About this app

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.

STUDY ANYWHERE
Everything works offline. No account, no sign-up, no ads, no data collection.

Start free with a preview of every mode. Unlock the full library with a weekly, monthly or annual subscription, or a one-time lifetime purchase — all four unlock identical content; duration is the only difference. Subscriptions renew automatically unless cancelled in Google Play; the lifetime unlock is a one-time purchase.

This app is an independent study aid and is not affiliated with, endorsed by, or sponsored by any state licensing board, PSI, Prov, the International Code Council, or IAPMO. It is not the licensing exam and does not confer a license. It provides exam study material only — not code advice for live work; always follow your jurisdiction's adopted code.
