Description

The Rule 51S is an automatic bilge pump designed for reliable water removal on boats. It features computerized water-sensing technology, eliminating the need for a separate float switch. The pump operates intelligently by waking up every 2.5 minutes to check for water, pumping until the bilge is dry if resistance is detected.
