Wait, are we talking about sour water or sour grapes? Either way, I'd keep it below 120 F, just to be safe. A) is the way to go, trust me.

Hmm, I'm going to have to go with C) 150 F. Anything above that and you might as well just throw the whole system in the trash.

I'm pretty sure it's B) 140 F. Anything higher and you're just asking for trouble with that sour water service.
