that’s a BIG line
I’ve seen the aftermath from a 54” that blew apart at a Fitting after a crew dug the Blocking (after they were warned to be careful to not move or remove it) that was a concrete block as big as a midsize car from behind that Fitting. Filled a hole 40’ deep and about 150’ x 200’ before We could get the Pumps turned Off that were about 2 miles down the road.
