Key takeaways
- Clay pipe has many joints where roots enter
- Cast iron corrodes and scales over decades
- Orangeburg is a fiber pipe that softens and deforms
- PVC is durable but can be damaged or misaligned
Clay (vitrified clay)
Common in older homes. Strong in itself but laid in short sections with many joints. Roots love the joints, and ground movement can crack or offset them.
Cast iron
Strong and long-lasting but prone to corrosion from the inside. Scale narrows the pipe and eventually the wall thins or cracks.
Orangeburg
A bituminous fiber pipe used mid-century. It can soften, flatten and delaminate. Many are at the end of life. Some can be lined if the shape is intact.
PVC and ABS
Modern plastics resist corrosion and roots. Problems usually come from poor bedding, crushing or bad glued joints.
Which repair fits
Lining suits many of these when the pipe is still continuous. Bursting or replacement fits collapsed or badly deformed pipe. A camera shows the answer.
