BACKFLOW SAFETY & PROTECTION

Why Backflow Testing Matters

Backflow testing is one of the most important steps in protecting your home or business from contaminated water. When pressure changes occur in a plumbing system, dirty or non-potable water can be pulled backward into clean drinking lines — creating a serious health hazard.

Regular testing ensures your water remains safe, your irrigation or fire protection systems operate correctly, and your property stays compliant with city and state regulations. For Rockwall homeowners, commercial buildings, and irrigation systems, annual testing is required to prevent cross-connection issues and maintain the integrity of the public water supply.

BACKFLOW PREVENTION: FREQUENTLY ASKED QUESTIONS

What is Backflow?

Backflow is the unwanted reversal of water flow in a plumbing system. When this occurs, contaminated or non-potable water can enter clean drinking water lines, creating a serious public health hazard. This is why cities like Rockwall require annual testing.

What is a Backflow Prevention Assembly?

A backflow prevention assembly is a mechanical device installed on irrigation systems, fire lines, commercial plumbing systems, or other service lines to keep contaminated water from flowing back into the potable water supply.
Different assemblies are required depending on the hazard level and type of system being protected.

Who Regulates Backflow Protection in Texas?

Backflow prevention is regulated by the Texas Commission on Environmental Quality (TCEQ), which sets statewide rules to safeguard Texas public water systems. TCEQ also oversees licensing for certified backflow testers and mandates annual calibration of testing equipment.

Testing, Inspection, and Certification Requirements

Because mechanical devices wear down over time, backflow assemblies must be tested regularly to verify they are functioning correctly and protecting the water system.

TCEQ regulations require:

  • All backflow assemblies must be tested upon installation.

  • Assemblies protecting against health hazards must be tested every 12 months.

  • Test records must be kept by both the tester and the water supplier for at least three years.

  • Only licensed backflow testers may perform certified tests.

Why Did I Receive a Notice From the City or Your Water Supplier?

Rockwall and surrounding North Texas cities follow TCEQ guidelines through a cross-connection control program. When you receive a notice, it means the city is ensuring all assemblies are tested, maintained, and functioning properly to keep the public water system safe.

If you received a compliance letter or notice, LPS can complete your test quickly, provide documentation, and—when required—submit results directly to the city or water provider.
