The company says the release of stored pressure from the system can "lift the tank lid and shatter the tank, posing impact or laceration hazards."
The system is used in more than 2.3 million toilets in the U.S. and is sold at Home Depot and Lowe's. It is also sold to toilet manufacturers that include American Standard, Crane, Eljer, Gerber, Kohler, Mansfield and St. Thomas.
If you think your toilet may have a Flushmate III Pressure-Assist Flushing System, turn off the water supply and stop using the unit. Contact Flushmate at 800-303-5123 or http://flushmate.com/recall/ to determine if your system is included in the recall. If it is, you can receive a free repair kit.
