AutoAqua RODI Flood Guardian

AutoAqua RODI Flood Guardian Provides Automatic Overflow Protection

The AutoAqua RODI Flood Guardian automatically shuts off RO/DI water production when a reservoir reaches the desired water level, helping aquarium owners prevent overflows before they happen. Making RO/DI water is a routine part of aquarium maintenance, but it only takes one distraction to create a mess. This system monitors water levels and closes the included solenoid valve when the container is full, helping protect floors, cabinets, and equipment from accidental water damage.

Created by AutoAqua, the Flood Guardian installs without drilling holes or permanently modifying a container. The magnetic sensor mounts in seconds and can easily move between reservoirs, mixing stations, and ATO containers whenever your setup changes.

Why the AutoAqua RODI Flood Guardian Belongs on an Aquarium System

Many hobbyists spend time maintaining stable water quality, yet the water production side of the hobby often receives less attention. An overflowing RO/DI reservoir can damage surrounding equipment and create unnecessary cleanup. The AutoAqua RODI Flood Guardian helps eliminate that concern by automatically stopping water flow when the water level reaches the sensor.

Whether you are producing freshwater for water changes, maintaining an ATO reservoir, or storing purified water for future use, this system allows you to walk away from the filling process with greater confidence. Instead of constantly checking water levels, you can focus on other maintenance tasks while the Flood Guardian monitors the container for you.

Simple Installation for RO/DI Reservoirs and Storage Containers

The AutoAqua RODI Flood Guardian works with standard 1/4-inch RO tubing and installs on most RO/DI systems in just a few minutes. The optical sensor attaches magnetically to containers with walls up to 1/2 inch thick, allowing installation without tools, drilling, or permanent mounting hardware.

Many hobbyists rely on dependable aquarium filters to maintain clean water inside the aquarium. Likewise, the Flood Guardian helps protect the water preparation side of the hobby by preventing accidental overfills before they become a problem. Because the sensor can be repositioned quickly, it works well for hobbyists who use multiple containers for water storage and mixing.

Dual Optical Sensors Increase Reliability

Unlike many water-level devices that use a single sensor, the AutoAqua RODI Flood Guardian uses dual optical sensors positioned vertically. This design provides an additional layer of protection by verifying the water level before activating the shut-off process. As a result, the system offers dependable operation during everyday use.

The sensor functions in both bright and dark environments and continues monitoring regardless of room lighting conditions. Combined with the magnetic mounting system, this allows the Flood Guardian to provide reliable protection without adding complexity to your setup.

Added Protection During Power Outages

The included solenoid valve features a normally closed design, which means it automatically closes when power is interrupted. This built-in safeguard helps prevent unwanted water flow if an outage occurs while producing RO/DI water.

For aquarium owners who regularly fill reservoirs overnight or while away from home, this additional protection provides valuable peace of mind. Rather than relying on memory or timers, the Flood Guardian actively monitors the water level and responds automatically when needed.

Frequently Asked Questions About the AutoAqua RODI Flood Guardian

Does the AutoAqua RODI Flood Guardian replace a float valve?

In many aquarium setups, yes. The optical sensors monitor water levels and automatically stop water flow without relying on a traditional mechanical float valve.

Can the AutoAqua RODI Flood Guardian be moved between containers?

Yes. The magnetic mounting system allows the sensor to be installed, removed, and repositioned in seconds without drilling holes or making permanent modifications.

Will the AutoAqua RODI Flood Guardian work during a power outage?

Yes. The included solenoid valve defaults to a closed position when power is lost, helping prevent water from continuing to flow.

What tubing size does the AutoAqua RODI Flood Guardian support?

The system is designed to work with standard 1/4-inch RO tubing commonly used on aquarium RO/DI systems.

Can the AutoAqua RODI Flood Guardian be used with ATO reservoirs and mixing stations?

Absolutely. The Flood Guardian works well with ATO reservoirs, freshwater storage containers, saltwater mixing stations, and other aquarium water storage applications where overflow protection is needed.
