How often should device performance tests be conducted?

Conducting device performance tests upon certification and every two years thereafter is essential for ensuring that the radon mitigation systems are functioning effectively. This approach balances the need for regular monitoring with practical considerations, as it establishes a consistent schedule for evaluating the performance of the system.

Regular testing is crucial because radon levels can vary due to changes in environmental conditions, occupancy, or alterations in the home. By performing tests upon certification, it ensures that the system is properly installed and functioning as intended from the outset. Subsequent tests every two years help to confirm that the system continues to operate effectively over time, thus safeguarding the health of occupants by ensuring that radon levels remain low.

The recommended interval of two years aligns with guidelines set by organizations involved in public health and safety, which emphasize the importance of regular monitoring in radon mitigation practices. This systematic approach provides homeowners adequate reassurance about their indoor air quality and the efficacy of their radon mitigation systems.
