That sulfur smell isn’t sulfur itself—it’s hydrogen sulfide gas, and it comes from bacteria living in your well. These little guys eat the sulfur and magnesium in the water, then fart out that nasty egg odor. It’s gross, but it’s also totally fixable without calling in a priest.
Sometimes the smell is only in hot water—and that’s actually “good” news. Heat triggers a chemical reaction in your water heater’s anode rod, which can produce the gas. If it’s only hot water, you might just need a new rod. If it’s both hot and cold, you’re dealing with bacteria in the well itself—a slightly bigger, but still doable, problem.
