After a new sink install (sink has one drain) , my plumber told me he couldn't connect my dishwasher drain hose to my disposal because of a change in code. So he added a second trap and connected the dishwasher drain to it. But now I have dirty water filling my dishwasher. Over a couple days after running my dishwasher I remove 8 quarts of smelly water from the bottom of my dishwasher. The dishwasher drains completely, after finishing, but slowly fills over days of inactivity. I closed the supply valve to make sure it wasn't a leaking supply. There is high loop but I believe there is insufficient column of air above dishwasher trap to break the siphon activity. Or there is sufficient air but the air slowly is replaced by water after several dishwashing runs. I am about to connect the dishwasher drain to the disposal again to fix this problem but I won't pass an inspection in Illinois. I could add an air gap but my wife is not keen on that idea. What other changes would fix my problem?
