Our auto shut-off valves used with reverse osmosis water systems are effortless and effective. When the unit reaches a full tank, these valves automatically turn off the water production, monitor the pressure inside the tank, and sense when the tank is full. The auto shut-off valve turns off the water into the reverse osmosis membrane.
The auto shut-off valve uses back pressure created by the float valve. That pressure is used to shut off water production. If your reverse osmosis system has this feature, it's a great option because it automatically works and doesn't rely on electricity as it's pressure-based.
