It can be used alongside approved reference books, highlighted and tabbed materials, classroom instruction, field experience, or independent study. The goal is to help you prepare with structure instead of reading through plumbing code, fuel gas code, mechanical code, sprinkler standards, wastewater rules, hydronic heating, pipe trades, and safety references without a clear plan.\u003c\/p\u003e\n\n\u003cp\u003ePlumbing, including solar, can include piping, fixtures, appliances, water supply systems, sanitary drainage, venting, indirect waste, traps, interceptors, backflow prevention, storm drainage, fuel gas piping, septic systems, sewer lines, fire sprinkler piping, hydronic systems, excavation, solar water heating connections, and jobsite safety. Because the CR-77 classification covers both residential and commercial work, candidates should prepare for the full range of plumbing exam topics rather than focusing only on one type of system.\u003c\/p\u003e\n\n\u003ch2 style=\"color: #d32f2f;\"\u003eWhat You Get\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOnline Practice Questions:\u003c\/strong\u003e Trade-focused questions designed to support preparation for the Arizona Plumbing, Including Solar Residential\/Commercial Contractor (CR-77) exam.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3 Months of Access:\u003c\/strong\u003e Study online with 3 months of access so you can review, repeat, and strengthen your preparation over time.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePlumbing Code Review:\u003c\/strong\u003e Practice content supports review of drain-waste-vent systems, water supply, backflow, fixtures, water heaters, storm drainage, indirect waste, traps, interceptors, septic, sewer, and excavation.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuel Gas and Mechanical Support:\u003c\/strong\u003e Questions help reinforce International Fuel Gas Code and International Mechanical Code topics connected to plumbing, fuel gas piping, appliances, hydronics, and related systems.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFire Sprinkler, Hydronic, and Solar Plumbing Support:\u003c\/strong\u003e Practice helps candidates review NFPA sprinkler standards, hydronic heating concepts, pipe trades information, boiler topics, and solar plumbing awareness.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelf-Paced Study Format:\u003c\/strong\u003e Work through questions on your own schedule and return to subjects that need additional review.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2 style=\"color: #d32f2f;\"\u003eExam Details\u003c\/h2\u003e\n\n\u003cp\u003eThe Arizona CR-77 Plumbing, Including Solar Residential\/Commercial Contractor exam preparation should focus on the plumbing trade areas tied to the classification, including DWV systems, water supply, backflow, roof drains and storm drainage, plumbing fixtures, water heaters, accessibility, general plumbing knowledge, specialty plumbing, fuel gas, septic and sewer, hydronics, fire sprinklers, excavation, and solar plumbing topics connected to the license scope.\u003c\/p\u003e\n\n\u003cp\u003eThe plumbing portion of this exam preparation includes DWV systems, indirect waste, water supply, backflow, roof drains and storm drainage, plumbing fixtures, water heaters, accessibility, specialty plumbing, fuel gas, septic and sewer, hydronics, fire sprinklers, and excavation. Candidates should give extra attention to the International Plumbing Code, International Fuel Gas Code, International Mechanical Code, OSHA safety standards, and the NFPA sprinkler standards because these references support many of the technical topics tied to plumbing work.\u003c\/p\u003e\n\n\u003cp\u003eSince this classification includes solar, candidates should also be prepared for plumbing-related solar concepts such as solar water heating system piping, collector and storage awareness, pumps, valves, controls, pipe materials, open and closed loop awareness, system protection, water heater connections, hydronic relationships, and safe installation practices. Solar-related preparation should be studied as part of the broader plumbing scope and connected back to code, piping, water heating, hydronics, and system safety.\u003c\/p\u003e\n\n\u003cp\u003eBecause this is a contractor trade exam, candidates should prepare for both accuracy and pacing.

Candidates are responsible for bringing their own approved references to the examination center. The approved exam-room references include 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.\u003c\/p\u003e\n\n\u003cp\u003eThe study references used for preparation include Mathematics for Plumbers and Pipefitters, 8th edition; IPT’s Pipe Trades Handbook, Robert A.

For plumbing, including solar, in both residential and commercial settings, the relevant classification is CR-77 Plumbing, Including Solar Residential\/Commercial.\u003c\/p\u003e\n\n\u003cp\u003eAfter selecting the correct classification, candidates should review the examination requirements tied to that license. The CR-77 trade exam is one part of the licensing process. Contractor applicants may also need to complete the Arizona business management or statutes and rules requirement, application requirements, qualifying party requirements, bonding requirements, experience requirements, and other items required by the Arizona Registrar of Contractors.\u003c\/p\u003e\n\n\u003cp\u003eA practical licensing plan separates exam preparation from application preparation. Exam preparation focuses on plumbing code, fuel gas code, mechanical code, DWV systems, water supply, fixtures, backflow, storm drainage, septic and sewer, hydronics, fire sprinklers, excavation, pipe trades math, solar plumbing awareness, and OSHA safety. Application preparation focuses on state forms, business structure, qualifying party information, bond requirements, fees, and supporting documents.\u003c\/p\u003e\n\n\u003cp\u003eUsing online practice questions during the exam preparation phase gives structure to your study time. Questions help reveal which subjects are already familiar and which ones need more review. This makes it easier to use the 3-month access period productively and keeps preparation focused on the subjects most closely tied to the CR-77 plumbing, including solar, exam.\u003c\/p\u003e\n\n\u003ch2 style=\"color: #d32f2f;\"\u003eState Requirements\u003c\/h2\u003e\n\n\u003cp\u003eThe Arizona Registrar of Contractors issues contractor licenses by classification. Commercial classifications apply to commercial work, residential classifications apply to residential work, and dual classifications may apply when a contractor qualifies for both commercial and residential work. The CR-77 classification is the residential\/commercial plumbing, including solar, contractor classification.\u003c\/p\u003e\n\n\u003cp\u003eThe plumbing, including solar, classification includes installation, alteration, and repair of plumbing within property lines, including solar when performed within the license scope. This may include piping, fixtures, appliances, water supply systems, pressure vessels and tanks excluding municipal systems, venting and sanitary drainage systems, septic tanks, leaching lines, roof leaders, lawn sprinkler systems, water conditioning equipment, and piping and equipment for swimming pools.\u003c\/p\u003e\n\n\u003cp\u003eThe classification may also include piping for gas, compressed air, vacuum, petroleum, fuel oil, non-potable liquids, hot water heating systems, steam systems within classification limits, water cooling systems excluding refrigerant piping and equipment, and testing and balancing of hydronic systems. Plumbing work may also involve sewer, gas, and water lines to the nearest public supply or disposal system when performed within the limits allowed by the classification.\u003c\/p\u003e\n\n\u003cp\u003eResidential\/commercial plumbing including solar contractors should understand where the classification begins and ends. Work outside the license classification may require another properly licensed contractor. Passing the trade exam is not the same as receiving a license.
