Testing a backflow device

1. Ask us to test it

• Email backflow@water.co.nz or call us on (09) 442 2222. We will bill you for this service.

2. Engage an independently qualified person (IQP) to test it

• To find an IQP, go to the Auckland Council list of IQPs  (IQP= Independently qualified person)

• Click the Systems/Feature dropdown arrow and scroll to SS7. Select SS7 and click Search the Name, Suburb Address or other options to see a list of IQPs who can install or test your device.

• On the search results page, click Expand All for contact details.

When your device passes the test, the tester issues a certificate. They may use their own certificate, or download our boundary backflow device test certificate.

If you use Watercare for testing, we will hold a copy of the certificate and supply this to you if required.

If you use an independent tester, they (or you) will need to email a copy of the certificate to us at backflow@water.co.nz

If we don’t receive a test certificate, we will arrange for your device to be tested, and will bill you.

If your device fails the test or you do not repair it on time, we will contact you stating that it is a high priority to repair it.

If you don’t repair and retest the device within 2 weeks of receiving this message, we will revisit the device, make repairs, and invoice you for this work.

As the owner of a boundary backflow device you must pay for the tests. Independent testers will have their own fee schedule for this work.
