Backflow Prevention & Testing

Backflow occurs when water flows in the opposite direction through your pipes — potentially allowing contaminated water from your property to enter the mains water supply. This can pose a serious health risk and is why backflow prevention devices are legally required for many commercial, industrial, and residential sites.

At Mackie Plumbing and Gas, we are licensed backflow prevention testers with extensive experience across all property types. Whether you’re installing a new device, need annual testing, or require urgent repairs, we ensure your system remains fully compliant with Water Corporation regulations and Australian Standards.
