What is it

What is Backflow and Why is it a Risk?

Backflow happens when water reverses direction and flows from your property back into the city’s water supply.

This can occur due to:

  • Back-siphonage – sudden drops in city water pressure.
  • Backpressure – excess pressure from boilers, pumps, or internal plumbing systems.

The biggest danger? Cross-connections — points where clean drinking water meets contaminants. For example, lawn irrigation systems often contain fertilizers and chemicals. If backflow happens, those substances can enter the drinking water supply and put the entire community at risk.

Frequently Asked Questions (FAQ)

Yes. Texas law requires annual backflow testing for properties with irrigation systems, fire sprinklers, or other cross-connection points. The test must be performed by a state-licensed backflow prevention assembly tester.

The average cost for backflow testing in Texas ranges from $75 to $150 per device, depending on the type, location, and number of assemblies. Some providers offer discounted rates for multiple devices.

To become certified, you must complete a TCEQ-approved backflow prevention assembly tester course, pass the written and practical exams, and hold an active plumbing or irrigator license. Certification must be renewed every three years.

Backflow prevention assemblies must be tested once every 12 months as required by state and local regulations. Certain high-risk systems may require more frequent inspections.

No. Only licensed and certified backflow testers can legally perform and submit test reports in Texas. Homeowners or unlicensed individuals are not permitted to conduct official tests.

Backflow testing ensures that your prevention device is working properly to keep contaminated water from flowing back into the public water supply. This protects your property, your neighbors, and the entire community’s drinking water.
