Before you spend a cent, test your water. Fill a glass, let it sit for five minutes. If the smell vanishes, your sulfur is dissolved gas—easy to remove. If the smell sticks around, you’ve got sulfide minerals—harder to fix. This is the cheapest science experiment you’ll ever do. No lab coat required.
So there you go. Whether you aerate, chlorinate, ozonate, or just throw activated carbon at the problem, you can banish that rotten egg stink. Your guests will stop asking if you’re cooking cabbage. Your showers will smell like rain again. And you’ll finally understand why people call water “the elixir of life”—not the elixir of “what died in here?”
