Maintenance IIt’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 diverter’s outlet, periodically check the transparent, rapid release exit funnel for any build-up of matter (Remove primary filter and clean if required). Periodically check that the Electronic Release valve batteries have charge.
