Journeyman Plumber Exam Guide

Pass your journeyman plumber exam by drilling what state tests actually ask — trap arms and vent distances, drainage slopes and fixture units, backflow devices by hazard, gas sizing by the longest-length method, and the offset math — instead of rereading the code book cover to cover.

Journeyman Plumber Study Guide is a focused, fully offline companion for state journeyman plumbing license exams. State tests differ in details, but they draw from the same model-code core — this app organizes that core into ten weighted subject areas so you can drill your weakest area or work through the whole exam.

FIVE WAYS TO STUDY
• Flashcards — tap to reveal, tagged by subject area
• Multiple-choice questions set in real jobsite scenarios — a trench call, a failed inspection, a suspect backflow connection — each with a worked explanation
• True/false drills built from the misconceptions that cost marks
• Term-matching game — pair the trade's vocabulary in rounds of five
• Searchable glossary plus a formulas & tables reference — offset multipliers, psi-to-head conversions, slopes, test pressures, recovery math, each with the trap the exam sets

TEN SUBJECT AREAS
• General Regulations & Code Administration — permits, inspections, testing, materials and workmanship
• Water Supply & Distribution — sizing, pressure limits, materials, disinfection and protection
• Drainage, Waste & Vent Systems — slopes, fitting rules, trap arms, every venting method
• Traps, Cleanouts & Interceptors — seals, prohibited traps, clearances, grease and oil separation
• Backflow Prevention & Cross-Connection Control — air gaps, RPZ, DCVA, PVB and where each belongs
• Fixtures & Water Heaters — clearances, scald protection, T&P discharge, pans and venting
• Storm Drainage, Sewers & Septic — roof drainage, separation rules, septic systems
• Fuel Gas Piping — sizing, materials, sediment traps, CSST bonding, testing
• Isometrics, Plan Reading & Plumbing Math — offsets, rolling offsets, volumes, pressures and grades
• Jobsite Safety & Rigging — trenching, confined spaces, ladders and electrical safety

BUILT FOR STATE EXAMS
Content follows the common core behind PSI- and Prov-style journeyman outlines, teaching the principles shared by the major model codes — and flagging the places where they differ, so you know what to verify against your state's adopted code.
