Rain Harvesting 100mm First Flush Downpipe Diverter

The Rain Harvesting First Flush Downpipe Diverter takes the first flow of water which may contain contaminants from the roof and gutters, seals it off, then automatically diverts the remaining flow to the tank. First Flush Diverters help divert the first flush, through their design. They are installed using a T junction or high flow inlet to which the diversion chamber is fitted. As the chamber fills with the initial dirty water from your roof, a ball rises until it seals the inlet, allowing the rest of your rainwater, which is much cleaner, to flow directly to your tank.
