What to check for League City

League City's page centers on high hazard devices and BSI reporting rather than a separate public fire-line section.

  • Due basis: League City says TCEQ requires backflow devices or assemblies to be tested upon installation and at least once annually, with BSI mailing official annual certification notices and maintaining electronic records.
  • Notice or device clue: Look for the CCN, account number, BSI record, device ID, or assembly serial from the reminder.
  • Who is affected: League City customers with backflow prevention devices or assemblies, especially high hazard locations receiving BSI annual certification notices.
  • Acceptance rule: Report acceptance depends on the named portal and the utility-approved tester route; keep proof that the report was submitted.
  • Program phone: 281-554-1429
Local signals

Signals that matter before you act

  • High hazard classification controls the strongest annual signal.
  • Repairs and replacements must be done by a licensed tester and permitted by the City.
  • BSI Online remains the accepted reporting path.
