The compressor has a cut-in screw located the nearest to the motor. Help! Then it seemed there was a problem with the pressure switch. No water at Schrader valve so no bladder leak, right? 4 Pressure switch Setting the cut-out pressure 1. Shortcycling at the well pump is of course damaging too, but the pump can't fail to shut off if the main spring is set anywhere near the standard and all other things are normal. You wouldn't use a "Reducing valve" at the pump; normally the water pressure boosting pump either has an adjustable output pressure right at the pump or if it's a conventional pump and pressure tank the pump pressure control switch sets the pressure range by turning the pump on and off appropriately. When you then leave the pump off for a time that gives your well a chance to recover and that in turn might allow the pump to operate normally. 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. If the water pump apparent "short cycle" is say 1-3 minutesthis may be all your system can provide. Then make a second pass, cutting in all the way to the trim.
