Abstract: A plumbing system includes a tub having a drain fixture lodged within a floor drain opening. The drain fixture comprises a body member beneath the floor and a drain cap member inserted into an exposed open inlet of the body member. The body member has a passageway extending between the open inlet and a downstream open outlet in communication with a sewer. A pipe connected to the body member between the inlet and outlet has one end in communication with the passageway and another end in communication with an overflow opening in the tub above the drain opening to vent the passageway. The drain cap member moves between a first position allowing liquid to flow through the passageway and a second position preventing the flow of liquid through the passageway.

Abstract: The flushing arrangement has a toilet bowl (2) which has an inlet (3) and an outlet (21) and, between these, means (8, 20) for generating a pulse. By means of the pulse, water (13) which is present in a U-bend (4) and forms a stench trap can be accelerated, for a flushing operation, in the direction of the outlet (21). Said means (8, 20) are arranged in the descending region of the toilet bowl (2) and, during flushing, generate a downwardly directed flow cone (14, 14?). The flow narrows downwardly and at a saddle point (26) forms a wall jet (28) which cleans the U-bend (4) particularly thoroughly.
