Backflow Prevention Melbourne – Installation, Annual Testing & Repairs
Need backflow prevention in Melbourne? Better Plumbing Solutions & Gas Fitting provides professional backflow installation, annual backflow testing, repairs and maintenance for commercial, industrial and residential properties across Melbourne.
Backflow prevention is an important part of protecting Melbourne’s drinking water supply. A correctly selected, installed and maintained backflow prevention device helps stop contaminated or non-drinking water from flowing back into the drinking water network.
Whether you need a new backflow prevention device installed, an annual backflow test completed, a failed device repaired or your property brought into compliance, our experienced plumbing team can help.
What is backflow prevention?
Backflow occurs when water flows in the wrong direction through a property’s plumbing system and potentially enters the drinking water supply.
Under certain conditions, such as a drop in water pressure, a burst water main, high water demand or increased pressure within a private plumbing system, contaminated water can potentially be drawn back towards the water supply network.
Contaminants can come from a range of sources, including chemicals, irrigation systems, industrial processes, equipment, swimming pools and other plumbing installations.
A backflow prevention device is designed to prevent this unwanted reverse flow and help protect the public drinking water supply.
South East Water states that all water service connections need appropriate containment backflow protection, with higher-risk properties subject to additional testing and registration requirements.
Backflow prevention services Melbourne
At Better Plumbing Solutions & Gas Fitting, we provide a complete range of backflow services in Melbourne, including:
Backflow prevention device installation
If your property requires a new backflow prevention device, we can inspect the existing plumbing arrangement, determine the appropriate installation requirements and install the device correctly.
Backflow devices may be required for properties with medium or high-risk plumbing hazards, including many commercial and industrial premises.
The type of device required depends on the level of risk associated with the property and its plumbing system.
Common backflow prevention devices include:
- Reduced Pressure Zone Devices (RPZ/RPZD)
- Double Check Valves
- Testable backflow prevention devices
- Single check valves for applicable fire services
- Registered air gaps
- Break tanks
The appropriate device should be selected according to the property’s risk classification and the requirements of the relevant water corporation.
Greater Western Water also states that medium- and high-risk properties may require backflow prevention devices and that installation should be completed by a licensed plumber accredited in backflow prevention.
Annual backflow testing Melbourne
If your property has a testable backflow prevention device, annual backflow testing may be required.
Regular testing confirms that the device is operating correctly and continues to provide the required level of protection.
For properties within the relevant water corporation areas, testing and reporting requirements apply to registered devices.
South East Water states that devices at medium- and high-risk properties need to be tested at least annually by a licensed plumber endorsed for backflow prevention testing.
Greater Western Water likewise requires owners to arrange annual testing of applicable backflow prevention devices and submission of the completed inspection and maintenance information.
What happens during a backflow test?
During a backflow test, our plumber checks the operation and condition of the device using appropriate testing equipment.
Depending on the device, testing can include checking:
- Operating pressures
- Check valve performance
- Relief valve operation
- Differential pressure
- Device condition
- Isolation valves
- Installation and accessibility
- Compliance with applicable requirements
The results are documented and the relevant backflow test report can be completed for submission to the applicable water corporation.
Backflow repairs Melbourne
A backflow prevention device can fail its test for a number of reasons.
Common issues can include:
- Worn internal components
- Damaged seals
- Debris inside the device
- Faulty check valves
- Relief valve problems
- Corrosion
- Damaged isolation valves
- Incorrect installation
- Lack of servicing or maintenance
If your backflow device fails its annual test, don’t ignore it.
We can inspect the device, identify the problem and carry out the required backflow repairs or maintenance where possible.
In some circumstances, a device may be beyond economical repair or unsuitable for the property’s current requirements. In these cases, replacement may be recommended.
Backflow compliance Melbourne
Backflow compliance is particularly important for commercial and industrial properties.
Depending on the property and hazard level, backflow prevention requirements may apply to:
- Commercial buildings
- Industrial premises
- Factories
- Restaurants and food businesses
- Medical facilities
- Schools and childcare facilities
- Aged care facilities
- Warehouses
- Workshops
- Irrigation systems
- Properties with specialised plumbing equipment
- Fire services
- Properties using chemicals or other potential contaminants
The relevant requirements can vary depending on the water corporation servicing the property.
Melbourne water corporations and backflow
Melbourne properties are serviced by different water corporations, including:
South East Water
South East Water requires appropriate backflow containment protection and has annual testing requirements for applicable medium- and high-risk properties.
Yarra Valley Water
Properties within the Yarra Valley Water service area may have backflow prevention and testing obligations depending on the property’s risk classification and installed devices.
Greater Western Water
Greater Western Water requires applicable backflow prevention devices to be installed, tested and maintained, with annual testing requirements applying to relevant devices.
The three Melbourne water corporations also operate dedicated backflow management systems to help protect the drinking water network.
Fire service backflow testing Melbourne
Backflow prevention can also apply to fire services.
Fire services can present different backflow risks depending on the system design, connections and potential contaminants.
Testable fire service backflow devices need to be maintained and tested where required.
Our team can assist with fire service backflow testing, including testing of applicable single check and other testable devices.
If your property has both a main water service and a fire service, both systems may have backflow prevention requirements.
Who needs backflow testing?
Backflow testing can be relevant to many types of properties across Melbourne.
You may need regular testing if you own or manage:
- A commercial property
- An industrial property
- A factory or warehouse
- A restaurant or food premises
- A medical facility
- A childcare centre or school
- An aged care facility
- A property with irrigation
- A property with specialised equipment
- A property with a fire service
- A property with an RPZ/RPZD
- A property with another testable backflow prevention device
If you’re unsure whether your device needs testing, a qualified backflow plumber can inspect the installation and advise you on the applicable requirements.
What if my backflow device fails?
If your backflow prevention device fails its annual test, it should be addressed promptly.
The first step is to determine why the device failed.
Depending on the problem, the solution may involve:
- Cleaning the device
- Servicing internal components
- Replacing damaged components
- Repairing valves or fittings
- Correcting installation issues
- Re-testing the device
- Replacing the entire backflow prevention device
The aim is to restore the device so it provides the required protection and meets the applicable requirements.
