Atlas Plumbing arranged for a subcontractor, who does tunneling, to came out and dig an 18 foot tunnel under the patio and under the house. Other plumbing companies wanted to tear up the patio. Atlas replaced the broken line and then trenched out to the city sewer and laid a new pipe. After the inspector approved the work, they did an excellent job of packing the dirt back into the tunnel and covered the trench.
