To shut off with a 40/60 pressure switch, 60 PSI is the same as 138'. That pump dead heads at 208'. So if your water pulls down lower than 70', that pump will not build to 60 PSI and the pump will melt down. The safe water level for that pump using a 40/60 switch is less than 50'. If the water doesn't pull down to more than 50', you cannot beat the price of that pump.
