Would you replace the caste iron drainage pipe to PVC?

[Michael Stole]

It is an old house built in 1939. Some of the drainage pipe has been replaced to PVC, and majority (including the Stack) is still caste iron. And the cost is about 10 thousand dollars to replace all through the house.

I plan to live in the house for 2-3 years and resell it, so it is partly an investment.

@Michael Stole Will the house need any foundation work? If so, there is no telling what will happen to the pipes once you lift the foundation.

Otherwise you can have someone run a camera through the pipes to check for leaks and the overall integrity of the line. Would be a much cheaper alternative than gutting the whole system and fitting it with PVC.
