The option regarding ball or slip joints is correctly identified as being able to be repacked without needing a work permit because these types of joints are designed for easier maintenance. Ball and slip joints typically allow for straightforward access to the inner components, enabling them to be repacked quickly and efficiently during routine maintenance without the need for extensive safety measures or permits.

In contrast, welded or threaded joints generally involve more complicated procedures due to the permanent nature of their construction and may require inspections or permits to ensure safety regulations are upheld during any work done on them. Similarly, mechanical or flanged joints may also necessitate permits because they can be critical to the overall integrity of a system and require careful handling. Lastly, while PVC or copper joints might be simpler in some respects, their specific handling and potential safety concerns could also require a work permit for any necessary maintenance or repair operations.

By understanding these distinctions, one can appreciate why ball or slip joints are uniquely suited for repacking without additional regulatory considerations.
