What You Get

This package is a practical option for candidates who need access to the full listed reference set for Arizona C-77 preparation but do not want to purchase every book outright. The rental format gives students the books needed for study, while the course access provides structure, review, and practice support throughout the preparation period.

Exam Details

The Arizona Plumbing, Including Solar Commercial Contractor (C-77) exam is part of the Arizona contractor licensing examination process. The Arizona Registrar of Contractors uses PSI to administer the contractor trade examination program. PSI provides examination information, trade content outlines, reference lists, exam rules, scheduling procedures, and testing requirements for Arizona contractor classifications.

The C-77 Plumbing, Including Solar commercial contractor exam includes 100 questions, allows 240 minutes of testing time, and requires a 70% minimum passing score. Candidates preparing for this classification should also be aware that the solar portion may involve a separate solar examination component with its own time limit and question count. Preparation should include plumbing trade knowledge, solar water heating concepts, fuel gas, mechanical systems, fire protection references, wastewater provisions, pipe trade math, boiler concepts, hydronic heating, and OSHA construction safety.

The C-77 exam may include questions based on listed reference materials, trade knowledge, and general industry practices. Code questions are based on the specific code editions listed for the examination. This makes it important to study from the correct editions and to become familiar with the organization of each reference. Plumbing candidates should be comfortable moving through code books, using indexes, reading tables, applying definitions, and reviewing exceptions and notes carefully.

Because the C-77 classification includes commercial plumbing work and solar-related plumbing work, the exam can require preparation across multiple technical areas. Students should expect to study water supply, sanitary drainage, storm drainage, vents, fixtures, traps, interceptors, fuel gas, mechanical systems, boiler-related topics, hydronic systems, fire sprinkler standards, wastewater treatment provisions, utility locating, solar water heating, and construction safety.

Open Book Test

The Arizona C-77 Plumbing, Including Solar commercial contractor exam is an open-book trade exam using approved references. Candidates are responsible for bringing their allowed references to the examination center. This makes book familiarity and reference navigation a major part of exam preparation.

Open-book testing does not remove the need to study. Candidates still need to understand the subject matter, recognize which reference applies to a question, and find information quickly under time pressure. A student who has the correct books but has not practiced with them may lose valuable time searching through unfamiliar chapters, tables, definitions, and indexes.

Students should prepare with the same references included in this package and practice using them regularly. A strong routine includes reviewing a topic, answering practice questions, locating the supporting material in the books, and repeating weak areas until the information becomes easier to find. The goal is to make the references feel familiar before exam day.

Exam references should be prepared according to PSI rules. Reference materials may be highlighted, underlined, annotated, and indexed before the exam session. Candidates should not write in the references during the exam. Additional papers, whether loose or attached, are not allowed with approved references. Permanent tabs may be used, while temporary removable tabs are not allowed. Downloaded references must be bound before being brought into the testing center.

Licensing Steps

Arizona contractor licensing is handled through the Arizona Registrar of Contractors. A candidate pursuing the C-77 Plumbing, Including Solar Commercial Contractor classification should begin by confirming that the C-77 classification matches the commercial plumbing and solar plumbing work the business intends to perform.

The qualifying party is the person responsible for meeting the examination requirements for the license classification. For many applicants, this means passing the required trade examination and completing the Arizona statutes and rules training requirement when applicable. Applicants must also prepare the business and qualifying party information required for the state licensing application.

The general licensing path includes selecting the correct classification, preparing for the required exam, completing the examination process, gathering application documents, and submitting the contractor license application to the Arizona Registrar of Contractors. PSI administers the trade examination program, so candidates should follow PSI procedures for exam registration, scheduling, testing rules, and score reporting.

After testing requirements are complete, the application is reviewed through the Arizona Registrar of Contractors. State approval is separate from exam preparation and depends on the applicant meeting all applicable requirements. This product supports exam preparation by providing the listed rental books and 6 months of course access.

State Requirements

The Arizona Registrar of Contractors issues separate licenses for commercial and residential work, as well as dual classifications that may cover both commercial and residential scopes in a particular trade or field. The C-77 Plumbing, Including Solar classification is a commercial classification for plumbing work, including solar, within the limits of the classification.

The C-77 classification allows installation, alteration, and repair of plumbing, including solar, when performed solely within property lines and not on public easements or rights-of-way except as permitted by the classification. Candidates should understand that the state defines the license scope, and the Arizona Registrar of Contractors determines whether an applicant meets licensing requirements.

Arizona licensing requirements may include trade exam completion, qualifying party requirements, business entity information, application documents, financial or bonding-related requirements, and Arizona statutes and rules training when applicable. Requirements can vary based on the applicant’s business structure, qualifying party status, prior licensing history, and selected classification.

Test Information and Study Materials

Effective preparation for the Arizona C-77 Plumbing, Including Solar exam should include code study, trade math, safety review, and repeated practice with the full reference set. Plumbing exams can be difficult because they combine practical installation knowledge with code-based requirements. Candidates should study each topic area and practice finding answers in the appropriate book.

For plumbing code preparation, students should focus on the 2018 International Plumbing Code. Important study areas include water supply systems, sanitary drainage, storm drainage, venting, fixtures, traps, interceptors, cleanouts, materials, installation requirements, and inspection-related provisions. The IPC includes many tables and definitions, so students should practice locating information quickly and reading table notes carefully.

For fuel gas preparation, the 2018 International Fuel Gas Code should be studied closely. Students should review gas piping, sizing, appliance connections, combustion air, venting, shutoff valves, pressure testing, and installation requirements. Fuel gas questions often require careful reading because the correct answer can depend on the system type, appliance condition, or specific table being used.

For mechanical and hydronic topics, students should use the 2018 International Mechanical Code, Modern Hydronic Heating, Boiler Operator’s Guide, and related pipe trade references. Preparation should include hydronic piping, boilers, pumps, controls, combustion air, venting, system operation, and heating-system components. These topics connect plumbing knowledge with mechanical system understanding.

For solar preparation, students should review solar water heating and solar pool heating concepts. Solar-related plumbing work can involve collectors, storage tanks, piping, pumps, controls, heat transfer, circulation, freeze protection, and installation practices. Candidates should connect solar reference study with practical plumbing and mechanical knowledge.

For fire sprinkler preparation, students should review the NFPA 13, NFPA 13D, and NFPA 13R references included in this package. These standards support study for sprinkler system concepts, occupancy differences, system components, installation rules, and fire protection requirements. Students should understand which sprinkler reference applies to which type of building or occupancy.

For wastewater and excavation-related study, candidates should review the Arizona wastewater provisions and the Arizona 811 Blue Stake Brochure. Plumbing work often involves underground systems, excavation, utility awareness, and site coordination. Understanding safe digging practices and utility-location responsibilities is important for both exam preparation and professional work.

For OSHA safety, students should study 29 CFR Part 1926 for common construction hazards. Plumbing contractors may encounter excavation hazards, confined work areas, ladders, scaffolds, material handling, personal protective equipment, electrical hazards, and jobsite safety responsibilities. OSHA questions often describe a work condition and require the candidate to identify the correct safety practice or rule.

A strong study routine includes reading course lessons, reviewing reference sections, answering practice questions, checking answers in the books, and repeating weak topics. Students should also practice under timed conditions. The C-77 exam allows 240 minutes for 100 questions, so candidates should build a steady pace and learn when to search a reference, when to rely on prepared knowledge, and when to move forward and return to a difficult question later.
