Abstract

A toilet seal for sealing between a plumbing fixture discharge and a waste drainpipe outlet is described. The toilet seal comprises a flange member having an inwardly extending flexible lip and one or more raised ridges defining an annular seal extending upwardly from an upper surface of the flange member. The toilet seal further includes a radiused wall extending downwardly from the flange member, which cooperates with the flange member to define a cavity for receiving a compressible member. The toilet seal further comprises a flexible sleeve extending downwardly from the radiused wall. Related methods are described.

Abstract

A flange apparatus operable to connect the discharge of a plumbing fixture to the waste drain pipe of a drainage system. In an embodiment, the flange apparatus includes a flange and a flexible sleeve disposed through a central opening of the flange, in which a first portion of the flexible sleeve is seated on the flange. The flange further includes arm portions, each having an aperture defined therethrough. The surfaces of the apertures are substantially smooth, and the apertures are operable to receive fasteners. In an embodiment, the arm portions may be made of threadable materials, and the fasteners may have thread-forming fasteners such that threads are formed in the arm portions when the thread- forming fastener is received in the aperture of the arm portions.

Abstract

The present disclosure generally relates to flexible drainage trap assemblies and methods for constructing and installing such drainage traps. In one exemplary embodiment, a flexible drainage trap assembly includes a plumbing fixture connector, a discharge joint, and a trap portion connecting the plumbing fixture connector and discharge joint. The trap portion is shaped in such a way that it is operable to retain a pool of water inside the trap portion. The disclosed flexible drainage assemblies include a flexible portion that has a substantially smooth inner surface.

Abstract

The present disclosure generally relates to improved water closet flanges and methods for installing such water closet flanges. In one exemplary embodiment, an improved water closet flange apparatus includes a flexible conduit portion (i.e. sleeve) and an integral membrane element sealing the top opening of the flexible sleeve. The membrane element is made of flexible materials such that the membrane element may be removed without breaking into pieces. In one embodiment, the integral membrane element includes indented portions to facilitate its removal. In another embodiment, the flange apparatus includes an outer flange connected to the flexible sleeve. Related methods for installing the disclosed flange apparatus between plumbing fixture discharges and waste drainpipes are also described.

Abstract

The present disclosure generally relates to improved water closet flanges and methods for installing such water closet flanges. In one exemplary embodiment, an improved water closet flange apparatus includes an outer flange and a flexible conduit portion (i.e. sleeve) extending downwardly therefrom. The flexible sleeve has a sufficient degree of flexibility to accommodate connection between offset, misaligned, angled, or otherwise incongruous plumbing fixture discharges and waste drain pipe outlets. In one embodiment, the flexible sleeve includes at least one corrugated portion to aid the desired flexibility. An upper portion of the flexible sleeve may include an inwardly extending lip portion to accommodate the desired seal between the plumbing fixture discharge and the flange apparatus. Related methods for installing the disclosed flange apparatus between plumbing fixture discharges and waste drainpipes are also described.

Abstract

An improved water closet flange for connection to a plumbing fixture comprises an outer flange (10) connected to a flxible sleeve (12), in which is attached an O-ring type gasket (30). The improved flange allows the connection between a toilet bowl discharge and a waste drain pipe outlet that is offset, horizontally oriented, or diagonally placed. The O-ring type gasket is disposed on the exterior of the flexible sleeve (12) and the inner surface of the waste drain pipe for providing a tight seal.
