I got a call from Lowes home improvement store tonight. The owner of a house I inspected was there and the Lowes employee called me at the owner’s instruction to try to convince me that an air gap isn’t required for a dishwasher if the drain line is looped up high. (I wrote up the lack of one in his house.)
Can an air gap be omitted? If not required, how does that square with:
IRC SECTION P2717 / DISHWASHING MACHINES
P2717.1 Protection of water supply. The water supply for
dishwashers shall be protected by an air gap or integral
Does everyone cite the lack of a dishwasher air gap? Do you cite it as a significant issue or an “informational” item?
