Troubleshooting Common Complications
When an underground outdoor drainage pipe is clogged, identifying the issue is the first step to resolving it. Use a plumber's snake to detect blockages. If the snake encounters resistance, there's likely a blockage.
Assess the Material: Determine the type of debris causing the blockage. Is it organic, like leaves or roots, or inorganic, like plastic?
| Type of Complication | Solution |
|---|---|
| Organic Blockage | Use a high-pressure water jetter to clear leaves, roots, and debris. |
| Inorganic Blockage | If the blockage is solid and cannot be cleared with jetting, a pipe inspection camera might be necessary to locate the blockage for manual removal. |
Sometimes, pipelines collapse or are invaded by tree roots. Listen for a hissing sound when using a plumber's snake or jetter, indicating a possible pipe break.
- Collapsed Pipes: If significant force from a snake or jet doesn't clear the clog, a pipeline may be collapsed. Consult a professional immediately.
- Root Intrusion: Clear minor root growth with root-cutting nozzles on a hydro-jetter. For extensive growth, professional services may be required for repair or pipe replacement.
For persistent issues, it might be worth investing in a CCTV drain survey to get a clear image of the internal pipe condition. This helps plan the most effective course of action.
Remember, safety first. Always wear protective gear and take precautions to avoid damage to the pipe or injury to yourself. If the complication seems beyond your expertise, don't hesitate to contact a professional plumber.
