Texas Backflow Testing Requirements: What Homeowners Need to Know
TCEQ rules, local deadlines, and what Texas property owners should know about backflow testing requirements.
If you've received a backflow notice from your city, you're not alone. Testing requirements are set by each city or municipality under TCEQ rules. Commercial and fireline assemblies are commonly required to be tested annually. Residential irrigation testing is required in some cities, including Princeton, Wylie, Lavon, Farmersville, and Aubrey, but not in others, including Plano, Frisco, and Carrollton.
Who has to test?
Testing requirements depend on the assembly and the municipality. They commonly apply to:
- Commercial buildings
- Fire sprinkler (fireline) systems, including apartments, townhomes, and most homes over 5,000 square feet
- Domestic assemblies, such as those used with water softeners
- Residential irrigation systems where the city requires testing
Who can do the test?
Only a Texas-licensed Backflow Prevention Assembly Tester (BPAT) can perform the test and submit the results. All Next Day Backflow Testing technicians are licensed and background-checked.
What's the deadline?
Each city sets its own due date based on when your assembly was installed. Most homeowners get an annual notice in the mail. Miss the deadline and the city can fine you or shut off service.
