SWR pipes, which stand for Soil, Waste, and Rainwater pipes, are a crucial component in building drainage systems. These pipes are specifically designed to efficiently transport wastewater, soil, and rainwater from buildings to appropriate disposal points. Typically made from high-quality UPVC (unplasticized polyvinyl chloride), SWR pipes are known for their durability, corrosion resistance, and ability to withstand the chemical elements present in wastewater. They come with various fittings and joints, allowing for a seamless and secure installation. SWR systems play a vital role in maintaining hygiene and preventing waterlogging around structures, making them integral to modern plumbing infrastructure for residential, commercial, and industrial buildings.
