Geyser
Nothing like a good old shower at work. That water was shooting up about twice as high as the utility pole in the forground stands. The machine cab was soaked, there was gravel all over on top of the machine, and it was just 'one of those things'. No one knew there was a blowoff valve on the main, let along sticking up. We were following the line in order to find the end that should have been tied into the rest of the system, but wasn't. Infact, the contractor had paved right over the unfinished work, leaving us a real mess to figure out.
