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 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.

1. A seal for connecting between a plumbing fixture discharge and a waste drainpipe outlet, comprising: an outer flange including a groove defined in an upper surface of the outer flange, and including a plurality of apertures to receive fasteners;a sleeve disposed in the groove of the outer flange,
1. A seal for connecting between a plumbing fixture discharge and a waste drainpipe outlet, comprising: an outer flange including a groove defined in an upper surface of the outer flange, and including a plurality of apertures to receive fasteners;a sleeve disposed in the groove of the outer flange, the sleeve having an upper end and a lower end, the lower end of the sleeve being sufficiently flexible to permit distortion of the lower end of the sleeve;an inwardly extending flexible lip disposed at the upper end of the sleeve, the lip being sufficiently flexible to deflect downward relative to the upper surface of the outer flange when engaged by the plumbing fixture discharge; andat least one flexible seal operable to provide a seal with the waste drainpipe outlet, whereinthe sleeve is integrally formed with the outer flange as a single piece. 2. The seal of claim 1, wherein the flexible seal is formed of a soft plastic material. 3. The seal of claim 1, wherein the outer flange is operable to seat against a surface disposed substantially between the plumbing fixture discharge and the waste drainpipe outlet. 4. The seal of claim 1, wherein the flexible seal is disposed between the flexible lip and the outer flange. 5. The seal of claim 1, wherein the flexible seal is a ring formed of a soft plastic material. 6. The seal of claim 1, wherein an outer edge of the outer flange is circular. 7. The seal of claim 1, wherein the lower end of the sleeve has a hardness in the range of 35 shore A to 90 shore A. 8. The seal of claim 1, wherein the lower end of the sleeve has a hardness in the range of 35 shore A to 65 shore A. 9. The seal of claim 1, wherein the lower end of the sleeve has a hardness of about 50 shore A. 10. An apparatus for connecting between a plumbing fixture discharge and a waste drainpipe outlet, comprising: an outer flange including a groove defined in an upper surface of the outer flange, and including a plurality of apertures to receive fasteners;a sleeve disposed in the groove of the outer flange and integrally formed with the outer flange, the sleeve having upper and lower portions, the upper portion comprising an inwardly extending flexible lip, wherein the lip is sufficiently flexible to deflect downward relative to the upper surface of the outer flange when engaged by the plumbing fixture discharge; andat least one flexible seal operable to provide a seal with the waste drainpipe outlet disposed. 11. The seal of claim 10, wherein the flexible seal is formed of a soft plastic material. 12. The seal of claim 10, wherein the flexible seal is disposed below the flexible lip. 13. The seal of claim 10, wherein the flexible seal is a ring formed of a soft plastic material. 14. A method for sealing between a plumbing fixture discharge and a waste drainpipe outlet, comprising: providing a seal, the seal comprising: an outer flange including a groove defined in an upper surface of the outer flange, and including a plurality of apertures to receive fasteners;a sleeve disposed in the groove of the outer flange, the sleeve having an upper end and a lower end, the lower end of the sleeve being sufficiently flexible to permit distortion of the lower end of the sleeve, and the sleeve being integrally formed with the outer flange as a single piece;an inwardly extending flexible lip disposed at the upper end of the sleeve; andat least one flexible seal disposed proximate to the lip;disposing the seal between the plumbing fixture discharge and the waste drainpipe outlet; andseating the plumbing fixture discharge onto the flexible lip, thereby deflecting the lip downward relative to the upper surface of the outer flange.
