Understanding AS/NZ 3547: Ensuring Backflow Prevention and Water Safety in New Zealand

In New Zealand, water safety is a top priority for both residential and commercial plumbing systems. One of the key standards governing this safety is AS/NZ 3547, which outlines the performance requirements for backflow prevention devices. Compliance with this standard is essential for protecting public water supplies from contamination. For those seeking reliable and compliant backflow prevention systems, the Prodigy backflow prevention valve from ADT is a trusted solution.

What is AS/NZ 3547?

AS/NZ 3547 is the joint Australian/New Zealand standard that specifies the functional requirements and testing methods for backflow prevention devices. These devices are crucial for stopping the reverse flow of potentially contaminated water into clean potable water systems.

Backflow can occur due to a drop in water pressure or other system anomalies. Without proper prevention, contaminants such as chemicals, bacteria, or waste materials can infiltrate the public water supply—posing serious health risks.

AS/NZ 3547 ensures that all approved devices meet rigorous performance, durability, and safety benchmarks before being installed in any system.

Key Requirements of AS/NZ 3547

• Rigorous Testing
  Devices must undergo hydraulic testing for performance, durability, and leakage under specified pressure conditions.

• Design Compliance
  Backflow preventers must be designed to allow maintenance and testing while in place, and they should be tamper-resistant to prevent unauthorized access.

• Material Safety
  All materials used in these devices must be safe for potable water and resistant to corrosion or chemical degradation.

• Certification & Labelling
  Only certified products bearing the appropriate markings and approvals can be used under this standard.
