Thanks for your reply. Here is what I think I will do. I will run a vent from the bathroom to the vent pipe that goes to the roof, and will tie the bar vent into this at ceiling height. I am attaching three pictures - one of the proposed bar vent, the second is the bathroom vent and the last one is the tie between both (the dark black lines are the new pipes I would put in). I would appreciate your feedback on my thoughts.
As you can see in the second picture, it would have been easier to tie the bathroom vent to the sewage pump vent. This guy at home depot thought that it would be a bad idea since it might cause a loop back for the sewer gases. Also, I do not know the specifications of the sewage pump.
