You will need to comply with this standard to manufacture backflow prevention devices.
This standard specifies requirements for the materials, design, performance and testing of mechanical backflow prevention devices that are used for the protection of water supplies, for health and safety and protection of the environment.
It prescribes the requirement that you will need to install a backflow prevention device on your property if your property is assessed as a high or medium hazard risk.
- High risk sites use or produce products of a toxic or bacterial nature that may cause death if leaked into the main water supply (e.g. chemical plants and hospitals).
- Medium risk sites can endanger health if backflow occurs (e.g. caravan parks and public swimming pools).
- Low risk sites could result in a nuisance but not endanger health if contamination occurs (e.g. residential homes).
If your property is assessed as needing a device, you must have it installed by a licensed plumber within three months. Your licensed backflow prevention plumber will also complete a Certificate of Compliance and Backflow Prevention Inspection and Maintenance Report.
