Johnson Pumps Shower/Graywater Sump Systems

Johnson Pumps Shower & Graywater Sump Systems

Managing wastewater aboard a vessel is one of the less glamorous — but absolutely essential — aspects of life on the water. Johnson Pumps, a globally recognized name in marine fluid management and part of the SPX FLOW group, brings decades of engineering expertise to the Shower/Graywater Sump Systems category with solutions purpose-built for the demands of modern boating.

Engineering reliable, high-performance marine pumping solutions for over eight decades , Johnson Pump Marine is renowned for advanced impeller technology and other key innovations, serving both leisure and commercial vessels with high-efficiency products for OEM fitting-out or aftermarket installation. That same depth of expertise flows directly into their shower and graywater sump offerings.

The Multi-Port Shower Sump System

Johnson Pumps' compact shower sump system is designed to meet the higher demands of today's boating industry, where more equipment is used — for example, fresh water systems incorporating showers, dishwashing machines, galley sinks, and more. Rather than requiring a separate pump for each drain point, the compact shower sump offers multiple inlet ports to handle sink, shower, and condensation drains all at the same time.

Several thoughtfully engineered features set these systems apart from generic alternatives:

• Ultima Automatic Float Switch: The shower sump turns on and off automatically using the Ultima switch , keeping the sump clear without any manual intervention.
• Built-In Check Valve: The check valve on the outlet stops water from flowing back into the tank , preventing odors and re-contamination.
• Easy-Clean Inlet Screen: An easy-to-clean inlet screen traps hair and debris before the pump clogs , simplifying routine maintenance.
• See-Through Lid: A tight-fitting, see-through lid allows for quick visual inspection without disassembly.
• Saltwater-Tough Construction: Fully submersible and saltwater tough , these systems are built to handle the corrosive marine environment without compromise.
• 3-Year Warranty: Backed by a 3-year warranty and made in the USA , the quality and durability of Johnson Pumps' shower sump systems reflect the brand's commitment to long-term performance.
