3. The adapter of claim 1 , wherein the sealing material is rubber.
4. An apparatus, comprising:
a basket structure having a first end and a second end, the first end being configured to couple to a dual flush canister for a toilet, the dual flush canister being configured to provide both a short flush and a long flush of the toilet;
a plurality of tabs extending inward toward a center axis of the basket structure, the plurality of tabs being configured to engage a lip of a flush opening of a flush valve previously installed in the toilet; and
a plurality of support legs extending between the first end and the second end defining a plurality of passageways from an exterior of the basket structure to the flush opening.
5. The apparatus of claim 4 , wherein the lip of the flush opening is defined by a channel around an outer surface of the flush opening.
6. The apparatus of claim 4 , wherein the plurality of tabs secure the basket structure in position relative to the flush opening.
7. The apparatus of claim 4 , wherein the first end is coupled to the dual flush canister via a plurality of mating ears fitting within an annular groove.
8. The apparatus of claim 7 , wherein the plurality of mating ears slide within the annular groove.
9. The apparatus of claim 4 , wherein the dual flush canister can be rotated with respect to the basket structure.
10. The apparatus of claim 4 , wherein the plurality of tabs comprise tabs positioned around the flush opening to provide structural support.
11. The apparatus of claim 4 , wherein the plurality of tabs comprise at least four tabs.
12. The apparatus of claim 4 , wherein the plurality of support legs further comprise at least four support legs.
13. The apparatus of claim 4 , wherein the plurality of tabs are positioned at the second end of the basket structure.
14. An apparatus, comprising:
a dual flush canister configured to provide both a short flush and a long flush of a toilet;
a basket structure having a first end and a second end, the first end being configured to couple to the dual flush canister;
a plurality of tabs extending inward toward a center axis of the basket structure, the plurality of tabs engaging a lip of an adapter flush opening of a flush valve adapter;
a plurality of support legs extending between the first end and the second end defining a plurality of passageways from an exterior of the basket structure to the adapter flush opening; and
the flush valve adapter further comprising:
a flange configured to mate to a flush valve opening of a previously installed flush valve in the toilet, the flange being offset at an angle with respect to the adapter flush opening; and
a sealing material forming a seal between the flange and the flush valve opening.
15. The apparatus of claim 14 , wherein the sealing material is disposed against a mating surface of the flange.
16. The apparatus of claim 14 , wherein the plurality of tabs secure the basket structure in position relative to the flush opening.
17. The apparatus of claim 14 , wherein the first end is coupled to the dual flush canister via a plurality of mating ears fitting within an annular groove.
18. The apparatus of claim 17 , wherein the plurality of mating ears slide within the annular groove.
19. The apparatus of claim 14 , wherein the dual flush canister can be rotated with respect to the basket structure.
20. An apparatus, comprising:
a dual flush canister configured to provide both a short flush and a long flush of a toilet;
a basket structure having a first end and a second end, the first end being configured to couple to the dual flush canister;
a plurality of support legs extending between the first end and the second end defining a plurality of passageways from an exterior of the basket structure to a flush opening; and
a circular support structure configured to align the dual flush canister with the flush opening, the circular support structure having an inner diameter greater than an outer diameter of a toilet overflow tube.
21. The apparatus of claim 20 , wherein the circular support structure is mounted on the toilet overflow tube.
