I thought I would consult the experts on the proper method of eliminating the dishwasher air gap from above the kitchen sink.
I will usually route the drain line into the disposal. Sometimes I will take the whole air gap assembly and mount it as high as possible under the cabinet. So far I haven’t had any callbacks, however, I just don’t know what the standard procedure is. Are there any advantages/drawbacks to either method?
I’ve seen air gaps that vent outside. I’ve seen a dedicated p-trap assembly for the dishwasher gray water. I’ve seen a small 1/2 inch copper pipe sticking out of the wall that the rubber hose clams onto. I don’t even know where that copper pipe drains to, perhaps the yard? I was wondering if there was a proper way to remove the unsightly air gap atop the kitchen sink.
Thanks in advance for all your input,
–Andrew

Here in NW OH I have yet to see a visible air gap installation. For that matter, have yet to see anyone do an install with an air gap. No inspectors have asked or mentioned it. I understand the reason for it, but in 35 yrs, nope. Perhaps in a new code adoption it will be come commonplace here.
