I have about a 5 year old Aqualink system that includes the Aquapure 1400. In the last three years I have replaced one board, two sensors and the cell.(Converted to 3-port cell) I always bring the cell in the house for the winter but not the cell because the wiring is in conduant. Considering the cost of these parts does anyone think there would be any benefit to bringing the sensor and the boards on the house for the winter ?
