Water in the brine tank is completely normal for our systems and will always be present until the next regeneration removes it on the brine draw phase.
The water level in the brine tank is going to fluctuate with the current salt level.
Ex. 80lbs of salt is about ½ of a brine tank full. With this amount of salt in the tank, the water level should also be close to about ½” a tank full.
*Water slightly above or below the salt level is normal and not an issue.
