I'm doing a complete remodel of my kitchen. Part of that has a new island for the kitchen sink and dishwasher. I've googled loop vents and Air Admittance Valves (AAV) till I think I understand how they work. I like the idea of a loop vent because there's nothing to go wrong and it's silent in operation, but the venting in my unfinished basement leaves me with a question. There are 2 drains vent connected to the horizontal run of the existing the dry vent before it goes vertical to the roof. Is the drain/venting plan I've drawn in green and blue in the picture OK?
