Jabsco 12V Single Stack Water Pressure System

The Jabsco 12V Single Stack Water Pressure System gives pressurized freshwater delivery for compatible onboard faucets, showers, and other fixtures. Its marine pressure-pump design responds to water demand and is intended to maintain useful flow across the vessel's freshwater plumbing without requiring manual pump control at each outlet.

Depending on the model, features such as an accumulator, multi-chamber diaphragm design, or variable-speed control help smooth delivery and reduce unnecessary cycling. The integrated system is designed around marine electrical protection and practical service access for boats with multiple freshwater outlets.

Confirm voltage, circuit protection, tank outlet, inlet filtration, hose size, pressure compatibility, fixture demand, mounting position, and service access before installation. Sanitize potable-water plumbing as required, protect the pump from freezing, and test every connection for leaks while operating fixtures through normal demand conditions. There is more in our bilge and water pumps.
