Hi All:
I'm remodeling a bathroom, raising a new wood floor over an existing slab to give me more altitude to work with to add several new fixtures over what was there before. I've pulled a permit, but did not want to annoy the inspector with what should be an obvious question... HOW to vent the corner tub?
I'm attaching a sketch and a photo showing my dry-fit fittings so far. Venting the lav, shower, and stackable washer/dryer is shown. My conundrum is how to vent the tub without a flat vent (under the plywood), since there are no walls nearby to bring-up a 1.5" vent. Because the main 2" drain drops down before tying-into the existing 3" drain, I don't think that the code would allow this long trap arm without a vent (even if I up-size the tub to a 2" drain).
Our code here is 2009 I.P.C.
Thanks a bunch!
