Following the explosions of at least 304 toilets, the manufacturer of a toilet flushing system has ordered the recall of more than 2.3 million units.

Flushmate, a division of Sloan Valve Company, manufactured about 2,330,600 Flushmate III devices between October 1997 and February 2008.

In recent years, hundreds of people have called the company to report the devices burst, releasing enough stored pressure to lift the lids and shatter the tanks of toilet.
