Say goodbye to accidental overflows and water damage with the Flood Guardian, the world’s first and only electronic float valve kit for RO and RO/DI systems. Designed for effortless installation and maximum protection, the Flood Guardian automatically shuts off your water supply when your container is full—no drilling, no float valves, and no complicated plumbing required.
Simply attach the magnetically-mounted dual-optical sensor to the side of any reservoir, bucket, jug, or container (up to ½" thick), and you're done. Once the water reaches the sensor, the electronic solenoid immediately stops the flow. It’s that simple—and that effective.

✅ Magnetic Sensor Mount – Easily attach to any container up to ½" thick
