Indiana Plumbing Commission • PROV • 90 Questions • 180 Minutes • Open Book • State-Approved References
Ready to earn your Indiana Journeyman Plumber license? This Indiana Journeyman Plumber Contractor Exam Prep guide covers the official licensing process, plumbing experience requirements, PROV examination, approved Indiana plumbing references, drainage, venting, water supply, isometric drawings, and real study products from Contractor Exam Preps.
Indiana licenses journeyman plumbers through the Indiana Plumbing Commission, part of the Indiana Professional Licensing Agency, commonly called IPLA.
The license is an individual trade credential.
It is not the same as a separate Indiana Plumbing Contractor license.
That difference matters because journeyman plumbers and plumbing contractors have different licensing classifications and examination outlines.
The Indiana Journeyman Plumber exam is administered by PROV.
According to the official PROV Candidate Information Bulletin dated June 24, 2026, the exam contains 90 questions.
Candidates have three hours, or 180 minutes, to complete it.
It is a computer-based multiple-choice examination.
The current PROV bulletin does not specify a numeric passing percentage for the Journeyman Plumber exam.
It explains that the Indiana Plumbing Commission sets the examination eligibility process and PROV reports passing or failing results.
Instead of relying on an unverified passing percentage, candidates should confirm the current standard with the Commission or PROV.
The examination allows approved reference materials.
That is helpful because plumbing codes contain many tables, exceptions, installation requirements, and specific measurements.
However, open book does not mean every plumbing book is permitted.
Indiana has an especially important codebook requirement.
The current PROV bulletin lists the 2006 International Plumbing Code, second printing, Indiana Edition, 2012.
It also permits the 2006 International Plumbing Code or the 2006 International Plumbing Code: Code and Commentary as specified substitutes.
The examination also lists the 2012 Indiana Amendments, 675 IAC 16-1.4.
Another approved reference is A Compilation of the Indiana Code and Indiana Administrative Code, 2014.
The Indiana Plumbing Supplement may be substituted for that compilation under the published PROV rules.
These Indiana-specific materials are particularly important because state rules may modify or supplement the base plumbing code.
A student who knows only the general IPC may miss an Indiana-specific requirement.
The store sells the Indiana Journeyman Plumber Exam Book Package.
This package contains a three-book reference set based on the Indiana examination publications.
It includes the Indiana plumbing code reference, applicable amendments, and Indiana Plumbing Supplement.
This makes it a particularly relevant starting point for preparing the actual open-book examination.
Contractor Exam Preps also sells newer study packages.
One option is the 2026 Indiana Journeyman Plumber Study Guide and Online Course.
This product uses the 2024 International Plumbing Code and provides study questions, explanations, video instruction, and practice exercises.
It is useful for learning plumbing concepts and reviewing the trade.
However, it does not replace the older Indiana references currently listed as approved for PROV testing.
The store also offers an Indiana Journeyman Plumber Exam Prep Package Based on the 2021 IPC.
This is another supplemental study option.
The 2021 and 2024 IPC editions may have different language, tables, requirements, or section locations compared with the approved 2006 reference.
That is why exam-specific study should always be checked against the current PROV bulletin.
Indiana also has important eligibility requirements.
Journeyman Plumber applicants must be at least 18 years old.
One qualification pathway involves completion of an apprenticeship program approved by the Indiana Plumbing Commission.
The approved apprenticeship pathway generally involves four years of training.
Applicants must provide the required apprenticeship completion certification.
Indiana also recognizes qualifying plumbing trade experience and out-of-state licensing pathways, subject to the documentation requirements that apply to the applicant.
Those requirements may involve proof of four years of plumbing work experience, employer affidavits, and license verification.
The correct pathway depends on the applicant's circumstances.
Most importantly, applicants must first submit their licensing application to the Indiana Plumbing Commission.
They cannot simply schedule the examination without the state's approval.
Once the Commission approves eligibility, the candidate may register and schedule the test with PROV.
That sequence should be built into the candidate's preparation plan.
Studying is important, but missing an application document can delay the entire licensing process.
The official PROV Journeyman Plumber blueprint contains nine examination categories.
Vents is the largest category, with 17 questions.
Sanitary Drainage follows with 15 questions.
Water Supply and Distribution contains 14 questions.
Those three categories account for 46 of the 90 examination questions.
They should receive significant attention during study.
However, plumbing fixtures, water heaters, general requirements, Indiana business, storm water systems, and developed-length calculations also appear on the test.
The candidate cannot ignore those areas simply because they contain fewer questions.
Venting is one of the most important plumbing topics.
Vents help a drainage system operate properly by allowing air movement and supporting trap-seal protection.
Incorrect vent arrangements can create problems with pressure changes and fixture drainage.
Venting questions may ask candidates to identify proper installation methods, pipe sizes, developed lengths, and applicable exceptions.
Sanitary drainage is another major category.
Students should review drainage piping, fixture-unit calculations, fittings, cleanouts, changes in direction, drainage slopes, and installation requirements.
Water supply and distribution questions may involve potable water, water service, distribution piping, fixture demand, backflow prevention, valves, and system sizing.
These subjects are closely connected to everyday plumbing work.
Still, answering a licensing question is different from completing a familiar job.
On a jobsite, a plumber can inspect the installation and ask questions.
In the examination room, the candidate must read a short problem, identify the relevant code rule, and choose the best answer.
The clock does not provide a coffee break every time a sizing table looks confusing.
That is where repeated practice becomes valuable.
Indiana also tests Developed Length and Isometric Analysis.
These questions involve understanding piping diagrams, calculating developed pipe lengths, and interpreting system layouts.
Students should learn to trace each pipe segment and follow changes in direction.
They should also recognize the difference between a straight-line distance and the developed length of piping.
Developed length follows the actual piping path.
If a pipe travels horizontally, rises vertically, and then turns again, those segments must be considered.
Isometric diagrams help show this arrangement in three dimensions.
The examination contains eight questions in that category.
Students should practice reading diagrams before test day.
The published examination also includes six Indiana Business questions.
Journeyman candidates should study Indiana plumbing licensing terminology, responsibilities, and applicable administrative requirements.
Do not confuse those six questions with the separate Plumbing Contractor examination's business category, which has a different question count.
The PROV bulletin lists 90 questions for each examination, but the subject distribution differs.
This guide follows the Journeyman Plumber examination outline, not the contractor exam outline.
Another helpful point is the test format.
PROV allows candidates to use approved reference books.
Permanent tabs and pre-exam highlighting are generally permitted within the published rules.
Moveable tabs, Post-it notes, extra inserted papers, photocopied reference books, and study guides are not allowed inside the testing room.
Only a simple four-function calculator is permitted.
Preparing reference books correctly before the exam can save time.
Learn the code chapters, index, definitions, sizing tables, and Indiana amendments.
Then practice finding the appropriate rule quickly.
With 90 questions in 180 minutes, candidates have an average of two minutes per question.
Some questions may be answered quickly.
Others require careful code lookup or piping calculations.
A focused six-week study plan can help candidates balance the different subjects.
Begin with plumbing code organization and general requirements.
Spend additional time on venting, sanitary drainage, and water supply.
Review fixtures, water heaters, storm drainage, and Indiana business requirements.
Then practice developed-length and isometric calculations.
Complete timed 90-question practice examinations during the final week.
After passing, candidates must finish any remaining Indiana Professional Licensing Agency requirements before receiving their license.
The Journeyman Plumber license remains separate from Plumbing Contractor licensing.
Individuals who want to operate an independent plumbing contracting business should review the separate Plumbing Contractor application and examination requirements.
This guide includes the current PROV examination details, official question breakdown, Indiana licensing pathways, reference-book information, plumbing-system diagrams, six-week study plan, Contractor Exam Preps product recommendations, an Indiana-themed credential illustration, clickable FAQs, and a related 1ExamPrep YouTube video.
Important Indiana Journeyman Plumber 2026 Update: The official PROV Candidate Information Bulletin dated June 24, 2026, lists a 90-question, three-hour, open-book Journeyman Plumber examination. The approved reference list centers on the 2006 IPC Indiana Edition, the 2012 Indiana Amendments, and Indiana plumbing laws or the accepted Indiana Plumbing Supplement. The bulletin does not publish a numeric Journeyman passing percentage, so verify that requirement with the Indiana Plumbing Commission or PROV rather than relying on older prep websites. Contractor Exam Preps also sells 2021 and 2024 IPC-based study materials, but newer educational editions are not automatically approved examination references. Candidates need Indiana Plumbing Commission eligibility approval before registering through PROV.
An Indiana Journeyman Plumber is a licensed plumbing tradesperson who has met the applicable state training, experience, and examination requirements.
Journeyman plumbers install, maintain, alter, and repair plumbing systems within the authority granted by Indiana law.
Plumbing systems provide potable water and safely remove wastewater.
They also include vents, traps, fixtures, valves, water heaters, and other connected equipment.
Every part must be installed according to applicable requirements.
A water distribution system must provide water to fixtures while maintaining proper protection against contamination.
Drainage piping must carry wastewater away from fixtures.
Venting helps drainage systems operate properly and protects trap seals.
Traps help prevent sewer gases from entering occupied spaces.
Backflow prevention helps protect the potable water supply from unwanted contamination.
Water heaters require attention to temperature, pressure, piping, and safety devices.
These systems must work together.
A plumber may install each pipe correctly but still create a problem if the overall piping arrangement violates a venting or drainage requirement.
That is why journeyman-level knowledge includes both practical installation skills and code interpretation.
Indiana regulates the profession through the Indiana Plumbing Commission.
The Professional Licensing Agency manages applications and licensing information.
PROV administers the required examination after the Commission approves the candidate's eligibility.
Applicants must be at least 18 years old.
Indiana's approved apprenticeship pathway involves four years of training and the required completion certification.
Other qualification routes may apply to experienced plumbers and applicants licensed in another state.
Those applicants must provide the appropriate records and affidavits.
The precise documentation depends on the licensing pathway.
Journeyman licensing is not the same as independent plumbing contractor licensing.
Indiana offers a separate Plumbing Contractor credential for individuals who qualify to undertake plumbing contracting responsibilities.
Contractor applicants have different administrative requirements and a separate PROV examination outline.
License: Indiana Journeyman Plumber.

PROV bulletin: June 24, 2026.
Journeyman exam: 90 questions in three hours.
Largest subject: Vents, 17 questions.
Exam books: 2006 IPC Indiana references and state amendments.
Passing score: Verify with PROV or the Commission because the current public bulletin does not give a numeric standard.
This is the largest category on the Indiana Journeyman Plumber examination. Study vent-system purpose, trap-seal protection, vent connections, vent sizing, developed lengths, and common vent configurations. Learn how to locate permitted vent arrangements and exceptions in the approved plumbing code.
Study building drains, building sewers, drainage piping, fittings, traps, cleanouts, fixture-unit values, slopes, drainage sizing, and testing. Practice choosing the correct drainage requirement from the facts provided in a question.
Review potable-water supplies, pipe materials, valves, water distribution, water service, fixture demand, sizing tables, pressure, and backflow prevention. Study connections and methods used to protect drinking water against contamination.
Study plumbing fixtures, fixture fittings, installation requirements, clearances, traps, faucets, water closets, lavatories, sinks, showers, and related equipment. Review fixture counts and access requirements where applicable.
Practice reading piping diagrams and adding pipe segments along the actual piping path. Learn to recognize horizontal, vertical, and offset piping. Review isometric views, fixture connections, pipe lengths, and sizing problems.
Study code administration, materials, joining methods, supports, protection of piping, testing, installation requirements, definitions, and commonly applicable plumbing rules.
Review water-heater installations, valves, temperature and pressure protection, discharge piping, water connections, and related safety requirements. Learn the difference between a general installation practice and a specific code requirement.
Study Indiana plumbing licensing laws, trade responsibilities, administrative requirements, and relevant licensing terminology. Use the permitted Indiana law reference or Plumbing Supplement to prepare.
Review roof drains, leaders, conductors, storm drainage piping, sizing concepts, and system connections. Study storm-water arrangements separately from sanitary drainage requirements.
Total: 90 questions.
Top three: Vents, Sanitary Drainage, and Water Supply, 46 questions combined.
Exam time: 180 minutes.
Important: This is the Journeyman blueprint. The separate Plumbing Contractor exam uses different subject counts.
Begin with the correct license and examination.
Indiana Journeyman Plumber and Plumbing Contractor are separate classifications.
The Journeyman exam includes 90 questions and allows three hours.
Its largest subjects are venting, sanitary drainage, and water supply.
Study those first, but remember that every published category contributes to the total.
Next, become familiar with the approved reference materials.
Learn how the 2006 IPC Indiana reference is organized.
Review the definitions, chapter titles, tables, and index.
Keep the Indiana amendments close to your main study reference.
A rule in the base IPC may be affected by a state amendment.
Practice checking both when a question involves an Indiana-specific requirement.
Venting: Trap protection, vent connections, lengths, and sizing.
Drainage: Pipe sizing, fixture units, cleanouts, slopes, and fittings.
Water Supply: Potable water, pressure, distribution, and backflow protection.
Fixtures: Fixture types, fittings, installation, and clearances.
Water Heaters: Protection devices, installation, valves, and discharge piping.
Storm Water: Roof drains, leaders, and storm piping.
Isometrics: Drawings, developed lengths, pipe routing, and calculations.
Indiana Business: Licensing laws and administrative requirements.
Spend time practicing isometric drawings.
Begin with simple piping arrangements.
Identify each vertical, horizontal, and offset section.
Trace the actual piping route and calculate developed lengths.
Then practice diagrams with multiple fixtures and branches.
For code questions, locate the relevant chapter before searching for a specific section.
Use permanent tabs that comply with PROV rules.
Highlight important provisions before test day.
Do not add temporary notes or extra photocopied pages to examination references.
The Indiana Journeyman Plumber Exam Book Package supports preparation with the specific Indiana code and law references.
The 2026 Indiana Study Guide and Online Course provides additional practice questions, explanations, and plumbing videos.
Because that course uses the newer 2024 IPC, compare examination-specific answers against the authorized 2006 IPC Indiana references.
Finish each week with a timed practice session.
Record the questions you missed and review the relevant rule.
This method builds trade knowledge and faster reference navigation.
This simplified illustration shows how plumbing supply, drainage, and venting systems serve common fixtures.
Simplified educational diagram, not a compliant piping layout or installation drawing.
Choose the Indiana Journeyman Plumber credential rather than the separate Plumbing Contractor classification.
Review the approved apprenticeship pathway or the plumbing trade experience and out-of-state license requirements.
Collect apprenticeship completion certification, employer affidavits, and license verification as required.
Pay the current application fee and wait for Indiana Plumbing Commission eligibility approval.
Study the 2006 IPC Indiana reference, 2012 amendments, and approved Indiana legal material.
Focus on venting, sanitary drainage, water supply, fixtures, isometrics, water heaters, storm water, general requirements, and Indiana business.
Take the 90-question examination in three hours using only authorized materials.
Follow the Commission's post-examination instructions and renew by your assigned odd-year deadline.
These percentages are calculated from the official 90-question PROV examination blueprint.
Official total: 90 questions.
Largest category: Vents, 17 questions.
Top three categories: 46 questions combined.
Time: 180 minutes.
Study recommendation: Give the largest subjects extra time without neglecting the remaining six categories.

The Indiana Journeyman Plumber examination allows authorized reference books.
That does not remove the need to study.
With 90 questions and a three-hour limit, candidates need to find answers efficiently.
Current PROV rules: Authorized references, permanent tabs, and pre-exam highlighting may be used as permitted.
Not allowed: Temporary tabs, added loose documents, exam-prep study guides, and marking books during testing.
Calculator: Simple four-function model only.
An Indiana Journeyman Plumber is an individual tradesperson licensed to perform plumbing work under the applicable state rules.
Journeyman plumbers work with potable water systems, fixtures, drains, waste piping, vents, water heaters, valves, and related equipment.
The work may involve residential, commercial, or other plumbing installations.
Plumbing installation involves much more than joining pipes.
A plumber must understand how fixture loads affect piping requirements.
Drainage systems need the correct slope, fittings, and sizing.
Venting arrangements need to support the function of the drainage system.
Water supplies require protection against contamination.
Water heaters require proper safety devices and associated piping.
Materials must be used in suitable locations and joined correctly.
Inspection and testing help confirm that installations meet applicable requirements.
A journeyman's practical work should reflect these technical standards.
The Indiana Journeyman Plumber license does not automatically authorize an independent plumbing contracting business.
Indiana regulates Plumbing Contractors separately.
Contractor licensing may involve additional responsibilities relating to business operation, supervision, and plumbing work performed under the contractor's authority.
Individuals planning to start a plumbing company should review the separate Plumbing Contractor requirements before bidding or performing regulated work independently.
Journeyman Plumber: Individual plumbing trade license.
Plumbing Contractor: Separate Indiana licensing classification.
Journeyman exam: 90 questions, three hours, nine subjects.
Contractor exam: Separate 90-question examination with different question weights.
| Classification | Credential | Main Difference |
|---|---|---|
| Plumbing Apprentice | Apprentice Registration | Participates in approved plumbing training. |
| Journeyman Plumber | Individual Trade License | Performs qualifying plumbing work under state licensing rules. |
| Plumbing Contractor | Contractor License | Separate authority for regulated plumbing contracting work. |
| Plumbing Corporation | Business Registration | Additional corporate plumbing licensing responsibilities. |
| Apprentice Minimum Age | 17 | Applicable apprentice registration requirement. |
| Journeyman Minimum Age | 18 | Required for Journeyman application. |
| Journeyman Apprenticeship | Four Years | Approved program and completion certification. |
| Journeyman Examination | PROV | 90 questions, three hours. |

Indiana Commission-Approved Program
Experience and License Verification
PROV Journeyman Plumber
Important: Applicant documentation varies by licensing route. Follow the current Indiana Plumbing Commission instructions for your circumstances.
The Indiana Journeyman Plumber exam can be challenging because it tests several plumbing subjects in a short amount of time.
It has 90 questions and a three-hour time limit.
That provides an average of two minutes per question.
Some questions require general trade knowledge.
Others require finding an exact code provision or using a sizing table.
Developed-length and isometric questions may involve multiple steps.
Venting is the most heavily tested category.
It contains 17 questions.
Venting rules can be difficult because similar piping arrangements may be controlled by different requirements.
A question may turn on a vent connection, pipe size, developed length, or exception.
Sanitary drainage is another large category, with 15 questions.
Students need to understand drainage materials, fixture units, fittings, cleanouts, slopes, and sizing.
Water supply and distribution includes 14 questions.
That category may involve pipe sizes, fixtures, valves, pressure, cross-connections, and backflow prevention.
These three categories account for more than half of the examination.
They should receive regular practice.
However, the remaining categories still matter.
Fixtures, water heaters, storm drainage, general requirements, Indiana business, and isometric analysis all contribute questions.
One common difficulty is using the right code edition.
The official PROV bulletin lists the 2006 IPC Indiana Edition, 2012 Indiana amendments, and approved state legal references.
Many newer exam-prep products now use the 2021 or 2024 IPC.
Those newer materials can teach useful plumbing concepts, but the exact examination references may differ.
Students should practice with the approved Indiana books to become familiar with the rules and organization relevant to PROV testing.
The Indiana Journeyman Plumber Exam Book Package helps candidates gather the Indiana-specific references.
The 2026 Indiana Journeyman Plumber Study Guide and Online Course provides additional plumbing instruction and practice exercises.
Use both kinds of preparation carefully.
Study with the official references for exam-specific requirements and use newer educational materials to strengthen general plumbing understanding.
Another common difficulty is test-day timing.
An open-book examination can create the temptation to look up every answer.
That strategy is not always efficient.
Candidates should answer familiar questions promptly and use code lookup for questions that require confirmation.
Practice helps develop that balance.
PROV exam: 90 questions and three hours.
Allowed: Authorized references, pencil, and simple four-function calculator.
Not allowed: Study guides, temporary tabs, loose photocopies, and unauthorized electronics.
Contractor Exam Preps offers both Indiana examination reference books and supplemental study courses.
Choose the product that matches your preparation goal and verify the allowed code edition before taking books to the PROV testing center.

Best exam-reference choice: Indiana Journeyman Plumber Exam Book Package.
Additional learning: 2024 IPC and 2021 IPC study packages.

Preparing for the Indiana Journeyman Plumber examination is an important step toward earning a professional plumbing trade license.
Indiana licenses journeyman plumbers through the Indiana Plumbing Commission and the Professional Licensing Agency.
This license recognizes individuals who have met the appropriate training, experience, and examination requirements.
Applicants must be at least 18 years old.
One qualification pathway involves completing an approved four-year plumbing apprenticeship program.
Other eligible candidates may qualify through documented plumbing experience and applicable out-of-state licensing provisions.
Each pathway has specific documentation requirements.
Applicants should carefully review the current Indiana Professional Licensing Agency instructions before submitting their paperwork.
An important part of the process is obtaining approval before testing.
Indiana requires candidates to have their examination eligibility reviewed and approved by the Plumbing Commission.
After approval, they may register and schedule the examination through PROV.
The current official PROV Candidate Information Bulletin is dated June 24, 2026.
It lists a 90-question Journeyman Plumber examination with a three-hour time limit.
That gives candidates an average of two minutes per question.
The examination is computer based and uses multiple-choice questions.
Authorized reference books are permitted.
The public bulletin does not identify a specific numeric Journeyman passing score, so candidates should verify that requirement directly with PROV or the Commission.
Indiana's examination reference list is especially important.
The primary code reference is the 2006 International Plumbing Code, second printing, Indiana Edition, 2012.
The bulletin also permits specified 2006 IPC substitutes.
Students must also review the 2012 Indiana Amendments, 675 IAC 16-1.4.
Another listed reference is the 2014 compilation of Indiana Code and Administrative Code.
The Indiana Plumbing Supplement may be used as an approved substitute for that compilation.
These publications help candidates study and apply Indiana-specific requirements.
They also provide the foundation for examination reference navigation.
Contractor Exam Preps offers the Indiana Journeyman Plumber Exam Book Package.
This package is designed around the code and state references listed for the Indiana Journeyman examination.
It is a practical choice for candidates who need to organize the correct exam books.
The store also offers the 2026 Indiana Journeyman Plumber Study Guide and Online Course.
That product includes general plumbing review, instructional videos, practice questions, and isometric exercises.
However, it is based on the newer 2024 IPC.
The Indiana Journeyman Plumber Exam Prep Package Based on the 2021 IPC is another supplemental option.
These newer study editions can help build plumbing knowledge, but students should verify exam-specific rules using the references approved by PROV.
The official Indiana Journeyman examination covers nine subject areas.
Vents is the largest category, with 17 questions.
Sanitary Drainage includes 15 questions.
Water Supply and Distribution contains 14 questions.
Those three subjects account for 46 of the 90 questions.
That makes them important study priorities.
The remaining examination topics include fixtures, general requirements, water heaters, Indiana business, storm water systems, and developed-length and isometric analysis.
Every category deserves attention.
Students should practice using plumbing diagrams, code tables, measurements, and pipe-sizing methods.
Developed-length calculations deserve regular review because they require careful tracing of the actual piping route.
Venting questions may involve trap protection, sizing, connections, and installation requirements.
Drainage questions may involve fixture units, fittings, cleanouts, and slopes.
Water supply questions may cover pipe sizing, pressure, valves, distribution, and backflow prevention.
Strong preparation combines technical understanding with effective reference navigation.
The exam is open book, but candidates cannot bring unauthorized study guides or loose notes.
Permanent tabs and highlighting are permitted within PROV's published requirements.
Moveable tabs, Post-it notes, and inserted photocopied materials are prohibited.
Students should prepare compliant books before test day.
A six-week study plan can help organize preparation.
Begin with general plumbing code requirements and Indiana amendments.
Continue with venting, sanitary drainage, and water distribution.
Review fixtures, water heaters, storm water, and Indiana business requirements.
Practice plumbing mathematics and isometric analysis regularly.
During the final week, complete timed 90-question examinations using approved references.
Review incorrect answers carefully rather than simply memorizing a correct option.
After passing, candidates must complete any remaining state licensing requirements.
Passing the examination does not automatically issue a license.
Indiana Journeyman Plumber licenses also differ from Plumbing Contractor licenses.
The journeyman credential is an individual trade license.
Independent plumbing contracting requires meeting the separate contractor licensing requirements.
Current Indiana Journeyman Plumber licenses expire on December 31 of odd-numbered years, and the state lists a $30 renewal fee.
Applicants and license holders should verify the latest renewal and fee information directly with IPLA.
With qualifying training, accurate application records, the correct Indiana plumbing references, consistent study, and realistic timed practice, candidates can approach the Indiana Journeyman Plumber examination with a better plan.
The goal is not simply to answer questions quickly.
It is to understand how plumbing systems work, how their parts interact, and how to apply the requirements that protect buildings and the people who use them.
