A slow drain: useful observations
Note which fixtures are affected and whether the problem is recurring. Multiple affected fixtures can help frame the service conversation; observations alone do not establish the cause.
Know what to share.
Preparing for a camera inspection
Share earlier inspection information and the location of any known access point. An inspection shows visible conditions within the accessible line; discuss the findings and limitations.
Planning a home repair
Describe the affected area, desired result, approximate dimensions and access. Confirm scope, materials and scheduling with the business.
