Apache Junction Water District requires approved backflow assemblies to be tested at least once a year, at the owner's expense, and failing to test can lead to termination of water service. Some addresses are on Arizona Water Company instead. For a test, repair or replacement, call the number on this page to be connected with a local plumber in Apache Junction.

Local conditions in Apache Junction
Apache Junction has two water utilities, and the provider depends on location. The City's Water Resources page has a Find My Provider map. Homes on the Apache Junction Water District fall under its backflow and cross-connection program, which requires approved backflow prevention assemblies and tests at least yearly, or more often if the manufacturer recommends it. The owner pays for tests, repairs and replacements. The District sends a notice 45 days before a test is due, and failure to test can end with water service being shut off. The District's number is 480-982-6030.
For homes on Arizona Water Company, call that utility at 480-982-2201 about its requirements; its program details weren't found in the research behind this page.
The District classifies its blended water as hard, above 10.5 grains per gallon, and scale is hard on the small parts inside a testable assembly. New installs and replaced valves or pipes need a permit through Development Services, Building Safety and Inspection, on Superstition Boulevard.
Device options at a glance
| Assembly | Typical use | What fails most |

| Reduced pressure | Higher-hazard lines, chemical feeds | Relief valve discharge |
Signs of trouble
- The District's 45-day notice arrived
- A device leaks near the meter along Ironwood Drive or Idaho Road
- A failed result was never repaired
- The body is crusted with scale or cracked
- A new yard or pool line was added off the supply
- Sprinkler zones lost pressure after a valve repair
- A business or HOA landscape meter has assemblies past their date
Timing notes
The 45-day notice gives enough time for a test and, if needed, a repair and retest, so it pays to schedule early in that window. If the notice lists more than one assembly, such as a house line and a separate landscape meter, have them all tested on the same visit and keep the passing reports with your house records. Exposed devices near the Superstition Mountains get full summer sun; a cover protects the rubber parts, and it also helps on the odd freezing winter night.
