What the service should include
The survey should identify the run, access point, direction and distance. A dirty or water-filled pipe can obscure defects, so cleaning may be needed first.
- Confirm the affected system and access
- Assess hazards and previous treatments
- Explain the proposed method
- Check the result before leaving
Questions, evidence and outcome
Expect usable footage and a report that separates observed facts from repair recommendations, with defect positions and limitations stated.
- Will the pipe be cleaned first if needed?
- Are distance, defects and access points recorded?
- Will you receive video, images and a written report?
Step-by-step approach
- 1
Describe every symptom

Disclose products and previous work
- 3
Agree scope and price basis
- 4
Ask how the result will be verified
- 5
Keep footage, reports and repair recommendations
Important safety point
Tell the engineer about every chemical or home treatment already used. Hidden corrosive liquid can put people at risk when a pipe or trap is opened.
