Montana Plumber License — What to Know

Montana requires 75% to pass. Montana uses the Uniform Plumbing Code (UPC).

Key Code Sections to Master

The Uniform Plumbing Code (UPC) exam covers similar topics to the IPC but with different numbering. Focus on water supply pipe sizing (Table 6-4), drainage fixture units (Table 7-3), venting requirements (Chapter 9), and fixture installation requirements (Chapter 4). The UPC is generally considered stricter on venting requirements than the IPC.
