What is NOT a requirement for minor repairs made after a pressure test?

The correct response identifies that a pressure test after each minor repair is not a requirement. In the context of regulatory practices, minor repairs may not necessitate an extensive evaluation like a full pressure test, which is often reserved for significant repairs or installations. This understanding helps in efficient resource management and prioritization of safety checks based on the severity of the repairs undertaken.

The other options are integral to maintaining safety and ensuring compliance with best practices after conducting minor repairs. Inspecting connections with leak-detection methods is critical, as it helps prevent leaks that could lead to hazardous situations. Additionally, the use of noncorrosive leak-detecting fluids is essential to ensure that no harmful substances are introduced into the environment or the system being repaired. Finally, ensuring compliance with local authority regulations is crucial for all activities related to infrastructure to meet safety standards and legal requirements. These measures collectively uphold industry standards and protect public safety, which is why they are considered requirements, unlike the pressure test for minor repairs.
