There is a major difference in installation. You don't glue HDPE. You "weld" it together. That also makes it stronger. There is a special machine that heats or semi-melts both ends of the pipe then pushes the ends together. Once cooled the weld is stronger than a convention glued connection. When they start welding pipes together I will snap a picture to show you more.
