You are right. Water smells like sulfer for two reasons, either it has sulfur from mineral content (only in wells, not municipal water since they filter it out) or it is bacterial contamination, usually in pressure tanks (you don’t have this), or in water heaters or water softeners. I suggest that you disinfect the softener brine tank and the resin bed with chlorine to kill the active bacteria. I have seen it many times when inspecting properties.
