Since I am redoing the plumbing, I decided to tackle the kitchen sink as well. as you can see by the picture, we have a dishwasher, a reverse osmosis drain (blue tube), a dispoal (middle sink) and two sinks. It gets clogged every other day or so. I am assuming this is because there is no vent. Under the floor it runs 9 feet and has elbowed into a back tee 1.5 X 3 in a horizontal 3 coming from the bathroom.
I'm going to put it into a back wye 1.5 X 3
My question is, should I redo the whole thing? or can I just put in an AAV vent under the sink?
