Salt-based water softener — confirm the district first

Two tall mineral tanks and a black brine tank of a salt-based water softener, plumbed with copper pipe in a garage.
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.

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.

    Shop salt-free conditioners

  • 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.

  • 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.

Check the sanitation district before installing.

Ask the agency on the sewer bill before you cut a brine drain.
