Is P trap necessary?
A P-trap is required to be installed in most sink, shower, and bathtub drain lines by law. The reason P-traps are so essential is because they retain clean water in the drain line. This water seal stops horrible-smelling sewer gas from coming back up the drain line and into your home.

Do flexible P traps work?
P-traps take on and maintain the shape of a letter p to keep sewer gases out of your house.

Why does my P trap smell?
A p trap is designed to use water to block the sewer gases from leaking up the drain. If a sink’s p trap dies out this can result in a drain that smells bad. To alleviate this problem pour water down the drain to restore the water barrier in the p trap.
Does P trap need to be below drain?
It is not ideal to have the p-trap below the the exit drain because water gravity has to force the water out instead of it flowing downwards naturally. They both work and have seen it many times. But essentially anything below already creates its own p-trap- so using another is redundant.
