A cast iron sewer drain can keep blocking for years without a tree root in sight. On this Melbourne job the cause was rust: heavy scale inside the 100mm pipe was snagging toilet paper and cutting the flow.
In brief
- Where: Melbourne
- Pipe: 100mm cast iron sewer drain
- Problem: heavy rust scale catching toilet paper and restricting flow
- Method: CCTV inspection, then a spinning chain flail with high pressure water jetting, then a final CCTV inspection
- Result: a smooth, restored inside surface
Why does an older home’s cast iron drain keep blocking?
In older Melbourne homes, repeat blockages often come from corrosion inside the pipe rather than from roots. Rust builds into a rough scale that catches paper and slows the water.
What did the job involve?
- Camera inspection: on this job a CCTV inspection showed the rust scale.
- Descaling: a spinning chain flail, working with high pressure water jetting, took the corrosion off the pipe wall.
- Camera again: a final CCTV inspection showed a smooth, restored inside surface.
