Couple easy questions - I'm installing a saniflo in the basement. Sink and shower to attached. Saniflo is needed because soil stack outlet is about 4' up from floor. Question about venting. I know AAV are not allowed on the vent for the saniflo -- but what about on the sink and shower?
Also - the sink drain line is only about 30" horizontal .... does it still need vented?
thanks in advance --
