Flojet Water Booster System - 40PSI - 4.5GPM - 115V

The Flojet Water Booster System - 40PSI - 4.5GPM - 115V is a fully automatic marine water pressure pump engineered for boats, RVs, and marine vessels requiring reliable on-demand water delivery. After years on the water, serious boaters know that consistent freshwater pressure separates a comfortable cruise from frustrating low-flow headaches in the galley, head, and shower. This compact yet powerful system maintains constant pressure automatically, eliminating the need for manual intervention and delivering the dependable performance demanded by extended offshore trips and weekend getaways alike.

Built with a fully automatic pump mechanism and integrated inlet strainer, the Flojet booster generates pressures from 0 to 40 PSI with a maximum flow rate of 4.5 gallons per minute at 10 PSI, making it ideal for moderate-capacity marine water systems. The 115V electric operation suits standard onboard power supplies, while the pump's intelligent cutoff design reduces runtime and energy consumption by cycling only when demand is detected. This dual-benefit design—pressure regulation plus flow management—prevents tank surging and extends the lifespan of downstream fixtures, fittings, and hoses throughout your vessel's plumbing infrastructure.

Professional mariners, liveaboards, and recreational boaters upgrading aging or undersized water systems benefit most from this proven pressure booster, particularly those with larger freshwater tanks or multiple heads and galley stations running simultaneously. Installation is straightforward for anyone comfortable with basic marine plumbing—the compact 13 x 9 x 17-inch footprint fits neatly in engine rooms or lazarettes, while the 12.3-pound weight won't tax weight-sensitive vessels. Pair this system with quality hose clamps and appropriate inlet/outlet plumbing fittings to ensure years of salt-air reliability and consistent water pressure from the first sip to the last shower of your voyage.
