What is a Backflow Prevention Device?

It’s a device that prevents a contaminated source entering your potable (drinking) water supply. How does this happen?

Backflow occurs when water pressures change from you house to the water main resulting in drawing in of non-potable sources which might be harmful.


Common Systems which require a Backflow Prevention Device installed

  • Underground water tanks that have mains water backups
  • Water outlets in close proximality to chemicals or grease traps. Typically, in commercial buildings, restaurants or hospitals.
  • Fire Hydrants or Hose Reels
  • Irrigation Systems


Important: it’s a Council Requirement that backflow devices are tested and commissioned by a licensed plumber who hold this endorsement. And conducted every 12 months.
