Rule RM1100B 24 Mate 1100GPH Automatic Bilge Pump 24V

Rule-Mate bilge pumps operate using an internal level sensor. For 500/800/1100 GPH models, when water reaches 2 inches (5 cm), the pump will automatically activate, removing water from the bilge. When the water level reaches 3/8 inches (0.9 cm) the pump will turn off until the water level rises again Bilges are not always clean and free from debris. If the Rule-Mate level sensor becomes fouled by debris or contaminated water, its unique back-up feature will prevent the pump from entering a run-on condition, protecting the battery while maintaining automatic operation.
