The brine line connects the softener to your salt tank. It’s usually a thin, flexible tube that comes with the unit. Just push it into the designated fittings on both ends. No tools, no swearing. If your softener is a combo unit (all-in-one), you might skip this step. Lucky you.
Now, pour a bag of water softener salt into the brine tank. Not table salt—unless you want to pay $4 for a teaspoon of seasoning. Use pellets or crystals, and fill it about halfway. Your softener will eat this like a toddler eats crayons: slowly and messily.
