Stage 1 Roots have entered the sewer system, causing partial stoppage. This can usually be cleared by water jetting. However this would only give temporary relief. Stage 2 Roots have clogged the sewer system causing serious damage. This can be fixed permanently by replacing a section of your sewer pipe, or water jetting to cut out the roots and pipe-lining to repair the break. Stage 3 Roots have caused the sewer to collapse or have damaged the pipe beyond repair. This usually causes a catastrophic blockage. (One that cannot be cleared). Excavation and repair will be required. At this stage unfortunately relining is no longer an option. |
