The City of Avondale's Public Works Cross Connection Control Program covers yearly testing of backflow assemblies, keeps an Approved Backflow Tester List, and takes reports at [email protected]. Parts of Avondale are on Liberty water instead, which has its own rules. For a test or repair, call the number on this page to be connected with a local plumber in Avondale.
Local conditions in Avondale
Most of Avondale gets water from the City's Public Works Department, while Liberty Litchfield Park, part of Liberty Utilities, supplies water and wastewater to some portions of the city. Which one serves you is printed on your bill. City customers fall under the Avondale Cross Connection Control Program. Its FAQ addresses yearly testing of backflow prevention assemblies, the City maintains an Approved Backflow Tester List, and finished reports go to [email protected]. The Backflow Hotline is (623) 333-4405, and it can tell you whether a device at your address is on the City's testing list.
Businesses, apartment complexes and HOA landscape lines are the accounts most likely to carry testable assemblies, but a house with a pool fill, a fertilizer injector or a fire sprinkler line can need one too.
Liberty customers follow Liberty's cross-connection program instead. Where Liberty requires a device at the meter, it must be tested initially and every year by an AWWA certified tester, and a failed unit has to be repaired and retested within 15 days.
Avondale's city water is a blend of groundwater and Colorado River water delivered through the City of Phoenix. New devices or plumbing changes go through Development Services, Building Services Division, at 11465 W. Civic Center Drive.
Repair or replace after a failed test
| Situation | Usual direction |
|---|---|
| Check valve fouled with debris or scale | Clean or rebuild, then retest |
| Relief valve leaking on a reduced pressure unit | Rebuild kit, then retest |
| Cracked body or bonnet | Replace the assembly |
| Parts no longer made for an old model | Replace the assembly |
| Device installed below the heads it protects | Relocate or change the device type |
Signs worth a call
- A test reminder from the City or from Liberty
- Steady dripping from a test cock or relief port
- A failed report with no follow-up
- Irrigation pressure dropped off after a repair
- Commercial or multi-family assemblies past due
Timing and seasons
Book soon after a notice so there is room for a repair and retest. Heat dries out rubber parts on exposed devices through the summer, and a rare freezing night can crack an uncovered body, so check the device when the weather turns.
