While researching sewer scope training, I came across this web site imt.digitalchalk.com.
This is their statement:
This is the only online course that allows you to become an InterNACHI Certified Sewer Scope Inspector and/or Sewer Scope Certified.
And they state that James Krumm is the instructor
I understand it is a hands on course at the House of Horrors in Boulder taught by James Krumm. I think it is about $500.00.
I don’t know what the link is you posted
I see Jim teaching it at the House of Horrors in Boulder from time to time. They have about 60 feet of ABS sewer pipe installed for practicing sewer scope. Jim teaches various things for InterNACHI and he’s done some videos with them.
He’s had 8-10 guys in the class when I’ve been there.
