Hi everyone,

We own a rental property, built in 1950 so some of the systems are
nearing the end of their life expectancy. For example, the waste
stack in the basement is seeping a little bit, so it needs to be
replaced. My question is, what should it be replaced with, cast iron
or plastic, and what should I expect to pay for this? How big of a
hole needs to be cut into the basement floor?

Thanks,
Fish
