Main Line Clog
A main line clog is a blockage in the pipe that carries all of the house drainage to the city sewer or septic tank. The pipe itself is intact; something is stopping the flow.

Common signs
- Several drains backing up at the same time
- Water rising in the tub or shower when a toilet flushes

What the provider typically checks
A plumber clears the line from a cleanout with a large sewer cable, often followed by a camera inspection to see what caused the blockage and whether the pipe is damaged.
Before you call
Stop running water anywhere in the house, including the washer and dishwasher, until the line is clear.

Questions
How is this different from sewer line repair?
This page is about clearing a blockage. If a camera shows broken, collapsed or offset pipe, that is sewer line repair.
Who is responsible for the sewer line?
In many cities the homeowner is responsible from the house to the main or property line. Rules differ by city, so check with the local utility.
Who decides what the work will cost?
The independent provider sets the scope and the charges after looking at the problem. Confirm all details directly with the provider on the call.
