That stink is almost certainly hydrogen sulfide gas. Think of it as the fart of the earth, trapped deep underground where your water comes from. When it escapes into your pipes, it brings that classic, eggy greeting.
This gas forms when organic matter decays deep in the ground. Or, it can come from certain rocks that contain sulfur, like a natural chemistry experiment beneath your feet. Don’t worry, it’s usually not dangerous at low levels—just incredibly rude to your nostrils.
Hot Water Makes It Worse
Ever noticed the smell is stronger in the shower than from the kitchen tap? That’s because heat is a bully. Warm water forces the gas out faster, so your morning shower becomes a stench-therapy session.
It’s like when you heat up old leftovers—the smell gets louder. Your water heater can actually breed this gas if it sits too long, turning your cozy bath into an egg incubator. Yuck.
