• On-Demand: Turns on when pressure decreases
• Backflow Preventer: An internal check valve prevents reverse flow
• Multi-Fixture: Designed to handle plumbing systems with multiple fixtures
• 4-Chamber Diaphragm: Four independent pump chambers for a smooth, even flow
• Standard RV System: Mounts between the water tank and the distribution piping

An on-demand pump moves water through the f resh water system. It should be installed between the water storage tank and the distribution piping system. The pump turns itself on by an internal switch that activates when the water system pressure decreases. The internal pressure switch shuts the pump off when pressure is reestablished. Opening a faucet will reduce the internal water system pressure, and this turns on the pump.
