Professional Backflow Testing in Louisville, CO

Protecting your drinking water is not optional—it’s essential. At Kerwin Plumbing, we provide certified backflow testing services in Louisville, CO, to help homeowners and businesses safeguard their water supply and remain compliant with local requirements. Our experienced plumbers perform accurate testing, documentation, and recommendations to ensure your backflow prevention system is functioning properly and protecting against contamination.

Backflow issues can develop silently, but the consequences can be serious. That’s why routine testing by trained professionals is critical for both safety and compliance.

What Backflow Testing Is and Why It Matters?

Backflow occurs when water flows in reverse within a plumbing system, allowing non-potable water, chemicals, or contaminants to enter the clean water supply. A backflow prevention device is designed to stop this reversal—but only if it’s operating correctly.

Professional backflow testing verifies that your device is responding properly under pressure changes. This testing helps:

  • Protect potable water from contamination
  • Ensure compliance with municipal regulations
  • Identify failing or worn components early
  • Reduce health and safety risks for occupants

Our certified technicians perform testing using calibrated equipment and follow all required testing procedures for accurate, reliable results.
