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 places requires an air gap but previous DW did not have an air gap.
The dishwasher drains into the disposal. At times my wife has complained of foul odor in the dishwasher . The only way I can see sewer odor entering the dishwasher is if the disposal p-trap is dry so I've instructed her to run a little water into the disposal sink side after using the disposal.
A couple of questions
1- can disposal p-trap get pumped dry with the disposal running?
2- would there be a benefit to install an gap as I think this may be current code here. that would require boring a hole in the granite top which I prefer not to do if not required.
