Several of us Texas Inspectors had this conversation awhile back and I did inquire with TSBPE. Their response is quite different from your interpretation. See the attached email. Have you validated this claim directly with TSBPE? Note that the person who responded to my email, Mr. Davis, was the Director of Enforcement at that time.
Will INACHI indemnify its members in Texas if the Texas Real Estate Commission, the home owner, or the Inspector’s client attempts to take any action against the Inspector as a result of performing a sewer scope without a Plumbers license?
