Is it within the scope of a licensed home inspector to open the cleanouts of the plumbing system as part of the inspection. I was under the impression that this could only be done by a licensed plumber.
If you read SOP every system says Inspect other than Plumbing.
You have no reason to open a clean-out unless roding it or doing a video scan.
Plumbers are Licensed in Illinois.
Answer is NO.
Ditto to Bill.
