What Is the ICC P2 Examination?

The P2 examination is the ICC Commercial Plumbing Inspector national certification exam. It evaluates a candidate’s ability to inspect commercial plumbing and related fuel-gas systems for compliance with applicable code requirements.

Current official examination information lists:

• 60 examination questions
• Two-hour-and-30-minute time limit
• Open-book format for the current package
• Scaled passing score of 75

A scaled score of 75 is not the same as answering exactly 75% of the questions correctly. ICC uses scaled scoring to maintain a consistent passing standard across different versions of certification exams.

Candidates should verify the selected code year, testing method, approved references, and exam-day rules in the current ICC Exam Catalog before registering.

P2 Exam References

The current 2021 P2 package identifies the following references:

• International Plumbing Code, 2021 Edition
• International Fuel Gas Code, 2021 Edition
• ICC A117.1-2017 Accessible and Usable Buildings and Facilities

The International Plumbing Code supports preparation involving fixtures, water supply, water heaters, sanitary drainage, vents, traps, interceptors, special waste, storm drainage, materials, joints, testing, and commercial plumbing installation requirements.

The International Fuel Gas Code supports preparation involving gas piping, pipe sizing, appliance installation, combustion air, chimneys, vents, pressure testing, regulators, and fuel-gas safety.

ICC A117.1-2017 supports preparation involving accessible toilet rooms, bathing facilities, fixture heights, clear floor spaces, reach ranges, grab bars, turning spaces, and other accessible plumbing features.

How the Three References Work Together

• Use the International Plumbing Code for most commercial plumbing-system requirements.
• Use the International Fuel Gas Code for gas-fired water heaters, gas piping, combustion air, appliance connections, chimneys, and vents.
• Use ICC A117.1-2017 for accessible plumbing fixtures, toilet rooms, bathing rooms, clearances, heights, and approach spaces.

Some questions may require more than one reference. An accessible toilet room with a gas-fired water heater, for example, can involve plumbing, accessibility, and fuel-gas requirements.
