Exam Details

The Arizona Plumbing, Including Solar Residential / Commercial Contractor (CR-77) exam is connected to the dual residential and commercial plumbing, including solar, classification. The C-77 / CR-77 Plumbing, Including Solar examination includes a plumbing portion and a solar portion. The plumbing exam contains 100 questions, allows 240 minutes, and requires a 70% minimum passing score. The solar exam contains 30 questions, allows 75 minutes, and requires a 70% minimum passing score.

Students preparing for the CR-77 exam should expect a broad range of plumbing and solar-related trade topics. Plumbing preparation may include drainage, waste and vents, indirect waste, water supply systems, backflow prevention, roof drains and storm drainage systems, plumbing fixtures, water heaters, accessibility, general plumbing knowledge, specialty plumbing, interceptors and traps, fuel gas, septic and sewer, hydronics, fire sprinklers, excavation, and construction safety.

Solar-related plumbing preparation should be approached through the lens of plumbing systems that involve water heating, piping, tanks, pressure, controls, system components, and related installation knowledge. The CR-77 classification includes plumbing, including solar, so students should be prepared to connect plumbing trade knowledge with solar water heating and hydronic concepts where applicable.

The listed references support a wide preparation base. The International Plumbing Code supports core plumbing code topics. The International Fuel Gas Code supports gas piping, appliance connections, combustion air, venting, and fuel gas safety. The International Mechanical Code supports mechanical systems, hydronic concepts, ventilation, and equipment-related code requirements. OSHA 29 CFR Part 1926 supports construction safety, while the Arizona 811 - Arizona Blue Stake Brochure supports underground utility awareness and safe digging practices.

The NFPA sprinkler references support fire sprinkler topics. The Arizona wastewater reference supports septic and on-site wastewater preparation. Mathematics for Plumbers and Pipefitters and IPT’s Pipe Trades Handbook support calculations, piping data, formulas, conversions, and practical trade information. Boiler Operator’s Guide and Modern Hydronic Heating for Residential and Light Commercial Buildings help support boiler, heating, hydronic, and solar-related plumbing study areas.

Open Book Test

The Arizona Plumbing, Including Solar Residential / Commercial Contractor (CR-77) exam is an open-book test. Approved references may be used during the exam, and students should prepare by learning how to navigate the books before test day. Open book does not mean the exam is simple. The exam still requires trade knowledge, code familiarity, good time management, and the ability to locate answers efficiently.

Reference materials can be valuable only when students know how to use them. During preparation, students should become familiar with each book’s table of contents, index, definitions, chapter structure, charts, tables, and key subject areas. A drainage question may lead to the International Plumbing Code. A fuel gas question may lead to the International Fuel Gas Code. A safety question may require OSHA. A septic or wastewater question may require the Arizona Administrative Code wastewater reference. A hydronic or boiler question may require the mechanical, boiler, or hydronic heating references.

Because this package includes a large reference set, students should avoid waiting until the last minute to open the books. The best study approach is steady practice. Students should work through the course, review each reference, practice finding topics, and build a repeatable method for answering open-book questions. Speed and accuracy both matter. The more familiar students become with the books, the more confident they can feel when moving through the exam.

Licensing Steps

Arizona contractor licensing is handled through the Arizona Registrar of Contractors. Contractors pursuing the CR-77 Plumbing, Including Solar classification should follow the state licensing process for the correct license classification and business structure. The CR-77 classification is a dual residential and commercial classification, so it is important to match the license path to the type of work the contractor plans to perform.

A practical licensing path begins with confirming that CR-77 is the correct classification. The applicant then identifies the qualifying party for the license. The qualifying party is the person who demonstrates the required trade knowledge and experience connected to the classification. From there, the applicant follows Arizona ROC instructions for the application, business information, ownership structure, required documents, and any additional requirements that apply to the license.

Exam preparation should begin early because the CR-77 exam covers multiple subject areas and uses several references. Students who begin studying with the books ahead of time have more opportunity to build code familiarity, practice calculations, review trade concepts, and improve reference-navigation speed. This rental package supports that process with 6 months of course access and the listed books for hands-on study.

Passing an exam and receiving license approval are separate parts of the licensing process. This package supports preparation for the Arizona Plumbing, Including Solar Residential / Commercial Contractor (CR-77) exam. License approval is handled by the Arizona Registrar of Contractors and depends on the applicant’s complete file, qualifications, and compliance with state requirements.

State Requirements

The Arizona Registrar of Contractors regulates contractor licensing in Arizona. The CR-77 Plumbing, Including Solar classification is associated with residential and commercial plumbing work, including solar-related plumbing work within the classification scope. Contractors pursuing this classification should be prepared to follow Arizona ROC licensing rules, complete the required application materials, and comply with the requirements that apply to licensed contractors in the state.

The CR-77 scope includes plumbing work connected to piping, fixtures, appliances, water supply, pressure vessels and tanks, venting, sanitary drainage systems, septic tanks and leaching lines, roof leaders, lawn sprinkler systems, water conditioning equipment, swimming pool piping and equipment, gas piping, piping for steam, hot water heating, hot water supply, chilled water, compressed air, vacuum systems, and related plumbing work within the limits of the classification.

Because the classification includes solar, students should also be prepared for plumbing-related solar knowledge connected to water heating systems, piping, tanks, hydronic principles, and system components. A strong preparation plan should include both traditional plumbing code review and solar-related plumbing concepts, especially where solar water heating and hydronic heating knowledge overlap.
