It may be, but I'll cross that road when we get there. If we have to do an excavation project, I'll wait until I have a need to dig up the front yard. The pipe was solid, the metal shiny, and the bottom was thick. Looking into it, there was very little scale in it, certainly not the kind like I've seen elsewhere, where a good portion of the diameter is filled in. The full horizontal run but the couple feet going to the underground run was replaced. I didn't do the verticals because that too would require demolition in the walls, and I just don't have a need, they looked fine, none of the same telltale issues seen in the horizontal pipe either. When the time comes that the opportunity exists, rest assured the verticals, as well as the copper water service will be replaced. I have zero complaints on the drains in the home, so even if roots are present, they aren't causing an issue currently, knock on wood.

Pipe has a lifespan, especially old cast iron drains and vents which are all approaching 100 years old. They get pinholes and you will see little rust spots all up and down them.
