2007 florida code says no but there are a couple guys at the shop saying you can use like a 3x2 santee on it's back with the 2 inch vertical to catch a vent. I'm trying to prove them wrong. I'm saying you have to use a combo. Agree or disagree with me?

706.3.....why would they argue....Florida has wet venting...why would code risk the issue...

That is a common misconception around here.

A sanitary tee is a "short radius fitting". Short radius fittings are allowed in individual fixture drains, but not allowed in the building drain, or a drain serving more than one fixture.

But, you would still have to argue till doomsday with an inspector if you did it. They don't know the code...........................

you cant put a tee on its back

Hate to break this to you fellas but under the IPC you can indeed lay a san tee on it's back provided the outlet is vertical ( or 45 degrees ) and that it is dry. ( operative word here is dry ) Problem is, you guys are all looking at the prohibited use of fittings in the DRAINAGE section of the code. The san tee is not drainage, it's vent. Unless specifically prohibited by ammendment you can most certainly do it. Some advice. Stop reading the code with an eye out for what you can't do and start reading it with an eye toward what you can do.

Table 706.3 is for drainage fittings.

Our local plumbing inspectors would turn it down instantly. And I'll agree with the post(s) that stipulate that inspectors do not know code. I would not do it based on the fact that if the vent were to be converted into a waste stack in the future (a lavatory, sink orwater cooler), the 3x2 san tee would then not be code compliant. But I'll also agree if the fitting is considered a vent fitting only, the code could be interpreted to allow for it.

If your local inspectors would turn it down then they need to be educated. As far as it eventually being turned into a waste stack, that argument don't fly either. Any plumber or inspector with 1/2 a brain would not allow it without changing it. It's not our responisbility to make sure that plumbing can accommodate any future change. Look at section 9 of the IPC. Read it thouroughly. You will not find any prohibited use of fittings. Only prohibited methods of installation. Again, everyone reads section 7 under drainage and automatically thinks that the chapter applies to vents. It doesn't. If it did then why bother to separate the chapters.

Whats the advantage of using a san tee on its back within 6" below the flood level rim of the fixture it serves?

Dont want to start a fracus today......his statement said a 3x2 on its back with the 2" vertical to catch a vent. This implies it is a drainage fitting, otherwise he'd say on a vent system......incorrect answer and analysis on your part.
