What does hard water actually do to a water heater?
Calcium and magnesium precipitate out when water is heated, coating tank bottoms, heating elements and tankless heat exchangers with scale — which cuts efficiency, then kills the equipment early.
In a tank heater, scale forms an insulating layer that makes the burner work longer for the same hot water and accelerates tank failure. In a tankless unit it clogs the narrow heat-exchanger passages — at Marion or Hiawatha hardness levels, an unprotected tankless can need descaling within a year. Every water heater we install in a very-hard-water town gets an honest conversation about softening first.

Do I actually need a water softener, or are you just selling one?
Depends entirely on your town and your tap. In Marion, Hiawatha and most well homes: genuinely yes. In Cedar Rapids, Robins, Iowa City and North Liberty, the city already softens — usually no.
This is the honest version of the answer, town by town, in the table above. Where the city softens centrally, we'll tell you to save your money — Iowa City even warns that stacking a home softener on already-soft water can corrode metal plumbing. Where the water runs 14–20 grains unsoftened, a properly sized softener pays for itself in equipment life. When the town publishes no number, we test at your tap before quoting anything.

Why is my water leaving orange or rust stains?
Iron. Eastern Iowa's aquifers carry a lot of it — Marion built a dedicated iron-removal plant in 2023, and Vinton runs three iron filters at its plant. In well homes, iron filtration is on you.
Municipal plants knock most of it down, but spring hydrant flushing (Marion flushes every April–May) can stir sediment into temporarily rusty water, and private wells in the Silurian-Devonian aquifer often carry enough iron to overwhelm a softener alone. Persistent staining is a test-then-treat problem: sometimes it's the supply, sometimes it's rusting galvanized pipe inside your own walls.

We're on a private well — what should we be doing?
Test annually for bacteria and nitrate (free or low-cost through Iowa's county Private Well Grant Program), and size any treatment equipment from a real tap test — never from a guess.
About 230,000 Iowans rely on private wells, and statewide testing regularly finds 10–30% of wells positive for nitrates or coliform in a given year — private wells are essentially unregulated after construction, so nobody is checking your water but you. Around Shueyville, Swisher and Toddville the standard mechanical-room lineup is a softener plus iron filter, with reverse osmosis at the kitchen tap where nitrate shows up.
