The p-trap traps water in its dip, sealing off the pipe.

As water flows down the drain, the water level rises and flows down the drain pipe with accompanying waste to the sewage system.

As the water stops flowing, the water balances out and new water becomes trapped again in the dip of the p-trap.  This water eliminates space for any air or gases to flow back up through the drain.

As you can see, water is the main factor that allows a p-trap to work.  If the p-trap becomes dry, then those smells can start to seep into your building.  P-traps typically only become dry at drains that are rarely used, most often floor drains.  If you begin to smell an odor from a drain, poor some water down it to fill the p-trap back up.

For the most part, waste is able to move through the P-trap pretty successfully.  The P-trap is built to create a smooth flow and there is typically enough water to create a consistent flow.  Some things can begin to build up over time however and cause a clog in the drain.  This can be remedied fairly easily through cleaning or replacing the p-trap.

So the next time youre ready to curse that stupid curved piper under your sink for taking up valuable space, remember your life would stink more (literally) without it there.
