Backflow Preventer for Commercial Property
Same-day Service Available

Need backflow prevention, testing or installation?

Contaminated water can pose serious health risks, disrupt your business operations, and lead to hefty fines. That’s why backflow prevention is crucial for businesses, industries, and properties across Sydney. A properly installed and regularly maintained backflow prevention system is a barrier, ensuring that contaminated water never reaches your clean water supply. This protects your family, employees, and customers from potential health risks, minimises the chance of expensive plumbing repairs, and helps you avoid costly fines for non-compliance with regulations.

What is a backflow preventer test?

A backflow preventer test is a vital safety measure that ensures your backflow prevention device is functioning correctly and preventing contaminated water from entering your clean water supply. Here’s what a backflow preventer test involves:

  • Certified Tester: A qualified and certified plumber inspects your backflow preventer device.
  • Thorough Inspection: The tester checks for any signs of damage, wear, or malfunction.
  • Pressure Testing: A specialised process is used to simulate pressure changes and ensure the device can effectively prevent backflow.
  • Report and Certification: You’ll receive a detailed report documenting the test results and confirming your backflow prevention system’s compliance with industry standards.

Our Methods of Backflow Prevention

We utilise a variety of backflow prevention methods to ensure the safety of your water supply, including:

  • Double Check Valve Assemblies (DCVA): Commonly used for residential and commercial applications, these devices use two check valves to prevent backflow.

  • Reduced Pressure Zone (RPZ): Designed for higher-risk situations, RPZs utilise a pressure-reducing valve to create a lower pressure zone, preventing backflow.
  • Atmospheric Vacuum Breakers (AVB): Suitable for applications where there’s a potential for back siphonage, AVBs use atmospheric pressure to prevent backflow.
  • Pressure Vacuum Breakers (PVB): Similar to AVBs but designed for higher pressures, PVBs are often used in industrial settings.
  • Air Gap Separation: This method involves creating a physical separation between the potable water supply and a potential source of contamination, such as a drain or a tank.

What is the Australian Standard for Backflow Prevention?

The Australian Standard for Backflow Prevention is AS/NZS 3500.1:2018 Plumbing and Drainage Part 1: Water Services. This national standard outlines the requirements for backflow prevention devices and procedures within plumbing systems. Its primary goal is to safeguard the safety and quality of drinking water supplies across Australia.

Frequently Asked Questions

While backflow prevention is crucial for a wide range of properties and businesses, certain industries and facilities face a higher risk of contamination and are legally required to have regular backflow testing.

Here are some examples of facilities that typically need backflow prevention testing:

  • Food Service Establishments: Restaurants, food processing plants, and catering businesses.
  • Healthcare Facilities: Hospitals, clinics, and nursing homes.
  • Water Treatment Plants: Facilities responsible for supplying clean water to communities.
  • Irrigation Systems: Systems used for watering lawns, gardens, and agricultural fields.
  • Industrial Facilities: Manufacturing plants, chemical processing facilities, and other industries that handle hazardous materials.
  • High-Rise Buildings: Buildings with multiple floors and complex plumbing systems.
  • Commercial Properties: Office buildings, retail stores, and other commercial spaces.

Even if your property or business isn’t on this list, it’s still crucial to understand the risks of backflow contamination. If you have any concerns about the potential for contaminated water entering your system, it’s always best to contact a certified plumber for an assessment and advice.

The type of backflow device required for your property depends on its hazard rating, which measures the potential risk of contamination to Sydney Water’s supply system. A qualified, accredited backflow plumber will assess your property’s hazard rating, ensuring you have the appropriate device installed.

Low Hazard Properties:

  • Non-Testable Backflow Prevention Containment Device: Properties with a low hazard rating typically require a simple backflow prevention device, often incorporated within a 20mm or 25mm water meter.
  • Separate Device Installation: If you have a larger meter, an unmetered water connection, or a high or medium hazard rating, a separate backflow device is required.

Medium Hazard Properties:

  • Testable Double-Check Valve Assembly: Properties with a medium hazard rating must have a testable double-check valve assembly installed. This type of device is designed to prevent backflow and can be inspected to ensure it’s functioning correctly.

High Hazard Properties:

  • Registered Break Tank, Reduced Pressure Zone (RPZ), or Registered Air Gap: Properties with a high hazard rating require a more sophisticated backflow prevention device. These options offer greater protection against backflow and are subject to stricter regulations.

Specific Applications:

  • Metered Standpipes: If you have a metered standpipe, it must incorporate a testable double check valve for backflow prevention.
  • Construction Sites: Backflow prevention devices are mandatory for water main connections used in construction and renovation. Single standalone houses are considered low-hazard, while larger projects are classified as high-hazard.
  • Sprinkler and Fire Services: Properties with separate sprinkler and fire services must have a testable double-check detector assembly installed near the water service entry point. Window or wall drencher systems require a non-testable low-hazard device.

Unknown Hazard Rating:

If you’re unsure of your property’s hazard rating, Sydney Water will assume it’s a high hazard. You must install a registered break tank, reduced pressure zone, or registered air gap.
