Rain Harvesting 90mm Downpipe Interceptor Rainwater Diverter for Tank Protection | DPIN01

Protecting your rainwater tank from roof runoff pollutants is one of the most important steps you can take to maintain stored water quality, and the Rain Harvesting 90mm Downpipe Interceptor makes that job refreshingly simple. At first glance it looks like any other downpipe fitting — and that is precisely the point. Its discreet, low-profile design integrates naturally into your existing downpipe system without the visual bulk of large valves or sliding gate mechanisms. Yet beneath that understated appearance is a genuinely clever piece of engineering that gives you direct control over what enters your rainwater tank.

The key to the Downpipe Interceptor’s effectiveness lies in its rotating middle section. When you need to divert water away from the tank — whether it is the first flush of a rain event carrying roof debris, a period of ember activity during fire season, or simply a time when you want to keep dirty runoff out of storage — a quick lift and rotate of the centre section is all it takes. No tools, no complicated adjustments, and no need to interfere with the rest of your downpipe setup. The water is cleanly redirected away from the tank, protecting your stored supply from leaves, dirt, ash, and other harmful substances that commonly wash off Australian rooftops.

Installation is equally straightforward. The top of the Downpipe Interceptor glues directly onto your existing 90mm downpipe, making it a practical retrofit for already-established rainwater systems as well as a smart inclusion in new builds. Because it integrates within the downpipe run itself rather than sitting alongside it as a separate component, it requires minimal space and keeps your guttering and downpipe arrangement looking clean and uncluttered. There are no large external housings or protruding mechanisms to contend with during installation or day-to-day use.

For Australian homeowners in areas prone to bushfire ember risk, heavy leaf fall, or general roof contamination, the Rain Harvesting 90mm Downpipe Interceptor offers a fast and dependable first line of defence for tank water quality. Its simple twist-to-divert operation means the whole household can use it confidently, and its seamless integration with standard 90mm downpipe systems makes it one of the most practical additions to any rainwater harvesting setup.
