Ready to become a licensed New Hampshire Journeyman Plumber? This complete exam preparation guide explains the state's plumbing licensing requirements, the Prov examination, official subject categories, apprenticeship hours, plumbing codes, approved reference books, fees, renewals, and related preparation materials from Contractor Exam Preps.
Plumbers do much more than fix leaky faucets.
They help deliver safe drinking water, remove wastewater, protect buildings from water damage, maintain sanitary systems, and keep essential fixtures working.
Think about the plumbing inside a large school, restaurant, apartment building, or hospital.
There may be hundreds of pipes, fixtures, valves, drains, vents, and connections.
Each component must be installed with the proper materials and code requirements.
After all, discovering that a drain slopes the wrong direction is not a problem anyone wants to celebrate!
New Hampshire Journeyman Plumber licensing provides a recognized path for skilled workers who have completed substantial plumbing education and practical training.
Exam preparation helps candidates bring those skills together.
Journeyman plumbers are licensed through the New Hampshire Mechanical Licensing Board within the Office of Professional Licensure and Certification, commonly called OPLC.
The Board establishes qualifications for individual plumbers and regulates the applicable licensing requirements.
The licensing system includes plumbing apprentices, journeyman plumbers, master plumbers, and mechanical business entities.
These categories have different responsibilities and application requirements.
The Journeyman Plumber license is an individual professional credential.
It is not automatically a license to operate an independent plumbing contracting business.
Under New Hampshire law, a journeyman plumber generally installs, maintains, and repairs plumbing under the direction of a master plumber.
Business entities performing plumbing may also require separate mechanical business licensing.
The current published plumbing examination bulletin identifies Prov, Inc. as the testing provider for the New Hampshire Mechanical Board.
Prov administers the journeyman plumber examination through its testing program.
Eligible candidates may schedule at a participating testing center or use the remote testing option described in the current bulletin.
Remote candidates must have suitable equipment, an approved room, a working camera, a microphone, and a reliable internet connection.
All testing candidates must follow the applicable identification, examination security, and reference-book rules.
The published November 15, 2025 Prov Candidate Information Bulletin lists 85 multiple-choice questions for the New Hampshire Journeyman Plumber examination.
Candidates have three hours, or 180 minutes.
The passing standard is 70%.
For 85 equally scored questions, this means reaching at least 60 correct answers.
The average time available is approximately two minutes and seven seconds per question.
This is enough time for careful work, but not enough to search blindly through a codebook on every question.
Students should practice both trade knowledge and efficient code navigation.
New Hampshire changed its adopted state building codes on July 1, 2026.
The state building code now incorporates the 2024 International Plumbing Code, subject to New Hampshire amendments and applicable local requirements.
However, the most recent publicly located Prov Journeyman Plumber bulletin still lists the 2018 International Plumbing Code as an examination reference.
These are different documents serving different purposes.
The adopted 2024 IPC governs current installations under the applicable state and local rules.
The Prov bulletin governs the listed materials for the licensing examination.
Candidates should check for a newer bulletin or obtain confirmation from Prov before bringing a newer IPC edition to their test.
The fact that a codebook is currently adopted does not automatically mean it appears on the exam-room reference list.
The November 2025 Prov bulletin lists two resources for the Journeyman Plumber examination:
The exam is open book, but only authorized references may be used.
Prov permits qualifying highlighting, underlining, and permanent tabs.
Handwritten notes, movable tabs, Post-it notes, inserted photocopies, and practice-exam study guides are not allowed in the testing room.
These restrictions apply whether a book is purchased separately or comes inside a larger exam preparation package.
The published Prov examination blueprint contains seven major subject areas.
These categories total 85 questions.
Venting Regulations is the largest section at 20 questions.
Drainage Requirements is the next largest with 15 questions.
Together, venting and drainage account for 35 questions, or approximately 41% of the examination.
That gives candidates a useful starting point for organizing study time.
Plumbing calculations account for 10 official examination questions.
Students should review basic measurements, conversions, slopes, pipe sizing, developed lengths, plumbing fixture units, and system demand.
Mathematics is essential because plumbing systems depend on correct dimensions and properly selected pipe sizes.
Drainage slope calculations are a common study concern.
Water supply sizing and fixture demand also require understanding tables and code procedures.
Practice solving problems step by step rather than memorizing isolated answers.
Drainage Requirements accounts for 15 examination questions.
Study building drains, building sewers, horizontal branches, vertical stacks, drainage fittings, cleanouts, drainage slope, and pipe sizing.
Understand how gravity drainage systems remove wastewater from plumbing fixtures.
Review the role of approved drainage materials and fittings.
Learn when cleanouts are needed and why proper access matters.
Practice drainage fixture unit calculations and identifying the correct pipe-sizing tables.
Venting is the largest examination category with 20 questions.
The vent system helps protect trap seals and maintain suitable pressure conditions within drainage piping.
Students should understand individual vents, common vents, wet venting, circuit venting, vent stacks, stack vents, and permitted arrangements under the applicable plumbing code.
Practice locating vent sizing tables.
Study minimum sizes, connection requirements, vent termination, distances, and exceptions.
Venting questions may require reading diagrams and identifying how pipes connect.
This is an important reason to practice isometric plumbing drawings.
Fixtures and Faucets accounts for 10 questions.
Study sinks, lavatories, toilets, showers, bathtubs, faucets, urinals, and related fixture fittings.
Understand fixture installation, clearance, water connections, drainage connections, and accessibility principles.
Review where fixtures are required and how plumbing fixtures interact with water supply and drainage systems.
Study code definitions carefully.
Traps and Interceptors contributes 10 examination questions.
Traps help prevent sewer gases from entering occupied buildings.
Study trap seals, trap arms, approved trap materials, prohibited arrangements, and protection of trap seals.
Review grease interceptors and other interceptor systems used where specific waste must be separated before entering drainage piping.
Understand why the correct installation matters.
A trap that cannot maintain its seal is a plumbing problem waiting to introduce itself to everyone in the room.
Water Distribution accounts for 10 questions.
Study potable water service, distribution piping, valves, water pressure, pipe sizing, fixture demand, and acceptable piping materials.
Review cross-connection protection and backflow prevention.
Understand the purpose of pressure-regulating devices and water supply protection.
Study hot and cold water distribution and the connections serving fixtures and water heaters.
Practice water supply fixture unit calculations and table navigation.
Plumbing and Fundamentals accounts for 10 questions.
This category involves plumbing terminology, materials, fittings, basic installation requirements, system principles, and general trade practices.
Students should understand joining methods, supports, pipe protection, approved materials, and basic plumbing tools.
Review installation requirements for different locations and system conditions.
Know when particular piping materials are suitable.
Learn the importance of following manufacturer instructions and adopted building standards.
Protecting potable water is one of the most important plumbing responsibilities.
Backflow can allow contaminated water to enter a clean water supply when pressure conditions change.
Study approved backflow protection methods, air gaps, and cross-connection concerns.
Review which methods apply to different plumbing conditions.
These subjects connect strongly to the Water Distribution and Plumbing Fundamentals categories.
Isometric drawings represent plumbing systems in a way that helps show vertical and horizontal piping relationships.
They are valuable for studying drainage, waste, vents, fixture branches, and pipe connections.
Practice identifying fixture connections, drainage stacks, vent arrangements, pipe direction, and system layout.
A clear isometric drawing can make complicated systems easier to understand.
Contractor Exam Preps offers New Hampshire products with isometric drawing walkthroughs and plumbing mathematics lessons.
The New Hampshire journeyman path generally includes 8,000 hours of plumbing work experience and at least 600 hours of related education.
Applicants must meet the current Mechanical Licensing Board apprenticeship and documentation requirements.
The application process may involve an apprenticeship completion certificate, evidence of supervised experience, and a signed letter from the licensed supervising plumber.
Special pathways may exist for individuals who already hold plumbing licenses in other jurisdictions.
Applicants should use the current Mechanical Licensing Board rules instead of assuming all out-of-state credentials transfer automatically.
The current published New Hampshire licensing fee schedule lists $190 for initial or reinstated journeyman plumber licensure.
The biennial renewal fee is $180.
The November 2025 Prov bulletin lists a $90 examination fee per attempt.
Testing and licensing fees are separate payments.
These amounts may change, so applicants should review the current OPLC and Prov schedules before submitting payments.
New Hampshire journeyman plumbing licenses are generally renewed every two years.
Under Mec 404.01, licensees must complete at least six hours of approved continuing education for each applicable plumbing endorsement during the two-year cycle.
Approved classes focus on adopted codes, laws, standards, and licensing rules.
The education is usually completed through separate approved three-hour training sessions.
Licensees should keep course documentation and renew through the OPLC process.
A journeyman plumber generally works under the direction of a master plumber.
A master plumber has a higher level of licensing responsibility.
Under the current rules, master plumber applicants generally must have held a New Hampshire journeyman license for at least six months and must meet additional examination and application requirements.
The Prov Master Plumber exam is separate from the Journeyman Plumber exam.
Students should not confuse the 85-question journeyman blueprint with the 100-question master blueprint.
Holding an individual Journeyman Plumber license does not automatically authorize operation of an independent plumbing contracting business.
New Hampshire has separate rules for mechanical business entities.
Businesses performing regulated plumbing must review mechanical business entity licensing and applicable master plumber responsibilities.
This distinction is especially important for people searching for "Journeyman Plumber Contractor Exam Prep."
The journeyman examination prepares an individual for professional licensing, while business licensing is a separate regulatory matter.
Contractor Exam Preps offers several New Hampshire-specific products based on the 2024 International Plumbing Code.
The 2026 New Hampshire Journeyman Plumber Complete Books, Tabs and Course Package includes the 2024 IPC, quick-reference tabs, a journeyman study guide, online course access, and flash cards.
The 2026 New Hampshire Journeyman Plumber Study Guide and Online Course combines structured study material with guided training.
The 2026 New Hampshire Journeyman Plumber Study Guide offers a focused book option with more than 700 practice questions and answer keys.
The 2024 IPC products are especially useful for current plumbing-code education.
However, the publicly located Prov examination bulletin still specifies the 2018 IPC.
Confirm the latest authorized test references before assuming a newer codebook is permitted in the examination room.
Begin by reviewing the current OPLC journeyman licensing checklist.
Confirm your apprenticeship, education, and work experience records.
Read the current Prov Candidate Information Bulletin.
Study all seven official examination categories.
Spend extra time on venting and drainage.

Preparing for a New Hampshire Journeyman Plumber license is an important step for people building a professional plumbing career.
Plumbers help protect public health and maintain the essential systems that buildings depend on every day.
Water supply, drainage, vents, traps, fixtures, and fittings all need to work together.
When these systems are designed and installed correctly, they provide reliable plumbing services for residential and commercial buildings.
When installation requirements are ignored, the result can involve leaks, drainage problems, water damage, or unsafe water conditions.
That is why skilled plumbing work requires both hands-on training and sound knowledge of plumbing codes.
New Hampshire licenses individual plumbers through the Mechanical Licensing Board within the Office of Professional Licensure and Certification.
The state recognizes several plumbing credential levels, including apprentice, journeyman, and master plumber.
The Journeyman Plumber license is an important qualification for individuals performing plumbing work under the direction of a master plumber.
It is separate from master plumber licensing and separate mechanical business entity requirements.
The standard New Hampshire journeyman pathway generally requires 8,000 hours of practical plumbing experience and 600 hours of qualifying education.
Candidates must also meet applicable apprenticeship completion, supervision, examination, and application requirements.
The licensed plumber supervising the applicant's work may need to provide a signed letter confirming the qualifying experience and competence.
The state also has provisions for applicants with previous out-of-state plumbing licenses.
Those applicants should review the current licensing rules rather than assume that every license automatically transfers.
The plumbing examination provider identified in the current publicly located bulletin is Prov.
Its November 15, 2025 Candidate Information Bulletin lists 85 questions for the New Hampshire Journeyman Plumber exam.
Candidates have three hours to finish the examination.
The published passing score is 70%.
The examination is open book, but only authorized references may be used.
The currently located bulletin lists the 2018 International Plumbing Code and the Purpose and Scope of Administrative Rules of the Board.
A major 2026 change makes code editions particularly important.
New Hampshire adopted the 2024 International Plumbing Code effective July 1, 2026.
That means plumbing installations should follow the currently adopted code and applicable amendments.
However, the located Prov examination bulletin still identifies the 2018 IPC for examination preparation.
Candidates should confirm whether a newer bulletin has updated the exam-room reference edition.
Using the wrong book edition during an open-book examination could cause unnecessary difficulty.
The Journeyman Plumber examination contains seven official content categories.
Calculations accounts for 10 questions.
Drainage Requirements accounts for 15.
Fixtures and Faucets accounts for 10.
Plumbing and Fundamentals accounts for 10.
Traps and Interceptors accounts for 10.
Venting Regulations accounts for 20.
Water Distribution accounts for 10.
Venting is the largest subject on the test.
Drainage is the second largest.
Together, these two categories represent 35 of the 85 questions.
That is an important signal for study planning.
Students should spend significant time understanding vent systems, drainage piping, traps, and fixture connections.
However, every examination category deserves preparation.
Plumbing calculations may involve measurements, slopes, fixture units, pipe sizes, and system demand.
Venting requires knowledge of different vent arrangements and their limitations.
Drainage questions may involve pipes, fittings, cleanouts, slopes, and sizing tables.
Fixtures and Faucets covers common plumbing fixtures and their installation requirements.
Traps and Interceptors includes trap seals, trap arms, and systems designed to separate specific waste materials.
Water Distribution includes potable supply, backflow prevention, pressure, valves, and sizing.
Plumbing and Fundamentals involves materials, tools, approved installation methods, and basic plumbing principles.
Practice questions can help students identify difficult subjects before examination day.
Isometric drawings are also useful because they show how drainage and vent systems connect.
Contractor Exam Preps offers several products specifically developed for New Hampshire Journeyman Plumber exam preparation.
The 2026 Complete Books, Tabs and Course Package includes the 2024 IPC, reference tabs, study guide, online course, and flash cards.
The New Hampshire Study Guide and Online Course offers a more focused combination of printed and online materials.
The New Hampshire Journeyman Plumber Study Guide includes more than 700 practice questions and answer keys.
These products support newer-code study and preparation across common plumbing topics.
Students should remember that a retail study package does not change the official exam-room reference rules.
The 2024 IPC products are appropriate for learning current adopted plumbing standards, while the authorized exam edition must be confirmed with Prov.
The official Prov bulletin also explains exam security rules.
Permitted highlighting, underlining, and permanent tabs may be used in approved books.
Handwritten notes, loose papers, movable tabs, and practice guides are not permitted in the exam room.
Understanding these rules before the test can help prevent problems during check-in.
New Hampshire licensing has separate costs.
The published Prov examination fee is $90 per attempt.
The initial Journeyman Plumber license fee is $190.
The biennial renewal fee is $180.
Licensed journeymen must complete at least six hours of approved continuing education during each two-year renewal cycle.
Additional licensing requirements may apply to plumbers who want to advance to the master level or operate a plumbing business.
A consistent six-week study plan can improve preparation.
Start with licensing rules, reference navigation, and plumbing fundamentals.
Then study drainage and venting.
Continue with fixtures, traps, interceptors, water distribution, and calculations.
Finish with repeated 85-question practice tests using a three-hour timer.
Review every incorrect answer and revisit weak subjects.
Preparation is not about memorizing a thousand disconnected facts.
It is about understanding the plumbing system, locating accurate code information, and making the right decision under time pressure.
With organized study, practical experience, and accurate licensing information, candidates can approach the New Hampshire Journeyman Plumber exam with greater confidence.
New Hampshire Journeyman Plumber Contractor Exam Prep helps plumbing apprentices and experienced workers understand how to prepare for the journeyman licensing examination.
New Hampshire licenses plumbers through the Mechanical Licensing Board within the Office of Professional Licensure and Certification. The Board regulates individual plumbing qualifications and related licensing requirements.
A Journeyman Plumber is an individual who generally installs, maintains, and repairs plumbing under the direction of a master plumber. The license demonstrates that the individual has met the applicable state requirements for professional plumbing work.
The standard licensing path includes a qualifying apprenticeship, 8,000 hours of relevant plumbing experience, and 600 hours of related education. Applicants must provide required supporting documentation, which may include an apprenticeship completion record and a signed letter from the supervising licensed plumber.
The licensing process also requires an accepted examination result, a complete application, identification, and the appropriate licensing fee. Applicants with previous plumbing licenses from other jurisdictions may qualify under additional Board provisions.
Prov, Inc. administers New Hampshire plumbing examinations under the current publicly located Candidate Information Bulletin. The November 15, 2025 bulletin lists 85 questions for the Journeyman Plumber examination.
Candidates have three hours to complete the examination. The published passing score is 70%, meaning at least 60 correct answers if all 85 questions are scored equally.
The examination is open book. Candidates may use authorized reference books under Prov's restrictions.
The located bulletin lists the 2018 International Plumbing Code and the Board's Purpose and Scope of Administrative Rules as the journeyman reference materials.
New Hampshire's plumbing code changed on July 1, 2026, when the state adopted the 2024 International Plumbing Code. That edition now forms part of the adopted state building code, subject to applicable amendments and local requirements.
Because the examination bulletin still lists the 2018 IPC, candidates should not assume the 2024 IPC is automatically permitted in the testing room. Confirm the newest bulletin or ask Prov before scheduling.
The official journeyman examination outline contains seven categories totaling 85 questions. Calculations accounts for 10. Drainage Requirements has 15. Fixtures and Faucets has 10. Plumbing and Fundamentals has 10. Traps and Interceptors has 10. Venting Regulations has 20. Water Distribution has 10.
Venting is the largest category, followed by drainage. Together they represent more than 40% of the examination.
Students should devote significant attention to vent-system design, vent sizing, traps, drainage slopes, fixture units, and pipe sizing.
Drainage study includes building drains, building sewers, branch piping, fittings, cleanouts, and proper wastewater movement.
Venting study includes individual vents, common vents, wet venting, circuit vents, vent stacks, sizing, and termination requirements. Understanding isometric plumbing diagrams can help make these subjects easier.
Water Distribution study covers potable water supply, water service, pipe sizing, pressure, valves, backflow prevention, and hot and cold water connections.
Fixtures and Faucets involves common plumbing fixtures such as sinks, lavatories, water closets, showers, bathtubs, and related fittings. Students should understand installation principles, clearances, and connections.
Traps and Interceptors includes trap seals, trap arms, grease interceptors, and protection against sewer gases. Plumbing Fundamentals covers materials, fittings, supports, approved connections, and basic installation methods.
Plumbing mathematics is also important. Candidates should practice measurements, conversions, slopes, fixture unit calculations, developed lengths, and sizing tables.
Contractor Exam Preps offers New Hampshire-specific Journeyman Plumber products based on the 2024 IPC.
The Complete Books, Tabs and Course Package includes a 2024 IPC codebook, tabs, a study guide, online instruction, simulated examinations, and flash cards.
The New Hampshire Study Guide and Online Course offers another preparation option for students who want guided review. The standalone New Hampshire Journeyman Plumber Study Guide provides more than 700 practice questions and answer keys.
These products are helpful for current-code learning and organized preparation. However, retail materials do not determine which code edition Prov authorizes during the examination.
The Prov bulletin permits certain preparation methods for approved codebooks, including highlighting, underlining, and permanent tabs.
It does not permit handwritten notes, movable tabs, inserted photocopies, or practice-exam study guides in the examination room.
The published Prov examination fee is $90 per attempt. The New Hampshire journeyman license application and initial licensing fee is $190. The published two-year renewal fee is $180.
New Hampshire also requires approved continuing education. Journeyman Plumbers must complete at least six hours during each two-year licensing cycle for the applicable plumbing endorsement.
Licensed journeymen who wish to advance can review the separate Master Plumber requirements. Operating a plumbing business may involve additional mechanical business entity licensing.
A structured six-week study plan can begin with state licensing rules and plumbing fundamentals. The next weeks can focus on drainage, vents, fixtures, traps, interceptors, water distribution, and plumbing mathematics.
The final stage should involve repeated 85-question practice examinations with a three-hour time limit. Candidates should review missed answers and practice finding code provisions efficiently.
New Hampshire Journeyman Plumber candidates can improve preparation by understanding the official exam outline, confirming approved references, organizing their licensing documents, and practicing consistently.
