Eagle Mountain water softener FAQ
Short answer: Eagle Mountain water is hard to very hard (about 6.3–9.0 GPG on surface water, 14–25+ GPG when city wells dominate). Most homes of 3–5 people fit a 48,000-grain softener, and your installed price is quoted after a quick check of your home.
Hard water
How hard is the water in Eagle Mountain, Utah?
Hard to very hard. Eagle Mountain City's 2025 water quality report (system #UTAH25142) shows about 6.3–9.0 grains per gallon (GPG) when your area gets surface water from the Central Utah Water Conservancy District (CUWCD), and about 14–25+ GPG when the city's deep wells make up most of the blend. This site uses about 16 GPG (274 ppm) as the typical blended figure. Read more
Where does Eagle Mountain get its water?
From two sources: city-owned deep groundwater wells and treated surface water bought from the Central Utah Water Conservancy District (CUWCD). Both are listed in the city's 2025 water quality report. Read more
Why does my water hardness change during the year?
Because the city blends two sources and the share from each shifts with season and demand. Well water is much harder than the surface water, so summer, when the wells run more, is usually when your water is hardest. Read more
What does grains per gallon (GPG) mean?
It's a common unit for water hardness. 1 grain per gallon equals 17.1 mg/L (ppm). The U.S. Geological Survey calls anything over 180 mg/L (about 10.5 GPG) "very hard." Read more
Is Eagle Mountain water safe to drink?
Hardness is a nuisance, not a health standard. For safety and compliance results, check Eagle Mountain City's annual Consumer Confidence Report. This site doesn't give health advice. Read more
What does hard water do to my home?
It leaves white scale on faucets and shower glass, spots on dishes, and scale inside water heaters and appliances, and it makes soap lather poorly. Read more
How do I find out how hard my own water is?
Check the city's latest water quality report, or test your tap with a hardness strip. A free tap test is included with a quote request. Read more
What is TDS, and does a softener lower it?
TDS means total dissolved solids. The city's 2025 report shows TDS from 148 to 1,320 ppm depending on the blend; the EPA's non-enforceable taste guideline is 500 mg/L. A softener does not lower TDS. A reverse osmosis (RO) system at the kitchen sink does. Read more
Sizing
What size water softener do I need in Eagle Mountain?
A 3–5 person household usually fits a 48,000-grain softener. Six or more people, or well-heavy water (18 GPG and up), usually calls for 64,000 grains. You can check your home in the sizing calculator on the home page. Read more
Should I size my softener for summer or winter water?
Size it to the hardest water you're likely to get, which is your summer, well-heavy number, not the winter low. Read more
Cost
How much does a water softener cost in Eagle Mountain?
Your installed price is quoted after a quick check of your home: system size, your existing plumbing and any add-ons like reverse osmosis. Request a quote and the installer confirms the price in writing before any work. Read more
What makes the installed price go up or down?
Size, plumbing and add-ons. Bigger households and harder water need a larger unit, homes without a softener loop need extra plumbing, and adding reverse osmosis drinking water adds cost. Read more
Does my home need a softener loop?
Many newer Eagle Mountain homes already have a garage softener loop, drain and outlet. Without one, extra plumbing work is needed. You can upload a photo of your pipes with your quote request so the installer can check. Read more
Do I need an in-home sales visit to get a price?
No. You can request a quote online, and a photo of your garage pipe loop helps the installer quote without a sales visit unless you want one. Read more
Salt vs. salt-free
What's the difference between a salt-based softener and a salt-free system?
A salt-based (ion-exchange) softener removes the calcium and magnesium that make water hard. A "salt-free" system is a conditioner: it changes how minerals behave to cut scale, but the water is still hard. Read more
Do salt-free water softeners work?
They don't remove hardness. Salt-free conditioners (usually template-assisted crystallization) reduce scale buildup, but the water stays hard and spotting can continue. Look for third-party testing; the Water Quality Association lists certified products. Read more
Which is better for Eagle Mountain water, salt or salt-free?
At Eagle Mountain's typical ~16 GPG, a salt-based softener is the usual choice if you want truly soft water. If you can't add a drain or want no salt and mainly care about scale, a conditioner is an option. Read more
Does a water softener make my water salty?
No. It adds a small amount of sodium, not salt you can taste, and the amount rises with how hard the water was. Many homes leave the kitchen cold tap unsoftened or add reverse osmosis for drinking water. Read more
Drinking water
Why add reverse osmosis along with a softener?
A softener removes hardness but doesn't lower total dissolved solids, sulfate or nitrate. An under-sink reverse osmosis system does, for drinking water and ice at the kitchen sink. Read more
