First Flush Delta In-Ground 100mm/4"

High volume First Flush Diverters, designed specifically for inground applications. Divert the dirtiest water and transform your Rain Harvesting system from “wet” to “dry” with this large volume inground first flush diverter.

The unique manifold design uses standard 100mm or 4" pipe to create a high capacity storage and diversion chamber for your first flush. Using these smaller pipe sizes makes it easier to source pipe and assemble the system, when compared to using large diameter pipe on traditional high volume diverters.
