I'd like to install a water softener in my basement, and have a good spot with electric and supply line access, my only issue is the drain. There's direct access to a vertical stack coming from a bathroom sink that I'd like to use. It looks like this stack doesn't have a direct run to the roof, and is using an AAV instead for venting.
Thoughts on using a sanitation Y to tie in, create a P-trap off the Y, and draining directly into the P trap with a 2" air gap?
