Before testing, make sure the power supply is cut off. Cut in @ 30 PSI is ideal, but I do not want to raise the Cut off PSI anymore which is what happens when I turn down the big spring. Only one image can be added per comment but you can post as many comments, and therefore images, as you like. If you back the differential nut off 'too much', all that means is that the differential will be at its minimum which might cause short cycling. Setting the cut-in pressure. Each time I restore power to the well, I have to depress the Schrader valve (on the check valve on the pump inlet side of the check valve) until air ceases and water begins squirting. The larger nut (green arrow) on the larger spring in the pump pressure switch: changes cut-in AND cut-out simultaneously moving them both up (higher pressure) or down (lower pressure).
