There has been confusion in the industry about whether a Form 4/4A is required for backflow prevention devices.
A licensee is required to lodge a Form 4/4a if they install, replace or remove a testable backflow prevention device (refer to category 8 of schedule 2, Standard Plumbing and Drainage Regulation 2003).
A licensee is required to lodge a Form 9 with the Local Government Authority (LGA) every time they test a backflow prevention device.
This means, for example, if a licensee replaces then tests a backflow prevention device, they must submit both a Form 4/4A and a Form 9.
Licensees must also ensure they have the appropriate backflow prevention endorsement if they wish to commission, test or maintain backflow prevention devices, or if they wish to supervise any licensees performing this work.
