Before calling
What information to prepare

Which fixtures are backing up.
Whether water rises in tubs or showers after flushing.
Whether an outdoor cleanout is overflowing.
How long the symptoms have been happening.
Decision support
How to recognize a likely main-line problem
Main sewer symptoms are usually higher risk when several fixtures react together or wastewater appears at a low drain or cleanout.
Treat toilet-and-tub backup, floor drain overflow, and outdoor cleanout overflow as stronger main-line warning signs.
Stop water use when more than one fixture reacts because every extra gallon can push wastewater into lower openings.
Mention heavy rain, recurring backups, roots, or prior cleanings because those details can change the next diagnostic step.
Ask whether the provider is clearing a line, inspecting the cause, or recommending repair planning.
