Okay, full honesty: you have to buy bags of salt. And you have to haul them from the store. It’s like having a pet that eats rocks and then burps them out. But most modern softeners have a low-salt indicator light, so you’ll know exactly when it’s dinner time.
Also, if you’re watching your sodium intake, you’ll be happy to know that the extra sodium in softened water is negligible. It’s way less than what’s in a slice of bread. So don’t panic.
