A system for distributing fluid from a single fluid source into multiple receptacles, wherein: a fluid distribution manifold (24, 142) comprising a solid body having a fluid inlet in communication with the single fluid source at a central location leading to an inner chamber (174, 176), the fluid distribution manifold (24, 142) having a plurality of evenly spaced internal passages extending outward from inner apertures opening to the inner chamber to multiple fluid outlets distributed evenly around an outer periphery of the body, wherein the solid body of the fluid distribution manifold (24, 142) has a cylindrical shape with the internal passages and fluid outlets extending radially outward from the inner chamber, the outlet conduits initially projecting radially outward from the body and bending 90° downward; a plurality of outlet conduits fluidly connected to the fluid outlets; a plurality of receptacles each of which has an outlet conduit connected thereto, wherein fluid provided to the fluid inlet of the fluid distribution manifold (24, 142) is distributed evenly through the internal passages, fluid outlets, and outlet conduits into the receptacles; a gas vent in each receptacle; a vent manifold (50, 140) disposed adjacent the fluid distribution manifold (24, 142), the vent manifold (50, 140) having a solid body with a vent outlet at a central location leading to an inner chamber (150, 152), the vent manifold (50, 140) having a plurality of evenly spaced internal passages extending outward from the inner chamber to multiple vent inlets distributed evenly around an outer periphery of the body, wherein the solid body of the vent manifold (50, 140) is cylindrical, and the vent conduits initially project radially outward from the vent manifold (50, 140) body and bend 90° downward toward a respective receptacle gas vent, characterized in that the solid body of the vent manifold (50, 140) is separate from but disposed adjacent and secured in axial alignment with respect to the fluid distribution manifold (24, 142); and a plurality of vent conduits each of which connects one of the vent inlets of the vent manifold (50, 140) to one of the receptacle gas vents. a fluid distribution manifold (24, 142) comprising a solid body having a fluid inlet in communication with the single fluid source at a central location leading to an inner chamber (174, 176), the fluid distribution manifold (24, 142) having a plurality of evenly spaced internal passages extending outward from inner apertures opening to the inner chamber to multiple fluid outlets distributed evenly around an outer periphery of the body, wherein the solid body of the fluid distribution manifold (24, 142) has a cylindrical shape with the internal passages and fluid outlets extending radially outward from the inner chamber, the outlet conduits initially projecting radially outward from the body and bending 90° downward; a plurality of outlet conduits fluidly connected to the fluid outlets; a plurality of receptacles each of which has an outlet conduit connected thereto, wherein fluid provided to the fluid inlet of the fluid distribution manifold (24, 142) is distributed evenly through the internal passages, fluid outlets, and outlet conduits into the receptacles; a gas vent in each receptacle; a vent manifold (50, 140) disposed adjacent the fluid distribution manifold (24, 142), the vent manifold (50, 140) having a solid body with a vent outlet at a central location leading to an inner chamber (150, 152), the vent manifold (50, 140) having a plurality of evenly spaced internal passages extending outward from the inner chamber to multiple vent inlets distributed evenly around an outer periphery of the body, wherein the solid body of the vent manifold (50, 140) is cylindrical, and the vent conduits initially project radially outward from the vent manifold (50, 140) body and bend 90° downward toward a respective receptacle gas vent, characterized in that the solid body of the vent manifold (50, 140) is separate from but disposed adjacent and secured in axial alignment with respect to the fluid distribution manifold (24, 142); and a plurality of vent conduits each of which connects one of the vent inlets of the vent manifold (50, 140) to one of the receptacle gas vents.
