We're looking into the possibility of replacing our internal cast iron soil pipe with a plastic one (in the same location). It's not clear to me how easy it will be to gain the access necessary to replace the whole thing which I suspect may make it an expensive job.
If this is the case, is it possible (and practical) to look at a partial replacement of everything above a certain level of cast iron pipe? (with the cast iron portion supported at the wall)
