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.
