The solar manual supports solar water and pool heating concepts. Together, the references create a focused study library for the C-78 commercial exam.

Exam Details

Arizona contractor trade examinations are administered through PSI for the Arizona Registrar of Contractors. The C-78 Solar Plumbing, Liquid System Only classification is a commercial contractor classification tied to solar plumbing liquid systems. Students preparing for this exam should focus on solar water heating systems, liquid-based solar systems, solar pool heating, plumbing code, mechanical code, OSHA construction safety, pipe trade calculations, pipe system components, and practical installation knowledge.

The exam is based on trade knowledge and approved reference materials. Students should be prepared for questions involving construction safety, plumbing code requirements, mechanical code requirements, solar water heating design, solar pool heating design, liquid system piping, valves, pumps, heat transfer, system layout, pipe trade math, fittings, supports, installation practices, troubleshooting concepts, and jobsite safety. Because C-78 is a commercial classification, preparation should focus on commercial solar plumbing liquid system work.

PSI contractor exams are computer-based. Candidates answer questions on screen and use approved reference materials during the exam. This testing format requires both trade understanding and reference-navigation skill. Students should prepare by learning the material, practicing exam-style questions, and becoming familiar with the organization of each book in the reference set.

Arizona contractor licensing may also require the Arizona Statutes and Rules Exam, depending on the applicant and qualifying party requirements. The trade exam is one part of the licensing process. Passing an exam does not automatically issue a contractor license. Applicants must still complete the Arizona Registrar of Contractors application process and satisfy the requirements that apply to the C-78 commercial classification.

Open Book Test

The Arizona C-78 Solar Plumbing, Liquid System Only commercial contractor trade exam is an open-book style exam using approved references. Open-book testing gives candidates access to reference materials during the exam, but it still requires careful preparation. Students need to understand the trade, recognize which reference applies to a question, and locate information efficiently while working under timed conditions.

Each reference in this package serves a specific study purpose. OSHA 29 CFR Part 1926 supports construction safety topics. The International Plumbing Code supports plumbing code requirements. The International Mechanical Code supports mechanical code topics. Mathematics for Plumbers and Pipefitters supports trade math, formulas, measurements, offsets, and calculation practice. IPT’s Pipe Trades Handbook supports pipe, fittings, valves, flanges, materials, symbols, and pipe trade reference data. Solar Water and Pool Heating Design and Installation Manual supports solar water heating and solar pool heating system concepts.

Students should practice recognizing the correct book before searching for an answer. A safety question may belong in OSHA. A code question may belong in the International Plumbing Code or International Mechanical Code. A calculation question may require Mathematics for Plumbers and Pipefitters. A pipe component or fitting question may point toward IPT’s Pipe Trades Handbook. A solar heating question may require the Solar Water and Pool Heating Design and Installation Manual.

Book organization matters. Students should become familiar with each book’s table of contents, index, chapter layout, terminology, tables, diagrams, definitions, and common subject areas. When permitted by testing rules, permanent tabs can help speed up navigation. A useful tabbing system should be simple, clean, and focused on major exam topics rather than overloaded with unnecessary labels.

Licensing Steps

The Arizona C-78 licensing path begins with selecting the correct contractor classification. C-78 is the commercial classification for Solar Plumbing, Liquid System Only. It is intended for commercial solar plumbing liquid system work within the scope of the classification.

After identifying the correct classification, the qualifying party prepares for the required examination path. This may include the C-78 trade examination and the Arizona Statutes and Rules Exam. Candidates should study from the approved references connected to the classification and follow the current scheduling process through the approved testing provider.

Once examination requirements are completed, the applicant moves forward with the Arizona Registrar of Contractors license application. The application process may include business information, qualifying party information, financial responsibility requirements, bonding, background-related requirements, fees, and other supporting documentation required by the state. The exact application requirements depend on the applicant, entity type, qualifying party status, and license classification.

Starting preparation early helps students build a stronger routine. With 6 months of course access, candidates can review lessons, study the books, work through practice questions, revisit difficult areas, and improve reference-navigation speed before exam day. This approach is especially useful for contractors who understand field work but need to prepare for the structure and pace of a licensing exam.

State Requirements

The Arizona Registrar of Contractors issues commercial, residential, and dual contractor licenses. The C-78 Solar Plumbing, Liquid System Only classification is a commercial classification. It is focused on solar plumbing liquid systems and does not serve as a general plumbing, electrical, or mechanical license.

The C-78 commercial scope allows the licensee to install, alter, and repair solar water heating systems operating at temperatures not exceeding 220 degrees Fahrenheit, including thermosyphon, direct open-loop, and indirect closed-loop systems, but excludes air as a transfer medium. The scope also includes installation of solar heating systems for swimming pools that tie into and operate from the conventional pool system, while excluding non-solar plumbing, electrical, and mechanical systems and components.

Students preparing for C-78 should focus on solar plumbing liquid systems rather than unrelated trade work. Study areas may include solar water heating, liquid transfer systems, system piping, valves, pumps, low-voltage controls connected to existing stub-outs, plumbing code, mechanical code, OSHA safety, solar pool heating, and pipe trade calculations.

Arizona licensing approval is separate from exam preparation. The state determines whether an applicant qualifies for the license, whether the qualifying party requirements have been met, and whether the application is complete. This package supports exam preparation, but applicants must still follow the Arizona Registrar of Contractors licensing process and satisfy the requirements that apply to the C-78 classification.

Test Information and Study Materials

Effective C-78 preparation should combine trade review, code study, math practice, solar system review, and open-book navigation. Students should begin by learning what each reference is used for. OSHA supports safety topics. The International Plumbing Code supports plumbing code questions. The International Mechanical Code supports mechanical code questions. Mathematics for Plumbers and Pipefitters supports calculation practice. IPT’s Pipe Trades Handbook supports pipe trade reference data. Solar Water and Pool Heating Design and Installation Manual supports solar water and pool heating topics.

For safety topics, spend time with the OSHA construction standards. Solar plumbing work can involve ladders, roof-adjacent work, equipment handling, pipe installation, material handling, excavation-related work, and general jobsite hazards. Safety questions can be direct, so students should practice finding OSHA rules quickly.

For code topics, separate plumbing and mechanical study time. The International Plumbing Code and International Mechanical Code are large references, and students should practice finding definitions, chapters, tables, material requirements, system requirements, and installation provisions before test day. Code questions often depend on knowing where to look, not just knowing the general concept.

For math topics, review the calculations used in plumbing and pipefitting. Students should be comfortable with fractions, decimals, measurements, offsets, area, volume, basic geometry, pipe-related calculations, and formula use. Math confidence can save time during the exam and reduce second-guessing when a question requires a calculated answer.

For pipe trade topics, use IPT’s Pipe Trades Handbook to review fittings, valves, pipe materials, dimensions, symbols, flanges, threads, and reference tables. Solar plumbing liquid systems depend on correct pipe layout, system components, and installation details. Knowing how to find reference data quickly can help with both exam preparation and trade understanding.

For solar topics, focus on liquid-based solar water and pool heating systems. Students should review collectors, piping layouts, pumps, valves, controls, heat transfer, direct and indirect systems, open-loop and closed-loop systems, thermosyphon principles, freeze protection concepts, system operation, and troubleshooting. The solar manual should be used consistently throughout the study process because it ties the trade scope together.

Practice should include timed book-navigation drills. When answering a practice question, decide which reference applies before opening the book. Then use the table of contents, index, headings, tabs, and familiar sections to find the answer. This process builds the speed needed for an open-book contractor exam.

A steady study schedule is usually more effective than last-minute cramming. With 6 months of course access, students can build a routine that includes lesson review, reference reading, practice questions, math review, code navigation, solar system review, and repeated exam-style practice. Consistency helps make the reference set less overwhelming and gives students more time to strengthen weak areas before test day.
