Maintenance

It’s important to ensure that your first flush diverter outlet remains clear of any debris. If your outlet becomes blocked, the chamber will not empty and the first flush of water will not be diverted when it rains.

To ensure the flow of water out through your Slow Release Valve, periodically remove from the Transparent

Rapid Release Exit Funnel to check for any build-up of matter. Remove filters, and clean if required.

For best results and minimal maintenance, rain heads with 0.955mm aperture mesh such as Leaf Eater Rain

Heads must be installed upstream of the First Flush Boost to limit the entry of debris that can reach your diverter.
