What material is typically used for water supply lines in homes?

The use of copper, PEX, or PVC for water supply lines in homes is due to their advantageous properties that make them suitable for plumbing systems.

Copper is known for its durability and resistance to corrosion, which ensures that it can withstand the pressures and temperatures found in water supply systems. It also has antimicrobial properties, making it a safe choice for drinking water.

PEX (cross-linked polyethylene) is flexible, lightweight, and resistant to scale and chlorine, which contributes to its longevity. It is easier to install than rigid piping systems since it can be snaked around corners and is less prone to leaks due to its ability to expand and contract with temperature changes.

PVC (polyvinyl chloride) is a widely used plastic material that is resistant to corrosion, lightweight, and relatively inexpensive. It is ideal for cold water supply lines and is commonly utilized in various plumbing applications.

These materials collectively contribute to efficient, safe, and long-lasting water supply systems in residential homes, which is why they are favored in plumbing installations.
