Common Questions

How much does backflow testing cost in Auckland?

Typical Auckland pricing: $150–$300 per device for annual testing and certification. Get a written line-item quote before work starts, and compare it against our published price guide — if a quote is far outside the range, get a second opinion.

Do I need a licensed tradesperson for backflow testing?

Most plumbing, gasfitting and drainlaying work in New Zealand legally requires a tradesperson licensed with the Plumbers, Gasfitters and Drainlayers Board (PGDB). Every provider in this directory is checked against the PGDB public register before listing. Gasfitting work additionally requires a gas certificate on completion.

How do I compare backflow testing quotes?

Ask each provider for the same three numbers: hourly rate, estimated hours, and materials/callout fees — not one lump sum. Confirm GST is included. Two or three comparable quotes against our published range tells you immediately who's fair.
