Use this as the source-backed check before treating the fire line route as a completed compliance item.
Workflow
Workflow
- Confirm whether the fireline assembly is customer-side or in a SAWS-controlled right-of-way location.
- Use a licensed fireline tester rather than a generic backflow-only contractor.
- Make sure the passing result reaches the SAWS and BSI workflow before the deadline window closes.
Residential
- Residential users most often see SAWS through annual notices for irrigation, fire sprinkler, septic, well, or alternative-water conditions.
- SAWS is not a one-size-fits-all page because internal and external assemblies can sit on different compliance tracks.
Commercial and managed properties
- Commercial owners should expect SAWS customer service inspection and development workflows to overlap with annual testing when hazard conditions change.
- The public materials are clearer on BSI workflow and notice handling than on retail tester pricing.
