Rule-Mate 1100 Marine Bilge Pump (1100-GPH, 12-Volt)
The Rule-Mate Series of fully automated bilge pumps contain the pump and the non-mercury float switch in a single, compact housing. As the water level rises, so does the float switch, activating the pump when the water level reaches 2-1/8''. There is no on/off cycling and therefore, no power use until the pump comes on. Features include easy clean snap-lock strainer bases, silent, vibrationless operation, anti-airlock protection, stainless steel shafts, and no burn-out when run dry. 12VDC.
