Who holds custody of the APML?

The correct answer is that the director holds custody of the APML, which stands for Approved Plumbing Material List. The director is responsible for overseeing the regulations and standards associated with plumbing materials used in construction and renovation projects. This includes maintaining the validity and integrity of the list, ensuring that all plumbing work is done using materials that meet legal and safety standards.

While plumbing inspectors, project managers, and owners play significant roles in the plumbing industry, they do not have the regulatory authority or designated responsibility for managing the Approved Plumbing Material List. The inspector enforces plumbing codes and standards during inspections, the project manager oversees the execution of projects, and the owner is concerned with the overall management and completion of their property projects. However, it is the director who maintains custody of the list and ensures compliance with regulations, which is crucial for the safety and success of plumbing installations.
