From IRC saying not allowed: Each fixture drain shall connect horizontally to the horizontal branch being wet vented or shall have a dry vent.

Can you give a reference, year number and section number? Because I can't find that text in any version of the IPC from 2006 to 2021.From IPC saying not allowed: Each fixture drain shall connect horizontally to the horizontal branch being wet vented or shall have a dry vent.
Do you have a link for that in IPC?From IPC saying not allowed: Each fixture drain shall connect horizontally to the horizontal branch being wet vented or shall have a dry vent.

OK, but that link and that section don't have the words you quoted.912.1 of 2015 IPC: https://up.codes/viewer/alabama/ipc-2015/chapter/9/vents#912
I find 912.2.1 Horizontal Wet Vent912.1 of 2015 IPC: https://up.codes/viewer/alabama/ipc-2015/chapter/9/vents#912
Go to International code counsel website and type in the search bar " Bob scott plumbing venting: decoding chapter 9 of the IPC". His book shows a picture of that very thing that is not allowed. You have to own the book to see it. The picture was to large to upload. Try to find a diagram online of a wet vent that shows a toilet entering vertically. It would be similar to a drain entering a wet vent vertically. I am not bothered either way if anyone disagrees with this I am just trying to be helpful.[/QUOTE
Thanks James very much appreciate trying to be helpful. wont purchase the book because its the wrong code for me. Im unable to see his view explaining the code but havent seen anything prohibiting it. trying to understand it. Im a little stubborn Ive been burned so many times beliving blindly others that were wrong. I must see it in the code. no matter how much of an Einstien it is if it aint in the book it aint true. . What matters most to me is UPC. any way thanks to all as well
You are correct. I got lost jumping between versions. IRC only.OK, but that link and that section don't have the words you quoted.

Hmm, so it is in 2018 IRC P3108.1. I wonder why the IRC and the IPC diverge like that, and if it is really intentional.
So does the IPC. It's the UPC that restricts it to one bathroom group.Another divergence is that P3108.1 allows wet venting two bathroom groups with horizontal wet venting.
Yes thats all true . nothing to do with all drains coming in horizontal on a wet vent I dont think? but its a possible arguement for allowing the toilet to dump verticaly into the horizontal drain.The trap weir on a shower and bathtub will always be below the wet vent opening and the trap weir on a toilet will always be above the floor even if the drain connects horizontally to the wet vent........ Back to the drawing board.
Yes. After I reread my statement I realized I must be confused or tired or both. I'm reminded of the saying, " baffle them with bull####".Yes thats all true . nothing to do with all drains coming in horizontal on a wet vent I dont think? but its a possible arguement for allowing the toilet to dump verticaly into the horizontal drain.
While not explicit, horizontally wet vented fixtures under UPC 908.2 are clearly exempt from 905.2. With a horizontally wet vented fixture, the invert of the vent connection is the invert of the drainage piping, so it would be impossible to comply to 905.2 and have wet venting. 908.2.1 tells you that the dry vent connection to a horizontal wet vent has to comply to 905.2; the implication is that the wet vent connections do not.Section 905.2 allows venting to be installed in a horizontal position. However, the invert of the vent connection must be above the centerline of the drainage piping to which it is connected. The objective of this code is to keep the vent opening above the flow of effluent. The way you have drawn it is not code compliant. (UPC)
This is awkward, but...
