What is the minimum diameter of an access panel required for plumbing fixtures with concealed slip joint connections?

The correct answer is: 18

The minimum diameter of an access panel required for plumbing fixtures with concealed slip joint connections is 18 inches. This size is designed to ensure that there is adequate access for maintenance, repairs, and inspection of plumbing connections that are concealed behind walls or other structures. Having a diameter of this size allows a contractor or plumber to work comfortably without causing damage to surrounding materials, and it ensures that it is suitable for reaching not just the slip joints but also other components that may need attention. Choosing a smaller diameter would not provide sufficient access for effective work on these connections, while a diameter larger than necessary may not be feasible or cost-effective in practical application. Therefore, the 18-inch measurement strikes a balance between accessibility and practicality in plumbing installations.
