This Accumulator Tank is intended for installation in any pumped water system controlled by a pressure switch. For example, PAR-MATE 2.5 or any Jabsco pressure pumps as found in boats, RVs, motor caravans, coaches and similar applications. The Accumulator Tank smooths water flow and reduces onoff cycling of the pump by lessening the variation in pressure and flow between the pump and the outlets in the system. The even flow of water gives better control of hot water temperature especially notice
