RULE 800 GPH Shower Drain Box – Multi-Port Inlet Boat Shower Sump Pump System is a complete shower drain management solution designed for marine shower installations where efficient removal of grey water is required. This boat shower sump pump system combines a Rule 800 submersible pump, automatic float switch control, and a multi-port inlet design inside a compact drain box to collect and discharge water from onboard shower areas. It is designed to help maintain a clean and dry marine environment by automatically pumping shower waste water away from the collection box.

The RULE 800 GPH Shower Drain Box is suitable for a wide range of marine applications, including boats, yachts, and other vessels with onboard shower facilities. The system features multiple inlet connection options, allowing flexible hose installation using 19mm (3/4″), 25mm (1″), or 29mm (1 1/8″) bore hoses with straight or 90º elbow configurations. Its sealed, clear screw-down cover provides easy visibility of the internal components, while the removable pump, strainer, and cover design allow convenient cleaning and servicing when required.

This marine shower sump pump system is available in two electrical variants: M98B-12 and M98B-24. The M98B-12 model operates at 12VDC with a 2.9 AMP draw and requires a 5 AMP fuse, while the M98B-24 model operates at 24VDC with a 1.5 AMP draw and requires a 2.5 AMP fuse. The system delivers an output capacity of 50 litres per minute (11 gallons per minute) with a maximum recommended discharge head of 2.5 metres.

Designed for practical marine plumbing installations, the shower drain box includes an integral non-return valve and a Rule-a-Matic float switch that automatically controls pump operation. The multi-port inlet design makes it easier to connect shower drains and manage grey water flow from different onboard areas. With dimensions of 230mm x 240mm x 130mm high, this compact boat sump pump system can be installed in limited spaces while providing reliable shower drainage performance.
