Grease can coat a drain wall or smear across a camera lens. The crew may see a restriction without seeing the condition of the pipe behind it. That difference matters if the footage is being used to recommend repairs.
Ask which pipe wall was visible
Request the clip and note where the view became unclear. Ask whether the lens was cleaned and whether the camera could see beyond the buildup. Keep the access point and direction with the video.
Decide whether another pass would help
If the line is suitable for cleaning, a follow-up pass can show features the first video obscured. Ask what a second inspection would confirm before comparing a cleaning quote with a structural repair.
