If there is any part of your plumbing system that’s most important, it may very well be the sewer line—the pipe that removes wastewater from your property and moves it into the civic sewer system cleanly away from your home. Sewer lines are usually buried underground, in your back or front yard, safe from damage that can come from inclement weather and other types of wear and tear.
Unfortunately, this doesn’t mean that your sewer line is immune to all problems. Your landscaping like trees and shrubs can grow roots that infiltrate the line, for instance. A shift in the soil could cause instability and pipe breakage, too.
