Auto Shut-Off Float Valve Upgrade Kit

Auto shut off valves will allow your RO system to automatically turn on and off based on the activation of a float valve and are ideal for an auto top-off solution. Auto shut off valves do require a minimum of 40 PSI to operate correctly and can be installed on any style of reverse osmosis system that uses 1/4″ tubing.

The Auto Shut-Off Float Valve Upgrade Kit comes with everything you need to allow your RO/DI system to be used be to automatically top off your aquarium or RO reservoir. By utilising a 1/4″ RO Automatic Shut-Off Valve, back pressure created by the float valve shuts off the water supply to the RO membrane, preventing wastewater from continuing to run after the float valve is activated.

  • To operate correctly, the 1/4″ RO Automatic Shut-Off Valve requires a minimum feed-in water pressure of 40 PSI.
  • This upgrade kit is NOT compatible with Boosted RO/DI Systems.
