The Rain Harvesting Commercial Downpipe First Flush Water Diverter utilises a dependable ball and seat system. As the water level rises in the diverter chamber, the ball floats, and once the chamber is full, the ball rests on a seat inside the diverter chamber preventing any further water entering the diverter.

The subsequent flow of water is then automatically directed along the pipe system to the tank. A slow release valve ensures the chamber empties itself after rain and resets automatically.
