The Rule LoPro bilge pump accommodates tight spaces and shallower bilges. Multiple operational modes are available to meet your specific requirements. 

The LP900S model features two automated modes. The first one engages the pump when the water level reaches your desired level of either 2” (5 cm) or 1.3” (3.25 cm); and the second one checks for water by briefly turning on the pump every 2.5 minutes.

The LP900D model has no sensors and uses a traditional float and/or panel switch for operation.
