@PEDARRIN2, thanks a lot sir! actually I'm reading some online plumbing notes earlier and i found out that a 4" pipe needs a 1/8" slope for every 1' of horizontal run, or 0.0833mm/m (right?) I'm a bit confused about my first figure sir, because there is two(2) floor clean out in a single pipe...

@Drazen Yeah I feel trapped here. But personally I enjoy this environment with me "as of now". I found it challenging yet arrogant. This HAP software is helpful i think if I can use it correctly. And that's my problem. I don't have mentors to ask. Even sizing a simple room or office makes me...
