Moreover, how do you loosen P trap?

Unscrew the nuts holding a plastic P-trap by hand, gripping the trap firmly with one hand and rotating each nut counterclockwise. You must unscrew two nuts to remove the trap. One holds the trap to the tailpiece, the small length of pipe extending down from the sink, and the other holds the trap to the drain line.

Secondly, how far below drain should P trap be? According to the International Residential Code, the maximum vertical distance between the sink drain and the entrance to the p-trap is 24 inches.

Also question is, what is the difference between a J bend and a P trap?

The J-bend beneath the sink is also referred to as the P-trap, the U-bend and sometimes even just the drain trap. While there are some subtle differences between each of these fittings, they all essentially mean the exact same pipe in a drain pipe system.

Does P trap have to be directly below drain?

The "P" trap SHOULD be directly under the drain, but no more than a few inches off center of it, if conditions require it.
