Under normal operating conditions, a standard cabinet-style water softener brine tank should maintain a water depth of about 6 to 12 inches at the bottom beneath the dry salt stack. The water level depends on your system's specific model, but it should never fill all the way to the top of the salt. A properly functioning brine tank uses this standing water to dissolve sodium or potassium pellets, creating a concentrated brine solution required for the automatic resin bed regeneration cycle. If the tank is completely dry or overflowing with water, a mechanical valve or float malfunction is present. Verification: Inspect the brine well inside your tank to confirm water sits at a moderate depth below the solid salt layer.
