Air Gap
Air Gaps prevent stormwater backflow from entering your tank - ensuring your water supply is not contaminated.
If there is a stormwater backup caused be heavy rain or blockages in your local stormwater network, water can flow up your overflow pipes towards your tank. The Air Gap's open mouth is a physical break in the line, which means that this backflow water will flow out of the opening rather than make it to your tank.

Mosquito-proof your tank
Simple Maintenance
Benefits
Prevent Stormwater Contamination
The Air Gap's open mouth creates a physical air break in your tank overflow outlet pipe, which stops stormwater surges from back-flowing into your tank and contaminating your rainwater supply. Importantly, it still allows water to flow through the overflow which ensures your tank is always performing smoothly.
Benefits
Keeps mosquitos out
The dual, mosquito-proof 955 micron (0.955mm) stainless steel screens prevent mosquitos and other pests from entering your rainwater tank.
Benefits
Simple maintenance
Occasional maintenance on your system is inevitable - the Air Gap makes it easy with its easily removable screens.
Benefits
Easy installation
Installing an Air Gap is straightward, and generally just requires a section of pipe to be removed where the Air Gap will sit. It can also be painted to match your system's aesthetic.
