Rainwater Tank Installation Guide

  • The tank site must be flat and level, the area well compacted and free from any rocks, stones and sharp objects.
  • Ensure that the prepared site is at least 600mm larger in diameter than the tank.
  • A 75mm (3”) base of compacted crusher dust may be used as a tank pad. A reinforced concrete slab is also acceptable and must be greater than the diameter of the tank.
  • If a material other than concrete is used, a retaining wall or surround must be provided to prevent erosion.
  • The overflow must be piped well clear of the tank to avoid undermining of the tank base.
  • Ensure that a flexible hose of at least 300mm (12”) is installed after the outlet valve to absorb any shocks or movement.

* Note:- failure to properly install tank as per instructions will void warranty
