The minerals in hard water prevent soaps and detergents from reaching a high foamy state when cleaning laundry causing you to add more detergent. Water hardness can also cause lime build up in water lines, washing machines, refrigerator lines, and water heaters. Using a water softener can prevent costly repairs in the future.
50 pound block salt used in water softener systems dissolves in water and doesn't turn into a past. Block salt breaks down slower than pellet salts and lasts longer in water softening systems.
