Four-way valve for reverse osmosis systems is ideal for controlling the flow of water coming from a filter. It stops the water supply when the tank is full. Suitable for use with a 1/4" (6.35 mm) reverse osmosis water tube. This component is absolutely essential in all reverse osmosis systems.

It features an internal "drum" that expands once the reverse osmosis water tank is full. Essentially, this component gives the command to stop the reverse osmosis from working once the water tank is completely full. Without this component, the reverse osmosis would continue to work non-stop, constantly wasting water down the drain.

If you notice that the reverse osmosis system continues to work while your tank is full, then this component is the first one that needs replacement.
