- Rigorous engineering and testing helped generate the new series of RuleMate bilge pumps. Our pumps are tested to the highest standard, achieving rated performance at 12 volt, resulting in higher flow with better efficiency for the toughest applications. - The RuleMate automatic bilge pump turns on automatically when water rises and switches off again when it’s gone. Our pumps incorporate a market leading backup feature to tell you if something in the bilge has fouled or is blocking the pump giving peace of mind to the user. - All new RuleMate series pumps now come with check valves to minimize unwanted water in the bilge, anti-airlock vents to help maximize performance and a thermal cut out feature for added security.
