At maximum intervals of how many feet should one-inch O.D. smooth-wall tubing be supported horizontally?

• A. 6 feet
• B. 8 feet
• C. 10 feet
• D. 12 feet

Answer: (B)

One-inch O.D. smooth-wall tubing should be supported horizontally at maximum intervals of 8 feet to ensure stability and minimize the potential for sagging or bending under weight or thermal expansion. This requirement is grounded in plumbing codes and standards that aim to maintain the integrity of the piping system. Proper support intervals help reduce stress on the joints and the tubing itself, contributing to the longevity and reliability of the installation. By following this guideline, inspectors can ensure that the plumbing systems in residential constructions are well-supported and comply with safety and performance standards.
