 So it's just on one faucet? Yes, and I thought it was a drain at first, but I did some testing, like filling a cup with hot water and walking a couple feet away and smelling it. No, it's the water. So have, well, geez, I don't know. That one whole, the one faucet thing's kind of stumped me. Does it smell like rotten eggs at all, like sulfur or anything like that?
