First hour checklist
Stop adding water to the system. Keep people and pets away from contaminated water. Take photos for insurance if safe. If the backup is active, ask for emergency sewer or main-line help, not just routine sink drain service.
Ask the provider whether today’s visit is only to restore flow or also to diagnose the reason the backup happened.
When to treat a sewer problem as urgent
If sewage is coming up through a basement floor drain, shower, tub, or toilet, stop using water in the home and get help quickly. Do not run laundry, dishwashers, showers, or extra toilet flushes until the blockage is understood.
If one sink or toilet is slow, it may be a fixture or branch drain. If several fixtures are slow, the lowest drain backs up first, or sewage appears at a basement fixture, the main sewer line is more likely involved.
What to ask before approving expensive work
Ask whether the contractor has camera evidence, where the defect is located, what pipe material is involved, whether cleaning alone is enough, and whether the recommendation is repair, replacement, lining, pipe bursting, or excavation.
For a large quote, ask for a written scope showing access points, footage, depth, restoration, permits, warranty, and what would make the price change once work starts.

Common questions
Should I keep using water during a sewer backup?
No. Stop showers, laundry, dishwashers, and unnecessary flushing until the blockage is understood and flow is restored.
Does one slow drain mean the sewer line failed?
Not necessarily. One fixture can indicate a local clog; several affected fixtures or a backup at the lowest drain more strongly suggests a main building drain or sewer-lateral problem.
