Pvc pipes are cheaper. They are easier to join. They last longer.
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).
You don't, you remove the plastic junk and replace the toxic plasatic with cast iron
Chlorinated - PVC normally used on hot water
Two ways. Caulked joints and ty-seal joints. Cut the cast iron behind the hub and use a Clamp-all to join it to PVC pipe. If this sounds too difficult, CALL a Plumber.Why do you want to replace your cast iron? That would be alot of work, only replace what you need to. Unless it is your sewer line then i would replace it all to the main. I agree with answer # 1.IN ADDITION:Back in the day, cast iron joints were sealed together with hot lead. Depending on the position of the cast iron pipe and the size of it. Either one can cut the cast iron piping and clamp PVC to it or you can melt the old lead out of the cast iron joints and place PVC piping inside and then "recork" (reseal) it with prattley putty to prevent it from leaking.CORRECT1- Older CI roof drains were installed by Caulking using oakum and then pouring molten lead2- Some older CI drain drains used a Durham system meaning the Cast Iron drains were SCREWED the pipe galvanized in most cases and then the galvanized was caulked into a cast iron bell.It is unprofessional and highly unskilled to replace a cast iron leader line with plastic for several reasons.Seems the non skilled always try to use some type of epoxy..You may want to contact a licensed master plumber who has had the required 10,000 hr apprenticeship training
The pipes are PVC electrical conduits.
These days PVC pipes are faster and easier to fit and in many ways more efficient than cast iron.

Because modern PVC and PEX pipes are much more efficient and easier to work with.
Well . . . there is cast iron, ductile iron, steel, copper, galvanized steel, PVC, ABS, concrete, fiberglas . . .
Less conductive I would say.
Definitely PVC
PVC is a compound.The pipes are not a compound but they are made from a compound.
Pipes are made of many different materiels, for different purposes, theres plastic PVC pipes, alluminium, steel, copper, brass, concrete, titanium, iron, ect.
Yes, but PVC creates problems
PVC stands for polyvinyl chloride, which is what PVC pipes are made of.
No PVC is acceptable, you can join the new PVC piping into the existing Cast Iron.
