Backflow Prevention in Melbourne: Protecting Your Water Supply
Backflow prevention is an important part of maintaining a safe drinking water supply, particularly for commercial, industrial and other properties where plumbing systems may present a contamination risk.
If water from your property flows backwards into the drinking water network, it can potentially introduce contaminants into the public water supply. A correctly selected, installed and maintained backflow prevention device helps prevent this from happening.
Better Plumbing Solutions provides professional backflow prevention services in Melbourne, including backflow device testing, servicing, repairs, replacement and compliance reporting.
What Is Backflow?
Water normally flows from the drinking water network into your property under pressure. If that pressure changes, water can potentially flow in the opposite direction.
This is known as backflow.
A reduction in water pressure can occur for several reasons, including a water main break, high demand on the network or other changes in pressure.
Backflow can also occur when there is a cross-connection between the drinking water supply and a potentially contaminated source. Examples can include irrigation systems, chemical processes, commercial equipment and other plumbing installations.
Yarra Valley Water explains that backflow can potentially occur when water pressure falls and contaminated water is able to be drawn back into the drinking water network.
Why Is Backflow Prevention Important?
The purpose of backflow prevention is to protect the quality and safety of the drinking water supply.
A property may contain substances or equipment that could present a contamination risk if water were to flow backwards.
Depending on the property, potential hazards can include:
- Chemicals and cleaning products
- Fertilisers
- Irrigation systems
- Industrial fluids
- Food processing equipment
- Commercial machinery
- Recycled water connections
- Swimming pool systems
- Trade or manufacturing processes
The appropriate level of protection depends on the hazard associated with the property and its plumbing system.
Does Your Melbourne Property Need a Backflow Prevention Device?
Not every property requires the same type of backflow protection.
The required device depends on factors including the property’s plumbing configuration and the level of hazard associated with the activities carried out on the site.
For example, Yarra Valley Water identifies high, medium and low hazard levels, with different types of backflow protection applicable depending on the risk.
Commercial and industrial properties can have a higher likelihood of requiring dedicated backflow prevention protection, particularly where plumbing systems connect to processes or equipment that could contaminate the drinking water supply.
If you’re unsure whether your property requires a backflow prevention device, a qualified backflow prevention plumber can assess the site and determine the appropriate protection.
Types of Backflow Prevention Devices
Different devices provide different levels of protection.
Depending on the hazard, a property may require devices such as:
Reduced Pressure Zone Device
A reduced pressure zone device, commonly known as an RPZ, is a testable device generally used where a higher level of backflow protection is required.
Double Check Valve
A double check valve is a testable device that can be used for certain medium-hazard applications.
Dual Check Valve
A dual check valve can provide protection for lower-risk applications where appropriate.
The correct device should be selected according to the assessed hazard rather than simply choosing a device based on the property’s existing plumbing.
Backflow Prevention Testing Melbourne
Installing a backflow device is only part of the process.
Testable backflow prevention devices need ongoing maintenance and testing to ensure they continue to operate correctly.
For example, Yarra Valley Water requires testable backflow prevention devices installed at the water meter to be tested every 12 months, with the results submitted to the water corporation.
South East Water’s current guidance also states that property owners with testable devices are responsible for annual testing and submitting the test report to the relevant water corporation.
What Happens If a Backflow Device Fails?
A failed test doesn’t necessarily mean that the entire backflow prevention device needs to be replaced.
A plumber can inspect the device and determine whether servicing or replacement of components is possible.
Depending on its condition, the device may require:
- Servicing
- Replacement components
- Cleaning
- Repairs
- Complete replacement
- Retesting following repairs
The important thing is to address a failed device promptly rather than leaving the property without appropriate backflow protection.
Backflow Compliance for Melbourne Businesses
For business owners, property managers and facility managers, keeping backflow prevention requirements up to date can be an important part of property maintenance.
Better Plumbing Solutions can assist businesses with:
- Backflow device testing
- Backflow prevention inspections
- Device servicing
- Backflow repairs
- Device replacement
- Testing documentation
- Compliance reporting
- Water authority lodgements
This can help simplify the ongoing management of backflow prevention requirements, particularly for businesses responsible for multiple properties.
Which Melbourne Water Authority Covers Your Property?
Backflow requirements and reporting can depend on which water corporation services your property.
Melbourne properties may fall within areas serviced by water corporations including:
- South East Water
- Yarra Valley Water
- Greater Western Water
The relevant water corporation should be confirmed for the property’s address before arranging compliance work.
Better Plumbing Solutions can assist with the testing and documentation process for properties across Melbourne’s metropolitan area.
Backflow Prevention for Commercial & Industrial Properties
Backflow prevention can be particularly important for businesses where water is used alongside chemicals, machinery, irrigation, manufacturing processes or other potential contaminants.
Industries and properties that may require backflow protection can include:
- Factories
- Warehouses
- Restaurants
- Commercial kitchens
- Medical facilities
- Dental practices
- Schools
- Childcare centres
- Nurseries
- Irrigation sites
- Manufacturing facilities
- Shopping centres
- Apartment developments
Every property is different, so the appropriate backflow protection should be assessed based on the actual plumbing installation and activities taking place on the site.
