Pex A fitting flow reduction

[Btyrer]

I have the 2021 IPC book, and I'm trying to find where it talks about how much each pex a and copper fitting reduces flow, and after how many fittings you have to upsize your line. I've been looking through "water supply and distribution", but I can't seem to find it. It's probably right in front of me, but I'm just not seeing it. Help?

Not too familiar with IPC... but I couldn't find any reference to any chart like that in the IPC when searching online. Appendix E for water pipe sizing using friction loss etc was the closest I could find but only had the word PEX on that page 1 time.

That would most likely be info from the manufacturer. Code doesn't go that in depth.

Uponor did have a Plumbing Design Assistance Manual (have one).

In the 2021 International Plumbing Code (IPC), information about pipe flow reduction due to fittings (like PEX and copper fittings) and guidance on when to upsize your line can typically be found under sections related to hydraulic calculations and sizing of water distribution systems. While the specific language may vary
