Exam guide
Independent journeyman and master plumber license study guide for state-specific code review, drainage, venting, traps, water supply, fixture units, and trade math.
Plumbing candidates need state-bulletin checks, code vocabulary, and repeated calculation and layout decisions.
Start with a short set, mark the misses, then review the exact topic that caused the miss. This keeps study time tied to evidence from your own answers instead of a vague topic list.
