There are differences in the material of hot and cold water pipes. In general, the cold water pipe is mainly made of PVC, its advantages are corrosion resistance, not easy to aging, waterproof performance; while the hot water pipe is generally made of PP-R, which has high temperature resistance, high pressure, high strength and other advantages.
Second, the color is different
Cold water pipe and hot water pipe color differences also exist. Cold water pipe is often blue or green, this is to allow users to distinguish the location of the cold water pipe, so as not to be confused with the hot water pipe. The hot water pipe is red or orange, easy to distinguish.
