ABSTRACT:
A control mechanism for a liquid treatment system including a first tank having an inlet and an outlet and a second tank having an inlet and an outlet. The control mechanism includes an inlet passage for receiving liquid to be treated and an outlet passage for dispensing treated liquid. A first valve is provided having a first chamber in fluid communication with the inlet passage and a second chamber in fluid communication with the outlet passage. The first valve is rotatable between a first position and a second position. A second valve is provided in fluid communication with the second chamber of the first valve. The second valve is adapted to selectively open and close a fluid path between the second chamber of the first valve and the first tank and to selectively open and close a fluid path between the second chamber of the first valve and the second tank. When the first valve is located in the first position, the first chamber is in fluid communication with the inlet of the first tank and is sealed from the second tank and the second chamber of the first valve is in fluid communication with the outlet of the first tank. When the first valve is located in the second position, the first chamber is in fluid communication with the inlet of the second tank and the inlet of the second tank and is sealed from the first tank and the second chamber is in fluid communication with the outlet of the second tank.
