Prevent aquarium floods by adding the super-easy-to-install Flood Protector to your RO or RO/DI System. Never worry about forgetting to turn off your RO/DI system or overfilling your reservoir again! Simply mount the magnetically-mounted sensor to any reservoir/bucket/jug and the water will stop once the reservoir is filled. No drilling is required and there is no unreliable float valve to fail. Our proprietary dual-optical sensor provides unparallel security. Additionally, there is no frustrating pressure solenoid to install: the electronic solenoid kit installs in seconds. Optionally, use the RO/DI Flood Protector with a 7-day timer to automatically refill your ATO reservoir. Simply program the timer to turn on once every 1-7 days and the system will refill your reservoir based on your timer settings. No more TDS Creep!
