Rain Harvesting 90mm Auto Tank Vac for Concrete Tanks | Automatic Sediment Removal Australia

Sediment buildup on the floor of your rainwater tank is one of the biggest threats to water quality — and the Rain Harvesting 90mm Auto Tank Vac for Concrete Tanks eliminates it automatically, every single time your tank overflows.

Simply attach the Auto Tank Vac to your 90mm overflow outlet and let it do the work. As overflow occurs, the device draws heavy sediment, fine particles, heavy metals and bacteria up from the tank floor and removes them through the overflow pipe — before they can be stirred up and resuspended into your stored water supply.

The result is cleaner water, fewer tank clean-outs and significantly reduced filter cartridge replacement costs over time — making this one of the smartest, most cost-effective upgrades for any concrete tank owner.
