Map the symptom first
Write down whether the sound occurs only in one bathroom or throughout the property. Note any changing water level in the toilet and whether showers actually drain slowly. A fixture-specific pattern and a whole-house pattern point to different areas of the system. Avoid repeated test flushes if water is already rising.
Ask for a reasoned diagnostic sequence
The provider should explain whether branch drainage, venting, the main house drain, or the outside lateral needs checking first. An outside sewer camera survey alone may miss an indoor branch issue. Conversely, replacing a fixture will not resolve a downstream obstruction that affects several drains.
What justifies a repair recommendation
If the inspection reveals a structural defect, ask for the recording, measured distance, and explanation of its effect on flow. A crack, an offset, and a low spot are different problems. Cleaning, lining, spot repair, or replacement should follow that evidence rather than the noise alone.
Your next-step checklist
- Note which running fixture causes the gurgle
- Mention any toilet water-level change
- Separate vent and drain findings in the written report
