For used water to get carried away from your home and to a water treatment plant, you need to have a properly working underground plumbing system.
The section of pipe that is buried underground outside of your home contains the sewer line, which is the portion of your system that carries the used water to the treatment plant.
Not only is this section of your plumbing system vulnerable to clogs but, it is also vulnerable to the outside elements. Things like extreme temperatures, tree roots, and heavy rain can all cause damage to your sewer line.
It used to be, the only way to access your sewer line was to have a professional plumber come in with a backhoe and dig large trenches above the length of the pipe to find the damaged section. This exploration did the job as far as locating the problem and implementing a solution, but, it also caused a lot of additional damage.
With the digging method, after the sewer line repairs were completed, the homeowner was left with a destroyed lawn, patio, deck, and sometimes even driveway. All of this destruction required additional cost and time to repair and put back together.
