Repair pipe under slab Arrived to home to remove section of slab and replace 2” drainage. We demo slab, removed old cast iron pipe which was very backpitched and also almost completely full towards end of run. Cut out line, used flex shaft to clear out remaining we did not touch. . Line is clear, we replaced with solid core pvc and pitched accordingly. Filled sink multiple times and tested for leaks, there are none at this time. MyGuy is not responsible for replacing concrete that was removed to perform work. I wrapped caution tape around exposed rebar to avoid tripping. MyGuy is not responsible for any slips falls or injuries if someone is to do so around exposed hole.
