The next generation of Rule’s bilge pumps offers higher flow and backflow prevention that prevents water from reentering the bilge, and features a built-in thermal cut-off (TCO) that provides added protection for pump and vessel. Installation is easy in different configurations, due to the threaded discharge that allows for different port sizes. Rule bilge pumps are tested to the highest standard, including meeting performance testing at 12V vs. 13.6V, resulting in higher flow for the toughest applications.
