Local Licensing • Casper & Cheyenne • ICC G28 Journeyman Plumber with Gas • 70 Questions • 3 Hours • 2018 IPC & IFGC
Wyoming Journeyman Plumber Contractor Exam Prep starts with a detail that surprises plenty of experienced tradespeople: Wyoming does not operate one statewide journeyman plumber licensing exam. Cities and other local jurisdictions set the rules for the plumbing work they regulate. Casper and Cheyenne are two important examples, and their application procedures are not identical. That is why your first study assignment should be a phone call or a visit to the building department where you intend to work. It is not especially exciting homework, but neither is preparing for the wrong test for six weeks.
The phrase “Wyoming Journeyman Plumber” is useful when searching for training, but it is not a promise that one credential covers the entire state. A local journeyman credential is generally for a skilled worker performing plumbing duties within the permission and supervision rules of the local authority. A plumbing contracting company can have a separate license and master-plumber or qualified-supervisor requirements. The journeyman passing an examination does not automatically authorize that person to start an independent plumbing business.
The City of Cheyenne contractor application page lists individual Class C-1 Plumbing Journeyman applications and explains that candidates for tested journeyman licenses must provide their experience information and the applicable examination result. The Contractor Exam Preps Wyoming overview also lists the Casper Journeyman Plumber with Gas classification associated with the ICC G28 examination. Those listings make a helpful starting point, but always ask the city whether the named exam and edition still apply to your specific application.
For candidates whose local licensing authority accepts or requires ICC G28, the June 2026 National Contractor/Trades bulletin identifies 70 multiple-choice questions, a three-hour limit and open-book testing. The bulletin shows a 70 percent exam passing standard, equivalent to 49 correct answers out of 70. That is the ICC examination rule, not a declaration that every Wyoming town applies the same threshold to its licensing decisions. In particular, Casper has published local application documents referring to a 75 percent passing requirement. Resolve any difference directly with Casper before scheduling.
ICC G28 uses the 2018 International Plumbing Code and the 2018 International Fuel Gas Code as its named examination references. One book deals mainly with plumbing fixtures, drinking water, drainage, vents and related installation rules. The other addresses fuel-gas piping, appliance connections, combustion air and venting systems. Candidates must be ready to move between the two books. A gas-fired water heater can send you looking in both, which makes good reference organization more valuable than a stack of colorful sticky notes.
The ICC June 2026 examination bulletin publishes eight content categories, including Administration and General Regulations, Plumbing Fixtures, Water Supply and Distribution, Sanitary Drainage, Plumbing Vent Requirements, Traps, Interceptors and Separators, Storm Drainage, and Gas Piping. This outline belongs to the G28 exam. A different local test, or even a similarly named ICC plumbing exam without gas, may use a different outline, time limit or edition. Match the test identifier on your appointment confirmation rather than relying on the word “journeyman” alone.
Open book sounds friendly. It is, until you discover that a three-hour exam gives about two minutes and thirty-four seconds per question. If you have to read an entire chapter every time the test mentions a water heater, that clock will turn into a dripping faucet you cannot fix. The strongest candidates practice locating a definition, identifying a chapter, reading the correct table and checking the exception before deciding on an answer. Reading every page cover to cover is not the same skill as finding a rule quickly.
Build two kinds of knowledge: field understanding and written-code understanding. Field experience may tell you how a trap, vent or water line works. The exam may ask what the adopted reference actually requires in a certain configuration. Treat those as related but separate skills. Practice identifying the system in a question, checking the edition of the code, and confirming the relevant section. A rule you remember from a newer code or another city may not match the exact reference used for G28.
Administration and General Regulations accounts for 34 percent of the published outline. It covers code definitions, installation rules, materials, testing and plan reading. It is the largest category, so learn the parts of the books that help you navigate all the other topics. Gas Piping follows at 19 percent and includes piping distribution, combustion air and fuel-burning appliance connections. Together, those two areas represent 53 percent of the test outline. That does not make the other subjects optional, but it does make study priorities easier to set.
Plumbing Fixtures and Water Supply and Distribution each represent 11 percent. Sanitary Drainage carries 9 percent. Plumbing Vent Requirements and Traps, Interceptors and Separators each carry 7 percent, while Storm Drainage carries 2 percent. These percentages add to 100. They are official weights, not exact published question counts in each category. Keep your practice tests broad and use the weighting chart later in this article to decide where additional study time will pay off.
A good plumbing study session connects systems together. Start with clean water entering a building through the service line. Follow the branch piping to a fixture, then imagine where the used water goes. The trap forms a seal. The drainage piping moves waste. The venting system helps preserve trap seals and allows the system to operate correctly. Add a fuel-fired appliance and you also have gas supply, combustion air and venting concerns. Seeing the whole route makes separate code chapters feel more like one real building.
Casper's published 2026 plumbing and mechanical application instructions describe a recognized apprenticeship completion certificate or the equivalent of four years of experience in a City of Casper licensed plumbing shop for a journeyman applicant, along with proof of successful testing. That requirement is about local eligibility, not simply knowing enough answers to pass an ICC test. Ask whether other qualifying work or a credential from another jurisdiction can be considered, and get instructions directly from the city's current Community Development staff.
Cheyenne's contractor application instructions distinguish company licensing from individual journeyman and qualified-supervisor licensing. The city asks tested journeyman and master applicants to attend a licensing board meeting and provide detailed hands-on experience information. Its Class C-1 plumbing application list includes master-and-contractor, journeyman and apprentice categories. A worker who wants to open a plumbing company should not buy a journeyman course and assume that the business application is already handled. The people, paperwork and responsibilities are different.
A city may also require background information, trade experience documents, licensing fees, insurance records, worker compensation documentation, or business-registration details depending on the applicant and license type. Do not copy a fee from another municipality. Do not assume that one city card automatically transfers to another. If you work in several communities, make a simple spreadsheet with the credential, renewal date, code edition and permit office for each. Yes, it is another spreadsheet. This one might actually save you money.
ContractorExamPreps.com sells a Journeyman Plumber Exam Prep Package based on the 2021 IPC with a code book, quick-reference tabs and a journeyman study guide. It also offers a 2021 IPC Journeyman Plumber Exam Study Guide for practice questions and general plumbing review. These can help build skills, but the 2021 IPC is not the 2018 IPC specified in the June 2026 G28 bulletin. Do not present a newer edition at the test center as an automatic replacement for the listed reference.
Candidates who want a broader learning setup can also review the Journeyman Plumber Ultimate Exam Prep Package and compare its stated components. For the ICC G28 appointment, confirm that you have the correct 2018 IPC and 2018 IFGC and that your tabs, highlighting and any markings comply with ICC and Pearson VUE policies. Product editions, store stock and testing-center allowances may change, so match the current examination catalog before making your purchase. Studying with 2021 material can be supplemental, but your final open-book drills should use the actual authorized edition.
Start with an hour-long setup session. Identify the city, locate the current application, write down the exact exam ID and obtain the authorized references. Then set six weeks of manageable study blocks. In week one, review code definitions, applications and the G28 outline. In week two, cover fixtures and water supply. Week three is for drainage, traps and venting. Week four focuses on the fuel-gas reference. Week five mixes plan reading, tests and tables. Week six is timed practice and application readiness.
Keep each study session active. Answer ten questions, locate the supporting code sections, and explain the rule aloud in plain language. If you miss a question, note whether the mistake came from the plumbing concept, the wrong book, a calculation, an exception or wasted search time. The reason matters. A missed question on a subject you already understand may simply call for better code navigation; a missed pressure or sizing question may require stronger math review. Repair the weakness, not just the score.
You can adapt the six-week schedule to rotating shifts or seasonal workloads. A plumber may have a full day of service calls, a frozen line to repair and very little interest in reading code at night. Short daily sessions can still move the needle. Spend 20 minutes on definitions during one break, 30 minutes on drainage before work and one longer session on the weekend. Consistency wins more often than a heroic last-minute cram session fueled by terrible coffee.
The ICC bulletin describes Pearson VUE as the exam-delivery partner for the National Contractor/Trades exams. Confirm your approved exam, identification requirements, testing location, permitted reference materials and rescheduling rules before the appointment. Practice pacing 70 questions across 180 minutes, leaving time to revisit difficult calculations and reference searches. If your city uses a different examination, use that provider's instructions instead. A clear registration plan is more useful than memorizing the number on an old exam-prep advertisement.
After passing, complete the local licensing application and any board review or required experience verification. ICC administers an exam; it does not issue your Cheyenne or Casper plumbing license. Do not treat a score sheet as independent authority to advertise plumbing contracting services. Check worker status, supervision, permits and separate business requirements with the local authority. This matters especially when moving from employee-level journeyman work toward becoming a master plumber or owning a contracting company.
Use this guide as a map rather than a substitute for official decisions. The detailed sections below show the G28 topic weights, explain Wyoming's local licensing model, compare the 2018 exam references with newer study books, and provide an exam-day checklist. Verify the latest regulations with Casper Community Development, Cheyenne Building Safety, and ICC Contractor/Trades testing whenever the details affect your eligibility, permitted work or appointment. Then use the Contractor Exam Preps resources to study efficiently.
Important Wyoming Journeyman Plumber Licensing Update: Wyoming does not issue a single statewide journeyman plumber license. Casper and Cheyenne regulate plumbing locally. The ICC G28 Journeyman Plumber with Gas exam has 70 questions, 3 hours, and a 70% ICC exam passing standard with 2018 IPC and 2018 IFGC references. Casper has separately published a 75% local testing requirement, so confirm acceptance and local standards with the city before you register. Review the current ICC bulletin and Cheyenne’s official application requirements.
A journeyman plumber is a skilled plumbing worker who performs installation, service, repair and related tasks within the scope allowed by the local licensing jurisdiction. In Wyoming, there is no single statewide plumbing credential issued through a state plumbing board. Your authority to work depends on municipal or county requirements, the job location and whether the work requires permits or supervision.
In Cheyenne, plumbing is part of the Class C-1 trade licensing system. Individual journeyman credentials and plumbing company licenses are listed separately. Casper also licenses journeyman and master plumbers and regulates plumbing companies. A journeyman credential does not automatically replace the master plumber or contractor qualification that a business may need.
Candidates preparing for ICC G28 should understand basic potable water supply, drainage, venting, fixtures, gas piping, testing procedures, material requirements and plan-reading skills. The examination is open book under ICC conditions, but its two approved 2018 references require real practice to use efficiently.
Use the City of Cheyenne license applications and the City of Casper website to find the authority for your project location. The name of the trade test is only one part of the local licensing decision.
These are two local examples. There is no uniform statewide journeyman plumber application. The current local office controls eligibility, acceptance of exam results and fees.

The percentages below come from the ICC June 2026 G28 outline and total 100%. They are published percentages, not individual exact question counts.
General installation requirements, materials, definitions, plan reading and testing methods. Learn the layout of both books before drilling specific chapter tables. Practice locating sections and tables in the approved 2018 codebooks, then explain why the correct answer applies to the question.
Water heaters, toilets, urinals, tubs, showers, sinks, lavatories, clearances and associated installation rules. Practice locating sections and tables in the approved 2018 codebooks, then explain why the correct answer applies to the question.
Service lines, water pressure, supply sizing, cross-connection and backflow protection, and system piping. Practice locating sections and tables in the approved 2018 codebooks, then explain why the correct answer applies to the question.
Building drains, sizing, proper drainage connections, sumps, ejectors, indirect waste and special waste systems. Practice locating sections and tables in the approved 2018 codebooks, then explain why the correct answer applies to the question.
Vent connections, required arrangement, grades, developed lengths and terminals. Practice locating sections and tables in the approved 2018 codebooks, then explain why the correct answer applies to the question.
Trap installation, seal protection, cleanouts, interceptors and separators. Practice locating sections and tables in the approved 2018 codebooks, then explain why the correct answer applies to the question.
Roof and storm-drainage routing and sizing principles. Practice locating sections and tables in the approved 2018 codebooks, then explain why the correct answer applies to the question.
Service and distribution pipe sizing, gas appliances, combustion air, appliance vents and connectors. Practice locating sections and tables in the approved 2018 codebooks, then explain why the correct answer applies to the question.
The G28 exam is a specific ICC national examination. Other plumbing trade exams may weight these subjects differently, so make sure your license authority accepts G28.
Prepare for the exam your local licensing office will actually accept. If you are taking ICC G28, label two approved 2018 references separately: one for plumbing and one for gas. Build a weekly score log, time your code lookups and study across all eight categories instead of reading random chapters.
Give extra attention to Administration and General Regulations and Gas Piping, which account for 53% together. Then rotate through water distribution, fixtures, drainage, venting, traps and storm drainage. Practice using figures, tables and exceptions, and check a rule in the correct book instead of relying only on field memory.
Use the Journeyman Plumber Study Guide or the 2021 IPC practice package from Contractor Exam Preps for supplemental questions, but match final exam-book practice to the 2018 G28 references.
Use this simplified diagram to connect water supply, fixtures, traps, drainage, venting and gas systems. It is an exam study aid, not a design or installation drawing.
For a test question, start by identifying the system, then the book, then the exact section or table.
Identify who licenses the work site. Wyoming plumbing licenses are local, not statewide.
Ask whether you need individual journeyman, apprentice, master or a separate business contractor license.
Gather apprenticeship completion, hands-on work history, employer letters and any city forms.
Confirm whether G28 Journeyman Plumber with Gas is required or accepted and verify local passing rules.
For G28, verify 2018 IPC and 2018 IFGC and their permitted markings.
Cover all eight official subjects and practice with a clock.
Follow ICC/Pearson VUE check-in and local board steps where required.
Submit passing results and records; wait for license approval before work requiring a credential.
Published topic percentages from the ICC G28 outline. Bars show percentages of the full exam, not a guarantee of an exact number of questions per subject.
General Regulations (34%) and Gas Piping (19%) are the two largest areas, totaling 53%. Keep all eight on your study schedule.
The official G28 ICC bulletin determines which books are approved for exam day. Newer store resources can be used for learning, but they are not automatic substitutes.
| Reference | Edition or Product | How It Helps |
|---|---|---|
| 2018 International Plumbing Code | Official G28 reference | Plumbing regulations, fixtures, water, drainage and vent systems. |
| 2018 International Fuel Gas Code | Official G28 reference | Gas piping, combustion air, appliance installation and venting. |
| Journeyman Plumber Exam Study Guide | Contractor Exam Preps, 2021 IPC based | Supplemental questions and code comprehension; not listed as G28 official reference. |
| Journeyman Plumber Exam Prep Package | 2021 IPC plus tabs and study guide | Supplemental practice and navigation, edition differs from 2018 G28 books. |
| Journeyman Ultimate Prep Package | 2021 IPC based | Broader study resources; verify inclusions before buying. |
| ICC National Contractor/Trades Bulletin | June 2026 | Exam topics, scoring, approved references, rules and registration. |
Use 2018 editions for your final G28 reference practice unless ICC formally updates or authorizes alternatives. When the local jurisdiction specifies a different exam, use its exact reference list.
Strong open-book preparation combines trade understanding with accurate, fast reference navigation. These habits reduce avoidable mistakes when you work under a three-hour limit.
Your goal is not to remember the page number of every rule. It is to know how to find and apply a correct code requirement quickly.
An individual journeyman plumber may be able to install, repair, service and maintain plumbing systems within the local license scope. Typical tasks can involve fixtures, water distribution, drainage, vent piping, plumbing connections and code-compliant repair work. Work involving gas may have additional classification, testing or supervision requirements. The exact permission comes from the city or county, not from the label on a commercial study guide.
Casper describes journeyman work as plumbing tasks performed as an employee of a plumbing contractor. Cheyenne similarly separates an individual Class C-1 plumbing credential from a company contractor license. Contractors often need a master plumber or qualified supervisor to meet business-level rules. Verify permits, inspections, worker classifications and job-site supervision before accepting a project.
If the project spans a city boundary or requires licenses in several communities, contact each relevant authority. A plumbing card that is useful in one Wyoming city should not be assumed valid in another without confirmation.
Similar titles do not give the same legal authority. Confirm the local category before you schedule the trade test.
| Classification | Typical Focus | Important Difference |
|---|---|---|
| Journeyman Plumber | Individual plumbing trade work | Subject to city scope and experience rules. |
| Apprentice Plumber | Training and supervised plumbing work | Requires local registration where applicable. |
| Master Plumber | Higher responsibility and trade qualification | May qualify a plumbing company under city rules. |
| Plumbing Contractor | Licensed business offering plumbing services | Separate insurance, company and qualified-person requirements. |
| Journeyman Plumber with Gas (G28) | National ICC trade examination including fuel gas | Exam result only; local license authority decides acceptance. |
| Journeyman Plumber (G25) | Different ICC plumbing examination | Different references and timing than G28. |
| Mechanical / HVAC | Heating, ventilation and mechanical systems | Separate local classifications and approved tests. |
Trade exam pathway
Best for: Candidates directed to G28 by local officials.
Municipal credential
Best for: Workers seeking local journeyman status.
2021 IPC educational materials
Best for: Students needing general practice before checking approved code editions.
Short daily reviews plus timed full-length practice make studying more realistic for working tradespeople.
ICC G28 is demanding because it combines plumbing and fuel-gas questions in one timed exam. Someone with years of experience repairing drainage problems may be less comfortable with combustion-air provisions or gas-pipe sizing. Another candidate may know gas appliances but need stronger practice with venting, drainage traps or water-distribution tables. The questions cover real trade knowledge and accurate code reading.
The ICC bulletin sets 70 questions in three hours. The 70% exam threshold means 49 correct responses, but local acceptance requirements should be verified separately. The largest G28 categories are General Regulations at 34% and Gas Piping at 19%; however, passing requires reliable coverage across the eight areas.
Open-book testing is not a shortcut. You need to recognize which of two books applies to a question, locate the right section, interpret exceptions and answer before your time runs out. Test readiness is best measured by timed mixed practice and fewer repeat mistakes, not by how many pages you highlighted.
Review ICC and Pearson VUE instructions shortly before the appointment. Local licensing paperwork is separate from testing-center admission.
The following store products cover journeyman plumbing skills, but their 2021 IPC editions are supplemental for candidates testing on ICC G28, which lists 2018 IPC and IFGC. Check edition and exact inclusions on the product page.

Wyoming Journeyman Plumber Contractor Exam Prep works best when you separate three different questions: where will you work, which credential does that local government require, and which examination has been accepted for that credential? Wyoming does not operate a single statewide journeyman plumbing board. That makes the city or county your first important source of information. Casper and Cheyenne have published plumbing licensing programs, but their applications are not identical. A person who is eligible in one community may need additional paperwork or approval somewhere else. Verify the jurisdiction before ordering books or making a test appointment.
For an applicant directed to the ICC G28 National Standard Journeyman Plumber with Gas examination, the June 2026 bulletin is a useful road map. It identifies 70 multiple-choice questions, three hours, open-book testing and an ICC standard of 70 percent. That makes 49 correct answers the basic ICC exam target. However, a municipality can apply its own licensing conditions. Casper has published application language referring to a 75 percent testing minimum, while Cheyenne has individual application and board-review rules. Never assume the ICC score requirement is the only condition for getting your local license.
The G28 trade content covers eight categories. Administration and General Regulations carries the largest share at 34 percent and includes material rules, installation requirements, definitions, testing and plan reading. Gas Piping accounts for 19 percent. The remaining subjects are plumbing fixtures, water distribution, sanitary drainage, plumbing vents, traps and interceptors, and storm drainage. Because gas and general regulations together represent more than half of the outline, they deserve regular practice, but skipping the smaller topics is risky. A well-prepared candidate should be able to explain the basic operation of an entire plumbing system and locate the code provision that supports a decision.
Book editions deserve special care. G28 currently lists the 2018 International Plumbing Code and the 2018 International Fuel Gas Code. Contractor Exam Preps offers helpful journeyman study resources based on the 2021 IPC, including a stand-alone guide, a package with tabs and a larger ultimate package. Those materials can support general plumbing understanding, but a newer code edition is not automatically an approved examination reference. Practice with the exact listed books for your final timed sessions, and confirm permitted tabs or markings before test day.
A six-week routine can make preparation manageable. Begin with licensing rules and code navigation. Study fixtures and water distribution next, followed by drainage, traps and vents. Give fuel-gas systems their own focused week. Use the final weeks for general regulations, diagrams, calculations, mixed questions and full-length practice. Record why an answer was wrong, then find the correct explanation in the authorized reference. You will learn more by fixing a confusing concept than by repeatedly guessing the same question.
Finally, remember that passing an exam is not a plumber license or a business license. Maintain your experience records, complete local applications, attend required board meetings and verify the qualifications for any company you intend to operate. Keep your work within the legal scope of the approved credential. With the right local guidance, accurate codebooks and steady study habits, Wyoming journeyman plumber preparation can become a clear series of tasks rather than a guessing game. The pipes should be complicated enough without making the paperwork another leak to chase.
Wyoming Journeyman Plumber Contractor Exam Prep is for people who want to prepare for journeyman-level plumbing work in Wyoming. The first important fact is that the state does not have one statewide journeyman plumber license. Local governments control plumbing credentials where licensing is required. Casper and Cheyenne are two examples. Their rules can differ, so you must check with the city or county where you plan to work.
A journeyman plumber is an individual skilled worker. That is not the same as a plumbing contractor company. A city may require a contractor license and a master plumber or qualified supervisor before a company can offer certain work. If your goal is to open your own plumbing business, ask about both personal trade licensing and the company application. A good exam score does not erase those other requirements.
One test used for local journeyman plumbing licensing is the ICC G28 Journeyman Plumber with Gas examination. The June 2026 ICC bulletin describes a test with 70 multiple-choice questions and three hours of testing time. The exam is open book, subject to the ICC rules. The ICC passing standard is 70 percent, meaning at least 49 correct answers on a 70-question exam. However, local licensing requirements can differ. Casper has published a separate 75 percent minimum in local application material. Ask the municipality what score and examination it accepts.
The G28 exam uses two main books: the 2018 International Plumbing Code and the 2018 International Fuel Gas Code. The plumbing book covers fixtures, water supply, sanitary drainage, vents, traps and other plumbing systems. The fuel-gas book covers gas piping, appliances, combustion air and related venting. Learn how to use the index, contents, definitions, chapter headings and tables. The exam clock moves quickly, so simply bringing the books is not enough.
The official G28 outline has eight study areas. General Regulations is the largest, at 34 percent. Gas Piping follows at 19 percent. Plumbing Fixtures and Water Supply and Distribution are each 11 percent. Sanitary Drainage is 9 percent. Plumbing Vent Requirements are 7 percent, and Traps, Interceptors and Separators are also 7 percent. Storm Drainage makes up 2 percent. Study every subject and spend extra time on topics where your practice scores are weak.
ContractorExamPreps.com has a Journeyman Plumber Exam Study Guide, a Journeyman Plumber Exam Prep Package and an Ultimate Package. These are useful study resources, but the store products discussed here use the 2021 IPC. This is different from the 2018 IPC listed for ICC G28. You can use general study questions to learn plumbing ideas, but use the correct exam editions for final reference practice. Before buying, compare current product contents with official ICC requirements.
A six-week study plan gives you time to learn the material without rushing. Week one is for local licensing rules and book organization. Week two covers fixtures and water supply. Week three is for drainage, traps and venting. Week four is for fuel-gas piping and appliances. Week five combines plan reading, regulations, tables and calculations. Week six is for full timed practice exams and final checks. Review missed questions and practice finding answers in the correct book.
On exam day, bring only the identification and reference materials allowed by the testing provider. Confirm the exact exam title, appointment time, location and rules in advance. When you pass, complete the remaining city application requirements before doing work that requires a license. The best route is simple: verify locally, study the correct books, practice under a clock and get the official license approval.
