Course Overview

This is a QBCC Commissioner Approved online course required for all plumbers who need to renew the backflow endorsement on their plumbing licence. The revalidation is required to be successfully completed every five years in order to maintain the backflow endorsement on your license.

The course covers a review of the current relevant legislation relating to backflow procedures and practices. Specifically, it covers the competency required to test, commission and maintain backflow prevention devices. It covers preparation for the work, the identification of testing and commissioning requirements, the physical testing and commissioning of devices, the maintenance of devices and the completion of work finalisation processes.

To complete the backflow revalidation course, participants will be required to complete a self-paced online assessment and submit six (6) previous test reports tested to the current standard.
