What to do in Salt Lake City
Salt-based water softener
No district prohibition on a brine drain turned up.
A salt-based softener is the thing that actually removes hardness. Size it from your grains and how much water you use, not bathroom count. It needs a drain.
Hard water. A salt softener is the box that actually removes it.

Also for the kitchen
Under-sink reverse osmosis
Cloud RO is an under-sink reverse osmosis system — NSF/ANSI 58, kitchen tap, not a whole-house tank. The primary button is a tagged Amazon under-sink RO listing. Cloud buy-direct and Waterdrop sit under that. Check the exact listing if PFAS is why you are shopping. A certifier-listed pitcher is the cheap first step.

Other options that still fit
Salt-free conditioner
A salt-free conditioner changes how scale sticks. It does not soften. Soap and spots stay closer to untreated. No brine line.
Whole-house carbon for chlorine
That is chlorine. A whole-house carbon filter with an NSF/ANSI 42 chlorine claim is the usual match. A softener will not take chlorine out.
Test the tap first
A homeowner kit is a start. It is not a state-certified lab. Use a certified lab when the decision is expensive.
Softener vs carbon vs under-sink RO
A sketch for Salt Lake City, tied to the best match above. Not a quote.
| Box | What it does | Ballpark (estimate) |
|---|---|---|
| Salt-based softenerBest match | Removes hardness. Needs a drain. Illegal in some sewer districts. | About $800–$2,500 for a common residential unit (equipment). Installed jobs run higher. |
| Whole-house carbon | Chlorine or chloramine taste — match the listing. Does not soften. | About $400–$1,800 for a typical tank-and-head kit (equipment). |
| Under-sink reverse osmosisBest match | Kitchen tap. Check NSF/ANSI 58 if PFAS or nitrate is why you are shopping. | About $200–$600 on Amazon search; named under-sink units vary. |
These are ballpark equipment ranges, not installed quotes and not what a dealer will write on a kitchen-table sheet. Prices move. Confirm the sewer rule before you price a brine tank.

How to get your water tested
The report on this page is for the public water system. It is not a test of the faucet in one house. Pipes inside a house can change the water.
For a test of your own tap, use a state-certified drinking-water laboratory. Start with EPA's page for finding certified drinking-water labs.
If your water comes from a private well, test it once a year. A city water report does not cover a private well.
