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.
I just run the water for 10 seconds or so (feel for it to get colder) before I drink.
Ah god, this is gonna be a "those dumb Romans used lead pipes" moment for our civilization isn't it?
We do have quite a bit of lead pipe though.
Trade mag mentions it: https://www.waterworld.com/home/article/14071043/the-perfect...
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.
