Rain Harvesting’s 90mm First Flush Diverter with Max Chamber Upgrade Kit (WDDP21) is a next generation first flush that can divert more contaminants and gives greater control over whether to harvest higher quality water or increase water storage volume. Includes the Advanced Release Valve (WDRV01).

Features and Benefits
- Diverts water containing particles of organic and inorganic matter into collection chambers installed on each downpipe.
- Patented First Flush Plus tee prevents dirty water “skipping” over the traditional T-junction gap during heavy rainfall.
- Customisable Diverter Chamber pipe length.
- Transparent, Rapid Release Exit Funnel allows for easy visual inspection and draws sediment into the exit flow for reduced build up and blockages.
- Advanced Release Valve allows you to program how frequently the first flush chamber empties and reduces maintenance.
Keep More Contaminants Out
The First Flush Advanced is more effective at diverting contaminated water. Its patent-pending high-flow inlet largely solves the problem of fast-moving dirty water “skipping” over or around the diverter entrance on traditional T-junction first flush diverters.
Integrated Ball and Seat
This unique design ensure that the first flush ball remains close to the seat, even in high flow events, ensuring the diverter seals as soon as the chamber is full. No more lost balls when cleaning your outlet either!
Maintain With Ease
Maintaining your First Flush Advanced couldn’t be easier. The transparent exit funnel allows for easy visual inspection, while the funnel’s tapered shape draws sediment into the exit flow to reduce build-up and blockages. You can also use the rapid-exit valve to fully empty the diverter as required.
Why Use First Flush Diverters?
Using a first flush diverter improves water quality and reduce tank maintenance by preventing the first flush of water, which may contain roof contaminants (such as sediment, bird droppings, spiders, insects, mosquito eggs and debris), from entering the tank. They help ensure cleaner water is available for use, which protects rainwater pumps and internal appliances.
