Is there a reason why the IDs for PEX tubing are somewhat smaller than for copper? In other words, why is the ID of (for example) a 1/2-inch PEX tube smaller than for 1/2-inch copper?
Do they make PEX smaller on purpose? Is there an advantage to it being smaller? I have always thought of it as an inconvenience because it creates problems in certain situations (for example, when plumbing a tub spout, you can't use PEX because it's too narrow).
I've just always been curious if there is a reason for the PEX's smaller IDs (and, by extension, lower GPM rates).
