How does someone become a Commercial Plumbing Inspector?
ICC certifications are essential for building inspectors, plans examiners, and building officials. Certifications demonstrate that the inspector or plans examiner is properly trained in their field of expertise and can effectively apply the code to construction projects. Becoming a certified commercial plumbing inspector requires passing an International Code Council (ICC) certification exam. The entire process requires three basic steps:

2. How to study for the Commercial Plumbing Inspector (P2) exam
Knowing how to tackle answering questions from all of the required sections is a daunting task. Practicing answering commercial plumbing code questions is essential for an inspector or someone about to take an exam. In the field, an inspector should be able to answer general questions about fixtures, drains, vents, water heater installations and fuel supply installations. During an exam, test takers must be able to navigate the International Plumbing Code fast enough to answer all of the questions within the allowed time of 2:30 hours. Building Code Masters has several practice exams for plumbing inspectors to test their skills and learn the most essential questions and scenarios they will be presented with.

3. How to take the ICC Commercial Plumbing Inspector exam
When taking a plumbing code examination, it is essential to be able to navigate the code fast enough to find all of the answers. Most ICC examinations are open book and because of this, obscure and hard to memorize material will be included in all of the examinations i.e. large tables and mathematical formulas. The 2018 commercial plumbing inspector exam requires applicants to be able to answer the following questions in the allocated time:
Number of questions: 60
Time limit: 2:30 hours
This means that examinees will have roughly two and a half minutes per question. It may appear as a generous amount of time but some questions will be longer and more in depth than others which requires an inspector to be able to have section locations of the book memorized. Having chapter locations memorized and pacing oneself will lead to passing the exam. Practice exams from Building Code Masters prepare test takers for the time crunch and memorization of the most important sections of the code. Whether the exam be focused on building, mechanical, electrical, or plumbing, Building Code Masters has all of the study materials available to help test takers learn how to become better educated building inspectors, plans examiners, and building officials.
