Welcome To RDL Backflow Testers
What is Backflow?
Backflow happens when the normal flow of water is reversed from its intended direction in any pipeline or plumbing system. The danger of backflow comes with the potential for cross-contamination: when water that has contacted chemicals or hazardous compounds flows back into the drinking water system. A backflow prevention device is required to prevent this occurrence. Its sole job is to prevent drinking water from being contaminated due to backflow.
