Currently finishing my basement and am now working on the bathroom. I'm installing a Saniflo macerating unit with a toilet, shower and sink flowing to it. I DO NOT have any pre-plumbed venting. Obviously I'm below grade (single family ranch) and cannot access my existing plumbing vent stacks. What are my options to vent these items to the outside? If I vent them out the side of my house, will they smell?
