here is a pic of the issue. the new sink on the right, will require the drain on the disposal to be lower than the drain in the wall, will this cause a backflow problem like the guy at the hardware store suggested? or will i be fine?

the part that is pink is what would need to be added in to make it work, but that also puts the disposal on the drain at a lower plane than the disposal's outlet
