Radiant PEX vs. Water PEX

[Ezzie]

I have some radiant floor PEX left over from doing the in-slab install and wondering if there would be a problem using it for a few runs for "potable" water in the shop.

I know you can't use the Water PEX for radiant heat piping since it lacks an oxygen barrier, but what about the other way around??

I would not think it an issue, since the barrier is on the outside. Check with the manufacturer, it may not be rated potable.

I own a plumbing company it is fine potable water I plumb whole house with it.

The oxygen barrier PEX is designed to keep oxygen from escaping the tubing and rusting ferrous metal components of the heating system.

I doubt that would harm potable water in any way.

I say go for it.

OK, thanks guys. We'll use it up then for some of the plumbing. I couldn't really see any issues with it but thought I'd ask around first.
