Should you replace cast iron plumbing pipes with PVC?

    Yes, if the pipes are rusty and leaky I would suggest you replace them. How old are the pipes?

    I agree, replace as much as you can afford. Your problems will be solved for a very long period of time.

    Reminder... PVC carries it's own complications and limitations, so be careful what you decide.

    Where possible (and only to fix that which leaks, bridge in PVC runs but ensure the use of correct thickness of PVC

    I ended up being somewhat forced to do this as part of a much smaller plumbing project, so I think I didn't get the best deal I could have. Be sure to get some estimates and check references, as always.

    I have a 100 year old house. The cast iron finally cracked. My plumber is thinking he may put back the iron. I'm leaning toward the PVC as the house shifts in really dry/wet weather. What would you put back ????
