing the cut in point then turn the nut on the short bolt down. Good luck, Tom
