What Is Plumbing Trap?

A plumbing trap is a common device made by bending a pipe. The job of this trap is to prevent sewage gas and bad odors from entering the house. It also prevents insects, worms, cockroaches, and mice from entering the house. It can also be called a pipe trap or drain trap.

A plumbing trap is usually a curved portion of a drain pipe made of metal or PVC that looks like a U. It is mainly found under the sewers.

It is located in the sewers under the shower or bathtub in your home. If you open the cabinets under your kitchen sink or bathroom sink, you will see curved parts that may be some kind of plumbing trap. The bend of the plumbing trap retains water which blocks the sewer gas.
