Exam Details

The Arizona Plumbing, Including Solar Residential Contractor (R-37) exam path includes the residential plumbing trade exam and a solar-related exam component. Candidates should prepare for plumbing code requirements, fuel gas code requirements, mechanical code topics, residential sprinkler provisions, wastewater treatment rules, construction safety, and solar system piping. This combination of topics makes R-37 preparation broader than a basic plumbing review.

Plumbing exam preparation should include water distribution, drainage, waste and vent systems, fixtures, traps, cleanouts, pipe materials, fittings, valves, supports, installation methods, testing, inspection, and code compliance. Candidates should also review fuel gas piping, appliance connections, combustion air, venting, mechanical system coordination, and safety requirements that may connect to residential plumbing work.

Because this license includes solar, candidates should also prepare for solar system topics such as collection loops, components, installation, maintenance, mounting, principles, and solar systems piping. Solar-related questions may require understanding how piping, water systems, and mechanical components work together in a residential system.

The exam-room-approved references in this package support different parts of the preparation process. The International Plumbing Code, 2018 supports core plumbing code review. The International Fuel Gas Code, 2018 supports gas piping, appliance, combustion air, and venting topics. The International Mechanical Code, 2018 supports mechanical system requirements that may connect to plumbing and solar work. OSHA 29 CFR Part 1926 supports construction safety and employee protection.

The NFPA sprinkler references support sprinkler system preparation. NFPA 13 covers installation of sprinkler systems, NFPA 13D focuses on sprinkler systems in one- and two-family dwellings and manufactured homes, and NFPA 13R applies to sprinkler systems for residential occupancies up to and including four stories in height. Candidates should understand the purpose of each sprinkler reference and practice finding information in the correct book.

The Arizona Administrative Code Title 18, Chapter 9 wastewater reference supports review of on-site wastewater treatment facility provisions. This is important for candidates preparing for residential plumbing work involving wastewater-related rules and code-based requirements. Candidates should practice locating definitions, provisions, and requirements within the reference before test day.

Open Book Test

The Arizona R-37 Plumbing, Including Solar residential 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 Fuel Gas Code, 2018, International Mechanical Code, 2018, International Plumbing Code, 2018, NFPA 13: Installation of Sprinkler Systems, 2019, NFPA 13D - Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes, 2019, NFPA 13R - Sprinkler Systems for Residential Occupancies up to and Including Four Stories in Height, 2019, and On-site Wastewater Treatment Facility Provisions in Unified Water Quality Permit Rule, Arizona Administrative Code Title 18, Chapter 9, 2006.

Open book does not mean the exam is easy. Candidates must be able to identify the subject being tested, choose the correct reference, locate information efficiently, and apply the answer to the question. The approved books are most useful when the candidate has practiced using them before the exam.

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 every reference in the package. Plumbing questions may require the International Plumbing Code. Fuel gas questions may require the International Fuel Gas Code. Mechanical or solar-related questions may require the International Mechanical Code. Sprinkler questions may require NFPA 13, NFPA 13D, or NFPA 13R. Wastewater questions may require the Arizona Administrative Code wastewater provisions, and safety questions may require OSHA 29 CFR Part 1926.

Licensing Steps

Arizona contractor licensing is regulated by the Arizona Registrar of Contractors. Candidates pursuing the R-37 Plumbing, Including Solar residential 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 R-37 classification matches the work the contractor intends to perform. Arizona contractor licenses are classification-specific, so selecting the correct classification is important. The R-37 classification is intended for residential plumbing work, including solar-related plumbing scope within the classification.

After confirming the correct classification, candidates should prepare for the exam path by studying the exam content areas, reviewing the approved references, practicing book navigation, and building familiarity with plumbing code requirements, fuel gas provisions, mechanical system topics, sprinkler systems, wastewater rules, solar piping, 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 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 R-37 Plumbing, Including Solar residential contractor classification is tied to residential plumbing work and includes solar-related plumbing within the permitted scope. Candidates preparing for this classification should understand that the license is residential, which makes it different from a commercial-only plumbing license and different from a dual residential/commercial plumbing classification.

Residential plumbing work may involve water supply systems, drainage systems, venting, fixtures, fuel gas piping, appliance connections, water heaters, solar-related piping, sprinkler-related systems, and wastewater-related requirements within the permitted residential scope. Candidates should prepare with the full classification in mind rather than studying only one area of plumbing.

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.

Plumbing contracting requires attention to safety, sanitation, system performance, water distribution, drainage, venting, fuel gas safety, mechanical coordination, code compliance, inspections, and customer protection. The R-37 exam path is designed to test knowledge connected to these responsibilities and the references used in the trade.

Candidates should prepare with an organized plan that includes reference-book use, trade knowledge review, practice-oriented study, exam timing awareness, and application organization. This Ultimate package supports that approach by combining the approved references, course access, and Application Service into one preparation option.
