My garbage disposal drain is about 1" lower than the drain connect sticking out of the wall drain? Will it still work?

Try turning trap around backwards.

Is the actual outlet of the GD lower than the Inlet at the wall ? Does your GD have the 90 degree discharge pipe attached to the GD ?

Now a picture would really be helpful. Is the wall stubout higher then the GD outlet opening the curved pipe connects into?
