Drain/sewer and vent pipes in newer homes are either ABS (black) or PVC (white) plastic cell core pipes. The sewer line that runs from the home to the street or septic can very to alot of different kinds of pipe and some are good and some fail alot. If you live in a older home or have a older commercial building chances are you can have either bell cast iron, copper or galvanized and in some cases clay unless it has been upgraded. Galvanized in most civilized codes can NOT be used under ground (unless coated) Sewer piping under ground can be Type K copper, Service weight CI, HXCI, NH CI, clay pipe , Class 22 CI
