Abstract

A wastewater strainer is provided that includes a strainer body that has at least one opening that enhances fluid flow through the strainer body and the wastewater plumbing to which it is interconnected. The strainer body includes a flange for engagement to the inner portion of a bathtub and a hub that is spaced from a lower edge of the strainer body.

First claim

What is claimed is:

1. A wastewater strainer operable to be provided in a drain elbow, the wastewater strainer comprising:
a body having an upper edge and a lower edge, and at least a portion of the body comprising a sidewall;
a flange extending from said upper edge;
at least one extension extending downwardly from the lower edge away from the flange;
an arm interconnected on a first end to said at least one extension and on a second end to a centrally-located hub positioned below the lower edge of said body, the hub having an aperture adapted to receive a threaded post or carrier associated with a drain stopper;
wherein said hub is provided in a fixed position relative to the body by the at least one extension, and wherein at least one opening for fluid flow is provided between the lower edge of the body and the hub;
wherein the hub comprises a thickness that is greater than a thickness of the arm; and
a plurality of holes extending through the sidewall of the body, the plurality of holes operable to decrease the amount of fluid that must circumvent the sidewall.

2. The wastewater strainer of claim 1 , wherein a distance between a lower surface of said flange and said lower edge of said body is between 0.25 inches and 1.0 inches.

3. The wastewater strainer of claim 1 , wherein a distance between said lower edge of said body and a bottom surface of said hub is at least 0.5 inches.

4. The wastewater strainer of claim 1 , wherein the at least one extension comprises first and second extensions.

5. The wastewater strainer of claim 1 , wherein the sidewall of the body comprises external threads.

6. The wastewater strainer of claim 1 , wherein said at least one extension is angled relative to said flange.

7. A wastewater strainer, comprising:
a body having an upper edge and a lower edge;
a flange;
at least one extension extending from said lower edge;
a hub spaced apart from said lower edge of said body, said hub being interconnected to said at least one extension, and said hub having an aperture adapted to receive a threaded post;
wherein a distance between a lower surface of said flange and said lower edge of said body is between 0.25 inches and 1.0 inches, and wherein the wastewater strainer is operable to be provided in a drain elbow;
a hole extending through a sidewall of the body, the hole operable to decrease the amount of fluid that must circumvent the sidewall; and
wherein said hub is provided in a fixed position relative to the body by the at least one extension, and wherein at least one opening for fluid flow is provided between the lower edge of the body and the hub.

8. The wastewater strainer of claim 7 , wherein said body is threaded.

9. The wastewater strainer of claim 7 , wherein said at least one extension is angled relative to said flange.

10. The wastewater strainer of claim 7 , wherein a distance between said lower edge of said body and a bottom surface of said hub is at least 0.5 inches.

11. The wastewater strainer of claim 7 , wherein the flange extends outwardly from said upper edge.

12. A wastewater strainer comprising:
a body having an upper edge and a lower edge, and at least a portion of the body comprising a sidewall;
a flange extending from the upper edge;
at least one extension connected to at least a portion of the lower edge;
an arm interconnected on a first end to the at least one extension and on a second end to a centrally-located hub positioned below at least a portion of the lower edge of the body, said hub having an aperture adapted to receive a threaded post or carrier associated with a drain stopper, wherein the hub is provided in a fixed position relative to the body by the at least one extension, and wherein at least one opening for fluid flow is provided between at least a portion of the lower edge of the body and the hub; and
at least one additional opening that is at least partially defined within the sidewall.

13. The wastewater strainer of claim 12 , wherein a distance between a lower surface of the flange and the lower edge of the body is between 0.25 inches and 1.0 inches.

14. The wastewater strainer of claim 12 , wherein the body is threaded.

15. The wastewater strainer of claim 12 , wherein the at least one extension is angled relative to the flange.

16. The wastewater strainer of claim 12 , wherein a distance between the lower edge of the body and a bottom surface of the hub is at least 0.5 inches.

17. The wastewater strainer of claim 12 , wherein the at least one extension comprises a first extension and a second extension.

18. The wastewater strainer of claim 12 , wherein the flange extends from the upper edge of the body.
