Who is typically responsible for testing backflow preventers?

Certified backflow testers are the individuals specifically trained and authorized to inspect, test, and maintain backflow prevention devices. The primary purpose of a backflow preventer is to protect the potable water supply from contamination due to reverse flow, which could occur from various pressure changes in a water system.

Testing backflow preventers is a specialized task that requires knowledge of the devices and the plumbing systems they are part of, along with the ability to conduct the necessary tests according to established standards and regulations. Certified testers are knowledgeable about the local codes and the proper testing procedures to ensure that the devices function correctly and provide the intended protection.

While homeowners may take an interest in ensuring their plumbing is safe, and municipalities or water utility companies may have roles in setting guidelines or policies, the actual testing and verification that backflow preventers are working as intended fall under the domain of certified backflow testers. These professionals possess the credentials and skills necessary to perform accurate assessments and maintain compliance with safety regulations.
