Check the sanitation district before installing. No City of Sacramento prohibition comparable to LACSD Measure S turned up. California still authorizes local agencies to restrict self-regenerating softeners by ordinance. Ask Utilities / the sewer side of the bill.

If soap will not lather and you want a salt softener
Salt-based softener: two mineral tanks and a brine tank.
Ask the agency on the sewer side of the bill before you cut a brine drain. California lets districts restrict self-regenerating units. A “banned in California” blog is not your district.
If you are shopping a PFAS listing for the kitchen
Under-sink reverse osmosis: filters, tank, and a second faucet.
A pitcher or under-sink RO whose exact model is listed for PFAS under NSF/ANSI 53 or 58. The RO shop link is Waterdrop. Pitchers stay on a tagged Amazon search. We have not picked a model.
Sacramento is a moderate hardness / chlorine file. Do not paste Phoenix grains onto the American River.
What the 2025 CCR prints
Hardness for 2023–2025 is listed 15–154 mg/L (0.9–9.0 gpg). Some printed averages sit around 4.9 gpg. That is USGS soft-to-hard depending on the well vs the river plants (Sacramento River WTP and E.A. Fairbairn).
The residual disinfectant on the table is chlorine as Cl2, not chloramine.
Salt discharge
check-district. No Measure S copy turned up for the city.
