P-Trap
A P-Trap is a curved pipe section that's essential in plumbing systems. It gets its name from its "P" shape when viewed from the side. This basic but important plumbing part is found under sinks, showers, and other drains. Its main job is to keep sewer gases from entering buildings by holding a small amount of water in its curved section, while also catching valuable items that might fall down the drain. All modern plumbing systems require P-Traps by building codes, making them a fundamental component that every plumber works with regularly.
