A check valve 12 includes a circular check valve flange 20 that circumscribes a central axis and defines an outer perimeter of the check valve 12. The check valve also includes a first tab 22 that extends radially outward from the check valve flange and has a first circumferential width and a first radial length. The check valve also includes a second tab 24 that extends radially outward from the check valve flange and has a second circumferential width and a second radial length. The first circumferential width is different than the second circumferential width and the first radial length is greater than the second radial length. The first tab 22 and the second tab 24 of the check valve are disposed about the check valve flange 20 at an angle other than 180 degrees apart. |
