How Do I Install An Air Gap On Dishwasher?
Air gaps are a code issue varying from area to area. Here in S. Fl. you never see them. In Detroit they are a special ftg installed through the sink deck. The dirty water means) your drain is syphoning back. Extend the drain upward till it touches the sink top from below. Now it can’t back up unless the sink is full to the top with water. I fwhen the dishwasher drains you see the level in the sink drain or disposal rise more than a fraction of an inch, it’s time to clean the drain.
My wife didn’t want the anti-siphon valve to sit on top of the kitchen counter, so I installed it according to directions, with the hose from the dishwasher to the valve, and the outflow from the valve going into my gargbage disposer. But I located the valve as high up as I could, up just under the bottom of the countertop, and fastened it there with a strap. It works fine and was a lot easier than drilling a hole in the countertop.
