  • Who is affected: Commercial, industrial, irrigation, and fire-line services plus any residential or multifamily property where Phoenix determines that a cross-connection hazard exists.

Workflow

Phoenix workflow order

  1. Confirm whether Phoenix has identified the service as requiring a backflow assembly.
  2. Use a tester from the city's approved tester list.
  3. Complete the approved report and deliver it by the due date shown on the work order.
  4. Retain the testing records in case Phoenix requests follow-up documentation.
