Nephi, Utah Water Hardness & Water Softener Guide
Nephi has hard water at about 18 grains per gallon — here is what that means for your home and how to fix it.
Where Nephi’s water comes from
Nephi’s water comes primarily from Salt Creek springs and wells. As that water moves through Utah’s mineral-rich geology it picks up calcium and magnesium — the minerals that make water hard and leave scale behind.
Is 18 grains per gallon hard?
Yes. Water above 7 gpg is considered hard, so Nephi at 18 gpg is hard — among the hardest water in the country. Hard water shortens the life of water heaters and appliances, spots dishes and glass, clogs fixtures, and dries skin and hair.
What CASA recommends in Nephi
A water softener is recommended to cut scale and protect your appliances. For drinking and cooking, pair it with a reverse-osmosis system, and add whole-home carbon filtration to remove chlorine taste and odor at every tap.
