Local Water Quality
Understanding Water Quality in O'Fallon, Illinois
O'Fallon publishes unusually detailed information about its municipal water system. The city's published water-system information lists a hardness range of 9–15 grains per gallon, or approximately 150–250 mg/L.
The city also reports a pH of 7.1–7.5 at the entry point, a distribution-system pH of 7.0 or greater, and a chlorine range of 1.0–4 ppm.
O'Fallon purchases water from the Illinois American Water treatment plant in East St. Louis and distributes that water through the city's system. The city's Water Division performs water-quality sampling and testing and maintains system infrastructure including water mains, storage tanks, pump stations and valves.
For homeowners, water in the 9–15 grain hardness range can produce noticeable scale and spotting depending on the individual home and water use. A water softener may be appropriate for households that want to reduce hardness-related problems.
Soft Flo Water Pros offers free in-home water testing in O'Fallon to measure the water at your actual tap before recommending treatment.

Do you install in new construction?
Yes. We install water treatment systems in new homes all the time, and we can often tie into existing plumbing during the build or after move-in.

Soft water helps water heaters, dishwashers, and washing machines run more efficiently and last longer by reducing scale buildup.
