It looks like we have to replace one of the drain lines running under our house - going from the kitchen probably to the laundry area. It will involve jack hammering a hole in our slab floor in two locations.
I'm trying to think of good questions to ask potential plumbers. I think there are issues I have to consider such as
* inspection of the radiant heat system after the work is done
* uneven settling or cracking as the replacement cement cures.
* will we have to re-open a hole if other lines corrode.
I was wondering if you have done this and what other questions or issues you might have run into.
