A: Yes. If you are on a low-sodium diet, potassium chloride works in the 40278. However, it is 3x more expensive and can cause "mushing" in the brine tank. Clean the tank yearly if you use potassium. Disclaimer: Manufacturer SKUs change

The 40278 hits the "sweet spot" for the average homeowner. It is more reliable than budget units and half the price of a commercial Fleck. However, if you have extreme hard water (over 30 grains), upgrade to a dual-tank or high-capacity Fleck. Is the 40278 Water Softener "Salt Free"? (No, and here is why you don't want that) Some marketing gimmicks try to sell "salt-free softeners" (Template Assisted Crystallization). The 40278 is not one of those. | Feature | | Budget Cabinet | Fleck
