Venting basement washroom???
 

Hi,.
I'm installing a Saniflow pumping toilet in the basement of my two storey home. I will also be connecting a bath tub and vanity sink to this pumping toilet. Can I vent this system through a vent connected to a vanity sink on the first floor?? I would be connecting to the vent at a level above the first floor sink's trap.


Thanks

You need to check your area Code for vent sizing. Since you are in Canada, I am not knowledgeable of your codes.
