What Is the Best Material for Sewer Pipe for Rental Homes?

[Jay Truong]

Hi,

I am buying a triplex in Tempe, AZ and I am thinking of replacing the entire sewer pipe as the triplex is about 50 year old. However, I am not sure what the material (PVC, cast iron, etc.) to use as tenants might abuse the system more than owners. Please suggest me the best material to use and the approximated price.

Thanks.
