New one of these with extra solenoid included.
The Tunze RO Water Controller 8555 is used to regulate the water level in your fresh water storage container. It uses two float switches to control an electronic valve. When the water level drops below the first float switch, the valve is opened allowing the container to fill until it reaches the second float switch and the valve turns off. The Tunze RO Water Controller 8555 also features a timer backup that can be set to either 12 or 24 hours. If the float switch hasn't been triggered off within the set time the valve will close and an alarm will be activated. Retails for $220 or so, close to twice that considering the extra solenoid.
