Pride Plumbing came out and provided a cost estimate to perform the following work: 1) cut out and remove cast iron and ABS piping from the main drain stack underneath the home in the crawl space; 2) install new PVC piping and fittings and connect onto the existing cast iron drain piping going out underneath the foundation; 3) cap any drain piping that is no longer being used; and 4) test for leaks and proper drainage.
