Hello everybody I have a question regarding a wet venting a toilet with a vanity drain. I would like to know which option is better in the attached sketch option a or option b for going vertical to horizontal. I can not put a long sweep 90 as I have a structural timber in the way. Would putting 2 45 fittings and keeping a wye horizontal be better or tilting wye at 30 degrees and using 60 degree fitting for vanity drain. I hope that is ok if vanity is wet venting a toilet.

Either option is allowed. I think I'd choose Option A, because last time I checked, a 60 degree bend in plastic has the same radius as a quarter bend, not the larger radius of the a LT90 or a 45. So while I believe they are allowed for vertical to horizontal transitions, I don't understand why.

P.S. If you use a single wye and a 60 degree fitting, the wye gets rolled 45 degrees above horizontal, halfway to upright. If you use a combo and a 60 degree fitting, then the combo gets rolled only 30 degrees.
