Would a wye installed on a standpipe, with the a short stub on the diagonal branch to prevent splashing, and a longer stub going upward as an inlet, be an effective airgap? I would think the flood line would be the top of the diagonal stub, so siphoning shouldn't happen unless your drain tubes stick too far into the inlet.
