Hi all,
First post here, so be gentle.
I am installing a half bathroom in the basement of my 60 year old house. My problem is I have no vent (other than the 4" main stack vent) in the basement that I can access. I cant access the upper portion of the stack vent in the attic to run a new vent down to the basement, as it is all enclosed and it would be a nightmare to cut a new hole in the roof and run a vent to the basement.
Attached is what I am proposing to do in red. Basically, I want to use the main vent stack, as the vent for the basement bathroom sink, even though the 1st floor bathroom uses this part of the pipe to dispose of waste.
Will this work? If not, why.
Thanks for any help guys.
