An Introduction To 40mm Waste Trap


A 40mm waste trap is a plumbing component designed to prevent sewer gases from entering a building. Typically installed under sinks, showers, and other drainage points, it holds a small amount of water that acts as a seal, blocking the gas. The '40mm' refers to the diameter of the pipe, which is a standard size in many underground drainage products. 


These traps are characterised by their 40mm diameter, making them suitable for a variety of plumbing fixtures like sinks, baths, and showers. They are one of the most well-known water pipe systems commonly used in plumbing. The design of a 40mm waste trap includes a curved section of pipe that holds water, creating a seal. This water seal is crucial as it blocks the backflow of unpleasant and potentially harmful sewer gases into buildings. The 40mm size is particularly significant as it corresponds to a common pipe size in plumbing systems, ensuring compatibility and ease of installation in many scenarios.
