The course is designed to give trainees both the theoretical and practical skills required to become an IQP (Independently Qualified Person) to test and inspect Backflow Devices. The training is a mix of classroom based theory and hands on practical learning, involving the use of backflow testing kits, in order to learn the correct testing procedures for the various type of backflow prevention devices.
After completing the course people wanting to become an IQP will need to apply directly to the relevant local authority to join their list of registered practitioners. Any questions regarding the requirements to become registered, or about the registration process, should be directed to the relevant local authority as they administer this process. Upon satisfactory completion of the course and gaining the unit standards this application can take place. The course completion certificate will be required as part of this IQP application process. NOTE: you still need to apply directly to the relevant council to get IQP registered with them, this course does NOT give you IQP registration.

Testing and Inspection of Backflow Prevention
There are two NZQA unit standards which can be completed while on the course for those wanting to carry out the testing of backflow devices. These are assessed with both theory and practical testing assessments. Those unit standards are:
NZQA Unit Standard 23847 - Prepare to test, and inspect and test, water supply backflow prevention devices
NZQA Unit Standard 23848 - Describe suitability, installation, and testing of water supply backflow prevention devices, and fault identification
There is a third optional unit standard on the installation of backflow devices which may only be completed by people who hold a current plumbing certificate or licence as issued under the Plumbers, Gasfitters, and Drainlayers Act 2006. This prerequisite is because the unit standard assumes a background plumbing knowledge which this course does not cover. This unit standard is:
NZQA Unit Standard 2117 - Install, test, and maintain water supply backflow prevention devices
This course has no prerequisites to attend and complete the requirements to test backflow devices, but a basic understanding of backflow devices and some basic plumbing knowledge is helpful.
In order to complete the third optional NZQA Unit Standard 2117 - Install, test, and maintain water supply backflow prevention devices, you must hold a current plumbing certificate or licence as issued under the Plumbers, Gasfitters, and Drainlayers Act 2006.
This course is recommended for Plumbers, Council engineers and contractors (installers, regulators and maintenance), Compliance officers, Water treatment operators, Irrigation personnel (designers, installers and maintenance), and anyone wanting to become an IQP to work on backflow devices.
