Rain Harvesting Downspout First Flush Diverter

Rain Harvesting Downspout First Flush Diverter

The First-Flush Diverter Rainwater Harvesting Kit intercepts and seals off the very first flow of water—often rich in roof-borne debris and contaminants—before it enters your storage tank. A slow-release valve ensures that the chamber empties itself after rainfall.

Ideal when paired with a leaf eater, this compact, easy-to-install kit lets you tailor the pipe length to match the volume of water you wish to discard, ensuring maximum efficiency with minimal upkeep.

Clearance Stock: This is the very last of this range and is on promotion while stocks last. Once these units sell out, we’ll be phasing out this model and switching exclusively to our new locally manufactured version.
