The RuleMate bilge pumps provide ultimate pumping performance, which helps keep your bilge clear of nuisance water, building on the genuine Rule design.
The new RuleMate bilge pumps operate using an internal level sensor. When water reaches 2″ (5cm), the pump will automatically activate, removing water from the bilge. When the water level reaches 3/8″ (0.9cm) the pump will turn off until the water level rises again.
