They've sleeved everything from the house to the main in PVC, and it needs to cure. So it'll be another "drain in the yard" scenario, except this time it's "drain in the hole in the street - which empties into the main. Which is ok, kinda.
Tomorrow they'll come back and connect and glue everything and fill it all with a bladder (ironic), which is like a big baloon that will hold everything in place while it dries/cures. Thus the no water flow. At all.
But Wednesday morning they'll pull the plug and it'll be wide open. The guy will run the camera down the length of the whole system and see for himself that it's wide open and ready for another hundred years.
We're still not holding our breath, but wondering just what else could go wrong? What's left?!
