Backflow prevention for your rainwater tank overflow. The Air Gap prevents stormwater backflow from entering a rainwater tank, by creating a physical air break on the outlet of the tank overflow and before the stormwater drainage system. The Air Gap also acts as a visual inspection point to detect trickle top-up system failure.
