Trap

Definition

A trap is a component located at a plumbing fixture, designed to hold a quantity of water that prevents gases in the sewer system from entering a room.

Purpose

The purpose of a trap is to create a water seal that blocks sewer gases from entering living spaces, maintaining a safe and odor-free environment. This water seal prevents backflow of gases while allowing wastewater to flow through.

Examples of Use

1. Sinks: Underneath sinks, traps are installed to prevent sewer gases from rising through the drain.
2. Toilets: Toilet traps hold water in the bowl, blocking gases from the sewer system.
3. Showers: Shower drains incorporate traps to ensure that no sewer gases enter the bathroom.

Notes
