Backflow Prevention Plumbers

Backflow Prevention Testing & Installation
Without properly installed and maintained backflow prevention devices, contaminated water can flow backwards into the mains and pose a serious risk to public health. At Newflo Plumbing, we provide licensed backflow prevention installation, testing and annual compliance services for residential and commercial properties across Geelong and the Bellarine Peninsula.
What Is Backflow Prevention?
Backflow occurs when water flows in the opposite direction to its normal path — moving from a property's internal plumbing back into the public drinking water supply. This can happen due to a sudden drop in mains pressure (back-siphonage) or when internal water pressure exceeds the mains supply pressure (back-pressure). Either way, the result can be contamination of the public water network with chemicals, bacteria or other harmful substances.
A backflow prevention device is a mechanical valve installed on your water supply line that stops this reverse flow from occurring. These devices are a regulatory requirement for many property types in Victoria, and must be installed, tested and maintained by a licensed and registered backflow prevention tester.
All backflow testing carried out by plumbers holding a current Backflow Prevention Endorsement.
We test, certify and lodge results with Barwon Water on your behalf — no deadlines to chase.
Supply, install and repair all device types to AS/NZS 3500 standards and water authority requirements.
Who Needs a Backflow Prevention Device?
The requirement is determined by your water authority based on the hazard level of your property type and water connections. Common scenarios include:
Businesses using chemicals, fertilisers, cleaning products or any substance that could contaminate the water supply — including cafés, restaurants, laundries, medical facilities, car washes and manufacturing premises.
Garden irrigation systems present a genuine backflow risk, as fertilisers and pesticides can be drawn back into the water supply. Many councils and water authorities now require backflow devices on in-ground irrigation systems.
Any property where a hose or fill point is submerged in water — including pools, spas and water features — requires an appropriate backflow prevention device on the supply connection.
Properties with fire suppression systems, hydrant boosters or sprinkler systems are required to have testable backflow prevention devices installed due to the chemicals often present in the water.
While many homes don't require a testable containment device, properties with irrigation, pools or any connection that presents contamination risk may trigger the requirement. We can assess and advise.

Annual Testing & Certification
In Victoria, testable backflow prevention devices must be tested annually by a licensed tester and results reported to your local water authority. We carry out testing, provide certification documentation and lodge results with Barwon Water on your behalf — so you never have to worry about keeping on top of deadlines.

Backflow Device Repairs
Over time, backflow prevention devices can fail, corrode or become fouled, reducing their effectiveness. If your device fails its annual test, we carry out repairs or replacement promptly to restore compliance and protect your water supply.

Hazard Assessments
Not sure whether your property requires a backflow device, or what type is needed? We carry out professional hazard assessments to evaluate your property's risk level and provide clear, honest advice on the most appropriate solution.
Backflow Prevention Compliance in Victoria
In Victoria, the installation and testing of backflow prevention devices is governed by the Plumbing Regulations 2018, AS/NZS 3500, and the requirements of individual water authorities — including Barwon Water, which covers the Geelong and Bellarine Peninsula region.
Properties required to have testable backflow prevention devices must arrange annual testing by a licensed plumber who holds a current Backflow Prevention Endorsement. All test results must be submitted to Barwon Water, and failure to maintain compliance can result in notices and penalties from the water authority.
Newflo Plumbing holds the necessary licences and endorsements to carry out all aspects of backflow prevention work in the Geelong region. We manage the compliance reporting process on behalf of our customers — from annual test scheduling through to lodging results with Barwon Water — so your obligations are always met without the administrative burden.
Frequently Asked Questions
The requirement is typically determined by your water authority based on the hazard level associated with your property type and the nature of your water connections. If you've received a notice from Barwon Water, or if your property has an irrigation system, pool, spa or commercial water connection, it's worth contacting us for an assessment. We'll give you a clear, honest answer at no obligation.
Testable backflow prevention devices in Victoria must be tested annually. We keep records of your device and can send reminders when your next test is due, making it easy to stay on top of your compliance obligations.
If your device fails its annual test, it must be repaired or replaced before results are submitted to the water authority. We carry out same-visit or prompt follow-up repairs in most cases, minimising any delay to your compliance certification.
No. Under Victorian law, the installation of backflow prevention devices must be carried out by a licensed plumber. Testing of testable devices must be performed by a licensed plumber who holds a current Backflow Prevention Endorsement. Attempting to install or test a device without the appropriate licence is illegal and could void your insurance.
The type of device required depends on the hazard level of the connection. Common types include atmospheric vacuum breakers (suitable for low-hazard connections such as garden taps), double check valves (medium hazard, such as irrigation systems), and reduced pressure zone (RPZ) devices (high hazard, such as chemical dosing systems or fire services). We'll advise on the correct type for your specific situation.
