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 method for manufacturing a flange apparatus that connects between a plumbing fixture discharge and waste drainpipe outlet, comprising: providing a flange; andproviding a sleeve that couples to the flange, the sleeve being formed of a flexible material such that the sleeve is capable of at least ten degrees of deflection while maintaining a cross-sectional shape of a lower portion of the sleeve, the sleeve including: a lip extending inwardly from an upper portion of the sleeve, the lip being sufficiently flexible to deflect downward when engaged by the plumbing fixture discharge; andone or more sealing elements disposed about the lower portion of the sleeve that engage an inside diameter of the waste drainpipe outlet. 2. The method according to claim 1, wherein the sleeve is integrally formed with the flange. 3. The method according to claim 1, further comprising removably connecting the sleeve to the flange. 4. The method according to claim 1, further comprising disposing the sleeve in the flange. 5. The method according to claim 1, wherein the providing the sleeve includes forming the sleeve with a first material, andthe providing the flange includes forming the flange with a second material different from the first material. 6. The method according to claim 1, wherein the providing the sleeve includes forming the lip such that the lip has a first unengaged position and a second engaged position, andan end of the lip is positioned further in an upward direction in the first unengaged position than in the second engaged position. 7. The method according to claim 1, wherein the providing the sleeve includes forming the sleeve of the flexible material. 8. The method according to claim 1, wherein the providing the sleeve includes forming the one or more sealing elements on an end of the lower portion of the sleeve. 9. The method according to claim 1, wherein the providing the sleeve includes forming the one or more sealing elements such that the one or more sealing elements define a longitudinal distance, andthe one or more sealing elements has a maximum diameter at its upper longitudinal end and generally decreases in diameter to its lower longitudinal end. 10. The method according to claim 1, wherein the sleeve includes an outward flange that seats on the flange and extends from the upper portion. 11. A flange apparatus that connects between a plumbing fixture discharge and waste drainpipe outlet, comprising: a flange; anda sleeve that couples to the flange, the sleeve being formed of a flexible material such that the sleeve is capable of at least ten degrees of deflection while maintaining a cross-sectional shape of a lower portion of the sleeve, the sleeve including: a lip extending inwardly from an upper portion of the sleeve, the lip being sufficiently flexible to deflect downward when engaged by the plumbing fixture discharge; andone or more sealing elements disposed about the lower portion of the sleeve that engage an inside diameter of the waste drainpipe outlet. 12. The flange according to claim 11, wherein the sleeve is integrally formed with the flange. 13. The flange according to claim 11, wherein the sleeve is disposed in the flange. 14. The flange according to claim 11, wherein the sleeve includes a first material, andthe flange includes a second material different from the first material. 15. The flange according to claim 11, wherein the lip has a first unengaged position and a second engaged position, andan end of the lip is positioned further in an upward direction in the first unengaged position than in the second engaged position. 16. The flange according to claim 11, wherein the sleeve includes an outward flange that seats on the flange and extends from the upper portion. 17. A method for substantially sealing a plumbing fixture discharge to a waste drainpipe outlet, comprising: providing a flange;providing a sleeve that couples to the flange, the sleeve being formed of a flexible material such that the sleeve is capable of at least ten degrees of deflection while maintaining a cross-sectional shape of a lower portion of the sleeve, the sleeve including: a lip extending inwardly from an upper portion of the sleeve, the lip being sufficiently flexible to deflect downward when engaged by the plumbing fixture discharge; andone or more sealing elements disposed about the lower portion of the sleeve that engage an inside diameter of the waste drainpipe outlet;using the lip of the sleeve to substantially seal the plumbing fixture discharge to the sleeve; andusing the one or more sealing elements of the sleeve to substantially seal the waste drainpipe outlet to the sleeve. 18. The method according to claim 17, wherein the using the lip includes positioning the lip to be in contact with the plumbing fixture discharge. 19. The method according to claim 17, wherein the using the one or more sealing elements includes positioning the one or more sealing elements to be in contact with the waste drainpipe outlet. 20. The method according to claim 17, wherein the using the one or more sealing elements includes inserting the lower portion of the sleeve into the waste drainpipe outlet. 21. The method according to claim 17, further comprising seating the flange against a flooring surface. 22. The method according to claim 17, further comprising positioning the sleeve inside the flange. 23. The method according to claim 17, wherein the sleeve includes an outward flange that seats on the flange and extends from the upper portion.
