Why were cast iron pipes replaced by PVC pipes?
Pvc pipes are cheaper. They are easier to join. They last longer.
Which is better and will last longer when replacing main sewer drain lines - cast iron pipes or 4 PVC pipes if the plumber gave you a 3-year warranty on the cast iron and a 1-year on the PVC?
I can't imagine the plumber only giving 1 year on the PVC. Cast iron is rough on the inside and those rought spots can snag paper, lint, etc, eventually leading to blockage. PVC should last much longer and be less susceptible to blockages from material getting caught on the inside wall of the pipes. Also, PVC doesn't rust, while cast iron will. All-in-all, I'd have to vote for the PVC (make sure that it is at least Schedule 40 PVC).
