First Flush Advanced Downpipe Kit WDDP120 4" advanced release valve from Rain Harvesting Pty by Blue Mountain Co.

The WDDP120 4" First Flush Advanced Downpipe Kit includes patented first flush plus tee and advanced release valve. First Flush Advanced protects your rainwater quality by diverting the first flush of the most contaminated water from your roof away from your rainwater tank. 

Keep More Contaminants Out:   
The First Flush Advanced is more effective at diverting contaminated water. Its patented 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.

Control Quality and Volume:
With its electronic advanced release valve, the First Flush Advanced gives you greater control over how frequently you release your diverted water. Increase your release frequency to maximize water quality or release the dirty water less frequently to maximize stored water volumes.

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.
