Exam Details

The Arizona Solar Plumbing, Liquid Systems Only Residential / Commercial Contractor (CR-78) exam is a trade-focused contractor examination for candidates pursuing the Arizona residential and commercial solar plumbing, liquid systems only, classification. Candidates should prepare for technical content related to solar water heating, solar pool heating, liquid-based system circulation, piping, pumps, controls, plumbing code, mechanical code, pipe trades calculations, safety practices, installation methods, and system coordination.

The Code of Federal Regulations - 29 CFR Part 1926 supports preparation for OSHA construction safety requirements. Solar plumbing contractors may work around roof areas, ladders, piping systems, mechanical equipment, pumps, pressurized components, tools, piping materials, hot water systems, trenches, equipment pads, and active construction jobsites. Safety preparation helps candidates review hazard awareness, worker protection, personal protective equipment, ladder safety, fall protection, tool safety, material handling, and safe construction-site practices.

The International Plumbing Code, 2018 supports preparation for plumbing system concepts that may connect to liquid-based solar systems. Candidates should become familiar with code organization, definitions, water distribution, piping materials, joints, valves, testing, installation requirements, fixtures, pipe sizing concepts, and plumbing system coordination. Solar plumbing work often connects with plumbing systems, so candidates should know how to navigate plumbing code references efficiently.

The International Mechanical Code, 2018 supports preparation for mechanical system concepts related to equipment, hydronic-style systems, pumps, piping, heat transfer equipment, appliances, ventilation concepts, and mechanical code organization. Candidates preparing for solar plumbing liquid systems should be comfortable reviewing mechanical system language, equipment requirements, piping-related provisions, and code navigation.

Mathematics for Plumbers and Pipefitters, 8th edition supports preparation for trade calculations. Candidates should review measurements, conversions, slopes, offsets, angles, volumes, areas, pipe measurements, and calculations used in plumbing and pipefitting work. Solar plumbing candidates may need strong math skills to work through piping layout, system measurements, field calculations, and practical installation questions.

IPT’s Pipe Trades Handbook by Robert A. Lee, 2016 supports pipe trades reference knowledge, including piping data, fittings, materials, measurements, conversions, formulas, valves, flanges, threading, and practical field information. This handbook helps candidates connect solar plumbing work to pipe trades fundamentals.

Open Book Test

The Arizona CR-78 Solar Plumbing, Liquid Systems Only Residential / Commercial Contractor exam is an open-book exam. Open-book testing allows approved references to be used during the exam, but candidates still need to prepare carefully. The exam format rewards candidates who understand solar plumbing work, know the references, and can locate information quickly while working under time limits.

For this exam path, candidates should become familiar with each listed reference before test day. Open-book preparation should include learning each book’s table of contents, index, chapter layout, definitions, tables, diagrams, illustrations, code sections, safety sections, and major topic areas. Candidates should not wait until the exam date to begin using the references.

Solar plumbing questions may require candidates to identify OSHA safety requirements, apply plumbing code concepts, locate mechanical code information, complete pipe trades calculations, interpret piping data, evaluate system layout, review solar pool heating concepts, or answer questions about solar water heating components. Strong preparation means knowing the subject well enough to identify the correct topic and knowing the books well enough to locate supporting information quickly.

Open-book does not mean the answers will be easy to find. A candidate who is unfamiliar with the references may lose valuable time searching through the wrong section or using the wrong book. A prepared candidate can recognize the type of question, choose the most useful reference, move to the right section, and apply the information with confidence.

Candidates should practice with the references under timed conditions. A helpful study routine includes reviewing major code chapters, locating common plumbing and mechanical topics, using indexes, reading tables, practicing pipe trades calculations, studying solar system diagrams, and connecting field experience to the listed books. This type of preparation is especially important for a solar plumbing exam because the reference set covers safety, codes, math, pipe trades information, and solar water and pool heating systems.

Licensing Steps

The Arizona contractor licensing process is handled through the Arizona Registrar of Contractors. Candidates pursuing the CR-78 Solar Plumbing, Liquid Systems Only Residential / Commercial Contractor classification should begin by confirming that the CR-78 classification matches the type of residential and commercial solar plumbing liquid systems work they intend to perform.

After confirming the classification, candidates should prepare for the required contractor examination process. This Ultimate package supports CR-78 trade exam preparation through the listed rental references and 1 year of course access. A strong study schedule should cover OSHA construction safety, plumbing code concepts, mechanical code concepts, pipe trades math, piping data, valves, fittings, pumps, solar water heating, solar pool heating, liquid-based circulation systems, layout, installation methods, and system troubleshooting awareness.

Once candidates are ready to test, they must follow the current examination registration process through the approved testing system. After completing the required examinations, the licensing process continues with the Arizona Registrar of Contractors application. The application stage may involve business information, qualifying party information, license classification selection, financial or bonding items, background-related documentation, and other state-required materials.

This Ultimate package includes Application Service to help candidates stay organized during the licensing application process. Application Service supports the paperwork side of the licensing path after exam preparation, helping candidates move from study preparation into application readiness with a clearer structure.

A complete licensing plan should include both exam preparation and application preparation. Candidates should study consistently, organize their references, review the classification requirements, and stay focused on the full licensing process rather than only the test date. This package supports that path with rental books, course access, and Application Service.

State Requirements

The Arizona Registrar of Contractors licenses and regulates contractor classifications in Arizona. Arizona issues separate licenses for commercial and residential work, along with dual classifications that cover both commercial and residential work for a particular trade or field. The CR-78 Solar Plumbing, Liquid Systems Only classification is the dual residential and commercial solar plumbing, liquid systems only, contractor classification.

The CR-78 classification supports contractors preparing to perform solar plumbing work involving liquid-based systems in both residential and commercial settings. This type of work may involve solar water heating, solar pool heating, piping, pumps, valves, controls, circulation systems, liquid-based heat transfer, equipment connections, and related installation work within the permitted scope of the classification.

Arizona contractor licensing is separate from trade experience, employment history, or purchasing exam preparation materials. Candidates must complete the applicable state licensing process before performing regulated contracting work as a licensed contractor. That process may include examination requirements, application documents, qualifying party information, business details, bonding or financial requirements, and other documentation required by the state.

This package supports the exam preparation side with the listed books and 1 year of course access. It also supports the licensing paperwork stage with Application Service. Together, these package elements help candidates prepare for the CR-78 trade exam and stay organized as they work toward the Arizona solar plumbing, liquid systems only, contractor licensing goal.
