Picture this: you’re filling up the bathtub after a long day, and it hits you—rotten eggs. That sulfur smell is almost always from bacteria hanging out in your hot water heater. It’s not the water company’s fault; it’s like that one friend who overstays their welcome at a party. The bacteria munch on a tiny bit of magnesium or sulfate, and they burp out that stinky gas.
But here’s the kicker: it’s usually only in the hot water. If your cold water smells fine, you’ve got a heater issue, not a pipe apocalypse. A quick fix? Flush your water heater or swap out the magnesium anode rod for an aluminum one. It’s like giving your heater a spa day—and your nose will thank you.
