Exam Details

The Arizona Solar Plumbing, Liquid Systems Only Residential / Commercial Contractor (CR-78) trade exam is designed for candidates pursuing a residential/commercial contractor classification connected to solar plumbing liquid systems. Candidates should prepare for liquid-based solar system concepts, plumbing code requirements, mechanical code requirements, pipe installation, system components, construction safety, and open-book reference use.

Solar plumbing preparation should include collection loops, piping arrangements, liquid circulation, system components, valves, fittings, supports, pumps, equipment connections, heat-transfer concepts, water-system coordination, and installation conditions. Candidates should understand how solar plumbing liquid systems operate and how piping, mechanical equipment, and plumbing requirements work together in a complete system.

Because this classification is limited to solar plumbing liquid systems, candidates should focus on the systems and components that relate directly to liquid-based solar heating work. The exam preparation path should not be treated as a general plumbing exam, general mechanical exam, or electrical solar photovoltaic exam. The main focus is solar plumbing liquid systems, with supporting code and safety knowledge.

Plumbing code preparation should include water piping, joints, materials, valves, supports, fittings, drainage-related considerations, testing, and inspection concepts that may apply to solar plumbing system work. The International Plumbing Code, 2018 is the primary reference for plumbing code organization, definitions, requirements, tables, and system rules that may appear in preparation.

Mechanical code preparation should include mechanical equipment, access, installation requirements, ventilation-related awareness, equipment support, combustion air where applicable, system coordination, and mechanical provisions that may connect to solar plumbing liquid systems. The International Mechanical Code, 2018 helps candidates prepare for mechanical code questions and system requirements that may overlap with solar plumbing work.

Safety preparation should include OSHA construction standards, jobsite hazard awareness, personal protective equipment, ladder safety, scaffold safety, fall protection, material handling, tool safety, excavation awareness, and safe work practices. Solar plumbing work may involve rooftops, exterior equipment, pipe handling, pumps, panels, supports, water piping, and jobsite coordination, making safety review an important part of preparation.

Candidates should also practice how to use the approved books. Open-book contractor exams require more than owning the references. Candidates must know how to locate definitions, use the index, read tables, follow exceptions, and confirm answers quickly. The highlighted and tabbed books included in this package are designed to support faster study and exam preparation, but the student should still spend time using the books before exam day.

Open Book Test

The Arizona CR-78 Solar Plumbing, Liquid Systems Only residential/commercial contractor exam is an open book test. Candidates may bring specific approved references into the examination center. The approved references included with this package are Code of Federal Regulations - 29 CFR Part 1926 (OSHA), International Plumbing Code, 2018, and International Mechanical Code, 2018.

Open book does not mean the exam is simple. Candidates must be able to identify the subject being tested, select the correct reference, locate the relevant information, and apply the requirement to the question. The books are most useful when the candidate has practiced using them throughout the study process.

Approved references may be highlighted, underlined, annotated, and indexed before the examination session. Candidates may not write, highlight, underline, or add indexing during the exam. Book preparation should be completed before test day so the materials are ready for use during the timed examination.

References may be tabbed or indexed with permanent tabs only. Permanent tabs are tabs that would tear the page if removed. Temporary tabs, removable sticky notes, loose papers, and extra attached papers are not allowed. This package supports preparation by providing books that are highlighted and tabbed for exam preparation.

For this exam, candidates should practice using each reference in the package. OSHA 29 CFR Part 1926 supports construction safety and employee protection preparation. The International Plumbing Code, 2018 supports plumbing code preparation related to liquid piping, water systems, materials, fittings, valves, supports, and testing concepts. The International Mechanical Code, 2018 supports mechanical system preparation, equipment requirements, system installation, and related mechanical provisions.

Strong open-book preparation includes learning how each book is organized, using the table of contents and index, reading definitions carefully, locating tables, reviewing marked sections, and confirming requirements before selecting an answer. The highlighted and tabbed books included in this package help support reference navigation, but consistent study and practice remain important.

Licensing Steps

Arizona contractor licensing is regulated by the Arizona Registrar of Contractors. Candidates pursuing the CR-78 Solar Plumbing, Liquid Systems Only residential/commercial contractor classification should prepare for the required trade examination and complete the contractor licensing application process connected to the classification.

The licensing process generally begins with confirming that the CR-78 classification matches the work the contractor intends to perform. Arizona contractor licenses are classification-specific, so selecting the correct classification is important. The CR-78 classification is intended for contractors seeking a residential/commercial solar plumbing liquid systems scope.

After confirming the correct classification, candidates should prepare for the trade exam by studying the approved references, reviewing solar plumbing liquid-system concepts, practicing book navigation, and building familiarity with plumbing code requirements, mechanical code topics, system components, installation practices, and construction safety.

The contractor application process may include business information, qualifying party information, documentation, and other licensing materials required for the Arizona contractor license application. This Ultimate package includes Application Service support to help candidates stay organized while working through the licensing process.

Application Service is included because exam preparation and licensing paperwork are both important parts of the contractor licensing goal. Passing the trade exam is a major step, but the application must also be completed properly. Organized application support helps candidates focus on study while keeping the licensing process moving forward.

State Requirements

The Arizona CR-78 Solar Plumbing, Liquid Systems Only classification is tied to residential and commercial solar plumbing liquid systems. The classification is connected to installation of solar heating systems for swimming pools that tie into and operate from the conventional pool system, while excluding all non-solar plumbing, electrical, and mechanical systems and components.

This classification is specialized. Candidates should understand that CR-78 is not a broad plumbing classification, not a broad mechanical classification, and not an electrical solar photovoltaic classification. The focus is liquid-system solar plumbing work within the permitted residential/commercial scope of the license.

State requirements matter because they define the type of contracting work that may be performed under the license. Candidates should prepare for the required examination, use the correct classification, and complete the application process carefully. This package supports both the study side and the application side by combining approved books, course access, highlighted and tabbed references, and Application Service.

Solar plumbing liquid-system work may involve piping, valves, pumps, collectors, supports, connections, system layout, pool-heating system integration, mechanical coordination, plumbing code compliance, testing awareness, and safety. Contractors preparing for this license should understand how the solar liquid-system side of the work fits within the defined classification limits.

Candidates should prepare with the full residential/commercial scope in mind. Residential and commercial projects may involve different system sizes, layouts, equipment locations, access conditions, piping arrangements, and inspection expectations. A complete preparation plan should include trade review, code review, reference-book use, exam timing practice, and application organization.
