I am in the planning phase of a large remodel on my house and need some help on how to route some DWV lines. As a DIY’er with little plumbing experience, I am tryinng to keep the system as simple as possible. The two bathrooms are both on the first floor and share a non-load-bearing wall that I was hoping to dedicate to the plumbing. It seemed that the easiest way to do it would be place the toilets directly opposite each other and have the soil/vent stack be in the wall between them. The first floor sits over a shallow crawl space, and the stack would still be 8 or 10 feet from where the sewer drain exits the house. My concern is that I don’t have enough height to have the toilets enter the stack at seperate heights. I am curious if a double tee exists in a size for toilets (3 or 4 in., right?), and is this a good way to solve this problem.
Let me know if more details or a floor plan would help. I just gut a scanner and could probably figure out how to scan in some sketches.
Thanks in advance!

A cross is what you mean I think..and I have seen them in 3'' and 4''..whether it is ok or not..hmmm, maybe a plumber knows if it is a local call or not, I don't see why it can't be done.
The proper fitting fitting is not a double sanitary "T". It will have 3" on the bottom two 3" outlets and a 2" or 3" on top. When you look thru the two ends, you cannot see thru it.

Scroll part way down and look for a 'double wye'. A little further down is a 'double combination wye & 1/8 bend'. I think you want one of these. They're cast iron and I doubt you'll find anything like it in ABS or PVC, although a good plumbing house might have something.
Just below the double wye & 1/8 is a 'sanitary cross'. I think that's a vent fitting and not a drainage fitting, but I'm not sure. What's to stop waste from one side going up the other?!
I've never been too good at figuring out the exact fittings I need before I start. I just go in the crawl space with a big box of parts and start fitting them together. When I'm done at least half of them are left.
Don' forget to put a test wye in your line right before it joins the main.
yes they make a double T. I got one in the shed. And it is not cheap. here a picture of one in a wall. It could be use underground too, just add a sewer 90 on bottom.
Thanks everyone! I'll head to a plumbing supply store and look for one. I'm an hour from the closest one, so I was trying to avoid a 2hr. wild-goose-chase. Now that I know it exists, I don't mind the drive.

i bought a double wye at lowes and h d had them also in pvc, i think they was about 23.00 each.thats what i think you'll need to use as a double sant. could flow from one side to another.
