Best match for Frisco
Salt-based water softener
No district prohibition on a brine drain turned up in the current file.
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.

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 catalytic carbon for chloramine
Catalytic carbon with a chloramine claim (NSF/ANSI 42 for chloramine). Regular chlorine carbon is the wrong box.
Under-sink reverse osmosis
The under-sink RO we actually run is Cloud RO — NSF/ANSI 58, kitchen tap, not a whole-house tank. Check the exact listing if PFAS is why you are shopping. Shop Amazon first for under-sink RO, or buy Cloud direct. Waterdrop is a tankless option if you want that path. A certifier-listed pitcher is the cheap first step. Nobody is paying for a medical claim.

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.
On the report
- Water utility
- City of Frisco Public Works / NTMWD
- Hardness
- Total hardness as CaCO3, Wylie column, 200 ppm (range 96.0–200). Labeled NTMWD Wylie source — not a blend we invented. 2025 Water Quality Report. — City of Frisco 2025 Water Quality Report
- Disinfectant
- Chlorine (chloramines) Frisco column. Action / quarterly data level 2.16 ppm. Lowest single sample 0.3. Highest single sample 3.86. MRDL 4. Chloramine, not free chlorine only. Narrative says NTMWD uses chloramines. — City of Frisco 2025 Water Quality Report
- Brine / salt to the sewer
- No district prohibition found in current research. Searched city water and sewer pages for a residential self-regenerating softener or brine-drain ban like LACSD Measure S. None turned up. Ask the sewer agency on the bill before you cut a brine drain.

Extra context besides the utility report and the chart above — geology, an unregulated table, or a published study. Not a second set of printed tap numbers.
- MicroplasticsWHO’s 2019 review examined studies that found microplastic particles in treated tap and bottled water in many places. That is a published-occurrence finding, not a number from this city’s water-quality report, and we do not invent a particles-per-liter count for the tap.Microplastics in drinking-water — World Health Organization

Frisco drinking water is City of Frisco Public Works, purchased from North Texas Municipal Water District Wylie. No City of Frisco residential softener ban like LACSD Measure S turned up. Ask the sewer agency on the bill before you cut a brine drain. This is not a legal opinion.
The 2025 report prints Wylie total hardness 200 ppm (96.0–200). Frisco chloramines 2.16 ppm (0.3–3.86). TTHMs highest detected 36 ppb. HAA5 highest detected 22 ppb. Those are labeled columns — not a blend with Wylie or Leonard residuals. Kitchen shopping stays the Cloud RO / Waterdrop path already used on other cities if a listing is why you are looking.
