Julius Ciaccia, director of the City of Cleveland, holds a flushometer at Cleveland Browns Stadium, Wednesday, July 25, 2007, in Cleveland. 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 valves allowing water into the toilet when its flushed. But many of them became clogged with debris from iron deposits that flaked off the inside of old pipes in the Cleveland water system, leading to the problem. (AP Photo/Tony Dejak)
