Slip joint compression type waste line connections shall ______________________.

Slip joint compression type waste line connections are designed to allow for connections that can be easily dismantled and reassembled. The requirement for these connections to be accessible for inspection and repair is critical because it ensures that any potential leaks or problems can be identified and fixed without significant effort. This accessibility facilitates routine maintenance and contributes to the overall functionality and safety of the plumbing system.

While options such as being exposed or accessible in other contexts could seem beneficial, they do not specifically address the importance of being able to perform inspections and repairs effectively. The requirement to be installed at least 12 inches above the floor is more about managing potential sludge accumulation than about ensuring that the connections remain operable and serviceable. Hence, emphasizing the need for accessibility for inspection and repair aligns directly with good plumbing practices and code requirements for maintaining a reliable waste management system.
