A waterfall of thousands of gallons of liquid overflowed a holding tank and poured into Cleveland Browns Stadium because of a massive plumbing backup during a recent concert, not because of a water pipe break as initially reported. A flushometer is located in each of the 1,500 toilets and urinals inside the stadium. They act as a valve allowing water into the toilet when its flushed. The flushometer was the problem for the plumbing backup. (AP Photo/Tony Dejak)
