Reply to comment by Mobely in Removing dishwasher air gap-bad idea? by capnsmartypantz

This is my understanding as well. Nothing to do with the pumped wastewater reentering the dishwasher.

What I'm confused about is, doesn't every dishwasher have a check valve on the drain pump outlet, or in the drain hose?

I don't think a dishwasher can have a check valve as they are designed to remove food particles. A check valve might get clogged pretty quick under those use conditions.

I'm talking out of my ass ofcourse, some models might have those valves since some models have a built in high loop. But code is code, and it's meant to protect the average user. I think the manufacturer would have to send a lobbyist to ask every state, city, and township to update their code as well.

interesting. I know for certain my Bosch has a check valve, but it also has a metal mesh filter to prevent food particles from ending up in the sump.
