A wall hung commercial single carrier back to back shall require a chase with a minimum inside clear space of how much?

For a wall-hung commercial single carrier installed back to back, the Omaha plumbing code specifies that a chase must have a minimum inside clear space of 16 inches. This requirement ensures that there is sufficient room for both the installation and maintenance of the plumbing fixtures.

The 16-inch width accommodates the necessary plumbing connections and drainage lines, allowing technicians easy access during service or repairs while also providing room for proper ventilation and compliance with codes on spacing and safety. This space is critical for ensuring that fixtures do not interfere with one another and that they can function properly without risking blockages or other plumbing issues.

Other sizes mentioned may not provide adequate room to install connections properly, which could lead to complications in serviceability or performance, making 16 inches the optimal requirement for this application.
