Duluth, MN - **Spring Curriculum**

**If you attended our classes in Spring 2025, please choose a 'Fall Curriculum' class. Otherwise, you may take either class.** Registration opens 30 minutes before we begin. This session includes 8 hours of code review as required by the State of Minnesota. These are state-approved courses. Every class is open for master, journeymen, and registered unlicensed/apprentice plumbers, water conditioners, and building officials.  This session covers Chapter 5, Chapter 7, and Chapter 9.  Learning outcomes include understanding the requirements and restrictions regarding water heaters (Chapter 5), how to correctly size and construct DWV systems, and the correct way to construct vertical and horizontal wet-vented systems (Chapter 9).  You may bring a code book with you, but materials needed for the day will be handed out in class.
