Radon and sewer

I just had a enter forwarded to me from a different inspector stating that you are not supposed to test for radon for 12. Hours after performing a sewer scope? Is this correct? If you are scoping from an exterior clean out this should have no barring. If you are removing a toilet I see some potential issues.

Any input (facts) would be great

He’s wrong.

Crazy talk

Agree with what he said… :slight_smile:
