Avondale utility backflow testing requirements
Avondale is a strong utility-first page because the city pairs annual testing, approved testers, and specific approved device classes in one public workflow.
Fast answer
Who, when, and what device?
Avondale says annual testing is required, that customers will be notified when results are due, and that only a Certified Backflow Prevention Assembly Tester approved by the City may test devices in the system.
- Who is affected
- Avondale water customers with required assemblies, especially commercial, multifamily, irrigation, and fire-protection services tied to city water.
- Covered devices
- Double check assemblies · Reduced pressure devices · Reduced pressure detector assemblies · Air gap assemblies
- Risk if missed
- Avondale refuses submission of test reports from companies that fail to maintain the required documentation and uses recognized testers for fire-protection and other protected services.

Local detail
Property, device, and enforcement notes
Open the parts that match the property and system. These details stay subordinate to the fast workflow above.
Program and failure notes
- Avondale publishes an approved tester list and annual-notice language.
- Public Works manages both filing and next-year scheduling.
- Fire protection water connections are explicitly regulated.
- Only a certified tester approved by the City of Avondale may test devices in the system.
- Public Works staff file the test results and create the following year's schedule.
- The city can refuse reports from testing companies that do not keep their documentation current.
Residential notes
- Single-family homes are not the main angle because Avondale's strongest public language sits around broader developments and protected services.
- Residential irrigation still matters when the city has required an assembly and annual testing.
Commercial notes
- Commercial intent is strong because Avondale explicitly says all developments except single-family residential require devices.
- The approved tester list and city notification flow make this a real next-action utility page.
Irrigation
Avondale's public rules fit irrigation because the city frames backpressure, chemical injectors, and cross-connections as drinking-water risks that require approved devices.
- Annual testing applies once the device is installed.
- Approved device classes are listed in the city manual.
- The city-approved tester list gives irrigation customers a direct next action.
Fire line
Avondale explicitly requires a double check valve assembly at all fire protection water connections.
- Fire protection water connections are named directly in the engineering manual.
- Certified testers recognized by Avondale must handle the annual and initial testing.
- Device location and installation rules are spelled out in city standards.
Cost and fee context
Testing is market-priced, but Avondale narrows the provider path through its approved tester list.
Repair and retest cost rises on fire-protection and larger commercial assemblies.
The strongest local cost signal is staying inside the recognized-tester workflow so the city accepts the test.
