Which metal is preferred for water pipes?

When it comes to water pipes, several metals are commonly used, each with its own advantages and considerations. The most commonly preferred metal for water pipes in residential and commercial plumbing systems is copper. Here are a few reasons why copper is often the preferred choice:

1. Corrosion Resistance: Copper is highly resistant to corrosion, which helps prevent the formation of rust and ensures the longevity of the pipes.

2. Durability: Copper pipes are durable and can withstand high pressures, making them suitable for both hot and cold water supply lines.

3. Safety: Copper is a non-toxic material, and it does not release any harmful substances into the water, ensuring the water remains safe for consumption.

4. Heat Conduction: Copper has excellent thermal conductivity, which means it efficiently transfers heat. This property makes copper pipes ideal for hot water supply lines.

5. Reliability: Copper pipes have a proven track record and have been widely used in plumbing systems for many years, establishing their reliability and performance.

It's worth noting that other metals such as galvanized steel, PEX (cross-linked polyethylene), and CPVC (chlorinated polyvinyl chloride) are also used for water pipes in specific applications. However, copper is generally the preferred choice due to its combination of corrosion resistance, durability, safety, and reliability.
