Tomy, if you get wour water from a municipal source, as opposed to your own well, then chlorine has been added to kill bacteria. Rinsing with that water will not contaminate your equipment. Lime is an inorganic mineral, as are other components of the water, and will not grow in your wine.
Many of us feel, however, that if you are adding water to a wine concentate kit, and your water has a high mineral content, you should use distilled water from the grocery store.
What part of the country are you from? I spent 20+ years in the water treatment industry and may be familiar with your water quality.
