Commercial First Flush Water Diverters
Commercial First Flush Water Diverters are for larger 150mm and 225mm downpipe sizes. Installed via a T-join along the pipework that supplies water to your rainwater tank. Downpipe diverters help to direct this initial dirty rainwater away from your tank.
Note: Water diverted should be a minimum of 20 litres per 100 square metres of roof area (or 0.2L per m2).
