The "tee" that I assume is the vent for the shower needs to be a wye not a santee. I also assume that the wye downstream of the toilet is the toilet vent? You need to tie the waste for the shower downstream of the toilet and toilet vent, the vent invert should be higher than the center line of the 3" main.

If the vent is coming off at a nominally vertical angle and it's NOT a wet vent then using a sanitary tee is just fine.
Also if your application allows it you can ditch the vent AFTER the toilet and wet vent the toilet through the sink line.
If that wye AFTER the toilet is picking up more waste then that line would need to be separately vented as you're not allowed to wet vent past a toilet.

I guess you need to figure out what code you're under because different codes require different things. I'm not sure what code Oklahoma uses. You can use the lav waste as the wet vent for the toilet but you need to tie the lav waste (vent for toilet) centerline or above the 3" main and then tie in the shower waste and vent downstream of the toilet and wet vent. As for the vent for the shower, the code I'm under says you can't use a Santee on it's back under the flood level rim of the fixture.

I am pretty sure no code will allow you to use santees (even long bend ones) on their side like you are attempting to do. Your vent for the shower trap looks fine, but whatever you are trying to do before the toilet needs to be vented separately as well. I like that you are adding the cleanout.

This is Canadian code but...
2.2.4.2 Sanitary T Fittings
1. A single or double sanitary T fitting shall not be used in a nominally horizontal soil-or-waste pipe, except a single sanitary T may be used to connect a vent pipe.
And no he is more then able to wet vent the toilet through the shower like he is (as long as the connection DOWNSTREAM of the toilet is separately vented). This would be 100% acceptable in Canadian code anyway and I find our codes are not much different on things like this.

This would be correct here and unless I'm missing something it would be correct with IPC also.

venting
The order of the various connections is immaterial since they are all active drains. As such, they can also enter the main line on a plane with the centerline, they do not have to "rolled" up. Rolling the vents up only applies to "dry vents" which can accumulate material with no water flow through them to wash them out.

Well keydash,
it looks like you've got your work cut out for you. Lots of different views from lots of different codes. It's best to find out what code your under and follow those guidelines. Good luck!

Looks like it's IPC based in OK.

We're under the UPC. I think the same about the other codes.

codes
YOU only think they are "goofy" because you must not like them. The users of the IPC thought the same thing about the UPC when they rejected the agreed upon merged code. They did not like the idea of having to give up some of their cherished, "not goofy" (to them), traditions.

I only think they're goofy because I was not trained on the IPC or the other codes just like I'm sure some of the code requirements by the UPC sound very strict to people in the IPC. The IPC is alot more forgiving when it comes to wet vents and vertical offsets in trap arms which I've never seen, let alone been allowed to do. The UPC doesn't allow 2 traps on 1 trap arm. The picture that shows the shower, shower trap arm and vent upstream of the toilet, toilet trap arm and wet vent would not be allowed. The shower would have to tie in downstream of the toilet trap arm after the vent. The UPC also considers a wet vent to be a vent and therefore needs to tie in above centerline of the toilet trap arm. As for santees, below the flood level rim they are considered the same as 1/4 bends and need to be installed the same as any drainage fitting, so they'd never be allowed on their backs or horizontal to horizontal. The only reason the IPC and UPC haven't merged is simply the cost to people who have to learn a new code.
