Houses built before the 1970's are likely to have cast iron drain piping. Other uncommon piping types used were clay, wood, and fiber conduit (Orangeburg). While cast iron is said to last anywhere from 50-100 years, it's always best to have a sewer scope inspection performed during the sale of any house built prior to the 1970's. This can determine the condition of the drainage system, while also checking for issues commonly found in older, cast iron piping. Such issues can be corrosion within the interior of the pipe, which can deteriorate the piping and allow for tree root intrusion.
