The p-trap under your sink is one of those things that people rarely think about, but is constantly performing a vital function. What is a p-trap, you ask?
Well, since you asked… A p-trap is a curved section of the piping that runs from your sink drain into the rest of the plumbing system. The shape of this section of piping resembles the letter “P”, so, you guessed it, that’s why it’s called a p-trap. The “trap” part of the name comes from the vital function it performs. The primary function is to prevent sewer gas from traveling up into your house through your sink’s drain. This is not only helpful due to the odor of sewer gas, but these gases can also be harmful to your health. In addition, the p-trap collects a small amount of debris as water passes through it, making it a great first stop on the road to unclogging your plumbing or retrieving lost jewelry.
