Annual or event-based timing
Commercial, industrial, irrigation, and fire-line services plus any residential or multifamily property where Phoenix determines that a cross-connection hazard exists.
- Upon installation and annually thereafter
- Phoenix requires certified testers on the city list to perform testing and repairs, and the approved report has to be forwarded to Planning and Development by the due date shown on the work order.
Non-compliance penalties
Phoenix publishes noncompliance penalties inside the tester packet and can hold compliance open until the city-approved report is delivered. Fire-line downstream testing is handled separately by the Fire Department.
- Phoenix ties testing to a city work-order due date.
- Only testers on the city list can perform the accepted test and repair workflow.
- Fire-line downstream testing follows a separate responsibility path.
