Johnson Pump Aqua Jet II WPS 2.9 GPM Water Pressure Pump – 12V | MPN: 10-25008-03
Upgrade your vessel or recreational vehicle's plumbing system with the Johnson Pump Aqua Jet II WPS 2.9 GPM Fresh Water Pressure Pump – 12V (Part Number: 10-25008-03). Engineered by SPX FLOW, the Aqua Jet II series serves as a whisper-quiet, reliable heart for multi-fixture fresh water systems on small-to-medium boats, yachts, and RVs.
Unlike traditional 3-chamber or 4-chamber pumps that cause water hammer and pulsing at the faucet, the Aqua Jet II utilizes a 5-chamber diaphragm design. This delivers smooth, residential-like water flow with significantly reduced noise and pressure spikes. For ultimate longevity in harsh saltwater environments, the motor housing features an industry-leading triple-layer corrosion protection system—combining a zinc-manganese phosphate base treatment, electrocoating, and interior/exterior powder coating.
Key Features & Performance Advantages
-
Smooth 5-Chamber Diaphragm: Provides smooth, pulse-free water flow at up to 2.9 GPM (11 L/min), eliminating the need for bulky accumulator tanks in most small installations.
-
Triple-Layer Motor Corrosion Shield: Advanced surface treatment combines phosphate conversion coating, electrocoating, and powder paint to withstand marine humidity and salt spray.
-
40 PSI (2.8 Bar) Cut-Off Pressure: Built-in pressure switch automatically starts and stops the pump when a faucet or shower valve is opened and closed.
-
Plug-and-Play Servicing: Equipped with a weatherproof in-line wiring connector and a removable heavy-duty thermoplastic mounting bracket for effortless installation and maintenance.
-
Self-Priming & Dry-Run Safe: Capable of self-priming up to 6.5 feet (2 meters) and capable of running dry temporarily without damaging internal pump valves or diaphragms.

Frequently Asked Questions (FAQ)
Q: Do I need to install an accumulator tank with the Aqua Jet II 2.9 GPM pump?
A: While an accumulator tank is always beneficial for very low-flow demands, the 5-chamber design of the Aqua Jet II creates such a smooth, pulse-free water stream that an accumulator tank is generally not required for standard 1 to 3 fixture setups.
Q: Should I install an inlet strainer before this pump?
A: Yes! Always install a PUMProtector™ or equivalent 40-mesh inline inlet strainer on the suction side of the pump to prevent sand, plastic chips, or debris in your water tank from entering the internal valve chambers.
Q: Is this pump quiet enough to mount near a sleeping berth?
A: Yes. The 5-chamber technology and rubber-isolated mounting bracket significantly reduce mechanical vibration and operational noise compared to older 3-chamber diaphragm pumps.
