Flojet Quiet Quad Water System Pump - 115VAC

The Flojet Quiet Quad Water System Pump – 115VAC (part number 04406043A) is a high-efficiency freshwater delivery system engineered for marine vessels, RVs, and off-grid applications. The four-piston design generates a steady 3.3 gallons per minute at pressures up to 40 PSI, making it ideal for galley operations, heads, and deck wash systems on boats ranging from center consoles to cruising sailboats. Unlike older diaphragm pumps that produce noticeable vibration and noise, this quad-piston configuration operates with minimal sound—critical when anchored in quiet coves or when extended operation on battery power matters.

Self-priming capability up to 2.4 meters of vertical lift eliminates the need for manual priming before each use—a practical advantage in shallow-basin installations or when the pump sits above the tank. The pressure-switch control automatically cycles the pump on and off as demand dictates, reducing runtime wear and battery draw on vessels relying on solar or auxiliary charging. Quick-connect plug-in ports streamline installation compared to threaded fittings, cutting labor time on new builds or system upgrades. Rated for intermittent duty, the motor handles the start-stop cycling typical of marine freshwater systems without overheating.

This pump suits weekend anglers upgrading older manual or gravity-feed systems, as well as live-aboard cruisers and offshore fishermen whose extended time on water demands reliable, quiet freshwater access. Marinas and boatyard technicians specify quad-piston pumps for retrofit projects because the performance-to-noise ratio justifies the investment over diaphragm alternatives. At 4.35 pounds and compact 5 × 4 × 13-inch dimensions, it fits tight engine compartments and below-deck locker spaces without the spatial penalty of larger displacement models.
