Polybutelene pipes?

[shilala]

Draw a glass of water and taste it. It's so nasty it's hard to get past your nose. Smells and tastes of chemicals.
They still use polybutylene in chinese faucets. And people still buy them, believe it or not. They come with a sticker on them that says "Let tap water run for 3 seconds before drinking water."
Yes, I'm full aware it sounds incredible.
