The decision in practical terms
Choose according to the blockage material, location and access. A product or tool is good value only when it fits the job and can be used safely.
- Distance to obstruction
- Stopper and waste access
- Ability to retrieve material
- Fixture and pipe compatibility
Compare the whole purchase
Look beyond headline strength, cable length or pressure. Include protective equipment, compatible accessories, number of treatments, cleaning, storage and the cost of an unsuitable attempt.
- Clear intended application
- Material and fixture compatibility
- Controllable use
- Support, instructions and replacement parts
