Post/Wall First Flush Water Diverters

Post/Wall First Flush Water Diverters are mountable on a wall, post or stand. With larger chambers than standard 90mm/100mm downpipe diverters, they are often used in conjuction with larger rooftops where more litres in the “first flush” of rainwater need to be diverted.

Note: Water diverted should be a minimum of 20 litres per 100 square metres of roof area (or 0.2L per m2).
