I am a non beleiver, I would want to know the language in the code, out here we see these things with an elbow down, we also see them connected to the floor drain below the level of the floor and I have seen one hooked to the overflow in the back of a bathtub. This has to do with air venting behind water, so I suspect if the rest of the screen is open to the air, the trap will not syphin empty problem solved. There has to be more to the rule than just a distance above.
