Abstract
A flush valve apparatus for a toilet tank includes a float that provides a buoyancy force to a flush valve flapper. The float may be coupled to a chain connecting a lever and the flapper, or directly to the flapper. The float may be selected from a set of floats having a variety of sizes and shapes. Once a selected float is installed, the position of the float is fixed relative to the valve flapper, thus preventing change in the amount of water consumption per flush, which depends upon the buoyancy force on the flapper. For different standards, floats of different shapes and/or sizes may be selected such that the amount of water consumption per flush meets the standards.
