What is the difference between Promax & Xpress Water Tanks?

The major difference between the Promax & Xpress Water Tanks is the Promax range has corrugated sides, and the Xpress range have smooth sides.

  • The corrugated profile adds a lot of strength to the sidewall of the tank.
  • The Promax 10000, 25000 & 30000L tanks can be buried up to 1m into the ground and be backfilled against if needed.
  • Promax Tanks are available in 7 x colours.
  • Xpress Tanks are available in 2 x colours.
  • Xpress & Promax Tanks have the same warranties.
