    Let's kick that pressure up to where it belongs. The average house pressure will fall between 40 and 60 PSI. On a Square-D Pumptrol pump pressure switch, (see image)Turtn the larger spring clockwise to raise [both] cut-on and cut-off pressures.

    In other words, adjusting the pressure on this spring shifts the whole operating range of the switch up or down, but keeps the difference between cut-in and cut-out the same, whatever it happens to be (typically it's about 20 psi from the factory.
    Turn the smaller spring clockwise to raise the cut-out pressure only.
    In other words, adjusting the pressure on this spring shifts just the pump cut-out pressure up (clockwise) or down (counter-clockwise).
    This should give you the pressure you desire. Good luck, Tom
