Describe the wastewater connection before requesting drain work
Ask the owner whether the property connects to central sewer or an onsite system. Locate existing records and describe which fixtures back up; do not assume clearing an indoor branch resolves a downstream system fault.

For this assessment: practical questions and records
Record the affected fixtures and whether another discharge triggers the backup. Stop using overflowing fixtures; avoid chemical drain products. Ask whether the initial visit investigates the indoor branch, private sewer connection or onsite-system equipment, and what evidence justifies the next step.

State Callahan, the full address and the fixture or equipment involved. Describe whether water is still escaping, whether one or several fixtures are affected and any safe isolation already performed. If you are unsure of the source, say so rather than repeating an assumed diagnosis.
