Backflow Prevention Devices
Is your backflow device due for its annual inspection and certification?
Backflow devices must be fitted on:
- Fire hose reels
- Irrigation systems connected to mains water supply
- Underground water tanks that have mains water backup
- Commercial or industrial machinery connected to mains water supply
If Queensland legislation requires your property to be fitted with a backflow protection device, you are also required to use a licensed plumber with backflow prevention endorsement on their licence for mandatory testing – which must be conducted annually – or repairs.
Kleen Plumbing can install backflow devices and also help you satisfy requirements for backflow testing and certification, which needs to be undertaken every 12 months. This includes replacing backflow valves as required and submitting the required Test and Maintenance Report for local government certification.
To avoid ever forgetting about your backflow testing obligations, Kleen Plumbing can also set you up in an annual follow up program to ensure you never miss your certification deadline or receive any fines as a result.

What is Backflow?
Water systems are designed so that water flows under pressure to and from properties.
Backflow is essentially when water flows in the wrong direction, being drawn back into the system, due to pressure not being maintained. It can occur due to a break in the mains, water being pumped from the mains supply for firefighting purposes, the water outlet on a property being higher than the mains or a variety of other reasons.
When the pressure drops, it creates a vacuum, which has the risk of allowing liquid from a contaminated source to enter the drinking water supply. Depending on the system, this has potential to prove harmful or even fatal for you or your neighbours.
Backflow Prevention Device Installation
Kleen Plumbing’s licensed plumbers are trained and qualified to determine your property’s hazard rating – low, medium or high – and install an appropriate backflow prevention device.
A non-testable backflow prevention containment is satisfactory for low-hazard properties, however a medium-hazard property required a testable double-check valve assembly and a high-hazard property must have a registered break tank, reduced pressure zone or registered air gap installed.
Backflow Testing and Repairs
Kleen Plumbing’s testing of backflow devices using calibrated equipment is always conducted in a timely manner, with all necessary paperwork forwarded to your council for certification purposes.
Any necessary repairs or replacement of a device to meet certification requirements can also be handled.
