Here’s a hilarious little fact: your water heater is the perfect Airbnb for sulfur bacteria. It’s warm, dark, and full of minerals—basically a spa for microbes. If you only notice the smell on the hot side of your faucet, your water heater is almost certainly the host.
Turning up the temperature to 160°F for a few hours can kill off these bacteria. (But watch out—don’t scald yourself and check your manufacturer’s guidelines first!) It’s like giving your water heater a hot-tub detox—sort of satisfying, isn’t it?
Is It Always Bacteria? Or Could It Be Your Well Itself?
If the smell hits you from both hot and cold taps, the trouble is likely in your well water. Maybe your well cap is loose, letting surface water trickle in with extra organic matter. Or, your well might have a low level of oxygen, which makes sulfur bacteria thrive like party animals.
Why Does My Water Smell Like Rotten Eggs, Sewage or Fishy?
Don’t panic—this is still a “fun fix” kind of problem. A simple shock chlorination of your well can nuke the bacteria and freshen everything up. It’s basically a bubble bath for your water source. How’s that for a weekend project?
