"In a chemical plant where I worked, the soda products unit was undergoing major production improvements, including bringing in more water and electricity. The plumbers made the final connection to the 3-inch galvanized water pipe they had stubbed in earlier, and turned on the water. Suddenly, everything in the plant went silent. Water was spewing out of every starter fed from the wiring gutter the 3-inch conduit was connected to."
