I am wondering if I should have a camera scope done on my sewage line. I had the line unclogged yesterday. They had to go out 150 feet (last time was 7 years ago and it was 126 feet). The owner of the plumbing place suggested the camera scope. I have talked to several people since then and have been advised not to do it now. If something happens within a year, then it should be done. Is that good advice?
