The function of a plumbing trap is primarily to prevent sewer gases from entering the building. Traps are designed to hold a small amount of water, creating a barrier that stops hazardous gases and odors from the sewage system from escaping into living spaces. This water seal is crucial in maintaining indoor air quality and ensuring safety within the building.

Traps are typically located in drains for sinks, showers, and toilets, and they work effectively as long as the trap retains enough water to create this seal. The design of traps is such that they also allow wastewater to flow through without obstruction, ensuring proper drainage while serving their primary function of blocking gas.

While filtration and drainage speed can be factors related to overall plumbing system function, they are not the primary purposes of a plumbing trap. The prevention of sewer gases is a vital aspect of plumbing safety and hygiene, emphasizing the importance of traps in the plumbing system.
