NO, unless the inspector is also a licensed plumber. TREC’s Standards of Practice (§535.231) require an inspector to operate plumbing fixtures, test for drain performance, and to report deficiencies in water supply pipes and waste pipes. An inspector can inspect the condition of an accessible pipe by visually inspecting the exterior of the pipe, by feeling the exterior with his or her hand, or by using a mirror or a camera that does not enter the sewer pipe. A TREC inspector is specifically exempt from inspecting for defects or deficiencies that are otherwise buried, hidden, latent, or concealed and should not inspect the interior of pipes using specialized invasive techniques or equipment such as a sewer scope. According to the Texas State Board of Plumbing Examiners, a sewer scope inspection must be performed by a licensed plumber, and an inspector who performs a sewer scope inspection could be subject to disciplinary action by TREC or the Board of Plumbing Examiners.
