well the air grill isn't going to be option in the washroom wall either...Red_Army wrote: ↑Nov 13th, 2019 10:34 pmTo pass code without practical access to a proper vent, the only way would be to install an AAV in the wall and extend it higher than the flood level rim of the sink, and have an air access grille
Me personally, I’d favour the drawing that you posted as opposed to an AAV. I’m not a fan of AAV’s
so it's either AAV under the cabinet...
or my drawing.
I prefer my drawing vs the AAV as well...
but in my example...if I was to start the vent at 26"....do I need to be up a minimum of 24" for the height of the vent?
also as @MrFrugal1 mentioned....I guess it is better to use a wye instead of the Tee?
