Exam Details

The ICC Master Plumber - G24-N exam is a trade qualification exam focused on master-level plumbing knowledge. It evaluates whether a candidate can understand, locate, and apply plumbing code provisions to practical trade scenarios involving installation, inspection, system layout, troubleshooting, service, and code compliance. The exam is multiple choice and is based on the approved reference for the selected exam cycle.

Candidates should prepare for a timed, reference-based exam that requires efficient use of the 2018 International Plumbing Code. The exam tests plumbing code knowledge, reference navigation, installation awareness, sizing concepts, system coordination, testing requirements, and the ability to apply code requirements to field conditions. Candidates should be ready to answer questions involving plumbing fixtures, fixture fittings, water supply, water distribution, sanitary drainage, vents, traps, cleanouts, interceptors, indirect waste, special waste, storm drainage, pipe materials, joints, connections, system testing, inspections, and safety-related plumbing provisions.

Major study areas may include administration, definitions, general plumbing regulations, fixtures, faucets, fixture fittings, water heaters, water supply and distribution, sanitary drainage, indirect and special waste, vents, traps, grease interceptors, oil separators, storm drainage, nonpotable water systems where applicable, piping materials, joints, connections, hanger and support requirements, testing, and code tables. Candidates should also understand how to use the index, definitions, footnotes, exceptions, and sizing tables efficiently.

Master plumber exam questions may describe an installed condition and ask which plumbing code requirement applies. A question may involve fixture spacing, fixture connections, trap requirements, vent sizing, drainage pipe slope, cleanout location, water pipe sizing, fixture unit values, pipe support, roof drainage, backflow prevention, indirect waste connections, interceptor requirements, or required testing. Some questions may require a table, definition, exception, or chapter-specific installation rule.

Because the exam is reference-based, candidates should study directly from the 2018 International Plumbing Code. Field experience can be valuable, but the correct exam answer is the one supported by the approved reference. Candidates should practice reading full code sections, checking related definitions, using tables accurately, reviewing notes and exceptions, and applying requirements exactly as written.

Open Book Test

The ICC Master Plumber - G24-N exam is an open book test. Candidates are expected to use approved references during the exam, but open book testing still requires serious preparation. The code book is valuable only when the candidate knows how to navigate it quickly and accurately.

Open book testing rewards organization, familiarity, and speed. Candidates should become comfortable using the table of contents, index, chapter structure, definitions, tables, figures, footnotes, exceptions, and cross-references in the 2018 International Plumbing Code. Highlighting and tabs can help organize important sections, but the tools work best when paired with repeated practice.

Candidates should practice locating provisions under timed conditions and using the book in the same way they plan to use it on exam day. A sanitary drainage question may require locating fixture units, pipe sizing, drainage slope, branch drain requirements, cleanout rules, or building drain provisions. A venting question may require checking vent sizing, vent connection requirements, wet vent provisions, circuit venting, stack vent rules, or distance limitations. A water distribution question may require reviewing sizing concepts, backflow protection, pressure requirements, pipe material rules, or hot water distribution provisions.

Candidates should follow current exam rules for approved references, tabs, highlighting, notes, loose papers, and materials allowed in the testing room. Open book does not mean unlimited materials. A strong study plan uses the same reference book that will be used on exam day and builds comfort with locating information under timed conditions.

Licensing Steps

The ICC Master Plumber - G24-N exam may be used as part of a trade licensing, contractor licensing, or jurisdictional qualification process. The exam itself does not issue a license, business registration, permit privilege, employment authorization, or government approval. Licensing requirements are controlled by the state, county, city, municipality, agency, board, or jurisdiction requiring the exam.

A typical path begins by confirming that the G24-N Master Plumber exam is the correct exam for the license classification or qualification being pursued. The licensing authority may specify the required exam, accepted reference, application documents, trade experience, supervised work history, business registration, insurance, bonding, financial responsibility, background requirements, continuing education, or additional law and business exams.

After confirming the requirement, candidates generally prepare using the approved reference, submit any required application to the licensing authority, receive approval when required, register for the exam through the required testing process, take the exam, and submit proof of passing when requested. Some licensing authorities require candidates to pass both a trade exam and a business or law exam before a license or qualification can be issued.

Candidates pursuing master plumber recognition should understand that licensing is separate from exam preparation. Passing the G24-N exam may satisfy one testing requirement, but the licensing authority determines whether the candidate meets all qualifications. This book package supports exam preparation using the listed reference, but candidates must complete all licensing steps required by the applicable authority.

State Requirements

Master plumber requirements vary by state, county, city, municipality, licensing board, and local authority. Some jurisdictions use ICC exams as part of the licensing process. Others require state-specific exams, local exams, separate business and law exams, documented trade experience, supervised work history, financial responsibility, insurance, bonding, continuing education, business registration, or additional approvals.

The G24-N Master Plumber exam may be accepted in one jurisdiction and not accepted in another. Some licensing authorities require a specific ICC exam code, while others use their own plumbing trade exam or a different code edition. The authority having jurisdiction determines which exam applies, which reference book is allowed, what passing score is required, and what additional requirements must be completed before a license or qualification is issued.

Candidates should check with the licensing board, contractor board, building department, plumbing board, municipality, county, state agency, or employer connected to the license or qualification they are pursuing. That organization determines whether the ICC Master Plumber - G24-N exam applies and how the exam fits into the full licensing process.

Reference Books

• International Plumbing Code, 2018
  The 2018 International Plumbing Code supports preparation for plumbing trade topics that may appear on the ICC Master Plumber - G24-N exam. Candidates should study administration, definitions, general regulations, fixtures, fixture fittings, water heaters, water supply and distribution, sanitary drainage, indirect and special waste, vents, traps, interceptors, separators, storm drainage, piping materials, joints, connections, testing, tables, figures, footnotes, and exceptions.

Test Information and Study Materials

Effective preparation for the ICC Master Plumber - G24-N exam should begin with reference navigation. Candidates should learn the structure of the 2018 International Plumbing Code, including the table of contents, index, chapter organization, definitions, tables, figures, footnotes, and exceptions. The exam requires candidates to find information quickly and apply it correctly to plumbing trade scenarios.

General plumbing regulations are an important starting point. Candidates should review installation requirements, protection of piping, cutting and notching considerations, trenching and backfilling, pipe support, hangers, sleeves, system identification, prohibited locations, testing, inspection, and general safety provisions. Master-level questions may connect these requirements to real field conditions involving pipe installation, system layout, code-compliant workmanship, and inspection readiness.

Plumbing fixtures and fixture fittings should receive focused study. Candidates should review fixture requirements, fixture connections, fixture spacing, accessibility-related fixture provisions where applicable, faucets, shower valves, water closets, urinals, lavatories, sinks, bathtubs, showers, floor drains, drinking fountains, service sinks, and related installation requirements. Fixture questions may require candidates to identify minimum requirements, proper connections, or code-compliant installation conditions.

Water supply and distribution are central plumbing exam topics. Candidates should review water service pipe, distribution pipe, pipe sizing concepts, water pressure, hot water distribution, protection from contamination, backflow prevention, cross-connection control, valves, joints, fittings, pipe materials, support, thermal expansion, and water heater-related provisions. Questions may ask candidates to locate the required protection method or determine whether a water distribution installation meets code.

Sanitary drainage should be studied in detail. Candidates should review fixture units, drainage pipe sizing, drainage slope, branch drains, building drains, building sewers, offsets, cleanouts, changes in direction, materials, joints, supports, backwater valves, and testing. Drainage questions often require careful table use and attention to pipe size, slope, fixture load, developed length, and system arrangement.

Venting is one of the most important study areas for master plumber preparation. Candidates should review vent requirements, vent terminals, vent pipe sizing, individual vents, common vents, wet vents, circuit vents, combination waste and vent systems, island fixture vents, relief vents, stack vents, vent stacks, and distance limits where applicable. Venting questions can be challenging because they may depend on fixture type, drainage arrangement, pipe size, distance, and the specific venting method used.

Traps, interceptors, and separators should also be included in the study plan. Candidates should review trap seal requirements, prohibited traps, trap arms, cleanout access, grease interceptors, oil separators, sand interceptors, and special waste provisions. These topics may appear in questions involving commercial kitchens, garages, floor drains, fixtures, and waste streams that require additional protection before entering the drainage system.

Indirect waste and special waste topics should be reviewed carefully. Candidates should understand air gaps, air breaks, receptor requirements, waste connections from appliances or equipment, food-handling equipment, condensate disposal, chemical waste, and related protection requirements. Questions may describe a piece of equipment and ask how its waste piping must connect to the plumbing system.

Storm drainage preparation should include roof drains, secondary drainage, overflow drainage, scuppers, leaders, conductors, storm drainage pipe sizing, rainfall-based sizing concepts, and related tables. Master plumber candidates should be able to locate storm drainage provisions and understand how roof drainage requirements protect buildings from water accumulation and overflow problems.

Pipe materials, joints, and connections are important throughout the plumbing code. Candidates should study approved materials for water, drainage, vent, storm, and special waste systems. They should also review joining methods, transition fittings, support requirements, protection from corrosion, thermal expansion, and installation limitations. Material questions often require candidates to locate a specific chapter or table and apply it to the correct system type.

Testing and inspection topics should receive careful attention. Candidates should review required tests, test procedures, inspection requirements, system approval, concealment limitations, and what must happen before plumbing systems are placed into service. Master-level candidates should understand how testing relates to code compliance and field quality control.

Definitions are important across the plumbing code. Candidates should practice looking up key terms because exam questions often depend on the code meaning of a word. Terms related to fixtures, drainage, vents, traps, cleanouts, indirect waste, backflow, backwater valves, developed length, fixture units, building drains, building sewers, storm drainage, and potable water can affect how a question should be answered.

Master-level preparation should also include system coordination. Plumbing systems must be designed, installed, tested, and inspected as complete systems. Candidates should practice connecting fixture requirements to water distribution, drainage, venting, trap protection, pipe materials, backflow protection, and testing. A question may appear to be about one subject but depend on several related provisions.

Timed practice is important for this exam. Candidates should practice answering questions while using the highlighted and tabbed reference in a realistic way. Some questions may be answered quickly from a known section, while others may require checking a table, reviewing definitions, comparing multiple sections, or reading an exception. The ability to move efficiently through the book can make a significant difference during open book testing.

A strong study plan combines code reading, topic-based review, reference navigation, and exam-style questions. Candidates should study one subject at a time, locate the related IPC sections, review the applicable tables and definitions, and practice applying reference language to trade scenarios. Field experience is valuable, but exam success depends on using the listed reference accurately and efficiently.
