My home was built in 1917, and the waste water/sewer is the original. I have recently noticed some large rust nodules hanging from underneath the pipe. Some so bad, I am afraid to touch them for fear of putting my finger right through the pipe. Obviously, It should be replaced before the inevitable happens. I would like to tackle the job myself, but don't know much about codes. For instance: Can I replace with PVC of the same diameter? How do I transition from the cast iron to be left in place with the new PVC? And finally - is this going to be as nasty a job as I think it will be(speaking in terms of filth and stench not difficulty!)?
: Any ideas, info, and suggestions would be greatly appreciated!
