Does any one know of an aav to use with an ejector pit? Went to a customer house last night that the first plumber used one on pit. New bathroom wont drain. Seems like I remember a topic on here a while back where someone stated the is such an animal. Thanks
Nope!
2-way airflow is needed and that is not what AAV's can do...
Studor has a diagram of how to do it but the "vent" just loops back into the line above the pump discharge. Pure hackery at best but what they don't say is that will work the same regardless of using their product...:laughing:

Right on RED ... The following is not code approved, but does work.
Lets assume there is a stack with a bathroom group on the 1st or 2nd floor. Cut in a Wye in the verticle close to the basement ceiling. Then run a vent from the tank and drop it into the Wye. Think about it the drains above just pass through the Wye. The air and smell enter at the wye and are ventilated by the house venting system. Of course the discharge from the tank should enter the system downstream from the inverted vent.
I'm sure this will cause comments. But what the $hit sometimes you have to make something work. You could also vent out a sidewall but there are areas that don't allow that either, there is quite a bit of smell from a sewer tank, might be ojectable from as neighbors standpoint.
If they're legal in your area, Studor has a way to do it. They have diagrams on their website. They have you tie in to the top of a horizontal drain to get air.
They just changed the code in NJ allowing them for situations like this.
