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 lisk 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.
