Hi,
I attempted to adjust the Well Pump Pressure, the cut off raised (from 50 to 65psi) by turning the taller screw# 1 clockwise. However, the cut on does not raise clicking in at about 25psi. Is there anyway to increase the cut on pressure? According to the manual, the cut on should raise with the cut off. Thanks,

You turned the wrong nut. Turn the smaller one back to where it was, as best you can. Now use the larger center nut to turn up the pressure. It will raise BOTH the cut in and cut out pressures at the same time and will keep about a 20# differential. The smaller nut only raises the cut out pressure.
