Backflow prevention testing is an annual test that is legally required to ensure your properties testable backflow device is fully operational.
City of Gold Coast Mandatory Backflow Prevention Testing
City of Gold Coast will send you an annual reminder letter about having to have all your backflow prevention valves being tested which will look like the letter on the right.
Backflow prevention valves are installed in most commercial properties plus in homes where a potential cross connection can occur in the water supply.
Backflow prevention valves are installed to plumbing fixtures after a risk assessment. They are either testable or non-testable valves based on an assessment of risk of possible cross contamination.
If you have testable valves then the Queensland Government requires City of Gold Coast to maintain a register of all testable devices in the city to protect the city’s water supply from cross-connection contamination.
This is why you will receive a letter requiring annual testing as per AS/NZS 3500.1-2015 Plumbing and Drainage – Water Services under clause 4.4.6 Commissioning and Maintenance: Testable backflow prevention devices shall be commissioned and tested after installation and prior to service. They shall be maintained in working order and tested for operational function at intervals not exceeding 12 months. Reduced pressure zone devices, double check valve assemblies, pressure type vacuum breakers, registered break tanks and registered air gaps shall only be used with a maintenance program for device registration and test certification.
