When you flush a toilet, take a shower, or rinse your dishes in the sink, you abstractly know that all of the waste somehow makes its way to the city sewer system. But you don’t think about your home’s sewer line that makes this happen. And what you might not know is that this is a single pipe that carries everything out of your home. So when there is an issue with your sewer line, all that dirty water and waste can and will begin to back up into your home.
