Georgia Journeyman Plumber Exam Practice Exam Guide
What's on the exam
Questions per topic, out of 100The Georgia Journeyman Plumber Exam is an open book, four-option multiple-choice test built on nine outline topics: general laws, regulations, work planning, pipe cutting and joining, systems installation, system testing, maintenance and repair, safety, and trade calculations. Installation, regulations, maintenance and safety carry the heaviest item counts, so that is where study time pays.
Two ways to practice here:
- Free practice exam — 10 questions per attempt, retake it as often as you like.
- Full practice exam — 100 questions, on a clock set to 5 hours, drawn fresh from our question bank on every attempt, so repeat sittings do not repeat the same set.
Work the full version with your code books open, exactly as you will sit the real thing. Time pressure and book-handling speed are part of what you are training.
Comply with General Laws 5 items
Georgia licensing statutes, reproduced in the NASCLA guide appendices. Verified questions cover the division director's duty to advise a complainant of a pending complaint's status on request (NASCLA Georgia CILB Manual, Appendix E — O.C.G.A. § 43-1-19(h)(5)); the ten-day felony notification duty (Appendix E — O.C.G.A. § 43-1-27); mandatory revocation on a second controlled-substance conviction (Appendix E — O.C.G.A. § 16-13-111); and where the business registration number must appear — vehicles, advertising, invoices and proposals (Appendix E — O.C.G.A. § 43-14-9).
Comply with Regulations 15 items
Our verified questions here lean on combustion air and the Georgia amendments. Expect the 50 cubic feet per 1,000 Btu/h standard method (IFGC 2024, Section 304.5.1), the 100-square-inch minimum opening for combining spaces (Section 304.5.3.1), the 0.60 ACH ceiling on infiltration rate (Section 304.5.2), assumed louver free area of 25 percent wood / 75 percent metal (Section 304.10), and appliance heights in garages (Sections 305.3, 305.4). Georgia items test the high-efficiency fixture waiver conditions (Section 301.1.2), boiler thresholds, and reinspection authority (Section 300.6).
Work Planning/Organizing 7 items
Figure-reading: drainage isometrics and branch diagrams where you total the printed drainage fixture units and size a segment from a table. Practice items sum branch loads to a stack total, treat a bathroom group as one unit rather than separate fixtures (IPC 2021 — Table 709.1), size a stack on accumulated connected load (IPC 2021 — Table 710.1(2)), and pick the smallest building drain size rated for the load in the correct slope column (IPC 2021 — Table 710.1(1)).
Perform Pipe Cutting and Joining Activities 10 items
Material selection and grade math. Type K copper for underground and interior water service, Type DWV for drainage, waste and vent (Mathematics for Plumbers and Pipefitters, Pages 42-43 (Unit 9 - Copper Tubing); Page 42-44 (Units 9-10)). Grade questions apply Drop = grade × run for runs at ¼ inch and ¹⁄₃₂ inch per foot (Page 123-124 (Unit 32); Page 123-125 (Unit 32)), convert a 1 percent grade to roughly ⅛ inch per foot (Page 123 (Unit 32)), and measure sewer elevations to the invert (Page 129 (Unit 34)).
Perform Plumbing Systems Installation Activities 21 items
The largest topic. Its outline spans water supply, drainage and gas piping; our verified questions here center on gas piping. Sizing principles: supply each inlet at the minimum pressure the appliance requires (IFGC 2024, Section 402.1), total the maximum inputs (Section 402.2), use tables, manufacturer tables or approved engineering methods (Section 402.3), then read capacity from Table 402.4(2) and the longest-length method. Also outdoor combustion air openings (Sections 304.6.1, 304.6.2), appliance support at grade (Section 305.7), support spacing (Table 415.1), sauna thermostats (Section 615.6) and oxygen-depletion shutoff (Section 621.6).
Perform System Testing Activities 7 items
Gas test procedure numbers. Questions ask for the 3 psig floor when 1½ times working pressure falls short (IFGC 2024, Section 406.4.1), the gauge-range rule that the top of the scale be no more than five times test pressure (Section 406.4), and the 10-minute minimum duration for a single-family dwelling system (Section 406.4.2). One item applies the altitude adjustment for installations above 2,000 feet (IFGC 2024, Section 402.2).
Perform Maintenance and Repair Activities 15 items
Service-call scenarios. Sediment traps and the appliances exempted from them (IFGC 2024, Section 408.4); disconnecting and capping appliances rated below test pressure rather than closing a valve (Sections 406.3.3 and 406.3.4); the capped tee not less than 10 pipe diameters downstream of an MP regulator (Section 410.2); overpressure limited to 2 psi at each appliance designed for 14 inches w.c. or less (Section 416.2.1); 18 AWG yellow tracer wire (Section 404.17.3); and the 6-foot, one-connector limit with the rigid-pipe exception (Section 411.1.3.1).
Safety-related Issues 15 items
Testing, purging and personal safety. Purging stops at 90 percent fuel gas by volume (IFGC 2024, Section 406.7.1.3); outdoor purging is triggered above 2 psig design pressure (Sections 406.7.1 and 406.7.2); a three-way valve serves as backflow protection for standby gas (Section 414.2); hangers conform to MSS SP-58 (Section 407.2). Water-heater safety asks the T&P valve location within 6 inches of the top (Plumbing Technology: Design and Installation, Chapter 13: Water Heater Devices — Relief Valves), and 811 calls route to a local One Call Center.
Calculate the following during installation and service: offset, volume, area, pressure, depth, circumference, radius, weight, etc. 5 items
Applied arithmetic plus material judgment. CPVC over PVC at 120°F and higher (Mathematics for Plumbers and Pipefitters, Pages 46-47 (Unit 11 - Plastic Pipe)); Schedule 40 PVC for DWV (Page 47 (Unit 11)); elevation along a drain using ⅛ inch ≈ 0.01 foot per foot of run (Page 128 (Unit 33)); and why a DWV tee wye installed upside down reverses the built-in grade (Page 83 (Unit 23)).
Sample 1 — Perform Plumbing Systems Installation Activities
Question: A sewage ejector is being selected for a below-grade restroom that includes two water closets. Other than a grinder unit or a macerating assembly, the ejector must be capable of handling spherical solids with a diameter of up to and including ___.
- A. 3/4 inch
- B. 2 inches
- C. 1 1/4 inches
- D. 1/2 inch
Correct Answer: B
Pumps or ejectors receiving water closet discharge must pass spherical solids up to and including 2 inches. The distractors are real numbers from the same rule used the wrong way: 1/2 inch is the solids size for pumps not receiving water closet discharge, while 3/4 inch and 1 1/4 inches are minimum discharge openings for macerating assemblies and grinder pumps. Read whether the question asks for solids capability or discharge opening size. Citation: International Plumbing Code 2024, Section 712.4.2.
Sample 2 — Comply with Regulations
Question: You obtained a plumbing permit and commenced the work, but the owner's financing collapsed and the job sat suspended for 14 months. The owner now wants to finish using the same unchanged construction documents. What is required before the work may recommence?
- A. Reinstatement of the original permit upon reinspection
- B. A new permit at the full fee for such work
- C. A new permit at one-half the new permit fee
- D. An extension granted in writing by the code official
Correct Answer: B
A permit becomes null and void when work is suspended or abandoned for 180 days. The half-fee permit is available only when the construction documents are unchanged and the suspension has not exceeded one year. Here both conditions must be met and the 14-month gap breaks the second, so a new permit at the full amount is required. Track the two time limits separately: 180 days voids the permit, one year closes the reduced-fee door. Citation: International Plumbing Code 2024, Section 105.5.3.
Sample 3 — Perform Maintenance and Repair Activities
Question: You are servicing a combination potable water heating and space heating system in which the space heating loop requires water at 160°F. What must be provided to protect the potable hot water distribution system?
- A. An ASSE 1017 valve limiting to 140°F
- B. An ASSE 1016 valve limiting to 120°F
- C. An ASSE 1084 heater limiting to 130°F
- D. An ASSE 1070 device set at 110°F
Correct Answer: A
Where a combination potable water heating and space heating system needs water above 140°F for the heating loop, a temperature-actuated mixing valve complying with ASSE 1017 must limit the water supplied to the potable hot water distribution system to 140°F or less, and potability must be maintained throughout the system. The wrong options pair plausible ASSE numbers with plausible temperatures — memorize the standard and the temperature as a pair. Citation: International Plumbing Code 2024, Section 501.2.
The real exam requires a scaled score of 70, and a scaled score is not a simple count of correct answers — the raw number needed moves with the form. Treat your practice percentage as a direction indicator, not a prediction.
Your first full attempt is a diagnostic. Take it cold, open book, on the clock, and read the topic breakdown before you read the total. A 60 percent overall with a 30 percent showing in Perform Plumbing Systems Installation Activities is a different study plan than the same 60 percent spread evenly.
Weight your review by outline item counts. Installation (21 items), Comply with Regulations (15), Perform Maintenance and Repair Activities (15) and Safety-related Issues (15) account for most of the scored content; a ten-point gain in one of those is worth at least three times the same gain in a 5-item topic. Fix the heavy topics first, then sweep the light ones.
Retake the full practice exam after each round of review. Because every attempt draws fresh, a rising score reflects knowledge rather than memorized items. Also track how long book lookups take — if a search runs past a minute, keep drilling that table until you can find it quickly.
Two deadlines in one permit rule. In Comply with Regulations, the permit item (International Plumbing Code 2024, Section 105.5.3) offers the half-fee answer to anyone who remembers only the 180-day void. The reduced fee also requires that the suspension not exceed one year. Read the elapsed time in the stem before choosing.
Numbers from the same table used for the wrong thing. The ejector item (International Plumbing Code 2024, Section 712.4.2) stocks its wrong options with grinder and macerating discharge-opening sizes. Combustion air items do the same, swapping 25 percent wood and 75 percent metal louver free areas (International Fuel Gas Code (IFGC) 2024, Section 304.10). Match the number to the exact thing being asked.
Skipping the floor value in gas testing. Candidates compute 1½ times the working pressure and pick 1.5 psig. Section 406.4.1 sets a 3 psig minimum that governs whenever the multiplication lands lower (International Fuel Gas Code 2024, Section 406.4.1). The same pattern appears in duration: a single-family dwelling is 10 minutes regardless of a pipe volume that would otherwise call for a half hour (Section 406.4.2).
Closing a valve instead of disconnecting. In Perform Maintenance and Repair Activities, appliances rated below the test pressure must be disconnected and their outlets capped; closing the individual shutoff valve is permitted only for appliances rated at or above the test pressure (International Fuel Gas Code 2024, Sections 406.3.3 and 406.3.4).
Losing the clock in the code books. You get 5 hours for 120 questions (100 scored, 20 unscored), which is about 2 minutes 30 seconds per question. Open book rewards familiarity, not reading. If a question needs a table you cannot find in about a minute, flag it and move.
| Questions | 120 questions (100 scored, 20 unscored) |
| Time limit | 5 hours |
| Passing score | a scaled score of 70 |
| Books in the exam room | Open book |
- Results are given as a printed score report showing 'pass' or 'did not pass' with the final scaled score, plus content-area subscores for failing candidates.
- A failing candidate must retake the whole examination, and after two failures must complete a Board approved review course before being admitted to a third examination.
