The PumpBuddy valve is an outlet control device that allows variable minimum and maximum water level settings within a water tank when filling from a pump. For rainwater harvesting applications, it works as a backup water supply control valve, in the event demand exceeds rainfall. Features • Adjustable water levels save electricity & increase pump life • Full on, full off • No float switches, no power required (pump requires pressure switch) • Fewer parts mean fewer problems • Long tail available, no tank fittings
