What is backflow prevention?

Backflow prevention is the term used to refer to the prevention of an unwanted, reverse flow of water from a potentially polluted or contaminated source back into the clean drinking water supply pipework.

Testable backflow prevention devices shall be commissioned and tested after installation and prior to service. They shall be maintained in working order and be tested for operational function at intervals not exceeding 12 months.

Backflow prevention devices are essentially installed to prevent the possibility of back-siphonage and or back pressure from potential contaminated sources.

Examples of potential sources of contamination:
● Fire Hose Reels (FHRs)
● Irrigation systems
● Swimming pools
● Vehicle maintenance pits
● Ornamental ponds
● Air conditioning towers
● Vehicle/bin washing bays
● Chemical injection areas

Examples of properties requiring backflow prevention:
● Hotels, motels and apartment buildings
● Vehicle workshops, garages and car-washes
● Shops
● Restaurants
● Caravan parks
● Medical and dental facilities
● Dry cleaners and laundries
● Hospitals and funeral parlors
● Sports Clubs
● Schools, day care centers and kindergartens
● Pest control and water carrying vehicles
● Botanic gardens

What is the safeguard to prevent a backflow occurrence?
A correctly selected backflow prevention device (one-way valve) will eliminate any risk of contamination of the drinking water supply. Backflow devices are either testable or non-testable types with the selection dependent on the risk associated with the possible contamination.
Application & registration of backflow prevention devices

Council is required to keep a register as per the following:
● Standard Plumbing and Drainage Regulation 2003 Section 38 – Testable backflow prevention devices,
● State Government Standard Plumbing and Drainage Regulation 2003.

A local government, or an authorized entity, must maintain a register of the testable backflow prevention devices.

An owner of an installed testable backflow prevention device must;
● register the device with the local government or entity; and
● have the device inspected or tested by a person who is licensed to do the work, every 12-months.

The endorsed plumber who tests a backflow prevention device, must within ten business days from inspection, provide written test results to Council.

Here’s what our happy customers have to say about us:


My experience with Sawyer plumbing (Geoff) has been excellent. He is professional, reliable, does an outstanding job at a competitive price. He has done several jobs at my home now (old Queenslander) including re-plumbing the entire house, replacing the toilet and with more to come! My wife and I both have his number saved in our phones and I will always now approach him 1st over competitors. If you need a trustworthy, top quality tradie then I wouldn’t recommend anyone else.

Joshua Thomas

Couldn’t recommend Sawyer plumbing enough ! What a service – reliable – trustworthy and a great job ?? was able to fit my job in on a day’s notice and completed it with absolute perfection- competitive pricing- pure professional- Thanks Geoff !

Muriel Heslop

Finding reliable, professional trades folk, who do quality work in a timely and efficient manner and charge a fair price is something all of us seek. Geoff Sawyer more than met all those requirements. We were very pleased with the job he did of reguttering our house and replacing the down piping, as well as repair work to facia boards and surfeits. We were extremely more than happy with Geoffs work! We unhesitatingly recommend Geoff for any work you might need done!
