What is P-trap

Plumbing

The answer to 'what is P-trap' is a U-shaped pipe installed under a sink or other plumbing fixture. The P-trap is designed to hold a small amount of water, creating a seal that prevents sewer gases from entering the home. This water seal is an important part of the plumbing system, as it helps to keep odors and pests out of the home.

P-traps are typically made of PVC, ABS, or metal, and are installed between the sink drain and the main drain line. They are an essential component of any properly functioning plumbing system, and should be checked regularly for clogs or leaks.
