I'm going to assume that you have a "square D pumptrol(see image) and that it has a 20 PSI cut in and a 40 PSI cut off setting. First turnoff 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. One tall, one short. To increase the cut in pressure, turn the nut on the tall bolt down. To increase the cut out pressure,(that's the one that will give you more pressure) turn the nut on the short bolt down. This should give you the additional pressure you desire. Good luck
