Sewer line inspections

[Bienes Raices]

Has anyone paid someone to come do one of these during their inspection period? My offer was accepted on a short sale where the seller and his friend apparently put in a new sewer line on their own (not sure what the reason was for doing that), so I thought it might be a good idea to have one done.

Also I read that some houses built in the 1950s have something called Orangeburg pipes which do not hold up well over time.
