Plumbing New Bathroom - Horizontal Wet Vent

[Arca]

Hello everyone. I have been lurking here and have learned quite a bit, thank you.

I am renovating our master bedroom, starting over from a gut job.

I will be plumbing in a new tub, shower, toilet and double vanity. I have read up on wet venting and would like to share my plan with you all to critique. It is hand drawn, so I apologize if I annoy some of you.

If you guys think this is a good plan and I can move with it, I do have one final hiccup/question that I'm embarrassed to admit and can't find anything on it. I am concerned with the maximum allowable distance from trap to vent. Am I measuring from outlet weir to the main 3" drain, or from outlet weir alllll the way to the actual dry vent at the double vanity? I am in trouble if it's the later.

Thank you everyone!

The shower gets a 2" drain and p-trap and then it looks good.

Great, thanks Terry. As far as the distance from trap to vent is concerned, please tell me I measure from outlet weir to main drain and NOT all the way back to the dry vent.

It's from the 3" you're pulling from.

Great. Thank you Terry I appreciate your help.

Hey guys, need to pull this one back up.

I have tried to do my own research but would also like to check with you all.

When making my connection to the 3" trunk, am I going to want to use a wye/45 connection or a long sweep 90? This connection is critical for a wet vent, correct?

Appreciate all your help.
