Running a softener without enough salt is like running a car without oil. It’s a slow-motion disaster. Your brine tank will fill with sludge, and the resin beads (the real heroes) get coated in calcium gunk.
Replacing those beads costs hundreds of dollars. That’s a lot of money for something you could have avoided by tossing in a $10 bag of salt every few weeks.
Your wallet will throw confetti. Your pipes will sing. Your glasses will sparkle like a vampire’s teeth.
