Let me try to put my question in simple terms, because it's kind of convoluted and I can't post a sketch at the moment.
Basically, is there any restriction against running a 2" kitchen sink drain line horizontally about 6 inches above the floor?
The drain inlet will be set at a conventional height, where it will be vented immediately (sani-tee), drop vertically to a long sweep 90, and travel about 4 feet (6" above the floor) where it joins another vertical drain line, which it will connect to via a combo wye.
(Edit) ...and since I have to connect to the vertical stack at such a low height, is it OK to place the cleanout above my combo wye, rather than below it? I'm anticipating having to put a second cleanout under the drain inlet under the sink. I do have another cleanout on this particular line on the floor below.
