I have well water and hard water. I replaced my old softner with a new Water-Right system almost a year ago. I never had a problem with white (salt?) buildup in my hot water tank before. I now have buildup above the water heater drain cock and cannot drain the tank of water or buildup. I am concerned that the buildup will eventually cover the bottom electric water heater element. The setting on the softner is 9 and the actual hardness is 11. Any idea about what is happening?
