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 Griscom Oct 18 '16 at 16:06
  • Partly it's to get familiar w/ PEX. – Mike Oct 18 '16 at 17:08

    What fittings will you use to go from copper to PEX and back? – Sean Oct 18 '16 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.
