Current Maine Journeyman format: the exam contains 80 multiple-choice questions, has a three-hour time limit, and requires 70% to pass, or 56 correct answers. The exam is closed book, so preparation should focus on recall, plumbing math, diagrams, sizing methods and code concepts.
What Is the Maine Journeyman Plumber Exam?
The Maine Journeyman Plumber examination is part of the state licensing process administered through the Maine Plumbers' Examining Board and Prov. It tests plumbing knowledge across drainage, venting, water supply, backflow protection, fixtures, regulations and practical plumbing systems.
Unlike many contractor exams, the Maine Journeyman Plumber exam is closed book. That changes the study strategy. Candidates need strong recall of plumbing concepts, formulas, sizing methods, regulations and system relationships instead of relying on fast code-book lookup.
Exam answer: 80 questions, three hours, closed book, 70% passing score and 56 correct answers required.
Code distinction: Maine currently uses the 2021 Uniform Plumbing Code with Maine amendments for plumbing installations. The current Prov candidate bulletin still lists the 2015 Uniform Plumbing Code among the sources used to develop the Journeyman examination.
That difference matters. The code currently enforced in the field is not automatically the same edition shown in the examination-development reference list. Candidates should follow the current Maine and Prov exam information when studying specifically for the licensing exam.
