Types of plumbing pipes mainly include PVC, CPVC, and UPVC, which are widely used in residential and commercial water systems. PVC pipes are lightweight, cost-effective, and mainly used for drainage and cold water supply. CPVC pipes are designed to handle both hot and cold water due to higher temperature resistance. UPVC pipes are rigid, corrosion-resistant, and ideal for drinking water supply and drainage systems. Selecting the right pipe depends on water temperature, pressure, and durability requirements.
