Which type of pipe is generally used for water supply in most residential applications?

Copper pipe is generally used for water supply in most residential applications due to its durability, resistance to corrosion, and ability to handle high water temperatures and pressures. Copper has been a trusted choice for many years, providing a reliable option for both hot and cold water systems. Its natural antimicrobial properties also help to keep drinking water safe and clean. Additionally, copper pipes are known for their long lifespan, which can exceed 50 years, making them a cost-effective choice over time.

While other types of pipes are used in specific applications, copper’s unique characteristics make it the preferred material for residential water supply lines. PVC pipe, for example, is often used for drainage systems and waste lines but is not suitable for hot water applications. Steel pipe is heavier and more expensive, and while it may be used for certain industrial applications, it is less common in residential plumbing. Rubber pipe, on the other hand, is not typically used for plumbing at all, as its flexibility does not provide the structural integrity needed for water supply lines.
