In and of itself, the sewer line for your home is no different than any other pipe. It may be a little larger and sturdier, but the principles are still the same: it still needs to carry wastewater out of your home, the same way that pipe under the sink does. The difficulty with sewer lines and other outdoor pipelines is that they’re most often buried beneath the ground.
This can be a big benefit because it protects them from damage quite well, but it also creates big problems when trouble does arise. The good news is that trained pipe technicians can usually repair problems such as leaks and clogs without having to dig. Trenchless technology has revolutionized pipe repair and allows us to repair leaks at a fraction of the time and cost.
