Description
RO/DI Flood Guardian
Automatic shut-off protection for RO/DI water reservoir filling.
Automatically filling a reservoir has never been easier or safer! No more standing by your water reservoir while water is being made, or setting a timer to catch it before it overfills. Forgetting to shut off your RO/DI system and flooding your rooms is a thing of the past!
The RO/DI Flood Guardian automatically and safely shut off your RO or RO/DI system the moment the set water level is reached. Start filling with just one press and let the RO/DI Flood Guardian handle the rest.
One-Press Filling with Automatic Stop
Start filling with a single button press, or by plugging in your Flood Guardian.
When the water reaches the sensor, the electronic valve immediately shuts off the RO/DI water supply.
There’s no timer to set and no adjustments required — simply begin filling and let the system handle the rest.
Ideal for Saltwater Mixing Station, ATO Reservoirs, Water Jugs and More
Perfect for saltwater mixing containers and RO/DI storage reservoirs.
Water can be prepared while performing other tasks or tank maintenance, without monitoring the container. The system automatically stops when the water reaches the sensor level.
Dual Optical Water-Level Sensors
Dual optical sensors electronically detect water level instead of using traditional mechanical floats.
The sensors directly detect the water level and control the electronic shut-off valve with precision.
The secondary sensor provides a built-in safety backup to prevent overfilling.
Reliable and Easy Upgrade over Float Valves
Guided by dual optical sensors, the valve responds instantly and shuts off with precision — delivering consistent, dependable control every time you fill.
Can be easily installed in a few minutes. No supervision required.
Just automatic, accurate water management.
Magnetic Sensor Mounting
The sensor mounts securely using magnets.
Positioning takes only seconds and works on most common reservoir walls. No drilling or permanent installation is required, and the sensor can easily be repositioned when needed.
Plug-and-Play Installation
Everything needed for installation is included.
Simply mount the sensor, connect the RO tubing to the solenoid valve, and power on the controller.
No plumbing modification, programming, or additional parts are required.
Clear Status Indication
The controller includes LED status indicators and an audible notification when filling is complete.
You can quickly confirm the operating status at a glance, and the alert lets you know when the reservoir has finished filling.
A Superior Alternative to Float Valves
Mechanical float valves are difficult to install. Along with more complicated plumbing, drilling a hole in your reservoir is often required. Additionally, float valves tend of clog and the mechanism tends to leak or get stuck over time.
The Flood Guardian is super easy to installs and extremely reliable. The sensor and filling bracket can moved from one reservoir to another in seconds. Ours normally-closed solenoid is also extremely reliable and is designed to fail in the closed/off position to further prevent floods.
Instead of monitoring a filling container or remembering to turn off the water, the system manages the process automatically and stops at the correct level.
Start filling, continue your work, and return when the water is ready.
