Now imagine the water’s journey to your glass. It starts out clean, then takes a ride through old pipes. Copper pipes can leach a metallic tang, while iron pipes—which some cities still use—add a rusty backbeat. Your tap is basically serving you a vintage 1950s sediment cocktail.
Plastic pipes aren’t innocent either. They can release phthalates—chemicals that make your water taste like a new shower curtain. Yes, you’re drinking the flavor of a bathroom renovation. Cheers.

Temperature: The Silent Saboteur
Hot tap water is a common mistake. Hot water dissolves more minerals and pipe gunk, so drinking it is like ordering the house special of sediment stew. Always use cold water and let it run a few seconds—unless you enjoy the taste of early 20th century plumbing.
And what about that plastic taste from a water bottle you left in a hot car? That’s BPA and other compounds doing the cha-cha into your drink. The same thing can happen with tap water sitting in a hot pipe. Your water might be having a chemical party you weren’t invited to.
