Frequently bought together

The Rain Harvesting 90mm air gap is a UPVC tank fitting that protects your stored rainwater by directing stormwater backflow away from the tank.

  • Size: 90mm
  • Material: UPVC
  • Colour: White
  • Type: Air gap
  • Model: TAAG01

In a rainwater harvesting system, the air gap creates a physical break so that if the stormwater network backs up or floods during heavy rain, that water is directed away rather than flowing back into the tank. This is exactly why water comes out the air gap during a backflow event, and it keeps the tank supply cleaner. It suits new tank installs and upgrades to existing inlets.
