What is a backflow prevention assembly tester?

Backflow Prevention Assembly Testers are professionals who inspect, test, and maintain devices designed to prevent contaminated water from flowing back into clean water supplies. They ensure that backflow prevention assemblies, such as valves and mechanical devices, are functioning properly in plumbing systems. Their work helps protect public health by keeping drinking water safe from pollutants and contaminants. These testers are often certified and follow regulatory standards set by local or state authorities.
