Have you ever looked under the kitchen or bathroom sink, or looked closely at the base of your toilet? If so, you’ve probably seen a p-trap. A p-trap is a bend that is specifically placed between the vertical and horizontal connections in your plumbing system, typically very close to drains.

This commonly overlooked element plays a very important role in your plumbing. Its’ primary purpose is to keep sewer gasses from coming up into the air through your sink or toilet. It also prevents clogs from happening further down your plumbing. And, as a bonus, it can help you retrieve objects that were accidentally dropped down your drain if you check it in time. As with every part of your home, it should be cleaned and maintained from time to time to ensure that it’s in proper working order. This is a fairly simple process, and there are plenty of “how-to” guides on the internet to take advantage of.
