Who approves the parts and materials list in the code?

• A. Director of the Division of Plumbing
• B. State Plumbing Board
• C. Committee
• D. Architect

Answer: (C)

In this area, the group responsible for deciding which products and materials meet the code is the committee. This committee specializes in evaluating equipment, fittings, and materials, checking them against standards and tests to ensure they conform to the code’s requirements. Their approval creates the official parts and materials list that installers and inspectors rely on. The director of the division handles administration and day-to-day operations, not the technical vetting of every product. The board sets policy and adopts code changes, but the detailed approval of specific parts typically rests with the committee. An architect designs the system, but does not approve code-listed products.
