This is one of the toughest repairs that we've ever done. The sewer pipe was broken in two places at the foundation and all of the water was draining into the sump pit under the floor in the basement, plus the pipe had a major 30' long sag out to the sidewalk.
The original pipe was installed too low when the house was built to have the proper downhill pitch needed for drainage
What made this repair so difficult is the depth at the house, @9' deep under the porch, a big tree, no room to effectively dig between the houses, the pipe is under the sidewalk right next to the length of the foundation for 20', and the gas line is right on top of it.
After much discussion we decided to use the pneumatic mole to bore a new line, abandoning the old one. It worked GREAT!. Not only did we not have to try a dangerous excavation, but it actually corrected the pitch out to the street. We also installed two way 4" cleanouts for future access.
