The answer to 'difference between PEX pipe and copper pipe' is that PEX (cross-linked polyethylene) and copper are two of the most common types of plumbing pipes used in homes today. PEX is a flexible, plastic-based pipe that is less expensive and easier to install than rigid copper pipes. Copper pipes are made from metal and are known for their durability and resistance to high temperatures, but they can be more costly and require more specialized installation.
PEX pipes are becoming increasingly popular due to their benefits, such as resistance to corrosion, freeze-thaw cycles, and mineral buildup. They are also quieter and more flexible, making them easier to route through walls and around obstacles. Copper pipes, on the other hand, are highly resistant to leaks and can last for decades with proper maintenance. They are often preferred in applications that require high heat resistance, such as near water heaters.
