Original price was: $193.$161Current price is: $161.
The Rain Harvesting WDDP02 100mm First Flush Downpipe Diverter Kit is a PVC-constructed diverter system designed to keep contaminants out of your rainwater tank by redirecting the initial, most polluted runoff away from your water supply. It features a slow-release valve that automatically empties the chamber between rainfall events, ensuring the system is always reset and ready. All necessary fittings are included, so all you need to add is a length of pipe to complete your custom storage chamber.
Maintaining clean, safe rainwater starts at the very first drop — and that’s exactly what the Rain Harvesting 100mm First Flush Downpipe Diverter Kit is engineered to do. Every time it rains, the initial flow of water washes fine organic and inorganic particles, dust, bird droppings, and debris off your roof surface. This diverter captures and redirects that first, most contaminated flush away from your rainwater storage tank, so only cleaner, filtered water makes it through to your supply.
One of the standout features of this kit is its automatic slow-release valve. Once the chamber fills with the initial flush of water, the valve gradually drains it away on its own — no manual emptying required. By the time the next rainfall arrives, the chamber is clear and the system is fully reset, giving you consistent protection across every single weather event without any ongoing maintenance effort on your part.
The WDDP02 is also designed with flexibility in mind. You can easily customise the size of your storage chamber by simply adjusting the length of standard 100mm PVC pipe you attach — allowing you to tailor the system to the specific catchment area of your roof. All the fittings you need for a complete installation are included straight out of the box, making this an accessible and practical upgrade for any Australian home with a rainwater harvesting setup.
Constructed from durable white PVC, this diverter is built to withstand outdoor Australian conditions while blending neatly into standard downpipe installations. Whether you’re setting up a new rainwater system or improving an existing one, the Rain Harvesting WDDP02 is a reliable, low-maintenance solution that protects your water quality from the source. Model Number: WDDP02.
Please Note: This product is intended for outdoor installation as part of a downpipe and rainwater collection system.
