Rain Harvesting 90mm Air Gap Backflow Prevention

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.

Features and Benefits

  • Two removable mosquito screens for easy cleaning and low maintenance
  • Each screen is made from mosquito proof stainless steel mesh with 0.955mm aperture
  • Air Gap provides a visual inspection point on overflows
  • Easy to install
  • Easy to paint
  • HB 230 Requirement

Installation Instructions

The Rain Harvesting Air Gap incorporates two 90mm Female sockets that glue directly to DN90mm pipe. Install the Air Gap to a vertical section of pipe after the overflow of the tank. To maximise performance, install the Air Gap a minimum of 300mm below the overflow outlet. Ensure the Air Gap is installed the right way up, NOTE instructions on product: ‘Install this side facing up’. If installing the Air Gap to existing pipe work simply remove a 142mm section of pipe to allow fitment.
