Joe, you must be crazy. I have personally overseen the installation of 10s of 1000s of l.f. of c.i. DWV piping and I consider it to be FAR more reliable than anything else.

Sorry to disagree. I have yet to see a deteriorated PVC drain or vent. Article that I've read predict a 100 year life for PVC piping.

P.s. I don't know what "i.f." means.

Seems to me it's only a matter of time before the 'seeps' turn into what I saw yesterday... A few lines cracked open and possibly some small additional leaks around the corner. Can't say for sure, didn't bring my scuba gear!

How do you define "best"?

Cast iron drain pipes were present and this typically indicates an older system. Cast iron is subject to deterioration from the inside out. These types of pipe can clog or fail at any time. Signs of deterioration, corrosion and seepage were present. A licensed and competent plumbing contractor can service and correct as needed. Budget for unexpected repairs or replacement in any building with older original plumbing.
