Modern homes have many “invisible” systems—such as buried cables and underground plumbing—that keep things running smoothly without drawing attention to themselves. The flip side of this convenience, however, is that when something breaks down, the problem can go on for a while before becoming obvious.
This is especially true when it comes to your home’s sewer line, the pipe system that discreetly moves all wastewater from your toilets and drains into the main city sewer (unless, of course, you have a septic system). It’s great that we don’t have to think about where all that waste goes—until something goes wrong.
