Testing and reporting

If you have a testable backflow prevention device installed at the water meter you must have the device tested every 12 months. 

Annual testing ensures that the backflow prevention device continues to operate correctly. A defective device can: 

  • cause a backflow incident 
  • allow water to escape through leaking devices 
  • reduce the water pressure to your property. 

To complete the test, you need to engage an accredited backflow prevention plumber.
