The FLOJET 2840 Series Water Booster System is designed to provide steady water pressure and generous water flow. The pump is fully automatic with a built-in switch and check valve to maintain system pressure and will supply smooth water flow from a trickle to full flow. Typically used in large yachts, motor homes & bus conversions where high volume flow is required for multiple fixtures and amenities (e.g. washing machine, dishwasher, ice maker and water purifier).
