Gotcha! So you would still just recommend the standard double sanitary tee then?

Yes, but I want you to know that the best way to pipe this, BY CODE, is the way I drew it up at post#9. This will work just fine, but may not be approved by all codes, OK?

Mark - One last follow up question. From your response, it sounds like a double sanitary tee is not code.

However, if I use a similar one called a "Double Fixture", would that work? Or is that still not code either?

That fitting is better than a double wye fitting, but unfortunately I can't speak to code in your area... can just make generalizations.

If you want to do this by code that is accepted everywhere, you really need to follow the drawing I posted at post #9.
