What Is Backflow?

Backflow is when water (and possible contaminants) flows in the wrong direction, back into a drinking water system. Testing matters because cross connections or connections between potable and non-potable systems can release contaminants into drinking water if backflow occurs, and that backflow can be a serious public health hazard. 

How often is backflow testing required?

Annual inspections and testing of installed backflow prevention assemblies by a licensed tester are often required as per rules and regulations. Many local water providers require proof of annual testing and can take action for noncompliance, including discontinuing service in certain situations.

What Does a Backflow Tester Do?

A certified backflow tester performs a structured field test to confirm the assembly is working correctly. In simple terms, we check that internal valves and components are holding pressure properly and preventing reverse flow.

If an assembly fails, the next step is usually repair or replacement. Idaho rules also describe timelines and enforcement expectations for defective assemblies in the context of program requirements.

What Happens During Our Sprinkler Blowout Service

  • Water supply shut-off: We turn off the irrigation water supply to prevent any new water from entering the system.

  • Controller set for winter: We adjust or power down the sprinkler controller so it does not activate during winter.

  • Professional air connection: We connect commercial-grade equipment designed for irrigation systems, not small residential compressors.

  • Zone-by-zone blowout: Each sprinkler zone is cleared individually to safely remove water from pipes, valves, and sprinkler heads.

  • Proper pressure control: Air pressure and airflow are carefully managed to avoid damage to pipes and components.

  • Backflow protection: We winterize the backflow preventer correctly to reduce freeze risk.

  • Final system check: We confirm all zones are cleared, and the system is left in a safe winter-ready state.
