My dishwasher will drain into a trap that is quite a ways from my sink, that serves only the dishwasher. I have 1-1/2 ABS with a dishwasher nipple on the side. Above the nipple I need an air inlet to provide an "air gap". I am trying to decide what to do.
Maybe I can build a snorkel out of 1/2 copper to exent above the ABS.
Or I could install a cheater vent at the top.
What would be best setup to ensure the air-gap, but limit he possibility a rush of dishwasher outflow could back-up?
