What is a cross connection control device inspector?

Cross Connection Control Device Inspectors are professionals responsible for inspecting, testing, and maintaining backflow prevention devices to protect drinking water supplies from contamination. They ensure that cross connections—where potable water could be exposed to pollutants—are correctly identified and controlled in buildings and public water systems. These inspectors typically work for utilities, municipalities, or private companies, and must be knowledgeable about plumbing systems, local codes, and state regulations. Their work helps maintain public health and safety by preventing the reverse flow of contaminated water into clean water systems.
