Inside your water heater is a metal rod called an anode rod. It’s a sacrificial hero. It attracts rust and corrosion so your tank doesn’t turn into a pile of orange dust. But sometimes, it gets too friendly with the sulfur in your water.
If the water is high in sulfate, that magnesium or aluminum rod can react with it. The result? You guessed it: egg fart aromas. The sneaky part is it only happens when you first run the water. After a few seconds, the smell vanishes.
Don’t throw your hands up yet. You can replace that rod with a different type, like an aluminum/zinc alloy. Or you can just remove it entirely, though that’s a last resort. It’s a cheap part, and swapping it out is a weekend DIY project that makes you look incredibly handy.
When in Doubt, Check the Drain
Here’s a nasty little secret: that funky smell could be coming from your drain, not the water itself. Water sits in the P-trap under the sink. If it evaporates because you don’t use that sink often, sewer gases come right up.
Ever lean over to turn off the shower and get a whiff of the drain? That’s the culprit. The fix is embarrassingly easy: pour a bucket of water down the drain. Or, for a party trick, drop half a cup of baking soda followed by vinegar. It fizzes like a science fair volcano and kills the smell.
If that doesn’t work, your drain might have a biofilm or mold. That’s when you break out the bleach or a special enzyme cleaner. But honestly? Nine times out of ten, it’s just dry pipes. You’re welcome.
