MT Journeyman Plumber study guide
MT Journeyman Plumber · Work through your exam, one topic at a time.
The Montana Journeyman Plumber license is a credential issued by the Montana Board of Plumbers, part of the Department of Labor & Industry's Employment Standards Division, which oversees occupational and professional licensing boards mandated by state law. It is for plumbers who have completed apprenticeship training and want to work as journeymen under a master plumber, and for out-of-state journeymen seeking Montana licensure. The Board's published materials cover four practical areas: Uniform Plumbing Code application and installation standards; plumbing fixtures, fixture tables, and fixture unit sizing; piping, materials, joints, and water and drainage system installation; and Montana statutes, administrative rules, and licensing requirements. Montana has adopted the 2021 Uniform Plumbing Code as of June 10, 2022, alongside the 2020 NEC and the 2021 International Codes, so code-study time should center on the 2021 UPC and the state's published code amendments. The MT Journeyman Plumber study guide has 4 sections and about 1,527 words.
