odor control...is not your problem....it would work for that...but venting into your sewage pipe...is a terrible idea...you will be getting bacteria into your room..not to mention a sewage back up...or flood...you would be better off going negative pressure through a organic filter.....just the gasses in the pipe building up in your space could be terrible...there is no way this would work corecctly...just go under negative pressure with filter...or use your dryer vent... ecoli sux ass..
