I need help figuring out what's causing this

Hello, this is happening with my kitchen sink. First time doing any plumbing for our kitchen remodel. If the water runs for more than 20 seconds or so, it starts to fill and won't drain. If I turn on the garbage disposal, it will drain. But, turning it off causes it to backup and splash like the video. I have it connected with a p trap. It does have a vent going to the roof. I'm assuming there's a block in the vent or something. submitted by /u/jfroosty [link] [comments]
