COMMERCIAL DOWNPIPE FIRST FLUSH WATER DIVERTER

First Flush Water Diverters improve water quality and reduce tank maintenance by preventing the first flush of water, which may contain roof contaminants (such as sediment, bird droppings, spiders, insects, mosquito eggs and debris), from entering the tank. They help ensure cleaner water is available for use, which protects rainwater pumps and internal appliances. Commercial Downpipe First Flush Water Diverters are installed at the gutter downpipe or via a T-junction to a new or existing 150mm or 225mm downpipe.

of the Diverter Chamber #3.
3.  Fix the assembled chamber directly to the wall in the desired position
using the Wall Brackets #11.
