Johnson Pump Viking Power 16 Grey Water Tank

The Johnson Pump Viking Power 16 grey water tank is designed to collect wastewater from showers, sinks, dishwashers, and similar onboard fixtures. It provides a centralized collection point before the wastewater is pumped onward, helping simplify plumbing layouts in marine sanitation systems. The tank is specifically prepared for use with the Viking Power 16 pump and includes pre-drilled mounting holes for that pump.

Multiple inlet ports in 19 mm, 25 mm, and 38 mm sizes provide flexibility when connecting different drainage sources. Outlet options are provided in 19 mm and 25 mm sizes, allowing the tank to be matched to the downstream plumbing arrangement. An included Ultima Switch supports automatic operation and can control a 12V or 24V pump drawing up to 20 amps.
