5. The drain valve assembly of claim 4 , wherein the second portion of the wall formation and the third portion of the wall formation are spaced apart from one another.

6. The drain valve assembly of claim 1 , wherein the plug member includes a first rod member having a central axis aligned with the outlet opening of the first portion of the wall formation.

7. The drain valve assembly of claim 6 , wherein the first rod member includes a projection formation connected to the first rod member.

8. The drain valve assembly of claim 7 , wherein the projection formation extends in a first transverse direction with respect to the first rod member.

9. The drain valve assembly of claim 8 , wherein the projection formation is encapsulated within a seal member.

10. The drain valve assembly of claim 9 , wherein the first portion of the wall formation defines a projection member which extends about the outlet opening and faces the plug member such that seal member engages the projection member with the plug member in the first position.

11. The drain valve assembly of claim 9 , wherein the seal member has a first width dimension which is greater than a second width dimension of the outlet opening of the first portion of the wall formation.

12. The drain valve assembly of claim 9 , further includes:

a second portion of the sidewall of the drain which extends in a second transverse direction from the sidewall of the drain forming a cylindrical formation with a second opening formed by the cylindrical formation which extends away from the sidewall of the drain;

the second opening formed by the cylindrical formation is aligned with a third opening defined by sidewall of the second portion of the drain; the first rod member extends through the second opening formed by the cylindrical formation and the first rod member extends away from the drain;

a cap member positioned and releasably secured to the cylindrical formation with the cap member defining a fourth opening, with the first rod member extending through the fourth opening of the cap member; and

a compression spring positioned between the seal member and the cap member such that with the plug member in the first position, the compression spring applies a force to the plug member abutting the plug member against the first portion of the wall formation and with the plug member in the second position, the compression spring becomes shorter in length thereby storing energy for returning the plug member into the first position.

13. The drain valve assembly of claim 12 , wherein with the first rod member extending through the fourth opening formed by the cap member and beyond the cap member and away from the drain, the first rod member defines a fifth opening further including a second rod member positioned within the fifth opening defined by the first rod member and the second rod member extends in a second direction toward a faucet assembly which includes a housing.

14. The drain valve assembly of claim 13 , wherein:

the second rod member extends through a channel defined by the housing such that the second rod member extends through the housing; and

the channel has a first end portion which has a third width dimension which is positioned closer to the first rod member than a second end portion of the channel which has a fourth width dimension less than the third width dimension.

15. The drain valve assembly of claim 14 , wherein:

with a portion of the second rod member, which extends beyond and away from the housing having a force applied to the portion of the second rod member moving the portion of the second rod member in a direction toward the basin, a channel sidewall within the channel contacts the second rod member resulting in the second rod member, which is positioned within the fifth opening of the first rod member, moving the first rod member in a direction away from the drain and moving the plug member to the second position wherein the plug member is positioned spaced apart from the first portion of the wall formation placing the outlet opening in an open position; and

with the force removed from the portion of the second rod member, the compression spring pushes the plug member to the first position closing the outlet opening and moving the first rod member toward the drain.

16. A method for installing a drain valve assembly to a basin, comprising:

positioning a drain aligned with an opening in the basin with the drain having a sidewall, which defines a first opening, wherein the first opening is in fluid communication with the basin and with a first portion of the drain; wherein:

the sidewall includes a wall formation positioned within the drain which extends across the first opening separating the first portion of the drain from a second portion of the drain;

a first portion of the wall formation extends in a first direction away from the basin and defines an outlet opening which extends through the first portion of the wall formation in a direction transverse to the first direction; and

a plug member aligned with the outlet opening and movable from a first position with the plug member abutting the first portion and closing the outlet opening and to a second position wherein the plug member is positioned spaced apart from the first portion placing the outlet opening in an open position providing fluid communication between the first portion and the second portion of the drain.

17. The method of claim 16 , wherein the wall formation further includes:

a second portion extending from the sidewall from one side of the drain and across a first portion of the first opening of the drain and connecting to the first portion;

a third portion extending from a second opposing side of the sidewall of the drain and across a second portion of the first opening of the drain and connecting to the first portion; and

the second portion of the wall formation and the third portion of the wall formation are spaced apart from one another.

18. The method of claim 16 , wherein the plug member further includes:

a first rod member having a central axis aligned with the outlet opening of the first portion of the wall formation;

the first rod member includes a projection formation connected to the first rod member;

the projection formation extends in a first transverse direction to the first rod member; and

the projection formation is encapsulated within a seal member.

19. The method of claim 18 , wherein the seal member has a first width dimension which is greater than a second width dimension of the outlet opening of the first portion of the wall formation.

20. The method of claim 19 , wherein:

a second portion of the sidewall of the drain which extends in a transverse direction from the sidewall of the drain forming a cylindrical formation with a second opening formed by the cylindrical formation which extends away from the sidewall of the drain;

the second opening formed by the cylindrical formation is aligned with a third opening defined by sidewall of the second portion of the drain; the first rod member extends through the second opening formed by the cylindrical formation and the first rod member extends away from the drain;

a cap member releasably secured to the cylindrical formation with the cap member defining a fourth opening with the first rod member extending through the fourth opening of the cap member; and

a compression spring positioned between the seal member and the cap member such that with the plug member in the first position, the compression spring applies a force to the plug member abutting the plug member against the first portion of the wall formation and with the plug member in the second position, the compression spring becomes shorter in length thereby storing energy for returning the plug member to the first position.
