But wait—if the beads are now covered in calcium, they can’t keep swapping. They’d get “full” after a few hundred gallons. That’s when the salt does its real heavy lifting.
The system flushes a brine solution (super salty water) through the resin tank. The high concentration of sodium ions literally kicks off the calcium and magnesium from the beads. Think of it like a game of musical chairs where the sodium ions yell, “Move over, we’re sitting here now!”
The flushed-out hard minerals go down the drain, and the beads are “recharged” and ready to soften again. That’s why you have to refill the salt bin every few weeks—you’re feeding the system its secret weapon. (Pro tip: don’t use table salt; the tiny grains can clog everything. Use pellets or crystals made for softeners.)
But Isn’t Salted Water Bad for Me?
I hear you—salt in water sounds like a recipe for high blood pressure. Relax. The amount of sodium added is tiny, usually about 7.5 to 20 milligrams per glass of water. To put that in perspective, a slice of bread has about 100 milligrams. You’d have to drink the ocean to get worried.

If you’re still nervous, you can use potassium chloride salt instead. It’s more expensive, but it adds potassium (which is actually good for you) instead of sodium. Your plants might even thank you.
The real irony? The salt itself never actually touches your drinking water. It only interacts with the resin beads during regeneration. The water you drink has already been swapped and filtered. So no, your morning coffee won’t taste like the Dead Sea.
