Best match for Big Flat
Whole-house carbon — match chlorine vs chloramine
No district prohibition on a brine drain turned up in the current file.

Open the CCR for chlorine vs chloramine, then match that claim. A 42 chlorine listing is not chloramine.
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.

Confirm hardness on the current CCR before buying
Open the current CCR for grains. This file does not invent a number from a ranking site. A salt softener needs a drain if it is legal at the address.

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.
