TCEQ
Backflow Testing
Requirements
Texas requires annual backflow assembly testing for most properties connected to the public water supply. Atlas is TCEQ-licensed to test, certify, and file compliance reports across DFW.
Texas TCEQ Backflow Testing Requirements
If your property has a backflow prevention assembly in Texas, chances are it must be tested by a licensed professional. Whether you own a commercial building, apartment complex, irrigation system, medical facility, restaurant, or industrial property, understanding these requirements helps ensure you remain compliant and protect the public water supply.
What is a Backflow Prevention Assembly?
A backflow prevention assembly is a mechanical device installed on a water system to prevent contaminated water from flowing backward into the public drinking water supply.
Backflow can occur when changes in water pressure create either:
- Backpressure — downstream pressure exceeds the supply line pressure
- Backsiphonage — a drop in supply pressure draws water backward
Without properly functioning assemblies, contaminants from irrigation systems, chemicals, boilers, fire suppression systems, or industrial equipment could enter the municipal water system.
Who Can Perform Backflow Testing in Texas?
Texas law requires anyone who tests or repairs a backflow prevention assembly to hold a valid license issued by the Texas Commission on Environmental Quality (TCEQ).
Licensed Backflow Prevention Assembly Testers are qualified to:
- Test backflow prevention assemblies
- Repair backflow prevention assemblies
- Certify testing results
- Submit reports to local water authorities when required
This applies to assemblies serving residential properties, commercial buildings, industrial facilities, and irrigation systems. Fire line backflow assemblies have additional requirements — a tester may only test and repair fire line assemblies when permanently employed by an Approved Fireline Contractor.
Texas Water Code Requirements
The licensing requirements are established under Texas Water Code Chapter 37, Occupational Licensing and Registration. The law requires:
- A valid TCEQ license before performing regulated work
- Successful completion of required training
- Passing the required licensing examination
- Ongoing continuing education
- Timely license renewal
The TCEQ also maintains an official public roster of licensed individuals.
Can Someone Test Their Own Backflow Device?
Generally, no. Even if you own the property, Texas requires testing to be performed by a licensed TCEQ Backflow Prevention Assembly Tester whenever a licensed test is required for compliance. Water providers typically will not accept reports from unlicensed individuals.
Does Texas Require Backflow Testing?
Yes.
Texas requires certain backflow prevention assemblies to be tested by a licensed Backflow Prevention Assembly Tester (BPAT).
Many cities and water utilities require annual testing of RPZ, DCVA, and PVB assemblies that protect commercial and residential water systems.
Your local water provider determines which assemblies require testing and how often.
How Often Must a Backflow Preventer Be Tested?
The testing frequency depends on your local water provider and the type of assembly installed. Many Texas municipalities require:
- Annual testing
- Testing after repairs
- Testing after relocation
- Testing when a device fails inspection
Some cities may have additional local cross-connection control requirements beyond statewide TCEQ regulations.

- 4Test each check valve and relief valve according to TCEQ procedures.
- 5Verify the assembly is operating correctly.
- 6Complete all required documentation.
- 7Submit reports to the water authority when required.
Most tests take between 20 and 45 minutes.
What Happens If My Backflow Device Fails?
A failed assembly does not necessarily need to be replaced. Many devices can be repaired using manufacturer-approved parts. After repairs are completed, the assembly must be retested to verify it meets performance standards before being placed back into service.
If the assembly cannot be repaired, replacement may be necessary. Atlas carries parts for most common assembly brands and can often complete repairs on the same visit.
Who Needs Backflow Testing?
Backflow testing is commonly required for:
- Commercial buildings
- Apartment complexes
- Restaurants
- Medical facilities
- Manufacturing
- Schools
- Irrigation systems
- Fire sprinklers
- Multi-tenant properties
Your water utility determines when a backflow prevention assembly is required.
Choosing a Licensed Backflow Tester
When hiring a contractor, verify they:
- Hold a current TCEQ BPAT license
- Use calibrated testing equipment
- Can repair assemblies if necessary
- Know your local water utility reporting requirements
- Provide complete documentation for your records
Choosing an experienced, licensed tester helps ensure your property remains compliant and avoids unnecessary delays or failed inspections.
Protecting the Public Water Supply
Without properly functioning assemblies, fertilizers, chemicals, bacteria, industrial fluids, and other hazardous substances could enter the municipal water system during pressure changes. Routine testing verifies these assemblies continue operating as designed.

TCEQ Backflow Requirements — FAQ
Is backflow testing required every year in Texas?
Many water utilities require annual testing, although requirements are established by the local water provider. Contact your utility or call Atlas at 214-519-4410 and we can help you find out what applies to your property.
Who regulates backflow testing in Texas?
The Texas Commission on Environmental Quality (TCEQ) regulates licensing requirements for testers, while local water utilities administer cross-connection control programs and set reporting deadlines and requirements.
Can a plumber perform backflow testing?
Only if they also hold a current TCEQ Backflow Prevention Assembly Tester (BPAT) license. A plumbing license alone does not authorize a person to certify backflow test results in Texas.
Can a failed backflow preventer be repaired?
Yes. Many assemblies can be repaired using manufacturer-approved parts and then retested before returning to service. Atlas carries parts for most common brands and can often complete repairs on the same visit as the test.
