Which plumbing code governs plumbing in Maine?

The correct answer is the Maine Plumbing and HVAC Code, which sets the standards and regulations for plumbing systems within the state. This code is specifically focused on ensuring safe and effective plumbing practices, including the installation, maintenance, and repair of plumbing systems. It provides guidelines that plumbing professionals must follow to ensure compliance with state regulations.

While the Maine Uniform Building and Energy Code (MUBEC) plays a crucial role in regulating building standards and energy efficiency, it is the Maine Plumbing and HVAC Code that directly addresses plumbing-related issues. The other codes like the Maine Water Supply Code and the Maine Residential Building Code cover specific aspects of plumbing and construction but do not encompass the full range of plumbing regulations that the Maine Plumbing and HVAC Code does. Thus, for questions specifically regarding plumbing governance in Maine, the Maine Plumbing and HVAC Code is the authoritative source.
