Georgia Journeyman Plumber Exam — Practice Test
What's on the exam
Questions per topic, out of 100The real Georgia Journeyman Plumber Exam is 100 questions, 300 minutes, and you need a scaled score of 70 to pass. Questions pull from 9 topic areas ranging from Georgia code compliance to pipe math to gas system testing.
This site gives you two ways to practice:
Free practice exam: 10 questions per attempt, drawn from a limited pool. You can retake it as many times as you want. Use it to get a feel for how questions are written and what the format demands before you commit to serious prep.
Full practice exam (paid): 100 questions, 300-minute timer — same structure as the real thing. Questions are pulled from a pool of 440+ items, so each attempt gives you a different set. No two exams are identical. Every question maps to the official topic list provided by the exam developer. If you want to pass on your first try, this is where you build that confidence.

Comply with General Laws 5 items
This covers the Georgia Construction Industry Licensing Board (CILB): how complaints are filed, how licenses are renewed, and what the board can and cannot do. You'll also need to know Georgia's underground utility location law — what a contractor must do before digging, who to call, and the legal timelines under O.C.G.A. § 25-9. ADA employment rules show up here too: reasonable accommodation, undue hardship, essential job functions, and when a medical examination is permitted. ANSI accessibility and state water conservation law round out this section. Five questions is a small count, but these are often free points if you've read the statutes.
Comply with Regulations 15 items
Fifteen questions means this topic matters. Know the Georgia State Plumbing Code, the SBCCI codes for plumbing and gas, and OSHA (29 CFR). You need to understand the permit and inspection process — what triggers a permit, what inspections are required for plumbing and boilers. Georgia's State Trenching Law is here, and so is the Georgia State Boiler Code. Exam questions in this section frequently test the difference between what a code says and what an inspector can require. The appeal process — specifically what qualifies as a valid basis for appeal — is a favorite question type.
Work Planning and Organizing 7 items
Seven questions on takeoffs, scheduling, and drawings. For takeoffs, you need to read a plan, identify materials, and build a bill of materials. Nameplates on pumps, water heaters, backflow preventers, and lift stations appear here — you need to interpret the data on them, not just recognize the equipment. Isometric drawings and riser diagrams are fair game. Know all three scheduling methods: calendar, bar chart, and Critical Path Method (CPM). One subtopic specifically covers precedence of codes — when manufacturer instructions conflict with code, or local ordinance conflicts with state law, which one wins?
Perform Pipe Cutting and Joining Activities 10 items
Ten questions, and they are specific. Know the right tool for each material: snap-type chain cutter and hammer-and-chisel for cast iron, tubing cutters for copper, scissor-type cutters and saws for plastic, hand or power pipe cutters for steel. Cutting concrete pipe gets its own category. On the joining side, cast-iron soil pipe connections — lead and oakum, rubber-type seals, no-hub connectors — are all tested. The exam may ask you which gasket standard applies; for rubber gaskets under the IPC, see International Plumbing Code 2024, Chapter 15 (ASTM C564), referenced in Section 705.3.2.
Perform Plumbing Systems Installation Activities 21 items
The biggest topic at 21 questions. You must be able to read plans and spec sheets, then apply what they say. Water supply sizing, drainage system sizing, and gas pipe sizing all appear here, and sizing questions require you to use code tables — not just estimate. Fixture and fitting assembly questions test whether you can follow manufacturer instructions. You'll also be asked about locating and marking holes in walls, ceilings, and floors. Budget your time here; 21 questions at a normal pace is still roughly an hour of this exam.
Perform System Testing Activities 7 items
Know every test method for every system. Water distribution: air, hydrostatic, water tests. Sanitary and drainage: water, smoke, air, and peppermint tests. Gas lines: air pressure test procedures under IFGC 2024, Section 406.4. Backflow preventer certification testing and potable water sterilization and certification are included. Test gauge requirements and pressure increments are specifically called out — knowing the pressure levels and gauge specs is not optional.
Perform Maintenance and Repair Activities 15 items
Fifteen questions on what goes wrong and how to fix it. Gas leak location — soapy water and gas detectors — is covered alongside gas appliance service: burner cleaning, valve checks, venting. Electric water heater element replacement and control checks appear here. Drain obstruction location and removal, backwater valve cleaning, and faucet or valve leak repair round out the section. Relief valves on water heaters — sizing, pressure ratings, discharge routing — come up repeatedly.
Safety-Related Issues 15 items
Fifteen more questions, matching Comply with Regulations for weight. Hot water heater and pressure vessel venting — slope, classification, sizing, routing, termination — is the biggest subtopic. Gas piping safety covers testing and support requirements. Backflow prevention control gets its own slot. Personal safety covers trenching hazards, poisonous gases, and faulty equipment. PPE selection, use, and employer requirements are tested, and so is fall protection: guardrail systems, safety nets, and personal fall arrest systems.
Calculations 5 items
Five calculation questions requiring real math. Pipe offset work uses 45° constants for diagonal, rise, and run. Volume calculations cover cylinders, rectangular solids, and spheres. Water pressure and head conversions (psi to feet of head) appear. Grade and percent grade calculations for drainage pipe are tested, as are decimal-to-fraction conversions and metric conversions. Pipe capacity and gallons-per-foot calculations using pipe data round out this section. Get comfortable with the Mathematics for Plumbers and Pipefitters reference material before exam day.
Sample 1 — Gas Pipe Sizing
Question: What is the smallest pipe size that can serve the 60,000 Btuh unit heater over the 35-ft run?
- A. 1-1/4 inch
- B. 1/2 inch
- C. 3/4 inch
- D. 1 inch
Correct Answer: B — 1/2 inch
Convert demand first: 60,000 Btuh ÷ 1,000 = 60 cfh. Then go to the sizing table. Using the 40-foot row (always round up from actual run), a 1/2-inch Schedule 40 metallic pipe carries 81 cfh for natural gas at inlet pressure under 2 psi with a 0.5 in. w.c. pressure drop. That exceeds the 60 cfh demand, so 1/2 inch is sufficient. Candidates lose points here by forgetting to convert Btuh to cfh before hitting the table.

Sample 2 — Code Appeals
Question: A gas contractor wants to appeal a code official's decision to the board of appeals. Which of the following is a valid basis for filing the appeal?
- A. The inspection was conducted without 48 hours' advance written notice to the contractor
- B. The permit fees charged are higher than fees in neighboring jurisdictions
- C. An equally good or better form of construction is proposed than what the code official required
- D. The contractor's preferred material supplier is not on the code official's approved list
Correct Answer: C — An equally good or better form of construction is proposed
The code lists three valid grounds for appeal: the true intent of the code was incorrectly interpreted; the code provisions do not fully apply; or an equally good or better construction method is proposed. Fee disputes, supplier preferences, and inspection scheduling complaints are not listed as valid grounds. Knowing this distinction — what qualifies versus what doesn't — is exactly what the exam tests.

Sample 3 — Forced Draft Venting
Question: When an appliance equipped with a mechanical forced draft system creates a positive pressure in the venting system, what is required of the venting system?
- A. It must be lined with a UL 1777-listed chimney lining system
- B. It must be designed for positive pressure applications
- C. It must be constructed of Type L vent material only
- D. It must be increased by two pipe sizes above the flue collar
Correct Answer: B — It must be designed for positive pressure applications
The code is direct: when a mechanical forced draft system creates positive pressure in the vent, the entire venting system must be designed for that condition. Standard vent material is not rated for positive pressure. The other options describe requirements that don't exist in the code.

The passing score on the real exam is a scaled score of 70 — the number of correct answers that converts to 70 varies slightly by exam form, so aim well above 70% on practice.
Your first practice score is a diagnostic. Don't treat it as a verdict. Most people underperform their first time through because the question format is unfamiliar and the time pressure is new. What your first score tells you is which topics need work, not whether you'll pass.
Use the topic-by-topic breakdown after each attempt. If you're dropping points on Plumbing Systems Installation, that's 21 real exam questions at risk. If Safety-Related Issues is weak, that's another 15. Fix the heaviest topics first — that's where your score grows fastest.
Scoring in the 70–75% range on practice usually means you're too close to the line. A few bad questions on exam day — unusual wording, an unfamiliar table — can pull you under. Aim for consistent 80%+ on practice before you sit for the real thing. The full 476 question pool means you can take multiple unique attempts to track whether your score is genuinely improving or you're just memorizing one set of questions.
Gas pipe sizing is the most common calculation trap. Candidates convert Btuh to cfh incorrectly — or skip the conversion entirely — then pull the wrong row from Table 402.4(2). Always convert first, always round the run length up to the next table row.
Wrong code section for the situation. The exam draws from both the IPC and the IFGC, plus Georgia state amendments. Knowing a rule in general isn't enough — you need to know which document it comes from and whether a Georgia amendment overrides it.
Misidentifying valid grounds for permit appeals or complaints. These questions look straightforward but candidates overthink them. Know exactly what the statute says is valid.
Test pressure and gauge requirements. In the System Testing section, candidates mix up which test applies to which system and what pressure increments are required. Air versus hydrostatic, peppermint versus smoke — these are not interchangeable.
Running out of time on Installation and Safety. Together, those two topics are 36 questions. At 300 minutes for 100 questions, your average is 3 minutes per question — but calculation-heavy installation questions eat into that budget fast. Practice under the clock.
Offset calculations using wrong constants. If you use the wrong multiplier for the fitting angle, the whole calculation is wrong. Know your 45°, 22½°, and 60° constants cold before exam day.
