Hi all, I am replacing a dishwasher and relocating it on the other side of the sink. I have been told that the current set up does not meet code as the dishwasher drains into the garbage disposal with no air gap. I am also removing the disposal in the new install as it wont fit under the new deeper single bowl sink.
My municipality uses 2021 residential building code but I believe it uses 2014 IL plumbing code. I am getting a bosch dishwasher. I cant figure if I am required to have an air gap or can do without (high loop) or have other alternative option.
Below is the section that I could find on the topic. It says air gap or ABV or DuC. This sounds ultra complicated. Anyone willing to translate?
I already have a faucet, a tap water faucet and a bottle sprayer on the counter, would rather avoid another item clogging the space.
Also I am assuming I can simply use a disdwasher WYE tailpiece to connect the waste pie into the sink drain. is that correct?

Section 890.770 Dishwashing Machines
a) Domestic Dishwasher (Private Residence). When a domestic dishwashing machine drain line is connected to the house side of a trap from a sink, the drain from the dishwasher shall be carried up to the underside of the spill rim of the sink. Dishwashing machines shall discharge separately into a trap or tail piece of the kitchen sink and shall not connect to the food waste disposal unit.
b) Water Supply Connection. The water supply to commercial dishwashing machines shall be connected through an air gap or by means of proper backflow protection, e.g., a non-pressure type (atmospheric) vacuum breaker or a dual check valve backflow preventer assembly (DuC), depending upon the circumstances.
c) Commercial dishwashing machines shall indirectly discharge to a proper receptor connected to the drainage system or as permitted in Section 890.1010(a).
d) Hot Water. A commercial dishwashing machine or similar dishwashing equipment that relies upon hot water for sanitizing dishes and utensils, rather than chemicals for sanitizing, shall provide rinse water at 180 degrees F., except for a single-tank, stationary-rack, single temperature dishwashing machine which shall provide a rinse water temperature of 165 degrees F., in accordance with Section 750.830(h) of the "Food Service Sanitation Code" (77 Ill. Adm. Code 750).
