I have a thick cast iron sink and do not want to drill a new hole, but I need to do something with my dishwasher "air gap" ( I am using the fourth hole for my water purifier) I am thinking of removing the air gap and draining the dishwasher straight into the garbage disposal. Is this a good or bad idea. I presently have the air gap tide up as high as I can under the sink, but on occasion it does leak.
