Claim 8:
9. A toilet, comprising:
an inlet structure comprising an inlet for receiving water, a horizontal section, and an elbow fluidly connecting the inlet to the horizontal section, the elbow comprising a breaking radius and having a circular cross sectional shape;
a bowl structure comprising a toilet bowl having a rim and a sump, a split located downstream of the horizontal section and having a first passage and a second passage, the split dividing water flowing from the horizontal section into the first passage and the second passage, a shelf located below the rim and fluidly connected to the first passage;
a plurality of side channels connected to the second passage, the plurality of side channels including a first side channel and a second side channel, wherein the first side channel extends from the split downwardly around a first side of the toilet bowl, wherein the second side channel of the plurality of side channels extends from the split downwardly around a second side of the toilet bowl opposite the first side, and a diverter that redirects the water from the side channel to an inlet opening into the sump; and
an outlet structure comprising a trapway that is fluidly connected to the sump and has an outlet,
wherein together the rim and the shelf form an inset channel that extends along a perimeter of the toilet bowl in a single flow direction and is open to a waste receiving surface of the toilet bowl, and wherein a thickness of the rim increases so that a lower surface of the rim slopes downwardly toward the shelf so that a height of the inset channel, between the rim and the shelf, decreases in the single flow direction to reduce fluid losses in the single flow direction.
