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 a critical component of the plumbing system, as it helps to maintain proper drainage and prevent unpleasant odors.

The P-trap is typically made of PVC, metal, or other durable materials and is easily accessible under the sink or fixture. It's important to keep the P-trap clean and free of clogs to ensure proper drainage and prevent water backups.
