Highlights

Annual testing remains the norm for non-residential assemblies.
Mesquite adds a $25 annual fee per assembly on the utility bill.
The City requires the Backflow Inspector to be present to observe the test.

Workflow

Confirm whether the assembly is residential-installation-only or part of the annual commercial cycle.
Use a Mesquite-registered backflow tester.
Call the Backflow Inspector at 972-216-6947 before testing so the City can witness the test.

Residential

Mesquite residential assemblies are mainly an installation workflow rather than a blanket annual workflow, which makes it easy for homeowners to confuse their obligations.
Residential irrigation users still need a permit, a registered tester, and a witnessed test before final inspection.

Commercial focus

Commercial and managed properties

Commercial properties sit on the annual side of the Mesquite program, and the City publishes a detailed assembly guide that reaches beyond a basic consumer explainer.
Mesquite also distinguishes fire line testers from general testers on the official list, which matters for larger properties and higher-risk systems.
