A Rain Harvesting first flush downpipe water diverter keeps the dirtiest runoff out of your tank. This 90mm UPVC unit sends the initial roof wash, carrying dust, leaves and debris, away from your supply so cleaner water reaches the tank.

Size: 90mm
Colour: White
Material: UPVC
Type: First flush downpipe diverter

A slow release valve automatically drains the diversion chamber over time, resetting it for the next rainfall. The chamber capacity can be tailored by adding the right length of pipe. Understanding what first flush means in rainwater harvesting is simple: divert the first flush, protect the rest.

Outstanding value

Bought this on a bit of an impulse after seeing it on the site and really glad I did. Quality is much better than the price suggests — feels premium and well made. Ordered Monday and it arrived Wednesday in Sydney. Nothing loose or damaged. A few people have asked where I got it.

Satisfied customer

Had been looking at the Rain Harvesting for a couple of months. Rain build quality is obvious as soon as you open the box — feels solid and well finished. Easy to set up and works exactly as described. Delivery to Perth in only 3 days which is impressive. Will be buying more from SuperSaver AU for sure.
