    I think they are referring to plasticizers leaching into the water from the polyethylene. Here's a page that mentions their potential health risks:

    I'm not a sicentist, and my material science experience is mainly in metals, so I have no idea if any of this is applicable to Pex.

    I'll drink the tap water, cuz I'm going to die in my sleep...

    Just like my Granddad did, peasefully in his sleep, not like the rest of the screaming passengers in his bus when he drove over the cliff.

    I would expect no less from: This self-help alternative medicine site....

    No matter that no one but alternative medicine types can find any plasticizers leaching from plastics used in plumbing or water treatment, the medical field, the food and beverage packaging industry etc..

    Well, when god invented electricity for refrigerators, it helped cut down on food poisoning from spoiled meat. But the smoke from the power plants causes some illnesses, including cancer. It's a tradeoff, and it's called "progress". We still enjoy the electricity, and we continue to make progress to eliminate the smog. One way to do that is nuclear, which overall is much cleaner, but it has the issue of fuel disposal. More progress.

    There will be some missteps. Polybutylene was a misstep. There will be others. More progress.

    PEX is no longer what you would call "new". We will find out soon enough if there are any chemical leaching problems. A high quality carbon-based filter rated for lead and VOC's used on your drinking water will take away those worries. And if you are talking bottled water, dont even go there. Recent reports in the news indicate that much of it is bottled right out of municipal supplies. Maybe a little filtering, a few mineral added for flavor.

    Is PEX just slightly easier to damage if you poke it with a nail....yes. We will just have to get used to that, like we got used to wearing seatbelts. More progress.

    Take vaccines. Literally hundreds of millions of people are live today, or at least lived to a ripe old age, due to NOT dying of polio, smallpox, etc.etc. Very occasionally, does a person get ill or even die because their genes were adverse to the vaccine? Yes. More progress. Your choice.

    Sorry, it isn't Sunday, so I shouldn't be preaching!

    If I were in your shoes, I would evaluate cost differences, the cost of filtering if I thought that was important, and the cost and ease of installation, and make a decision accordingly. I try to avoid sensationialistic , non-scientific reports on these issues.

    I forgot this.... Polyethylene has been used in well and city potable water systems since the 1960s. IIRC, PEX is a German invention and their?Euorpean water quality regulations are tighter than our EPA regs. And Pex has been used in Europe for roughly 35+ years.

    BTW, PB is the most widely used tubing/pipe in the world, and not an inch of it is used in the US.

    Default Go Pex

    I just plumbed my entire house with PEX - a great experience. Install went fast - no leaks. Its quiet. I used a modified manual method. I have a manual across the basement, with 3/4" runs to each each bath/kitchen/utility. I ran 3/4 right up to each tub and shower.

    Regarding the PEX and water chemical issue - I keep thinking about the bottled water we all drink three times a day. It sits in plastic a lot longer that the water in my house sits in the PEX tubing.

    Go out and have a doughnut , some coffe, a couple strips of bacon and smoke a cigarette....

    you will feel much better...


    something has got to kill you....

    why die healthy???
    Only trouble is, the law prevents your health care providers from allowing you to die a nice, natural death. They have to do everything they can to keep you alive, even if you're 90 and only alive because of your meds and your pacemaker. Just went through this with my grandma last year, so the topic is fresh in my mind . . .

    But as for PEX? . . . yeah. Drop in the bucket.

    The PRACTICAL answer she wanted is: copper freezes and breaks RELIABLY. Pex does not. Use PEX.
