The Flushmate ST100500 Cartridge Wrench (#129647) or Flushmate ST100100 2-in-1 Wrench (#129646) are not required, but it makes removal and replacement of the Flushmate cartridge easier.

How the cartridge works: When you press the flush handle on the toilet, the linkage rod depresses the cartridge. When the cartridge is depressed, it starts the flush cycle by letting the pressurized water out of the vessel and into the toilet bowl.
