Abstract
A gravity flush toilet system is provides that includes a toilet bowl assembly having a toilet bowl and a tank, wherein the bowl includes a trapway extending from the bottom of the toilet bowl to a sewage line. The toilet system is capable of operating at multiple flush volumes without loss of siphonic function or significant change in the surface area of the water in the bowl. The multiple flush volumes allow the user to select appropriate water usages for the required waste removal without diminishing the performance of the toilet, resulting in significant water savings.
