Howdy!!
I've exhausted all other options for venting our basement bathroom group and will need to install an AAV. Below is a photo of the rough-in plumbing. I need to move the toilet back about 6 inches before installing the flange, and also re-route the drain line for the lav.
My question is; Can I install 1 AAV in the lav cabinet as pictured? OR, do I need to tie into or also vent the tub since it connects after the sink/lav?
