The short answer
Record which drain blocks, how often and how long flow stays normal after clearing. Include the date and method of earlier work if known. A repeat at one fixture is a different pattern from a whole-home backup.
Clearing, cleaning or looking inside?
Compare what each tool does. Select a card to highlight the question to ask; the method descriptions stay visible.
Snaking / cabling
Acts mechanically on an obstruction.
Ask which access point is suitable and whether flow was fully restored.
Hydro jetting
Uses water to clean suitable pipework.
Ask how pipe condition and the obstruction affect method selection.
Camera inspection
Records the visible condition of a line.
Ask for the location and recording behind a recurring-blockage recommendation.
Ask which access point is suitable and whether flow was fully restored.
Educational comparison. A professional chooses a method after assessing access, obstruction and pipe condition.
Ask what was actually removed
A provider should explain whether it found a local obstruction, buildup or evidence farther along the connection. Ask what remains uncertain. Do not assume roots or pipe failure merely because the house is old.
Use inspection when it can answer a question
A camera may help document the line after access and visibility are suitable. Ask for the location of any finding, what the view showed and how it supports the recommendation. Cleaning and structural repair are separate decisions.
Make prevention specific
Keep grease and wipes out of the system, use suitable strainers and follow the provider’s advice for the finding. Prevention cannot fix an existing structural defect; an inspection cannot substitute for removing a blockage.
The snake did not work, or flow returned briefly
Tell the provider whether the cable met resistance, whether any material was retrieved and how long drainage improved. A tool can pass through a restriction without fully clearing it. Recurrence can also involve material left behind, roots or a pipe defect. Do not conclude that hydro jetting or replacement is automatically necessary; request an explanation tied to the line condition.
