What to check for Mesa

Mesa keeps separate resources for fire contractors, which makes the fire-line path stronger than a generic annual-testing page.

  • Due basis: Mesa sends annual notices to regulated customers, requires recognized testers to submit results through the backflow portal within seven days of service, and requires immediate retesting after repair or maintenance.
  • Notice or device clue: Look for the utility name, service address, assembly serial number, account or notice ID, and due date.
  • Who is affected: Commercial, industrial, irrigation, fire-sprinkler, and dedicated-landscape-meter customers, plus residential sites that city code and plumbing rules identify as cross-connection hazards.
  • Acceptance rule: Report acceptance depends on the named portal and the utility-approved tester route; keep proof that the report was submitted.
  • Program phone: 480-644-6462
