First Flush Carrot 90mm Improves your rainwater quality by diverting the first flush of water from your roof to the storm water. By discarding the first flush of water it removes most of the debris that has been laying around prior to the rain fall. The Catch all T section ensures no water will skip across the Tee until the First Flush is complete – capturing the best quality water.
