Here’s the thing. That milky look is almost always caused by tiny air bubbles. Think of it like opening a soda can.
When cold water heats up in your water heater, it can trap dissolved air. As the hot water flows out of the faucet, the pressure drops, and those bubbles explode into a cloudy fog.
It’s perfectly harmless, I swear. If you let the water sit in a glass for a minute, the bubbles rise and the water clears from the bottom up. Try it! Watch the magic happen.
But Why Now? Is My Heater Broken?
Not necessarily. This can happen more often in winter. Cold water holds more dissolved air, so when it heats up, it releases more bubbles.
Your water heater might also be set a little too high. Super hot water releases air faster. Or maybe you just got a new water heater—they can stir up more air initially.
Still, if the cloudiness never clears after a minute, that’s a different story. But we’ll get to that in a sec. Don’t worry yet!
