Plunger

1. A plunger adapter comprising:

a flange having a length, a width and a thickness, wherein the length is greater than the width to cover an elongated toilet trapway;

a peripheral seal extending away from the flange to seal with the elongated toilet trapway, wherein the peripheral seal is radially asymmetrical; and

a cylindrical receptacle formed into the flange and spaced apart from the seal for cooperation with a radially symmetrical plunger;

wherein the seal extends centrally inward;

wherein the flange is symmetrical along a first plane and symmetrical along a second plane perpendicular to the first plane; and

wherein the flange further comprises a pair of parallel sides.

2. The plunger adapter of claim 1 wherein the flange is shaped as a pair of semi-circles each having a radius that is half of the width of the flange, the semi-circles being spaced apart in a direction of the length of the flange.

3. The plunger adapter of claim 1 wherein the pair of parallel sides are spaced apart in a direction of the width of the flange.

4. The plunger adapter of claim 1 wherein the seal is tapered inward away from the flange.

5. The plunger adapter of claim 1 wherein the seal extends from a periphery of the flange.

6. The plunger adapter of claim 1 further wherein the receptacle comprises a peripheral ring extending from the flange with an aperture formed therein.

7. The plunger adapter of claim 6 further comprising a plurality of structural ribs, each oriented upon the flange and extending to an intersection of the flange and the peripheral ring.

8. The plunger adapter of claim 1 wherein the seal has an opening therein facing away from the flange.

9. The plunger adapter of claim 8 wherein a cavity is provided within the flange and the seal for fluid communication through the flange, the seal and the seal opening.

10. A plunger assembly comprising:

a radially symmetrical plunger; and

a plunger adapter comprising:

a flange having a length, a width and a thickness, wherein the length is greater than the width to cover an elongated toilet trapway,

a peripheral seal extending away from the flange to seal with the elongated toilet trapway, wherein the peripheral seal is radially asymmetrical, and

a cylindrical receptacle formed into the flange and spaced apart from the seal for cooperation with the radially symmetrical plunger,

wherein the flange is symmetrical along a first plane and symmetrical along a second plane perpendicular to the first plane, and

wherein the flange further comprises a pair of parallel sides.

11. The plunger assembly of claim 10 wherein the seal extends centrally inward from a periphery of the flange.
