How often must piping tightness tests be conducted for American-style suction piping?

For American-style suction piping, regulatory requirements typically dictate that tightness tests be conducted every three years. This frequency is based on various factors, including the potential for leaks and the overall integrity of the piping system. The three-year interval helps ensure that any issues with the piping system can be identified and addressed before they become serious problems that could lead to environmental contamination. It also aligns with best practices in maintaining underground storage systems, supporting preventive measures rather than reactive ones.

Tightness testing is essential because it helps ensure that the piping does not leak, which is critical for protecting both the environment and public health. Conducting these tests regularly allows operators to detect any deterioration or weaknesses in the system, ensuring compliance with safety regulations and helping to uphold operational standards.
