How Long Do Sewer Lines Last? A Guide by Pipe Material
Your home's age is the first clue
The year a house was built usually tells you what material went in the ground, unless the line has been replaced since.
Clay tile
Clay itself resists corrosion, but its many joints are vulnerable to roots and shifting soil.
Cast iron
Common in older homes and under slabs. It corrodes from the inside and can crack along the bottom over time.
Orangeburg
Fiber pipe used mid-century that tends to deform and collapse. It is generally a replacement candidate when found.
PVC
Modern plastic pipe with glued joints that resist roots. Lifespan depends heavily on proper bedding and slope.
Age is not a diagnosis
Conditions vary widely, so a camera inspection is the only way to know the state of a specific line.
