FIRST FLUSH: Divert the initial runoff to ensure only the highest quality water is captured.
AUTO DRAINING: Featuring a slow release valve which will automatically drain the chamber ready for the next rainfall.
JUST ADD PIPE: The First Flush with Catch All Tee includes everything you need to install - just add 3" pipe for the chamber.
CUSTOMIZE YOUR DIVERSION VOLUME: The system is easily customised by adding the length of pipe to suit your first flush requirements.
Ever wonder about the first flush of rain off the roof? Lots of 'stuff' dissolved in it. So now send that water to the collecting chamber (to drain off slowly) and collect the better water that follows.
