Journeyman Plumber Practice Test Questions 2026: Worked Examples

Journeyman Plumber Exam 2026: Format, Code Book and How to Pass

A journeyman plumber licence in the United States is issued by a state (or in some states a city or county) licensing board, and many boards require a written exam on the plumbing code before the licence is granted. Licensing requirements, exam formats and code editions vary by jurisdiction: many states use the International Plumbing Code, others the Uniform Plumbing Code. As one published example, the Oklahoma Construction Industries Board's PSI bulletin (effective 11 September 2026) sets the Plumbing Journeyman and Natural Gas exam at 85 questions in 180 minutes, open book, with 70% correct to pass from 1 November 2026, over 10 content areas from water supply, drains and vents to isometric drawings, fuel gas and construction safety. Oklahoma's adoption of the 2024 International Plumbing Code and International Fuel Gas Code, with amendments, took effect on 14 September 2026, and the 2024 codes became an option for that exam on 8 October 2026, during a transition in which either edition may be used. Check your own board's candidate bulletin for the code, the number of questions, the time and the reference books allowed.
