Venting a Basement Bathroom
I have spent quite a bit of time reading the Ontario Building code as well as looking at a number of sites and finally decided the right thing to do was to ask here.
I am putting in a basement bathroom and the venting is a real pain. For a matter of scale, the bathroom is about 9' x 7' with the 9' dimension measuring from the WC down to the Soil Stack.
My question is, will the diagram as attached be acceptable and if so, would I be okay if I removed the 1 1/2" vent and ran the whole thing off the 2" vent.
