Water stated coming out the drain air gap.And none of the pipes are cloged and the gap itself is clear.I replaced the tube from the drain air gap to the garbage disposal and not sure if I got that to long.Could that have anything to do with it backing up???
You probably got it to low. Raise the pipe as high as it will go to the underside of sink, if that dont work you will have to install one of those airgap fitting.
