Common Plumbing Pipe Types and Where They Are Used

Plumbing pipes come in different materials, and each type has its own common uses, benefits, and concerns. The pipes in your home may depend on the age of the property, local codes, water quality, and past repairs or upgrades.

Understanding common pipe types can help homeowners recognize when a repair or replacement may be needed.

Copper Pipes

Copper has been used in plumbing for many years. It is durable, handles heat well, and is often used for water supply lines. However, copper can be more expensive than some newer materials, and corrosion may occur in certain water conditions.

PEX Pipes

PEX is a flexible plastic piping material commonly used for water supply lines. It is popular because it is easier to install in many situations and can be routed through tight spaces. PEX is often used in newer plumbing installations and repiping projects.

CPVC Pipes

CPVC is a plastic pipe material designed for hot and cold water lines. It is more rigid than PEX and has been used in many residential plumbing systems. Like any material, proper installation is important for long-term reliability.

PVC Pipes

PVC is commonly used for drain, waste, and vent lines. It is not typically used for hot water supply lines. PVC is lightweight, resistant to corrosion, and commonly found in drainage systems.

Cast Iron and Galvanized Pipes

Older homes may have cast iron drain lines or galvanized steel water lines. These materials can last a long time, but they may corrode, rust, clog, or deteriorate with age.
