According to Lowe's and Home Depot's websites, the cost of PVC pipes ranges from $0.27 to $2,000 per piece, as of October 2015. The average price of best-selling pieces is between $2.00 and $15.00. Prices significantly vary according to size, shape, and thickness.
Made from a combination of vinyl and plastic, Polyvinyl chloride (PVC) pipes are durable, long lasting, and difficult to damage. They do not wear out, rot, or rust. Because of these qualities, PVC piping is commonly used in underground wiring and water or sewer systems.
PVC pipes are available in two thicknesses: Schedule 40 and Schedule 80. While they are both made out of the same materials and use the same fittings and points of entry, Schedule 80 PVC pipe is much thicker than Schedule 40, making it heavier and more expensive. Schedule 80 is used primarily for high-pressure jobs, while Schedule 40 is less expensive and easier to install.
