Oregon Plumber License — What to Know
75% passing score required. Oregon uses a UPC-based state code with its own amendments.
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.
