High loop in dishwasher

high loop in dishwasher

We had a dishwasher installed with a " high loop " rather than installing an air gap. I know I've read here that either works. I believe code in some  Dishwasher High Loop Placement.
What is the difference between a dishwasher high loop and an air gap (anti siphon)? Which one is a better method to prevent water entering.
I was installing a dishwasher for a friend of mine this evening and while looking through the directions it made no mention of a high loop. Originally Posted by roconnor.
