First, let’s get one thing straight: your water isn’t haunted by a grumpy egg-laying poltergeist. The culprit is almost always hydrogen sulfide gas, which is just a fancy way of saying “the smell of a wet fart in a closed car.” This gas can come from natural sources deep underground, or from sulfur-eating bacteria that have decided your water heater is a five-star resort.
These bacteria don’t care about your morning coffee; they thrive in warm, low-oxygen environments. So if the smell is only from your hot water tap, you’ve found the party zone. Think of them as tiny, invisible frat boys who love sulfur and hate your nostrils.
