Sewer Scope Inspector Training

Become a Sewer Scope Inspector in this one-day, hands-on training held at the InterNACHI® House of Horrors®. Certified Master Inspector® and InterNACHI® CPI Jim Krumm will be the instructor. You'll learn how to perform sewer scope inspections, identify and describe pipes and defects observed during the inspection, and add this ancillary inspection to your business in the most profitable way. You'll be using a few different types of sewer scopes and cameras. And you'll be inspecting various types of pipe and defects purposely installed in the pipe system at the House of Horrors®.

This training is being held at the InterNACHI® Colorado location inside InterNACHI® Headquarters located in Boulder. Students will be able to tour the House of Horrors®, a full-size house with a thousand defects built in.
