The SHALLOW WELL Unit spool is tapped for a suction drop pipe and has a vertical passage which equalizes the upper case and well casing pressures. The discharge body is tapped for the suction and concentric pressure pipes which are respectively connected to the pump suction and pressure ports. There is no passage extending from the pressure pipe to the well casing.
