Read these before acting on the San Antonio workflow
How we verify local backflow rules
What counts as an official source, how local utility pages override generic assumptions, and how stale pages are re-verified.
Backflow reporting portals
How BSI, SwiftComply, and utility customer portals change the real testing workflow after the field work is done.
Anniversary date vs calendar deadline
Why some utilities track backflow tests by anniversary date, while others push owners into a calendar-season or hard-date deadline.

Why the local trigger is rarely just residential versus commercial, and how utilities actually split hazard, irrigation, multifamily, and managed-property cases.
