Pump Check Valve Requirements
NOTICE
In order to ensure maximum system reliability and water delivery, check valves must be installed
in the drop pipe. The first check valve must be installed at the pump (the 18-70 LPM [5-25 USGPM]
pumps have a built-in check valve in the pump discharge) and additional check valves should be
installed every 30m (100 ft) of vertical pipe after the pump. See the pump owner's manual for
additional information.
