Rule Mate Automatic Bilge Pump
Model No. RM1100B
The 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.
Bilges are not always clean and free from debris. If the level sensor becomes fouled by debris or contaminated water, RuleMate0s unique back up feature will prevent the pump from entering a run-on condition, protecting the battery while maintaining automatic operation.
