No $hit brother. I've seen water pressure push block walls over by a course or two inside a closed room when a pipe let go. Found one with the steel door swinging, barely, by it's closer arm, in the 5 foot high gusher that was rushing out of the doorway.
This was a 12" main coming into a 400,000 square foot office building in downtown DC. The flange by the incoming meter connection let go, and filled up a 8'x10' room damn near instantly. The pressure built (quickly) until it pushed the block wall over by about 10 inches, and then blew the steel door off of it's hinges. It flooded the lower two levels of the garage of the building.
Funny part of the story? The guy in charge of the garage had called me, and said that there was a "little" leak on the upper level.
LITTLE?
FUK ME!
