“A polypropylene trap in pipework refers to a type of plumbing fixture used to prevent the entry of foul-smelling sewer gases into living or working spaces. The trap is an essential component in plumbing systems, typically installed beneath sinks, basins, showers, and other fixtures that have a drain outlet.
The purpose of the trap is to create a water seal that prevents sewer gases from rising up through the pipes and into the building. It works by holding a small amount of water in a U-shaped bend, creating a barrier that blocks the passage of gases while still allowing wastewater to flow freely.
Polypropylene is a type of plastic that is commonly used to manufacture plumbing components, including traps. Polypropylene traps are favoured for their durability, resistance to chemical corrosion, and ease of installation. They are a popular choice for both residential and commercial plumbing applications.
Regular maintenance of these traps is essential to ensure they continue to function properly. Over time, debris and sediment can accumulate in the trap, potentially reducing the effectiveness of the water seal. Cleaning the trap periodically helps maintain the water seal and prevents any foul odors from entering the building.”
