Better check your plumbing because I hate to say it, PEX is everywhere and it's yet to be shown if there are long term effects on having plastic plumbing everywhere. My kitchen water tastes like plastic all the time.

PEX is fine. Water that sat in a PEX pipe is chemically indistinguishable from water held in a test tube, unlike what happens with water in PVC piping. Another indicator of fine-ness is that PE and PP tubing is used extensively in chemical process plants where high purity is required.

  I'd like to see a source for "chemically indistinguishable". Here is what I've read: https://www.ewg.org/news-insights/news/amid-pipe-wars-researchers-wary-plastic-pipes-leaching-chemicals https://www.ewg.org/news-insights/news/amid-pipe-wars-resear...

  But the water delivered to your house probably ran through miles of PVC pipe. What's a few feet more? I just run the water for 10 seconds or so (feel for it to get colder) before I drink.

    > miles of PVC pipe Ah god, this is gonna be a "those dumb Romans used lead pipes" moment for our civilization isn't it?

      No, nobody uses PVC pipe for water supply. We do have quite a bit of lead pipe though.

        PVC is quite common for water mains, Toronto has some: https://www.toronto.ca/services-payments/building-construction/infrastructure-city-construction/understanding-city-construction/water-sewer-mains/ https://www.toronto.ca/services-payments/building-constructi...

    What? Are you suggesting that most in the United States that most people have miles of water mains with PVC on the other side of the meter? Most PVC is not rated for potable water. In many localities (like nyc) it's a code violaton to use PVC on anything. I am a professional plumber. Btw, fun fact for you non-plumbers, pex as we know it was invented by a hardcore nazi.

      Most small water mains (like the 4"-6" stuff that runs down a residential street) are PVC in my region.
