Summary:A toilet has a trapway extending between a bowl opening and an outlet opening. The trapway defines a curved, preferably uniform circular cross-section water dam region above the bowl opening, a down leg, and a straight out leg between the down leg and the outlet opening. The down leg has a rearward slope where is located a horizontal baffle. The inclined down leg and horizontal baffle work in concert to prevent the back flow of air to a region above the dam as well as to facilitate rapid entrainment and evacuation of air below the dam.
