Rain Harvesting Downpipe First Flush Advanced Water Diverter, part# WDDP120 diverts more contaminants and gives you greater control over water volume. The First Flush Diverters 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, a ball rises until it seals the inlet, allowing the rest of your rainwater, which is much cleaner, to flow directly to your tank.
Divert more contaminants and take greater control over your water volume with this next-generation First Flush Advanced Diverter.
This product comes with a Max Chamber Upgrade Kit that allows you to upgrade your first flush system from a 90mm chamber pipe into 100mm making it easier to divert the optimum first flush volume.
