Can P trap installed backwards?
The outlet end of the trap pipe should be lower than the inlet when installed properly. The example shown has it backward, which creates a trap seal more than 4” and makes the drain more likely to clog—and that’s a long explanation for why a backwards trap is a bad thing.

What should the vertical drop of a plumbing trap be?
The greater the velocity of the water rushing through the plumb fixture drain, the more likely the drain will siphon the trap seal. The vertical drop for sinks, lavatories, showers, and bathtubs is between 18” and 24” but not more than 24”. The shorter the vertical distance, the more efficient the trap functions. Check out the diagram in Figure #5.
