How often should annual inspections of backflow prevention assemblies and air gaps be conducted?

Backflow prevention assemblies and air gaps play a crucial role in protecting potable water supplies from contamination. Regular inspections are necessary to ensure that these systems are functioning properly and complying with safety standards. The International Plumbing Code stipulates that annual inspections of backflow prevention assemblies and air gaps should be conducted to monitor their effectiveness and to identify any issues that could jeopardize water quality.

Conducting inspections on an annual basis strikes a balance between ensuring safety and practicality. These inspections allow for timely maintenance and repairs to be made before any potential cross-connections or failures occur. By adhering to this annual schedule, plumbing inspectors and water system operators can manage resources efficiently while still maintaining high standards for public health and safety. This annual requirement is supported by many local and state regulations, which aim to provide uniformity in water quality assurance practices.
