Is there such a thing as an undercounter air gap?
Is an air gap needed or required if drains to disposal?

It depends on the jurisdiction.Is there such a thing as an undercounter air gap?

Block the drain, and run the water. At the flood level, the water will stop rising, and will spill onto the floor.Reach4 thanks!
So reading that code...what is considered the flood level of the sink?
The air gap is above the counter.
If you don't have an air gap, at least loop the drain from the dishwasher as high as you can under the countertop before installing to a disposer or a trap.
An airgap below the counter isn't a good idea. They can overflow.
You can get a combination air gap with soap/lotion dispenser.Ok I'll put in the air gap on the counter it's in an island sink with granite and thought it would be nice to have fewer obstruction for the sink/counter etc.
They show a standpipe for the dishwasher. Is that your intention?Checked with City of Littleton code/inspectors and they said it's fine to do the undercounter air gap as shown in the State code here:
