We've lived in our house little over a year and the kitchen sink is a pain in the butt.
When you are running water and washing dishes and such all is fine. Wash a large pot of some sort and dump the water into the sink all at once and the draining slows to a trickle and you have to push your finger or a utensil into the disposers rubber guard to break the vacuum and get it draining fast. When you do that you get some bubbles and off the water goes nice and fast so the drain itself seems fine.
It had this problem since we moved in, and it continued after I put the disposer in. I figured it wasn't vented properly, so today I cut a hole in the drywall expecting to put in an air admittance valve (no room under the sink) only to find it vented already.
Headed to the roof to look for a clogged vent, other than a leaf or two all looked fine. I poured a gallon pitcher of water down the vent from the roof and my wife heard it rush down into the kitchen pipes and out.
So now I'm really stumped and I hope someone has an idea where I should look next.
Other things, that might help. The house is from 1964 and the kitchen was renovated last in the 1990's. The kitchen waste pipes are PVC but the vent transitions to brass somewhere before the attic. I'm confident the sink is not in the original location. Dishwasher drains into the disposer, and never has an issue. Single sink bowl. I don't see anything in the attic piping that would be a place where water could pool in the vent and block it.

there is nothing wrong
the disposer's 'splash guard' is operating properly
this is a common issue with ANY disposer as the path of water is through the splash guard, into the grind chamber, sideways through the slots then down a bent tube into (sometimes) a baffle tee
removal of the splash guard may, or may not, result in back splashing when using the disposer
just use the other side of the sink (if available), or remove the offending disposer

When you dump a lot of water into the sink, all at once, it causes the air in the disposer to create a bubble which prevents the water from draining. When you push down on the baffle, it lets the air out so it can drain properly. If you run the disposer, it will suck the air out and do the same thing, namely drain properly.
