My water smells of corpses!
I've found several topics talking about a "sewer smell" coming from the plumbing, but as I'm not very familiar with sewers (other than the fact that they probably don't smell good), I'm not sure if it's very accurate to describe this smell like that.
What I can say is that my water smells like a dead animal. The smell has actually made it into my home office, but it seems to be coming from the toilet in the nearest bathroom.
I've noticed this smell a few times when I was outside, too, mostly around my septic tank area. It was hard to pinpoint, though, as I'd only smell it when I walked around certain areas.
