Why does heat pex from Wirsbo say for non potable only? I thought the only difference was that it has the oxygen barrier.

You can use it.

Same stufff. HePEX has the barrier. That's the onely difference.

Where did you hear it is for non potable onely? Wirsbo? That's not what they've been telling me.

Right on the

pex itself. We are using 3/8 - 3/4 on a job right now. I was hoping to use it for some potable connections in a tight spot. I was under the impression that they were the same but the he-pex was more expensive because of the barrier. BTW This is the first time using this product and are so far very pleased.

That and........

the lack of an NSF cert. Use it for potable water and you will undoubtedly be removing it and installing AquaPEX......at your expense.

I agree about

not using it due to that reason. I just was wondering what is the difference? Do they actually differ other than the certification, and if so what harm could the oxygen barrier cause in a potable situation? It seems like this is to prevent accidental cross contamination at a later date by someone just "tapping into" a water/heat pipe.

Not in my town! MASS

We don't need no stinking NSF badges!!! I'm in the Peoples Republic of Massachusetts and whatever PEX I put in is not approved anyway.

Use it onely if you don't have the inspector comming by. Or, if you want to, buy the same stuff (no EVOH coating)called Aquapex and use that.

Same stuff. Different Certs.

Okay

So this sounds like its the same stuff and I'm thinking it is, then why doesn't it also say "Not for Installation in Mass". Are you saying that pex is sold in Mass but not legal to install in Mass? How are radiant jobs approved?

Unknown

Onely approved for heating.

Still can't use it (leagally) for potable water systems. My bad.

Heat Pex

No NSF certs so not legal for potable water anywhere. Aquapex is less costly and is NSF sealed. Heat pex is more costly due to added manufacturing cost of applying oxygen barrier and protective layer. The stuff comes out of the same extruding machines. But even if its your house don't use None NSF pipe. When you go to sell, the home inspector will probable spot it and you will have an expecive replacement project at a time when you can least afford it.

It's the same.......

.....stuff. As others have said, it comes out of the same extruder, just no O2 barrier on HePex. The ONLY difference is that HePex is not tested and certified NSF, only because it didn't make sense for Wirsbo to pay for the certification. I don't blame them, I wouldn't pay for it either!!

Although we all know it will work, the problem comes up with using non-NSF-certified tubing for your potable water. An inspector will shoot it down, and then you've got a real problem on your hands. Besides, the Aquapex costs a lot less!!!!!!

Thanks guys

For clarifying this.

Steve Eayrs

John Starcher I believe you possibly meant to say.......

there is a barrier on the hepex, not as quoted "no barrier on hepex"???

Steve

John Starcher_4

You are right sir!!!!

....there is an O2 barrier on the HePex, not the regular Pex.

Please forgive the typo..

DUAL RATING

If Wirsbo has decided that Aqua Pex is the only one covered under ANSI/NSF 61, so be it. But, there are many maufacturers who dual rate there barrier tubing. Zurn, for one, specs their barrier tubing for ASTM F876/F877, CSA B137.5, AND ANSI/NSF 61; suitable for potable water. Maybe all the Wirsbo hardcore oughta soften, It's NOT the only game in town.

Weezbo

Say have any of you seen this new plastic sheet goods that cuts with a cheet rock knife inter locks and allows you to just snap wirsbo or stadler or rehau right into it pour gypcrete go home call it good? it looks like lego locks...what the deal! I just cant find it yet. i saw it used on like somolly broken down house or remodel the universe or some telivision show...i didnt catch a manufactures name:(

What is this doing on this thread? (NM)

More on pex

The reason we've gone with Wirsbo is twofold. First my supplier is a close friend and promotes this line, and to start with a new product it made sense to go with a major brand with a complete line. I have so far been impressed by the propex connections and it appears less costly than other fitting methods. The dual rated tubing does seem more convenient, but you can't have it all can you. Btw I had met Dave from RTI a couple years ago and was very impressed by both him and his product.
