What are uPVC pipes?
PVC pipe is a rigid plastic pipe made from polyvinyl chloride. Most pipe sold as PVC is uPVC, meaning it has no softening additives, so it stays stiff and strong.
PVC pipe comes in drainage grades and pressure grades. Drainage pipe carries waste and rainwater by gravity, while pressure pipe carries water under pump or mains pressure. Joints are made with solvent cement or rubber ring sockets.
