So the smoke test showed no leaks in the house, but a camera run through the pipe between the house and the septic tank showed that the 4' sections of cast iron are offset at just about every joint, from 70 years of settling and shifting. So that's where the smells in the yard are coming from, and probably the smells in the basement as well -- seeping through the masonry foundation.
So do I need to dig the whole thing up and re-lay new pipe? Or is there a way to line the existing 4" pipe?
Thanks.
