The 1 Package: All-Inclusive Arizona Plumbing, Including Solar Residential / Commercial Contractor (CR-77) Exam, Licensing & Business Setup Solution

Prepare for the Arizona Plumbing, Including Solar Residential / Commercial Contractor CR-77 exam while building the licensing and business foundation needed to operate professionally. The 1 Package combines plumbing exam preparation, an extensive technical reference library, contractor application assistance, business formation, EIN filing, and contractor compliance guidance in one organized solution.

This all-inclusive Arizona CR-77 contractor package is designed for experienced plumbers, pipefitters, hydronic-heating professionals, solar thermal installers, plumbing supervisors, qualifying parties, and business owners pursuing residential and commercial plumbing authority in Arizona.

The CR-77 classification combines plumbing work with qualifying solar plumbing systems. Candidates should be prepared to study water distribution, sanitary drainage, venting, fuel gas, fixtures, piping, fire-sprinkler provisions, hydronic heating, boilers, on-site wastewater requirements, solar thermal systems, trade mathematics, excavation safety, and utility-location practices.

Professional plumbing work requires careful coordination among codes, plans, equipment, materials, and field conditions. Contractors must understand how to size and install piping, protect potable water, provide drainage and venting, connect fixtures and equipment, test completed systems, and recognize when mechanical, fuel-gas, fire-sprinkler, wastewater, or solar requirements apply.

The package includes 1 year of course access, allowing candidates to prepare around employment, active projects, and personal responsibilities. The course supports organized subject review, trade calculations, code navigation, practice-oriented preparation, and repeated work with the included plumbing and mechanical references.

The 1 Package also supports the licensing and business stages that follow exam preparation. Application Service helps organize the Arizona contractor licensing process. Business Formation establishes an LLC or corporation, EIN Filing supports banking and tax administration, and Contractor Compliance Guidance helps customers understand responsibilities associated with operating an Arizona residential and commercial plumbing business.

Exam Details

The Arizona Registrar of Contractors licenses and regulates residential, commercial, and dual contractors. The CR-77 Plumbing, Including Solar classification is a specialty dual license covering the authorized residential and commercial plumbing scopes established by Arizona.

The qualifying party is the individual whose experience, knowledge, and examination qualifications support the license. This person must meet the applicable requirements and remain associated with the licensed business in the qualifying capacity recognized by the Arizona Registrar of Contractors.

CR-77 preparation covers a wide range of plumbing knowledge. Subjects may include potable water distribution, sanitary drainage, vent systems, fixtures, traps, interceptors, fuel-gas piping, water heaters, boilers, hydronic systems, fire-sprinkler standards, on-site wastewater provisions, solar thermal plumbing, testing, inspections, mathematics, and OSHA safety.

Water-distribution study may involve service piping, materials, sizing, pressure, valves, backflow protection, water heaters, fixture supply, thermal expansion, insulation, supports, and testing. Candidates should understand how demand, elevation, pressure loss, and piping layout affect system performance.

Drainage and vent preparation may include sanitary building drains, sewers, fixture drains, traps, cleanouts, vent sizing, vent connections, slope, developed length, materials, fittings, and testing. Candidates should recognize the purpose of traps and vents and understand how improper installation can affect drainage performance.

Fuel-gas preparation may involve approved piping materials, sizing, appliance connections, shutoff valves, sediment traps, pressure testing, combustion air, regulators, equipment installation, and venting. Candidates should know when to consult the International Fuel Gas Code instead of the plumbing or mechanical code.

Mechanical and hydronic preparation may include boilers, circulating pumps, expansion tanks, air control, heat exchangers, valves, piping arrangements, controls, heat emitters, system filling, purging, and pressure or temperature protection.

Fire-sprinkler preparation may involve system types, design criteria, piping arrangements, sprinklers, valves, water supplies, residential systems, inspection, testing, and installation requirements. The package includes NFPA 13, NFPA 13D, and NFPA 13R to support study across different building and residential occupancy conditions.

Solar plumbing preparation may include solar collectors, storage tanks, heat exchangers, circulation systems, pumps, controls, piping, insulation, mounting coordination, freeze protection, stagnation protection, and system maintenance.

On-site wastewater study may address treatment-facility provisions, site conditions, disposal systems, permitting concepts, setbacks, installation, and operational requirements contained in the provided Arizona administrative-code material.

Passing the required examination does not automatically issue a contractor license. The Arizona Registrar of Contractors must review and approve the complete application before the business may operate under the CR-77 classification.

Open Book Test

The Arizona CR-77 trade examination is an open-book test using approved reference materials. Candidates may consult books permitted for the scheduled examination under PSI’s current rules concerning editions, highlighting, annotations, indexing, tabs, attachments, and book inspection.

An open-book format does not eliminate the need for technical knowledge. Candidates must identify the subject of each question, choose the appropriate reference, locate the controlling provision, interpret the language, and apply it to the plumbing condition presented.

All books are highlighted and Tabbed. Highlighting draws attention to important plumbing provisions, fuel-gas requirements, mechanical rules, sprinkler standards, formulas, tables, safety provisions, hydronic concepts, and Arizona wastewater information. Tabs help candidates move among major chapters and frequently researched topics more efficiently.

The references should be used throughout the course. Repeated navigation practice helps candidates learn where information is located and become familiar with indexes, definitions, tables, exceptions, diagrams, and permanent tab positions.

A question involving sanitary drainage, water distribution, venting, fixtures, or plumbing materials may require the International Plumbing Code. Fuel-gas questions may require the International Fuel Gas Code, while boilers and hydronic equipment may involve the International Mechanical Code.

Sprinkler questions may require NFPA 13, NFPA 13D, or NFPA 13R depending on the occupancy and system described. Excavation, ladders, tools, personal protective equipment, and construction-site safety may require OSHA.

All references remain subject to inspection. Loose pages, temporary tabs, removable notes, unauthorized attachments, and electronic materials are not permitted. Candidates should review the current testing instructions before bringing references to the examination center.

State Requirements

The CR-77 classification is an Arizona specialty dual license covering authorized plumbing work in residential and commercial settings, including qualifying solar plumbing systems.

The proposed qualifying party must demonstrate the experience, knowledge, and skills necessary to supervise or perform the work covered by the classification. Experience documentation may need to describe water piping, drainage, vents, gas piping, fixtures, equipment, hydronic systems, solar thermal work, service, repair, and project supervision.

The legal business entity applying for the license must be properly established and identified. The company name, ownership records, qualifying-party information, EIN documentation, contractor bond, and license application should remain consistent throughout the process.

Arizona contractor applicants must complete applicable background requirements and provide the identification, experience, examination, business, and disclosure information required for state review.

Because CR-77 includes solar authority, solar warranty documentation is required as part of the licensing process. This documentation is separate from the examination requirements.

A contractor license bond is required. As a dual classification, CR-77 is subject to the applicable residential and commercial bonding requirements based on the anticipated gross volume of work.

The residential portion of the license is also subject to Arizona’s residential financial-protection requirements. The applicant must satisfy the applicable Residential Contractors’ Recovery Fund obligation or authorized alternative.

After licensing, the contractor must remain within the CR-77 scope, maintain the required bond, renew the license, and keep business and qualifying-party information current. Changes involving ownership, entity structure, address, bond, or qualifying party may require additional filings.
