  • Irrigation, pools, and other outdoor hazards can still trigger the same annual documentation problem.
  • Use the utility program page first when a landscaper gives a generic answer.
Workflow

Workflow

  2. Schedule testing with a tester who can submit through the accepted utility path.
  3. If the device fails, repair and retest before treating the file as complete.
Residential

Residential

  • Residential pressure vacuum breakers and irrigation assemblies matter mainly when the utility or irrigation rules require enrollment.
  • Homeowners should confirm whether a pool auto-fill or irrigation setup has already triggered a backflow record with the City.
Commercial focus

Commercial and managed properties

  • Grand Prairie's cross-connection program is more likely to touch commercial hazards, multifamily sites, and managed facilities.
