Reply To: Water main break, two to the hospital and one just passed.

You think about it. A perfectly safe excavation could be a deathtrap with a main break like that. There's fragile stuff like AC, there are joints that lose integrity when you disturb or remove thrust blocks, there are many ways to fail a main under pressure. Too many joints in a short area and not enough blocks or megalug fittings, add the pipe and water weight if you undermine it.
