Description & Specs

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.

Brilliant Aussie deal

Been buying Rain gear for years and this is one of their better ones. The Rain Harvesting quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.

Worth every cent

Did a lot of comparison shopping before buying here and I have no regrets. Best price I found anywhere and delivery was fast — 3 days to Melbourne. Product feels genuinely premium, not cheap at all. Packaging was solid too, box arrived in perfect shape. Will be back for more.
