Hello all. I'm probably going to hire a plumber, but thought I'd give this a go in case this is actually a really easy solution.
I went from a double tub sink to a single in my kitchen. At the same time, I installed a new dishwasher, new garbage disposal, new plumbing under the sink, and an R/O. Install was pretty simple, but since doing it, I noticed that my drain fills and starts filling into the sink. Turning on the garbage disposal will briefly clear the drain and improve it, but I can still see and hear the water come back up into the disposal. I know for sure there is not a clog. The drain line has a p trap like it should and the plumbing slopes away from the drain as it should.
I believe my problem is an air venting issue. I think the double sink that was there before maybe provided enough venting that this wasn't a problem before, but now it is. Am I right? What else could be the issue if I'm wrong?
