Best match for Brownsville
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.
Also for the kitchen
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.

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.
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 Brownsville, tied to this file’s best match. Not a quote.
| Box | What it does | Ballpark (estimate) |
|---|---|---|
| Salt-based softenerThis file’s 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 osmosisThis file’s 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.
