The difference between the methods
Rodding uses linked flexible rods and attachments to reach and move a local obstruction. Jetting uses pressurised water through a hose and nozzle to move a blockage and clean deposits from within a suitable drainage run.
Each method has limits. The pipe condition, access point and type of material involved should inform the method chosen.
- Rodding: simple, accessible obstructions
- Jetting: deposits such as grease, silt and debris where the pipe is suitable
- Camera inspection: recurring faults or suspected damage
- Repair: verified pipe defects rather than clearance alone
Questions to ask about clearance
A provider should explain why a method is being proposed, what access will be used and what outcome it can reasonably achieve. For a repeat blockage, ask whether a camera inspection is appropriate after clearance to check for an underlying cause.
- Is the pipe condition known?
- What caused the blockage, if known?
- Could the work reveal a separate repair need?
- Will the clearance method be adjusted if a defect is suspected?
Reducing repeat problems
Clearing a blockage restores flow, but a repeat issue can signal residual deposits or a fault in the drainage run. Good information about symptoms, previous clearances and access conditions supports a more useful assessment.
Frequently asked questions
Which method is better?
Neither is automatically best. The appropriate method depends on the blockage, access and pipe condition.
Can jetting be used on damaged pipes?
Pipe condition should be considered before clearance. If damage is suspected, a survey or cautious assessment may be appropriate.
What if a blockage keeps returning?
A recurring blockage can justify camera inspection to identify the accessible condition of the pipe and possible underlying causes.
