The Reverse Osmosis Systems Four Way Valve is ideal for controlling the flow of water coming from a water filter where you want the water to be turned off when the tank is full.
This accessory is absolutely necessary in all reverse osmosis systems. It has an internal "drum" which inflates as soon as 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 run non-stop, constantly throwing water down the drain. If you notice that the reverse osmosis system in stock continues to work while your tank is full, then this part is the first one that needs replacing.
