Bathroom DWV question

[spidey417]

Hi, first time poster!

I've learned alot about plumbing here about using proper fittings such as long sweep elbows and combo wye's.

I've attached a diagram of the two bathrooms I'm remodeling at my home and wanted to know if the Master WC and Hallway Tubs are considered wet vented here. (see layout and DWV diagram).

Any help and advice is greatly appreciated!

Your tthree main problems are that the tub needs a vent, the drain from the kitchen has to be 2", as does the drain for the two lavatories.

HJ - Can ask you one more question? Can I use a 3" x 2" double combo tee wye on top of the soil stack? Or should i use a 3" x 2" double sanitary tee or double fixture tee?
