Hard Water in Illinois: How It Drives Drain Buildu

Hard water forms when groundwater picks up dissolved minerals along its path through soil and rock. In Illinois, the result can be higher mineral content in many residential water supplies. While hard water is generally not a health concern, it is a maintenance issue for plumbing systems.

As water moves through your home, minerals can precipitate—especially when heated, aerated, or exposed to changes in temperature. Over time, precipitation can turn into visible scale on faucets and showerheads and can also accumulate out of sight inside drains and pipe walls.
