Jabsco Par-Max HD5 12V 5-GPM 60-PSI Water Pump

The Jabsco Par-Max HD5 12V 5-GPM 60-PSI Water Pump supplies pressurized fresh water to compatible onboard faucets, showers, and other fixtures. Its multi-chamber diaphragm design responds automatically to water demand, providing a practical pressure source for marine freshwater systems.

Par-Max models are built to balance useful flow with pressure control across varying fixture demand. Heavy-duty versions use upgraded motor and housing construction for improved durability, while compact standard models provide a smaller footprint for systems with fewer 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 under normal operating pressure. Look through the rest of our bilge and water pumps.
