M/I Homes Water Quality Guide — Columbus, Ohio
M/I Homes Homeowners:
Know Your Water
M/I Homes builds with city water connections — and Columbus city water averages 18–22 GPG.
Columbus water averages 18–22 GPG hardness — classified as "very hard" by the Water Quality Association. This applies to all M/I Homes communities connected to Columbus-area municipal water.
What M/I Homes buyers need to know about their water
M/I Homes is one of Central Ohio's most active builders, with communities across Dublin, Powell, Westerville, New Albany, and Lewis Center. Their homes are well-built — but like every new construction in the Columbus metro, they connect to municipal water that averages 18–22 grains per gallon of hardness. That's classified as 'very hard' by the Water Quality Association.
New construction actually accelerates hard water damage. Flux residue from copper soldering, construction debris in lines, and brand-new appliances with no existing scale protection all mean your first year is your most vulnerable. A water softener installed before move-in — or within the first few months — prevents the damage that's hardest to reverse.

4 hard water risks for M/I Homes homeowners
These aren't hypothetical — they're the most common issues we see in new Columbus-area construction.
Scale in new plumbing
Brand-new copper and PEX lines are especially vulnerable to scale buildup in the first 2–3 years.
Voided appliance warranties
Hard water damage to dishwashers, water heaters, and washing machines is often excluded from manufacturer warranties.
Chloramine in showers
Columbus chloramine doesn't evaporate like chlorine — it absorbs through skin and lungs during showers.
Spotty fixtures from day one
Hard water leaves calcium deposits on new faucets, shower doors, and tile within weeks of move-in.
