What must be ensured if a cleanout is concealed?

When a cleanout is concealed, the most critical requirement is that it must be accessible. Cleanouts are essential for maintaining plumbing systems because they provide access to the drainage system for clearing clogs and performing inspections. If a cleanout is hidden behind walls or other structures, it defeats the purpose of having it installed, as it would be challenging or impossible to reach when maintenance is needed.

Accessibility ensures that plumbing professionals can easily locate and use the cleanout when necessary, regardless of its location. While there may be other considerations regarding the aesthetics or structural integrity of the installation, the primary focus should always be on accessibility to allow for proper maintenance of the plumbing system. This is particularly important in preventing potential future plumbing issues from becoming significant problems due to inaccessible cleanouts.
