In Maine, a Journeyman Plumber means any person who customarily performs the work of installing plumbing and drainage under the employment and direction of a master plumber or, not being a master plumber, does plumbing repair work as a regular part-time occupation. A major focus of the exam is code compliance.
We create these self-practice test questions module referencing the concepts and principles currently valid in the written exam. 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. Think of these as challenges presented to you so to assess your comprehension of the subject matters. The goal is to reinforce learning, to validate successful transference of knowledge and to identify areas of weakness that require remediation.
