Which PEX color is typically used for hot water supply?

Explanation:
Color coding is used on PEX to identify water temperature easily. Red is the conventional color for hot water, while blue indicates cold water. White or gray PEX is usually used when no temperature-specific color is applied. Using red for the hot water line makes it instantly clear which path carries heated water, reducing mix-ups during installation and maintenance and aligning with common plumbing practices. Therefore, red is typically used for hot water supply.
