After all of the wonderful advice I have received here, I'm pretty sure that the basement bathroom is not vented at all. Neither is the top-most bathroom. I can cut open the walls in the basement and upstairs bathroom to vent the lavatories, but how do I vent the existing shower in the basement? Do I have to remove the pan and run pipe from the shower p-trap? Can I run one long pipe up the inside wall to vent both bathrooms out the roof? Do I have to tie the new vent into the existing vent for the main floor bath? Any advice would be greatly appreciated!
