vent pipe opening from soil or waste pipe, except that of water closets and similar fixtures, shall not be below the weir of the trap.

something to that effect, I am sure water drains the same here as it does in florida.

If you can plumb to the UPC, you can plumb anywhere.

It will work fine unless the arm fills up......if the arm fills up the trap will siphon with a combo. Looks like the code is letting you use whatever fitting you want unless you install it upside down. whats the point of a code book anymore. next they will be letting people lay tee's down on their backs or quit making them all together and just have combos

Ah but that's just it, the waste arm won't fill up because it's just a tad bit bigger than the trap it's serving. The water only occupies the bottom section of the pipe. The air is able to exchange with the water and break the siphon because of the air channel in the top of the pipe. As long as the waste arm is properly sized it will work perfectly. If the pipe is too small then there is not enough room for a good sized air channel then it WILL siphon the trap. Not rocket science.

How is that any different than wet venting a kitchen?

Well sure they are allowed in the vent system...I'm talkin drain

And sanitary tees are not obsolete. Allot of times you won't have enough room to oversize the pipe so you would have to do it the conventional way and use the minimum waste arm size with a san tee.

It can be convenient though to use a combo in situations that would make cleaning the line difficult with a san tee. The first example that comes to mind is a twin lav setup. A double combo works great in that situation and makes for an easy drain cleaning call later on.

I'm talking about tee on it's back to serve as the vent for said fixture, instead of useing a combo we can use a tee, most codes do not allow this setup, does yours?
