Water Softeners & Plumbing in Franklin, Indiana
Franklin's public water comes from Indiana American Water's Johnson County system, the same groundwater system that serves Greenwood. Its 2025 report shows average hardness of about 21 to 22 grains per gallon (358 to 382 ppm), which is very hard. I'm a short drive down I-65 from Franklin, and I do free in-home water tests, softener and RO installs, backflow work and plumbing repair.
City Water or a Well?
Inside Franklin, most homes are on Indiana American Water. Out in the county, some homes run on private wells, and well water can bring its own problems. The Indiana Department of Health notes that sulfate and sulfide minerals occur naturally in Indiana groundwater, and hydrogen sulfide gives water a rotten-egg smell. It recommends testing private wells at least once a year. I test both.
