We can say it is a good thing to find the trouble at the bottom which would have reared its ugly head someday especially if we had tried to install a cosmetic fix for the existing slab.
Excavation of the sewer pipes was supposed to allow us to connect the new plumbing layout to the existing sewer lines. Unfortunately the pipes were in sad shape under the lower end of their run. Rusted, cracked, crumbling away and scary to say the least, knowing that I had been using them just a few weeks before and most of the summer.
We needed a permit anyway to start rebuilding, so it was time to go to the city and see what they would need for a general permit.
