The theory goes that a copper pipe will split if it freezes and a PEX pipe will expand, but is this true? Matt Risinger discusses the different effects frozen water can have on our most commonly used pipes, and tests each out for you to see. He fills up copper, PEX, and Sharkbite pipes with water, and then freezes them for 20 hours. [Spoiler Alert] Turns out the copper pipes split just as expected, and the Sharkbite tops couldn't stand the pressure. However, the CPVC and PEX had what it takes to withstand the cold. Dive into the video to learn more about how to choose the right pipes to combat the winter weather and its effect on your pipes.
