A drain trap, also known as a P-trap, is a curved pipe that traps a small amount of water, which prevents sewer gases and odors from entering your bathroom. The trap is connected to the drain pipe under the sink, and its primary function is to create a sealed system to prevent gases and odors from rising up into the bathroom. The water in the trap acts as a barrier, keeping unpleasant odors and gases from entering the space.

In addition to preventing unpleasant odors, drain traps also help to eliminate the risk of health hazards. Without a trap, sewer gases can rise up into the bathroom and cause health problems. The water in the trap also helps to reduce the risk of backflow, which can contaminate your water supply with sewage and other contaminants.
