Backflow Testing in Dallas–Fort Worth

A backflow prevention assembly stops water from reversing out of an irrigation system, boiler, or commercial process back into the drinking water supply. Many DFW cities require these assemblies to be tested periodically by a certified tester and the results filed with the water department.

Requirements vary by city, so confirm your local schedule with your water provider.

Symptoms and problems

• • A notice from your city requesting a test report
• • A new irrigation system needing initial certification
• • An assembly that is leaking or discharging
• • A commercial property with required annual testing

Common causes

• • Debris fouling the check valves
• • Freeze damage to an above-ground assembly
• • Worn internal components after years of service

Typical solutions

• • Testing the assembly with certified gauge equipment

When to get professional help

Testing must be performed by a certified backflow tester for the results to be accepted by the city.
