Backflow MasterClass #4: Standards, tools and troubleshooting (Learn Live)

• Is WaterMark needed on backflow preventers and why? Many plumbing and drainage products must carry a WaterMark certification to ensure compliance when installed in Australia to demonstrate they comply with the relevant product standards, but what does this really mean and what happens behind the scenes to issue WaterMark? These questions will be explored throughout this presentations. • Drainage sizing for backflow preventers that release water Some backflow prevention devices discharge water during normal operation or failure conditions, requiring correctly sized drainage to handle the maximum possible discharge rate to prevent flooding or property damage. This presentation will discuss roper drainage sizing to ensure compliance and maintains safe operation of the device. • Rainwater storage and backflow Rainwater storage systems must be protected from cross connection risks when connected to a potable water supply, especially when using automatic top up arrangements. Backflow prevention devices are required to ensure treated drinking water cannot be contaminated by rainwater, which may contain debris or microorganisms. Correct system design ensures both water sources remain safe and compliant with regulatory requirements. If you need assistance accessing the class, please contact: troberts@iccsafe.org
