Journeyman Plumber Exam Study Guide 2027–2028 | Plumbing License Prep, IPC and UPC Codes, 200 Practice Questions (PDF)

Prepare for your state or local journeyman plumber license exam with a complete study guide that teaches both model plumbing codes used for journeyman exams: the International Plumbing Code (with the fuel gas and residential plumbing chapters many states add) and the Uniform Plumbing Code. Wherever the two codes differ, the guide shows both values side by side, so you learn your adopted code and spot the other code's value as a wrong answer.
