Arrange backflow testing with confidence
Keep backflow protection under review
Backflow testing helps confirm whether a testable backflow prevention device is still protecting the drinking water supply as intended. For businesses, facilities and industrial sites, the task often sits alongside asset management, access controls and the need to limit disruption to normal operations.
Testable devices have moving parts, seals, springs, check valves, relief valves and test points. Over time, components can wear, become fouled with debris, leak or stop holding pressure correctly. A field test provides a practical check of device performance and can identify whether repair, replacement or further investigation may be needed.
When backflow testing may be required
Backflow testing may be arranged following installation, as part of ongoing device management, or after maintenance, repair or replacement. It can also be relevant when a device is leaking or discharging, when records need updating, or when a site needs a current test report for its own administrative requirements.
In Western Australia, Water Corporation requires boundary containment backflow devices to be registered and tested at commissioning. Subsequent testing is required annually or after maintenance. Water Corporation states that test reports must be submitted through its online lodgement system by an accredited backflow tester permitted to test those devices.
Water Corporation also states that installation, commissioning and repair of backflow prevention devices must be carried out by a licensed plumbing contractor, while accredited backflow testers can test testable devices. Confirm the scope of your particular job with the plumbing business you choose.
What happens during commercial backflow testing
Commercial backflow testing involves inspection and field testing of the device. The tester may record the device condition and readings, assess whether its operation aligns with expected performance, and identify whether servicing, repair, replacement or further investigation is appropriate.
Depending on the device and its condition, related work may involve cleaning strainers or internal components, replacing seals, springs, check valves or relief-valve parts, or investigating a failed test. A failed result does not by itself determine the final solution; the condition of the device and the site circumstances need to be considered.
For commercial backflow prevention testing, ask how test results and any recommended follow-up work will be documented. This supports clearer communication between site contacts, maintenance teams and the plumbing business.
Information that helps a plumbing business prepare
Good information before attendance can help a plumbing business understand the asset, arrange appropriate access and work around operational restrictions. Useful details include:
- the device make, model, size, serial number and asset ID, where available;
- previous test reports, maintenance history and Water Corporation registration details;
- the exact device location, photographs of the valve assembly and any visible labels;
- whether the device is leaking or discharging, and whether water can be isolated;
- site contact details, access instructions, induction requirements and permitted working hours;
- shutdown restrictions, tenant or business continuity considerations, and the person authorised to approve repairs; and
- the report format needed and the reason for the test, such as routine compliance, a fault, water loss, sale or insurance.
For an industrial backflow testing enquiry, also flag relevant safety permits, process impacts, environmental controls, confined-space risks, hot works requirements and critical production impacts. These details help the plumbing business assess the practical conditions before attending.
Testing, repairs and installation are different jobs
| Service | What it addresses |
|---|---|
| Backflow testing | Inspection and field testing to assess whether a testable device is operating as intended. |
| Repairs and maintenance | Attention to worn, leaking, damaged or failed components and devices. |
| Installation | Work associated with fitting and commissioning a backflow prevention device. |
Knowing which outcome you need helps direct the enquiry. If the immediate requirement is a test but the device fails, the plumbing business can discuss the appropriate follow-up work and any site considerations.
Products and equipment you may encounter
Backflow assemblies, components and testing equipment can be associated with a range of brands and supply channels. Examples customers may encounter include Watts, Febco, Zurn, Wilkins, Apollo, RMC, AVG, Bermad, Ames and Enware. Reece, Galvins, Tradelink, Parkwood Plumbing Centre, Bunnings and Plumbing Plus are also among the supply channels associated with backflow products.
Names on an existing device, valve assembly or test equipment can be useful reference details when making an enquiry. They do not, on their own, establish the condition of a device or the work required.
Choose a Master Plumber with the right information
Find a Master Plumber is backed by the Master Plumbers and Gasfitters Association of Western Australia. It connects customers with Master Plumbers and plumbing businesses associated with Master Plumbers WA, helping customers make a more informed choice of plumbing business for a property or project.
For a commercial backflow device testing request, be clear about the device, site and operational constraints rather than relying on a broad description. This gives the plumbing business a more useful starting point for discussing the testing work and any likely follow-up.
If your need extends beyond testing, you can also consider Backflow Repairs and Maintenance or Backflow Installation.
