Accumulator TankThis 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, RV"s, motor caravans, coaches and similar applications.The Accumulator Tank smoothes water flow and reduces on/off 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 noticeable with instantaneous gas water heaters and with showers.The reduced on/off cycling reduces noise from the pump motor, and from shock pressures (pipe hammer). It also reduces battery drain, and gives longer pump life.Features:Internal BladderSmoother and More Even FlowQuieter Water SystemBetter Temperature ControlLonger Pump lifeLower battery DrainSimply fitted to new or existing systemsCompact sizeSnap-in port fittings include both: 1/2" barbed hose fittings and 1/2" threaded hose fittingsTank: hygienic, light, compact, impact and pressure resistant plastic construction Product : JABSCO 1 LITER ACCUMULATOR TANK W/ INTERNAL BLADDER Manufacturer : JABSCO Manufacturer Part No : 30573-0000 UPC : 671880026819
