PASSIVE BACKFLOW PREVENTION APPARATUS AND ASSOCIATED TOILET SYSTEM AND METHOD
A passive backflow prevention apparatus includes a tubular base that has a non-planar end defining an opening. The passive backflow prevention apparatus also includes a flap assembly that includes a non-planar flap. The passive backflow prevention apparatus further includes a hinge that pivotably couples together the tubular base and the flap assembly such that the flap assembly is pivotable from an open position, in which the non-planar flap of the flap assembly is disengaged with the non-planar end to enable a fluid, flowing in a first direction, through the opening, to a closed position, in which the non-planar flap of the flap assembly is engaged with the non-planar end to prevent a fluid, flowing in a second direction, through the opening.
