I need to replace a short (less than 5 feet) of a 3/4" hydronic copper piping loop. Can I substitute 3/4" PEX for the copper? Is there a flow-volume or any other issue?

Hello, and welcome to Stack Exchange. I'm no expert, but if this is just to save the cost of copper it doesn't seem worthwhile to me.– Daniel GriscomCommented Oct 18, 2016 at 16:06

Partly it's to get familiar w/ PEX.– MikeCommented Oct 18, 2016 at 17:08

1What fittings will you use to go from copper to PEX and back?– SeanCommented Oct 18, 2016 at 17:41

Flow shouldn't be an issue. You can check the table here for copper and here for PEX to see how much pressure you'll lose per a given length of pipe. Copper and PEX are very similar.
