What to do in Paradise Valley
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 Paradise Valley, 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.
On the report
- Water utility
- EPCOR Paradise Valley
- Hardness
- 12 grains per gallon on the unregulated substances table leaving the treatment facility (year sampled 2022). Single printed value — not a range. The FAQ prints approximately 12 gpg and classifies Soft <1, Slightly Hard 1–3.4, Moderately Hard 3.5–6.9, Hard 7–10.4, Very Hard >10.5 gpg. 12 gpg is Very Hard on that scale. The report does not print hardness in ppm. We do not invent a conversion. — EPCOR 2025 Water Quality Report — Paradise Valley (PWS AZ0407056)
- Disinfectant
- Chlorine residual 0.82 ppm highest running annual average (range 0.74–0.94), MRDLG 4 / MRDL 4.0, 2025 distribution-system table. Water additive used to control microbes. The FAQ says chlorine is added as a disinfectant — not chloramine. — EPCOR 2025 Water Quality Report — Paradise Valley (PWS AZ0407056)
- Brine / salt to the sewer
- No district prohibition found in current research. No Paradise Valley or Maricopa County sanitation prohibition comparable to LACSD Measure S turned up in the research for the utility's report. Still ask the agency on the sewer bill before cutting a brine drain — rules change by jurisdiction, not by metro-area folklore.
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 laboratory on the Arizona Department of Health Services list of 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.

Paradise Valley drinking water is EPCOR Paradise Valley (PWS AZ0407056). The 2025 report says EPCOR provides water to approximately 5,300 service connections in the Paradise Valley district. The source is groundwater from the West Salt River Valley (WSRV) Sub-Basin, bordering the Phoenix Mountains. The report also names an interconnect with the City of Phoenix 24th Street plant. This page is AZ0407056 chemistry — not Phoenix, Scottsdale, Fountain Hills, Anthem, Sun City, Sun City West, or San Tan Anthem. We do not copy Phoenix-plant table rows onto this city.
No Paradise Valley or Maricopa County residential self-regenerating softener ban like LACSD Measure S turned up. Ask the agency on the sewer bill before you cut a brine drain. This is not a legal opinion, and it is not a statewide finding.
The unregulated table leaving the treatment facility (year sampled 2022) prints hardness 12 grains per gallon. The FAQ prints approximately 12 gpg and lists Soft less than 1, Slightly Hard 1 to 3.4, Moderately Hard 3.5 to 6.9, Hard 7 to 10.4, and Very Hard greater than 10.5 gpg. 12 gpg is Very Hard on that scale. The report does not print hardness in ppm. We do not invent a conversion.
Chlorine residual 0.82 ppm highest running annual average (range 0.74–0.94) on the 2025 distribution-system table. MRDLG 4 / MRDL 4.0. Water additive used to control microbes. The FAQ says chlorine is added as a disinfectant. That is free chlorine, not chloramine.
Also printed on the 2025 distribution table: TTHMs 29.3 ppb (range 3.7–41.1), HAA5 4.4 ppb (range ND–8.3). Those are printed rows, not a medical claim. Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.
