What to check for Mesquite

Mesquite's commercial assembly guide treats fire lines as a separate technical case and pairs that with a tester list that explicitly labels fire line testers.

  • Due basis: Mesquite says all backflow prevention assemblies must be tested upon installation and thereafter annually by a licensed backflow tester, excluding residential assemblies that require testing upon installation. The tester must be registered with the City, contact the Backflow Inspector before testing, and complete the observed test appointment.
  • 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 sites, restaurants, dental offices, residential irrigation systems, fire line assemblies, and other properties where Mesquite requires a backflow assembly to protect the public water system.
  • Acceptance rule: Report acceptance depends on the governing tester route and the utility's submission method; confirm status before scheduling.
  • Program phone: 972-216-6947

Local signals

Signals that matter before you act

  • Fire lines require a stainless-steel RP assembly under the published guide.
  • The official tester PDF repeatedly labels fire line testers instead of burying them in a generic list.
  • The same witnessed-test rule applies, so the inspector still has to be present.

What costs or fees should I expect for Mesquite?
