3. How to take the ICC Residential 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 residential plumbing inspector exam requires applicants to be able to answer the following questions in the allocated time:


  • Number of questions: 60

  • Time limit: 2 hours


This means that examinees will have roughly two 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.
