  • Patent number: 7203976
    Abstract: A floor level pumping system, that is non-disruptive to the existing flooring, including a conventional rear outlet toilet, a floor level tank for receiving waste and fluid from the outlet of the toilet including a tank chamber containing a designated area with a sensing system which activates a discharge pump when the level or quantity of the waste and fluid within the tank chamber reaches a predetermined level, wherein the chamber further includes one or more baffles extending upward from a floor of the tank chamber, which baffles at least partially segregate the designated area from the remaining area of the tank chamber, wherein at least one of said baffles contains a curved surface, and a discharge pump for pumping waste from the floor level tank out through a discharge pipe, wherein the discharge pump is secured to the floor level tank.

  • Patent number: 6495040
    Abstract: A filtering system for filtering effluent in a septic tank including an outer secondary filter secured within a pipe fitting, wherein the outer secondary filter includes a central opening passing therethrough; an inner primary filter, wherein the inner primary filter is slidingly engaged within the central opening in the outer secondary filter; and a filtering connection element, secured between the outer secondary filter and an inner surface of the pipe fitting, wherein the filtering connection element filters effluent passing upward through the filter pipe fitting and wherein upon removal of the inner primary filter, the outer secondary filter filters the effluent entering the pipe fitting before discharge. Either or both of the outer secondary filter or the inner primary filter may be formed with a biocide to retard the growth of biological material on their surfaces.
