The only pex tube that I am familiar with (Slant Fin)comes in Red, Black and Milky White. I usually only see red. All pex tubing is suitable for domestic water lines (hot or cold).

Only the pex tubing with an oxygen barrier, identified by "DIN 4726" imprinted on the tube is suitable for heating systems.

The black has to do with UV protection.

I haven't seen much in my area used for domestic, but it sure makes sense to distinguish red/blue-hot/cold.

Welll,now I have read about it. Persionally I like to keep my concrete cold.

Darn near 80 a day ago.

Don't get me wrong but is it safe to assume it could (why would ya want to) to use it for potable water?

"The PEX that you see at the Home Center is used for domestic water supply lines only, not for heating systems. This tubing does not have an oxygen barrier, which is not needed for domestic water applications. If you don’t see “DIN 4726â€

Good morning Charlie,

You may be right,

I may be crazy...

They used to think lead was a great medium for water supply.

What about Vioxx?

Is the Marlboro Man really sexy?

Is it safe to assume copper is safe?

How about aluminum or plastic for our food and drink?

Or the crap they inject into our food supply?

Does being married really make a man live longer?

Maybe that particular man would have lived longer had he been single!

I have never used Pex for potable, I'm considering it though.

It would sure be fast and easy to install.
