<p>HIGH PERFORMANCE TOILET CAPABLE OF OPERATION AT REDUCED FLUSH In a first aspect there is disclosed a siphonic, gravity-powered toilet having a toilet bowl assembly (10). The toilet bowl assembly comprises a toilet bowl assembly inlet (36) in fluid communication with a source of fluid and a toilet bowl having a rim (14) around an upper perimeter thereof and defining a rim channel (16). The rim has an inlet port (28) and at least one rim outlet port (18), wherein the rim channel inlet port is in fluid communication with the toilet bowl assembly inlet. The toilet bowl assembly further includes a bowl outlet (30) in fluid communication with a sewage outlet (34), and a direct-fed jet (28) in fluid communication with the toilet bowl assembly inlet for receiving fluid from the source of fluid and the bowl outlet for discharging fluid. The toilet is capable of operating at a flush volume of no greater than about 6.0 liters and the water exiting the at least one rim outlet port is pressurized such that an integral of a curve representing rim pressure plotted against time during a flush cycle exceeds 3 in.
