red & blue pipe: PEX?

[Peanut]

I don't get to see much of that ol' PEX stuff. 1999 home. Red plastic for hot water, and blue for the cold. Has that milky look to it. The only parts visible were stubs. Is that Pex?

Not that I can't believe it, just surprised, is all.

Any pictures? Red and Blue lines are usually PEX. Has a "milky look", what has a milky look?

[Peanut]

No photos, but yeah, seems to look like milk is mixed in. Can't describe it. Is has to be pex. It can't be anything else. I know it comes in white, red and blue.

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.

Sounds like PEX to me. I see red and blue alot, sometimes mixed, I don't think the color matters, all the same stuff. red is "supposed" to be used for hot but I don't think it has to.

I haven't seen anyor read anything about black PEX. What I have read states it's not UV stable.

Last year, my 13 and 15 year old sons installed this in a house we've been toying with.

Copied and pasted from SlantFin site listed above;

"Black oxygen barrier tubing is UV protected for up to 3 months. Non-barrier black tubing is UV protected for an unlimited amount of time".

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?

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.

If PEX (Red or Blue) has a milky color I would say that it has been stressed or bent to much. I think that it has a limit of a 6" arch or sphere for a bend. The milky color will show up in the stressed areas.

Yes, it's one of nature's cruel jokes. God is actually a woman, who is more than willing to extend the suffering of any man.

Brian,

I will have to remember that. I am roaring in laughter. Or as they say in computer lingo LMAO

Could it be that life only seems longer when married?
