Michigan Plumber License — What to Know

Michigan measures experience in hours (8,000 hours for journeyman). Michigan uses an IPC-based state code.

Key Code Sections to Master

The International Plumbing Code (IPC) exam covers water supply, drainage, venting, fixtures, water heaters, storm drainage, and special piping. Focus on the table for pipe sizing (Table 604.4 for water supply, Table 710.1 for drainage fixture units), minimum fixture requirements by occupancy type, and venting rules. Drainage fixture units (DFUs) are frequently tested via calculation questions.
