My well (300' deep) water sometimes smells like sulphur...also the rubber flange and stopper in my sink (for my disposal) get covered w. yucky gunk. I am horrified when I remember to remove the parts, soak in bleach and water and then scrub w.a toothbrush.
I am afraid to ask what "smells like hiney" means so I won't. Unpleasant odor, I gather.
