Finally starting on plumbing and have a question on toilet venting.
The existing toilet and tub in a main floor bath are both wet vented. The toilet sits right on top of a 4" cast soil pipe and the tub from a black iron pipe to an ABS 90' (no ptrap) then a run of about 3'. (which rises about 4" in the 3' /facepalm) All the tub drain is 2".
There's no vent for either of these. The cast iron soil pipe runs to the sewer underneath the slab in the basement.
So...question 1.
Assuming I replace at least part of the cast iron soil pipe with 3" ABS and 3" abs for the toilet is it ok to continue to wet vent? The run will be very short (less than a foot).
Next is the tub. Since there's no vent option I'll have to go with a wet vent again. If I go with 2" ABS for the tub and a run of the downward portion to a ptrap then then 2" to the 3" soil pipe is that sufficient?
Hope this makes sense. I *think* this will all work but not sure on what code says for wet venting.
Thanks
