Water softener service.. Tested water hardness, found to be at approximately 17 grains of hardness. Possibly something changed in the well contributing to change in water quality. Tested softener operation, adjusted regeneration for every three days instead of four. Res-up tank was empty, provided gallon of res-up and filled tank. Started regeneration. Instructed customer to give it a couple of days and if they don’t notice any change to give us a call to test the water again.
