If your water stays cloudy after sitting out, it might be something more serious—like a failing water heater or a broken filter. Also, if your water smells like rotten eggs, that’s hydrogen sulfide gas. It smells like a swamp’s armpit, but it’s usually harmless.
However, if it smells like gasoline, chemicals, or bread (yes, bread), don’t drink it. Get it tested immediately. But for most of us, cloudy water is just a quick visual prank. It’s your pipes playing a harmless joke.
