If nothing inside the home was altered you should not be getting a smell. Personally I'm confused as to why the repair person would have left the original line there and ran another one through a new hole. I would have pulled the old line up, ran the new line (in PVC) and used the same hole in the septic tank instead of creating a new one. Did he seal up the hole in the tank from the old line?
Of course, some repairs are easier and quicker to handle than others. Some are a major hassle—particularly those that involve working on pipes that are hidden behind walls or under floors or are otherwise difficult to access. This doesn’t mean you can’t do them yourself, it just means you may need a little more instruction, a few more tools, and a load of patience.
