I have just installed a sewage ejector pit and the inspector told me that I cannot vent an ejector pit with an AAV. Now I am trying to decide the best/easiest way to vent it through the roof. I live in Denver, CO.

Option 1: The easiest option seems to be running the vent 10 feet to the nearest exterior wall and running it up along the outside of the house.

Option 2: Try to run it inside the interior wall next to the ejector pit. The problem here would be getting it through the lathe and plaster wall on our main floor. In addition this is a load bearing wall in the basement so I would like to jog around it in the floor joist above so I wouldn't have to cut such a big hole into the load bearing wall.

The questions I have are:
1.) Which method would you recommend? Do you foresee any issues with either method?

2.) 2" ABS is the current vent material. Is it OK to use the same all the way through the roof?

3.) Should I tie into the main 5" cast iron vent in the attic or put a new hole through the roof for the 2" vent?

4.) If running it up the exterior of the house does it need to go into the attic or can it vent right through the soffit and roof at the edge of the house? (or does it need to be higher up on the roof)
