Why Use a Non-Return Valve?

A non-return valve prevents water from flowing back through your system when the pump stops — protecting the pump, maintaining system pressure, and preventing contamination between water sources. They’re particularly important when connecting multiple water sources or when the pump is positioned below the water tank.
