Do you know what type of pipe your sewer line is?

Depending on the age of your home, you could have several different types of pipes.


If your home was built 1946 to 1976 you could possibly have Orangeburg pipe. Orangeburg is a bituminized fiber pipe that is made from hot pitch and wood pulp. At the time Orangeburg pipe was ideal due to its light weight and cost effectiveness; however, Orangeburg is far from durable. Orangeburg is no longer used in sewer pipes due to its common issues and short lifespan.

Cast Iron

Cast iron pipes are the most common pipes found in older homes. If your home was constructed prior to 1975, you most likely have cast iron sewer lines. Cast iron is a pipe that can deteriorate and corrode over time which will eventually lead to failure and backups. While cast iron is one of the most durable pipes used in the sewer industry there is a life expectancy of 40-50 years. Cast iron is prone to rust and corrosion and will eventually require replacement.


If you live in a newer home built after 1970 you most likely will have plastic sewer lines also known as PVC (Polyvinyl Chloride). PVC is the most common and popular type of sewer lines installed in homes today. PVC is flexible, light weight, durable, and has a good resistant to chemicals.
