What is the function of a P-trap in a plumbing system?
Correct Incorrect A P-trap is a U-shaped pipe located beneath sinks and other fixtures, holding a small amount of water to form a seal that blocks sewer gases from re-entering the home. This essential component helps maintain indoor air quality and prevents unpleasant odors. Additionally, the P-trap can catch small objects that may fall into the drain, offering a chance for retrieval.
