Our SWR (Soil, Waste & Rainwater) Piping System handles wastewater and rainwater for homes, businesses, and industrial buildings. We use lead-free materials, so it’s safer for everyone and better for the environment. The inside of each pipe is super smooth, which keeps things moving and helps prevent clogs from building up. These pipes can be buried underground and won’t rust or wear out from sewer gases or harsh chemicals.The KWIK-sil rubber ring push-fit system makes installation simple and gives you watertight joints that hold strong, even under a lot of pressure. That means you don’t have to worry about leaks or regular repairs. Whether you're using it for soil discharge, waste removal, ventilation, or draining rainwater, this system just works smoothly and reliably, year after year.
