Which pipe material is typically used for hot water distribution?

CPVC, or Chlorinated Polyvinyl Chloride, is the correct choice for hot water distribution systems. This material is specifically designed to handle higher temperatures compared to standard PVC, which can become deformed or damaged when exposed to hot water. CPVC pipes can withstand temperatures up to about 200°F (93°C), making them ideal for transporting hot water in residential and commercial plumbing applications.

Furthermore, CPVC is resistant to corrosion and doesn’t suffer the same issues as metal pipes, like galvanized steel or cast iron, which can corrode over time when exposed to hot water. Cast iron and galvanized steel are typically used for other applications due to their strength and durability but are not ideal for hot water transport because of their tendency to rust and corrode. PVC, while a versatile option for cold water, cannot withstand the high temperatures needed for hot water systems. This is why CPVC emerges as the preferred choice for reliable and effective hot water distribution in plumbing systems.
