First Flush Water Diverters
First Flush Water Diverters improve water quality and reduce tank maintenance by preventing the first flush of rainwater, which may contain roof contaminants, from entering the tank.
Choose a first flush diverter to suit your needs
Note: Water diverted should be a minimum of 20 litres per 100 square metres of roof area (or 0.2L per m2).
