RULE 1100 GPH Shower Drain Box – Multi-Port Inlet Boat Shower Sump Pump System is a complete marine drainage solution designed to efficiently remove shower and grey water from boats, yachts, and other marine applications. This shower sump pump system combines a removable Rule 1100 submersible pump, integrated float switch control, and a multi-port inlet design to provide reliable water drainage in compact marine spaces. It is designed for use where shower water, sink water, or grey water needs to be collected and discharged safely overboard.

The system is available in two voltage variants: M99B-12 (12VDC) and M99B-24 (24VDC), allowing compatibility with different marine electrical systems. The M99B-12 model has an amp draw of 3.7 amps with a 7.5 AMP fuse size, while the M99B-24 model operates at 24VDC with an amp draw of 1.8 amps and requires a 4 AMP fuse size. The integrated Rule-a-Matic float switch automatically controls the pump operation, helping manage water levels inside the shower drain box without requiring constant manual switching.
