Did you know that many backflow prevention devices in Western Australia are legally required to be tested every 12 months?
A backflow prevention device protects the public water supply from contamination caused by back-siphonage or back-pressure. Without a properly functioning device, chemicals, irrigation water, fire systems, greywater, or other contaminants can potentially flow back into the drinking water network.
✅ In WA, testable backflow prevention devices must be tested at intervals not exceeding 12 months by a licensed plumber with the appropriate backflow testing accreditation.
✅ Property owners are responsible for ensuring their devices are maintained, tested, and compliant.
✅ Test results must be submitted to Water Corporation as part of the compliance process.
Annual testing helps ensure your device is operating correctly, protects public health, and keeps your property compliant with WA regulations.
If you’ve received a reminder notice or can’t remember when your device was last tested, now is the perfect time to book your annual inspection with our qualified team.
