Abstract
A toilet includes a water storage tank, a bowl including a waste receiving basin that includes an upper rim and at least one toilet bowl aperture in a side wall of the waste receiving basin, a water supply plenum operable to receive water from the water tank and channel the water to the bowl, a primary drain operable to connect the basin and a sewer pipe, and a secondary drain fluidly operable to connect the toilet bowl aperture to the sewer pipe and operable to drain the water from the bowl. The secondary drain is separate from the primary drain and includes an auxiliary aperture fluidly connecting the secondary drain to the water supply plenum and operable to drain the water from the plenum. The toilet bowl aperture and the auxiliary aperture are operable to permit the water to bypass the primary drain when the primary drain is clogged.
