Background:
Kitchen sink with two sink basins. Dishwasher hooked into garbage disposal on right side.
No issues with drains, smells, traps, etc in any other parts of the house as far as I have noticed.
We primarily get the sewer gas smell when emptying a large pot or doing a lot of dishes commonly combined with using disposal. You can sometimes hear the left sink spit up right after using disposal and that's when the smell is worst. Under just normal use the sink will sometimes make the glug glug sound when draining and sometimes not.
I'm thinking since there are two P traps the volume of water and the disposal is sucking the water out of the second trap but i'm not sure if it's plumbed wrong and should have just one trap or I have a secondary issue with the vent. There are a few vents in the back of my house but nothing above the kitchen so i'm not sure how this drain ties in. House built in '86 and none of the houses in the neighborhood have vent stacks in the front so I assume everything vents to the back so it looks better from the outside.
