What Backflow Testing and Prevention Includes

Backflow Prevention Device Testing

We test your backflow prevention assembly to verify that it is operating correctly and protecting the drinking water supply from contamination caused by reverse water flow.

Cross-Connection Evaluation

Our technicians inspect the system for potential cross-connections that could allow pollutants, chemicals, or non-potable water to enter the clean water supply.

Compliance Verification

Many irrigation systems, commercial properties, and other plumbing systems require routine testing. We help confirm that your device meets applicable testing and compliance requirements.

Backflow Preventer Repairs

If a device does not pass inspection, we can identify the cause of the failure and recommend the appropriate repair to restore proper protection.

Device Replacement Services

When repairs are no longer practical or cost-effective, we can replace the backflow prevention assembly with a properly sized device for your system.

Testing Documentation and Reporting

After testing is complete, we provide the necessary documentation and reporting required for many residential, commercial, and irrigation system testing programs.

Excellent service from start to finish! I had a leaking toilet that needed to be replaced. Pete made the entire troubleshooting process and replacement stress-free. He was friendly, courteous and took the time to explain his findings and answer my questions. I also ended up upgrading an additional toilet. I appreciate the quality workmanship and would highly recommend Draingo to others.
