- Patented First Flush Plus tee prevents dirty water “skipping” over the traditional T-junction gap during heavy rainfall.
- Diverts water containing particles of matter into collection chambers installed on each downpipe.
- The Max Chamber Upgrade kit allows the chamber pipe size to be increased to 100mm/4” making it easier to divert the optimum volume of first flush.
- Automatic reset valve drains after rainfall events.
- Comes in kit form - just add your chamber pipe length
Protect your rainwater quality by diverting the most contaminated water that washes off your roof with the first few millimetres of rainfall using the Rain Harvesting First Flush Max.
The Max Chamber increases the volume of water you can catch in a smaller area – thanks to its large diameter chamber. It means you can divert more water with less space, giving you the flexibility to fine tune your system easily.
We've also included the Catch-All Tee to ensure you only catch the best quality water, and the Electronic Release Valve to give you the ultimate control over how regularly your first flush diverter activates.
