air gap

I live in a very rural area where there are almost zero reliable contractors/plumbers. Almost everyone I’ve hired over the last three years, I’ve had to redo some (or all) of their work. So I’ve relied on forums like this (THANK YOU!) and hundreds of hours of research to try and find decent...

I am installing a dishwasher air gap in a granite countertop and the undermount sink flange is very close to the hole for the air gap. So the bottom nut only contacts the sink flange on one side and does not make contact with the countertop on the opposite side. There is about a 1/8 inch...

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