Missouri Local Plumbing Licensing • Springfield ICC W25 • Kansas City ICC 675 • 70 Questions • 180 Minutes • Open Book
Ready to move forward with your Missouri Journeyman Plumber certification? This guide covers local plumbing licensing, ICC examinations, approved reference books, plumbing fixtures, water supply, drainage, venting, fuel-gas systems, code study, and related Contractor Exam Preps materials.
Plumbers keep buildings healthy, safe, and comfortable by installing and maintaining the systems that bring water into buildings and carry wastewater away.
Every sink, shower, water heater, water closet, floor drain, and drainage stack depends on careful plumbing work.
Most people do not think about plumbing until something stops working.
When water starts dripping through the ceiling, however, plumbing suddenly becomes everyone's favorite topic!
A Journeyman Plumber generally has practical experience with plumbing installation, repair, maintenance, and code requirements.
Journeymen often work under the licensing and supervision framework established by their local jurisdiction.
They may install fixtures, connect water-supply piping, work on sanitary drainage, install vents, test systems, and troubleshoot plumbing problems.
The exact scope depends on the local credential.
One important distinction is that Missouri does not have one statewide Journeyman Plumber examination that applies identically across every city and county.
Plumbing trade qualifications and contractor licenses are generally handled through local jurisdictions.
That means a candidate in Springfield may need a different exam and different code book from someone working in Kansas City.
This difference matters before purchasing study materials.
A plumbing codebook might be excellent for one examination and the wrong reference for another.
The two published Missouri examination paths covered in this guide are the Springfield ICC Journeyman Plumber examination and the Kansas City ICC Journeyman Plumber with Gas examination.
Both currently list 70 multiple-choice questions.
Both allow three hours.
Both are listed as open-book tests.
But the subjects, references, and licensing requirements are not identical.
Springfield's published examination is called W25 Missouri (Springfield) Journeyman Plumber.
The exam is delivered through the ICC Contractor/Trades testing program using Pearson VUE.
It contains 70 multiple-choice questions.
It allows 180 minutes.
Its official reference is the 2018 International Plumbing Code.
This examination concentrates on plumbing regulations and installation requirements.
The largest category is Administration and General Regulations, representing 40% of the exam.
That is a major share of the total examination.
It covers subjects such as definitions, general installation requirements, materials, and testing.
The next largest topic is Plumbing Fixtures, at 17%.
Water Supply and Distribution represents 14%.
Sanitary Drainage accounts for 13%.
Plumbing Vent Requirements accounts for 7%.
Traps, Interceptors, and Separators also accounts for 7%.
Storm Drainage represents the remaining 2%.
Together, those seven categories make up the complete published W25 examination outline.
Springfield candidates should also pay attention to local trade certification rules.
City certification guidance described in Springfield-focused exam preparation materials calls for a minimum 75% score notification on an accepted examination.
Candidates should verify the current City requirement rather than assuming that a general ICC passing standard automatically satisfies local certification.
Springfield's Building Development Services handles the local certification process.
Applicants may need to provide experience documentation and receive approval before scheduling the required exam.
After testing, the candidate completes the remaining City certification requirements.
Kansas City's published examination is called 675 Missouri (Kansas City) Journeyman Plumber with Gas.
Like Springfield W25, it contains 70 multiple-choice questions.
It allows three hours.
The examination is open book.
However, its approved references are different.
The published Kansas City examination bulletin lists the 2018 Uniform Plumbing Code and 2018 International Fuel Gas Code.
These references cover plumbing installations and fuel-gas systems.
That second code is especially important because Kansas City's exam includes a substantial gas-piping category.
Gas Piping represents 29% of the Kansas City 675 exam.
This is its largest published subject.
Candidates may need to understand fuel-gas piping materials, pipe sizing, gas distribution, appliance connections, combustion air, and venting.
Other Kansas City exam subjects include Administration and General Regulations at 14%, Plumbing Fixtures at 11%, Water Supply and Distribution at 11%, Sanitary Drainage at 13%, Plumbing Vent Requirements at 13%, Traps and Interceptors at 8%, and Storm Drainage at 1%.
These percentages total 100% of the published Kansas City examination.
The Kansas City licensing process is administered through the City's Planning and Development Department.
The City requires individuals and businesses to follow separate qualification and contractor licensing procedures.
A Journeyman Plumber Certificate of Qualification is an individual credential.
A plumbing contractor license is the authorization for the business to perform contracting work.
Those credentials are not interchangeable.
In Kansas City, the contractor business license process may involve a qualified supervisor and additional documentation.
Applicants should review the City's published Journeyman Plumber Certificate of Qualification requirements and the current contractor licensing instructions before taking the exam.
The International Plumbing Code and Uniform Plumbing Code both regulate plumbing installations, but they are not identical publications.
They can differ in chapter organization, technical provisions, tables, terminology, and specific installation requirements.
For that reason, a candidate preparing for Springfield W25 should not automatically substitute a UPC book for the listed 2018 IPC.
A Kansas City 675 candidate should not assume that a 2018 IPC is an approved replacement for the listed 2018 UPC.
And because Kansas City includes fuel-gas subjects, candidates also need the correct 2018 International Fuel Gas Code.
This is one of the easiest mistakes to prevent before testing.
Confirm the actual examination code, then gather its approved references.
For Springfield, that means studying the 2018 International Plumbing Code.
For Kansas City, that means studying the 2018 Uniform Plumbing Code and 2018 International Fuel Gas Code.
Other Missouri jurisdictions may adopt or test on different editions.
Although the two examinations differ, they share several core plumbing subjects.
Water supply and distribution is one major subject.
Students should understand water service piping, distribution arrangements, water pressure, sizing rules, approved materials, and protection of potable water.
Backflow prevention is an important part of protecting drinking water from contamination.
Sanitary drainage is another major topic.
Drainage piping must carry wastewater away from plumbing fixtures while following code requirements for sizing, slope, installation, and testing.
Students should understand horizontal branches, building drains, cleanouts, sumps, and special waste arrangements.
Venting supports the safe operation of plumbing drainage systems.
Plumbing vents help maintain proper system pressures and protect fixture trap seals.
Candidates should review vent connections, terminals, grades, and sizing where required by the applicable code.
Fixtures and equipment are also important.
Study water closets, urinals, sinks, lavatories, bathtubs, showers, water heaters, and other specialized fixtures.
General regulations include definitions, approved materials, system testing, installation procedures, and code application.
Traps and interceptors are used to manage wastewater and help protect building occupants.
Storm drainage includes roof drainage and related rainwater disposal systems.
Kansas City applicants must add gas-piping preparation.
Fuel-gas piping systems have their own sizing, material, testing, venting, and appliance-connection requirements.
These rules should be studied using the International Fuel Gas Code edition specified by the Kansas City bulletin.
Contractor Exam Preps offers several general Journeyman Plumber study resources that may help Missouri candidates strengthen their plumbing knowledge.
The Journeyman Plumber Exam Study Guide based on the 2021 International Plumbing Code includes 750 practice questions with answer keys, plumbing mathematics, isometric drawing review, OSHA topics, and testing strategies.
It can be useful for general IPC-based review.
However, the Springfield W25 bulletin specifically lists the 2018 IPC.
The 2021 study guide is therefore a supplemental study product, not a replacement for the 2018 examination reference.
For UPC-based plumbing study, Contractor Exam Preps offers the Journeyman Plumber Exam Study Guide based on the 2021 Uniform Plumbing Code.
This publication includes 990 practice questions with answer keys, plumbing mathematics, isometric analysis, OSHA review, and trade preparation techniques.
The guide is relevant to many UPC plumbing concepts.
However, the Kansas City examination lists the 2018 UPC.
That edition difference matters during official codebook preparation.
The store also sells the Journeyman Plumber Test Success Online Course based on the 2021 Uniform Plumbing Code.
This is another supplemental resource for plumbing principles, code learning, video instruction, calculations, and practice tests.
It should not be presented as the official Kansas City 675 course.
Contractor Exam Preps maintains a Missouri Journeyman Plumber collection, a Springfield W25 collection, and a Kansas City 675 collection.
Those pages can help users navigate Missouri-related exam preparation categories.
For a directly labeled Springfield course and reference package, 1ExamPrep.com also offers W25-specific study options.
It also lists a Kansas City 675 two-book package using the 2018 UPC and 2018 IFGC.
Before buying, confirm which seller's package contains the exact approved editions and whether it is intended for your selected examination.
Start with the official local examination bulletin.
Read the test format, references, content areas, and examination rules.
Organize your study around the published topic percentages.
For Springfield, spend extra time with general regulations because they make up 40% of the examination.
For Kansas City, make gas piping a major priority because it makes up 29%.
Practice finding definitions, technical tables, conditions, and code exceptions.
Work through sample plumbing problems regularly.
Learn to recognize when a question asks about water distribution, fixture installation, drainage, vents, or another specific system.
Then locate the corresponding code requirement.
Since both published exams allow 180 minutes for 70 questions, candidates have an average of approximately 2.57 minutes per question.
That makes reference navigation important.
An open-book exam is helpful, but a codebook cannot answer a question by itself.
You still need to find the correct section before the clock runs out.
A six-week schedule can help you prepare in a balanced way.
Use the first week to confirm the exam and gather books.
Study general regulations and fixtures during the second week.
Review water supply and sanitary drainage during the third.
Focus on venting, traps, and interceptors during the fourth.
Use the fifth week for gas piping if taking Kansas City 675, or additional general regulations if taking Springfield W25.
During the final week, complete several timed practice examinations.
Review the questions you miss and locate the supporting code language.
Finally, remember that a journeyman credential does not automatically license a plumbing contracting business.
Someone may qualify as a journeyman while the company must still meet separate business licensing, supervisor, permit, and insurance requirements.
This guide covers those distinctions along with the official examination breakdowns, reference books, study strategies, a plumbing system diagram, related Contractor Exam Preps products, FAQs, and a real 1ExamPrep YouTube video.
Important Missouri Journeyman Plumber 2026 Update: Missouri does not have one statewide Journeyman Plumber exam used by every local jurisdiction. Springfield's ICC W25 exam lists 70 questions, three hours, open-book testing, and the 2018 International Plumbing Code. Its largest topic is Administration and General Regulations at 40%. Kansas City's ICC 675 Journeyman Plumber with Gas exam also lists 70 questions and three hours, but uses the 2018 Uniform Plumbing Code and 2018 International Fuel Gas Code. Its largest topic is Gas Piping at 29%. Springfield certification materials identify a local 75% score expectation; applicants should confirm the latest City standard. Journeyman qualification is not the same as a plumbing contractor business license. Verify the current local bulletin, licensing approval, and reference-book rules before testing.
A Missouri Journeyman Plumber is a plumbing tradesperson who has satisfied applicable local qualification requirements.
These may include verified experience, an approved apprenticeship pathway, an examination, and a local certification application.
The specific requirements depend on the city or county.
Journeyman plumbers install, repair, and maintain water supply, sanitary drainage, venting, fixtures, piping, and related systems within their authorized scope.
They need to know the plumbing code that applies to their work.
They also need to understand correct pipe materials, fittings, water pressure, backflow protection, fixture connections, and drainage methods.
Some local qualifications include fuel-gas systems.
Others use a separate gasfitter credential.
A journeyman certificate usually belongs to the individual.
A plumbing contractor license typically belongs to the business.
The company may need a qualified plumbing supervisor, master plumber, insurance, permits, and other licensing documents.
For example, Kansas City's contractor licensing process separates a business license, a qualified individual's Certificate of Qualification, and the contractor license for the company.
Individual trade: Journeyman Plumber.
Examples: Springfield ICC W25 and Kansas City ICC 675.

A fixture question should lead to the fixture provisions.
A water-supply question should lead to the correct distribution or sizing requirements.
A drainage question may require a table or a specific installation provision.
A Kansas City gas-piping question should direct attention to the 2018 International Fuel Gas Code.
Read code exceptions and table notes before finalizing answers.
Use the full 180-minute examination limit during practice.
A Missouri Journeyman Plumber may perform plumbing installation, repair, maintenance, and related trade work within the authorization granted by the local jurisdiction.
Common tasks include installing water distribution piping, drainage systems, vents, fixtures, and water heaters.
Journeymen may also work with traps, cleanouts, fittings, piping materials, backflow protection, and system testing.
Some jurisdictions include fuel-gas work within a plumber-with-gas qualification.
Other locations may have separate gasfitter certificates.
The work must follow applicable codes, permit rules, and supervision requirements.
In Kansas City, the Journeyman Plumber Certificate of Qualification is an individual credential for labor at the plumbing trade as an employee of a licensed plumbing contractor.
It is not the same as owning a licensed plumbing contracting business.
Individuals planning to start a plumbing company should review the master plumber, qualified supervisor, business license, and contractor registration rules for their local jurisdiction.
Individual credential: Journeyman Plumber.
Typical work: Fixtures, water supply, drainage, venting, and system testing.
Fuel gas: Depends on the specific credential and jurisdiction.
Contractor business: May require additional licensing and a qualified supervisor.
Final scope authority: Local licensing department.
| Credential | Authority | Main Difference |
|---|---|---|
| Springfield Journeyman Plumber | City of Springfield | Individual trade certification; W25 exam based on 2018 IPC. |
| Springfield Master Plumber | City of Springfield | Separate higher-level qualification; ICC W24 is a different examination. |
| Kansas City Journeyman Plumber with Gas | Kansas City | Individual qualification involving plumbing and fuel-gas systems; ICC 675 is a recognized exam. |
| Kansas City Master Plumber | Kansas City | Separate supervisory qualification with additional experience and examination requirements. |
| Plumbing Contractor Business | Local Licensing Department | Business authorization; separate from an individual's journeyman certificate. |
| Gasfitter | Local Licensing Department | May be a separate specialty qualification for fuel-gas systems. |
| Other Missouri Cities | Applicable Local Authority | May use different exams, codes, experience standards, and renewal rules. |
2018 International Plumbing Code
2018 UPC and 2018 Fuel Gas Code
Supplemental Plumbing Knowledge
Use this plan with the correct local exam blueprint and approved codebooks.
Missouri Journeyman Plumber examinations can be challenging because the questions test code application, not just memory.
A plumbing professional may have years of field experience but still need practice answering code-based multiple-choice questions.
For example, a fixture installation that works in practice may not meet every requirement of the applicable code.
Exam questions may focus on one important detail, such as the selected material, location, sizing table, testing requirement, or exception.
Springfield W25 places 40% of its weight on Administration and General Regulations.
That makes code definitions, materials, installation standards, and testing especially important.
Kansas City 675 emphasizes gas piping.
Its 29% gas category can be difficult for applicants who primarily work on water and sanitary drainage systems.
Both exams allow three hours for 70 questions.
To improve performance, practice identifying the topic before opening a reference book.
Use the correct edition and follow the current testing rules.
The Journeyman Plumber IPC Study Guide and UPC Study Guide offer supplemental practice, but they use newer 2021 code foundations.
Always prepare your official exam-room books separately according to the local 2018 reference requirements.
Contractor Exam Preps offers related plumbing study materials for candidates who want to improve plumbing knowledge, exam strategies, calculations, and practice-test skills.
The following verified store products use 2021 code editions. They are supplemental to the officially listed 2018 Missouri local exam references.

Preparing for a Missouri Journeyman Plumber examination is an important step for people who want to advance their plumbing careers and demonstrate the knowledge required by a local licensing authority.
Journeyman plumbers play an important role in maintaining safe and reliable water supply, drainage, and venting systems.
They install fixtures, connect piping, repair plumbing systems, test installations, and help protect public health.
Good plumbing work requires more than practical experience.
It also requires an understanding of code requirements, materials, system sizing, pressure, fixture connections, drainage, and proper ventilation.
One of the most important things to understand before starting exam preparation is that Missouri does not use one universal statewide Journeyman Plumber examination.
Local jurisdictions can have different examination codes, reference books, application requirements, and certification rules.
Springfield and Kansas City provide useful examples.
The Springfield ICC W25 Journeyman Plumber examination includes 70 multiple-choice questions.
Candidates receive three hours to finish.
The exam is open book, with the 2018 International Plumbing Code listed as its official reference.
The largest subject is Administration and General Regulations, accounting for 40% of the published examination.
Additional subjects include plumbing fixtures, water supply, sanitary drainage, venting, traps, interceptors, and storm drainage.
Springfield applicants should also verify the City's accepted passing-score standard and the required certification application steps.
Kansas City's ICC 675 Journeyman Plumber with Gas examination also contains 70 questions and allows three hours.
However, it uses the 2018 Uniform Plumbing Code and 2018 International Fuel Gas Code.
The Kansas City examination includes a large Gas Piping category, representing 29% of the exam.
That makes fuel-gas preparation especially important for candidates taking this version.
Study gas distribution, piping materials, sizing, appliance connections, combustion air, and venting requirements.
Both examinations also cover important plumbing knowledge such as water distribution, drainage, fixtures, and venting.
Use the official examination outline to plan your study time.
Begin with the topics that represent the largest percentages.
Then review the remaining subjects to improve your overall readiness.
Because these are open-book examinations, reference navigation is essential.
Learn how the approved codebooks are organized.
Practice identifying the subject of a question, selecting the correct chapter, locating a requirement, and checking any exceptions.
With 70 questions in 180 minutes, candidates have only about two minutes and 34 seconds for each question on average.
That is enough time for careful work, but not for reading an entire code chapter every time an unfamiliar subject appears.
Contractor Exam Preps provides supplemental plumbing study resources.
The Journeyman Plumber Exam Study Guide based on the 2021 International Plumbing Code contains 750 practice questions with answer keys.
The 2021 Uniform Plumbing Code Journeyman Plumber Study Guide contains 990 practice questions and answers.
These resources cover useful subjects such as water supply, drainage, venting, plumbing mathematics, isometric drawings, and test-taking methods.
They can help candidates practice general plumbing concepts outside the testing center.
However, these products use 2021 code foundations, while the local Missouri exam bulletins discussed here list 2018 reference editions.
Applicants should not replace the approved 2018 exam books with newer study materials unless the examination provider expressly permits that change.
Contractor Exam Preps also offers a Journeyman Plumber Test Success Online Course based on the 2021 UPC.
This option can support general plumbing knowledge and practice, but applicants should still use the current local examination bulletin as their guide.
A six-week study plan can help make preparation manageable.
Start with examination rules and reference books.
Then review general regulations, fixtures, water supply, drainage, venting, and traps.
Add fuel-gas preparation if you are taking the Kansas City 675 examination.
During the final week, complete timed practice examinations and review missed questions carefully.
Remember that a Journeyman Plumber credential is generally an individual qualification.
It does not automatically authorize someone to operate a plumbing contracting business.
A separate business license, qualified supervisor, insurance, permits, or other local requirements may apply.
Before making licensing decisions, confirm the rules with the appropriate Missouri city or county.
By choosing the correct exam path, studying the approved codebooks, practicing regularly, and using related Contractor Exam Preps resources wisely, candidates can approach Missouri Journeyman Plumber certification with a more organized plan and stronger technical knowledge.
