Backflow is the undesirable reverse flow of water within a supply pipe, typically caused by a drop in pressure or a problem with the water mains. When backflow occurs, hazardous substances can potentially mix with the potable water supply, causing contamination and posing a threat to public health.
In Western Australia, it is a legal requirement for backflow prevention devices to be installed on properties with a medium to high risk of drinkable water contamination due to the reverse flow of contaminants or chemicals. These devices play a crucial role in safeguarding the potable water supply and ensuring the safety and well-being of the community.
Backflow prevention devices can be installed in three different areas: at the property boundary (containment protection), around a group of potential hazards (zone protection), and at an individual hazard (individual protection). Once a device is installed and tested at commissioning, it must be serviced every 12 months by a Licensed Plumber qualified in backflow testing. A report is then submitted to the Water Corporation as part of the testing procedure.
Please note that if yearly testing does not occur, property owners may be issued a non-compliance notice from the Water Corporation and risk incurring fines.
