The Tankvac water cleaning system is a marvellous example of Kiwi ingenuity.

Tankvac cleans out your water tank whether plastic, fibreglass, wooden, steel or concrete, using negative pressure and needs no maintenance - it's set and forget technology.

If you have a small micron water filter inline to your house then the life of your filter will be extended considerably.

Main Features:

  • Uses no power, great for off-grid and remote locations.
  • Only flushes when the tank is full, therefore it uses excess or overflow water unlike first flush diverters.
  • Sucks up water from the bottom of your tank taking with it silt, organic material (food for microbes) and stale water.
  • Re-oxygenates the water so it gets its sparkle back.

Tankvac is very efficient, very cost effective and best of all is a one-off expense.

Photos below show the system working. (In normal use, overflow water would be diverted away from the tank.)
