14 Gallon - 24 Volt Marine SuperSump Shower Sump Tank - ST-6083

The Automatic SuperSump® Shower Sump Tank (Part #ST-6083) is a high-capacity drainage solution designed for superior performance and reliability in marine environments. Featuring a 14-gallon rotationally molded polyethylene tank with a 3/8” wall thickness, this unit is engineered to handle multiple drainage sources — including showers, tubs, and sinks — without the risk of overflow common in smaller sump systems.

Powered by a 24-volt, 2200 GPH pump, the SuperSump® provides automatic operation through a sealed, floatless switch with no moving parts for long-lasting dependability. Its mercury-free float actuation system ensures safe, efficient wastewater management, while a large back-flow valve on the outlet prevents pump cycling and maintains optimal performance.

The tank features four inlet ports — three 1-1/4” FPT and one 3/4” FPT — allowing for multiple drain hookups. The 1-1/8” and 3/4” outlet hose adapters provide installation flexibility, and the large deck plate with an O-ring gasket minimizes odors while allowing easy access for maintenance and cleaning.
