Abstract
A toilet fixture includes a bowl, a primary drain fluidly connects said basin and said sewer drainage pipe, and a supply water plenum. The fixture further includes a secondary drain fluidly connecting said supply water plenum to said sewer drainage pipe. The secondary drain is separate from said primary drain and includes inlet means that are disposed within said supply water plenum and include at least one unshielded secondary drain hole in a lower half of the plenum. The secondary drain further includes a second drain channel. The secondary drain further includes a second drain outlet that is in fluid communication with said second drain channel, whereby said inlet means permits rising waste water to flow from said supply water plenum into said second drain channel and out of said second drain outlet to said sewer drainage pipe separately from the primary drain.
