Book updated Jun 2026. Michigan Plumbing Code is the current code. It is required by law in Michigan to be licensed through the state to legally perform any plumbing work. Only licensed plumbing contractors can operate a business and advertise services, obtain commercial insurance, pull building permits and pass inspections, bid on public and government projects.
We create these self-practice test questions module (with 150+ questions) referencing both the requirements set forth in the adopted IPC as well as some MI specific information currently valid in the plumbing trade. The focus is on code compliance – an answer can be correct only if it does not violate the code. Each question comes with an answer and a short explanation which aids you in seeking further study information. We want to make sure these questions are tough enough to really test your readiness and draw your focus to the weak areas. You should use this product together with other study resources for the best possible exam prep coverage.
