Abstract: A coupling assembly for a closet carrier system for a water closet includes a central pipe member having a first end and a second end, and an interior surface defining a hollow interior; an adapter member separate from the central pipe member and connected to the second end of the central pipe member, the adapter having an interior surface defining a hollow interior and configured to adjustably connect the coupling assembly to a faceplate of the system; and a horn coupling member configured to be connected to the first end of the central pipe member. At least the hollow interior of the central pipe member and the hollow interior of the adapter member form an internal passage of the coupling assembly. The horn coupling member is configured to be connected to a water closet to place the internal passage of the coupling assembly in fluid communication with the water closet.

Abstract: A closet carrier for a water closet includes a faceplate, an adjustable coupling connected to and extending from the faceplate, the adjustable coupling being configured to be connected to the water closet, at least two vertical supports adjustably connected to the faceplate for supporting the system on a floor surface, and a fitting connected to the faceplate. The fitting includes an endplate, an inlet defined within the endplate, an intermediate portion, and a main body defining a main passageway. The fitting is connected to the faceplate by the endplate such that the inlet is in fluid communication with the adjustable coupling. The main passageway is placed in fluid communication with the inlet by the intermediate portion. The intermediate portion of the fitting is configured to accelerate a velocity of a flow of waste fluid from the inlet to the main passageway.
