This question is obviously intended for those that live in places where tap water is “safe to drink.”
I live in Southern California, where I’m at the end of a long chain of cities. Occasionally, the tap smells of sulfur, hardness changes, or it tastes… odd. I’m curious about the perspective of people that are directly involved and their reasoning.
Not a water person, but it might be the fire departments fault. If they use a hydrant upstream of you it flows so much water so fast that it can stir up some older stuff that’s been sitting in there a while.
