Abstract
A water filtering system including an inlet, an outlet and a filter positioned between the inlet and the outlet, where feed water enters the inlet and passes through the filter, and filtered water exits the through the outlet. A measurement device is connected to at least one of the inlet and the outlet measures a concentration of Total Dissolved Solids in at least one of the inlet and the outlet. A bypass valve is connected between the inlet and the outlet, and moves between a closed position and an open position, where the filtered water moves from the outlet to the inlet. A controller communicates with the measurement device and the bypass valve and automatically moves the bypass valve to a position between the closed position and the open position based on the concentration of the Total Dissolved Solids in the filtered water measured by the measurement device.
