For strata managers and body corporate committees across the Illawarra region, ensuring the water supply within a property is safe from contamination is a serious responsibility. Backflow prevention is a key part of this duty, and failing to meet the legal requirements can put residents at risk and lead to compliance issues with local water authorities. In this article, we explain what backflow is, why strata schemes in Wollongong, Kiama and Shellharbour need to stay on top of annual testing, and how Plumbing Creations helps you meet your obligations.
What Is Backflow and Why Does It Matter for Strata Properties?
Backflow occurs when contaminated water is drawn back into a property's main water supply due to inconsistent or low water pressure. In a strata complex, a drop in mains pressure or a sudden increase in pressure within the building can cause water from garden irrigation systems, fire hose reels, or even swimming pools to flow backwards into the drinking water lines. This cross-connection poses a health risk to all residents.
Backflow prevention devices are designed to stop this reverse flow. Common types include double-check valves, reduced pressure zone (RPZ) valves, non-return valves, pressure vacuum breakers, and testable single-check valves. Each device protects against different levels of hazard, and the choice of device depends on the specific fixtures and water uses within the building. For instance, a body corporate with irrigated gardens or a communal pool will typically require a higher degree of protection than a simple residential block with no external water connections.
Understanding the Regulations for Body Corporates
Australian Standards and the National Plumbing and Drainage Code (AS 3500.1) set out the requirements for backflow prevention in all types of buildings. For strata schemes, the relevant water authority — be it Sydney Water or a local council in the Illawarra — mandates that any property with a cross-connection that could contaminate the mains supply must have an appropriately rated backflow prevention device installed.
Annual testing of these devices is a legal requirement and a condition of your water supply connection. This is not optional. For body corporates, failure to arrange and document annual testing can result in the water authority disconnecting supply or issuing fines. The Strata Schemes Management Act also places a duty on the owners corporation to maintain common property, which includes the plumbing systems.
Only fully qualified and licensed plumbers with backflow prevention accreditation are permitted to install, test, and certify these devices. Relying on an unlicensed handyman or an in-house maintenance person is not acceptable under the regulations. Compliance paperwork must be provided to the water authority and kept on file by the body corporate.
The Annual Testing Process for Backflow Devices
Annual backflow prevention testing follows a standard procedure. A licensed backflow plumber visits the strata property, locates every registered device, and performs a series of pressure tests to confirm each valve is working correctly. If a device fails, the plumber will carry out repairs or recommend a replacement. After successful testing, the plumber issues a Certificate of Compliance and a Backflow Prevention Device Inspection and Maintenance Report.
Plumbing Creations offers set pricing and systematic reminders so that body corporates never miss a deadline. We provide the full suite of inspection and reporting paperwork to keep your records in order, and we lodge test results directly with the water authority on your behalf. For strata committees managing a busy calendar, having a single reliable plumber who handles scheduling, testing and lodgement is a major time-saver.
Testing typically takes between 15 and 30 minutes per device, depending on the type and location. For large apartment blocks with multiple devices, we coordinate access to common property areas and ensure minimal disruption to residents.
Choosing a Licensed Backflow Service in the Illawarra
Plumbing Creations provides backflow prevention services as a core part of our strata and commercial plumbing offering, serving body corporates, property managers and landlords in Wollongong, Kiama, Shellharbour and surrounding suburbs. Our licensed team handles installation, annual testing, maintenance, repairs and certification for strata schemes of any size.
By choosing a local plumber familiar with the specific requirements of Illawarra councils and water authorities, body corporates can ensure their compliance paperwork meets the correct standards every time. We hold the required backflow accreditation, lodge test results on your behalf, and send systematic reminders so your strata complex never misses the annual deadline. Keep a copy of every Certificate of Compliance in the building's maintenance log — we provide PDFs you can drop straight into your strata records.
Regular maintenance of backflow prevention devices also extends their lifespan. A device that is tested annually is less likely to fail unexpectedly, which saves the body corporate from costly emergency call-outs and potential water contamination incidents. The relatively small cost of an annual test is well worth the peace of mind it provides for residents and committee members alike.

Frequently Asked Questions
Does every strata scheme in the Illawarra legally need a backflow prevention device?
Not all properties require backflow devices by default. The requirement depends on whether the building has cross-connections that could contaminate the mains supply, such as irrigation systems, fire services, or swimming pools. Plumbing Creations can assess your strata property and advise which devices are needed to meet AS 3500.1 and water authority rules.
Who can legally test backflow prevention devices in NSW?
Only fully qualified and licensed plumbers who hold specific backflow prevention accreditation are permitted to install, test, and certify backflow devices in New South Wales. Plumbing Creations holds the required accreditation, so all testing is performed correctly and the compliance paperwork is accepted by the water authority.
What happens if a backflow device fails its annual test?
If a device fails, we typically carry out repairs on the spot or recommend a replacement. After the repair or replacement, the device is re-tested and a new certificate issued. The old certificate is no longer valid, and the water authority is notified of the outcome.
How often do backflow prevention devices need to be tested?
Backflow prevention devices must be tested annually as a legal requirement and a condition of the water supply connection. Some devices in higher-hazard situations may need more frequent testing, but the standard interval for most strata schemes is once every twelve months.
