For a typical household, a 40-pound bag of water softener salt will usually last about six to eight weeks. That’s roughly the lifespan of a houseplant you’re trying not to kill.
But here’s the kicker: your mileage will vary. A family of four with teenagers who take epic showers will burn through salt faster than a quiet couple who both work from home.
Think of it like gas in your car. One person gets 300 miles out of a tank; another gets 200 because they drive like they’re in a heist film. Your water softener is the same.
