Illinois specific question

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.
