What affects the price?
- Device type — a simple residential PVB is the $89 test; large commercial RPZ assemblies take longer.
- Accessibility — a device buried behind landscaping costs more in labor than one with clear access.
- Repairs — if a check valve fails, parts + labor typically run $120–$350. We'll always quote before touching a wrench.
- How many devices — second and third devices on the same visit are $65 each.
How to avoid overpaying
- Get the flat rate in writing before the visit — not "starting at" pricing that doubles on arrival.
- Ask whether city filing is included. Some companies charge extra for the 10-day report.
- Be wary of anyone who "finds" a failure on every visit. A reputable tester shows you the gauge readings.
One pricing trap to know: you may see "$40 backflow test" ads online — these are typically stale listings or bait pricing that excludes the city filing and adds trip fees. The honest Phoenix market rate for a complete test with filing is $70–$150.
