The Automatic SuperSump® Shower Sump Tank (Part #ST-6050) is a durable, high-performance drainage solution designed for marine and RV applications. With a 4-gallon capacity and a 1250 GPH bilge pump, this system efficiently removes wastewater from your shower, tub, or sink, preventing overflow and maintaining a clean onboard environment.

Built with precision and strength, the SuperSump® features a rotationally molded polyethylene tank with a 3/8” wall thickness, ensuring long-term resistance to impact, corrosion, and vibration. Its floatless, sealed switch has no moving parts, providing dependable automatic operation with minimal maintenance.

This sump tank includes four inlet ports—three 1-1/4” FPT and one 3/4” FPT—to accommodate multiple drain hookups. The outlet is equipped with 1-1/8” and 3/4” hose adapters, while a large back-flow valve prevents excessive pump cycling. The deck plate with an O-ring gasket minimizes odors and allows convenient access for cleaning and servicing.
