Aquatic Life Barrel Buddie Smart Water Level Sensor
The Barrel Buddie monitors water levels at both high and low points in your barrel or container. When the lower sensor detects the water level, the low voltage solenoid opens and allows water to flow into the container. When the water level reaches the upper sensor, the solenoid closes.
Unlike float valves or auto top-off systems, the Barrel Buddie reduces TDS creep by allowing the reverse osmosis (RO) unit to operate only once to refill the container. This helps maintain better TDS levels in your collection container and can extend the life of your deionized (DI) filtration resin if used.
How It Works
- Upper sensor detects the maximum water level and closes the solenoid.
- Lower sensor detects the minimum water level and opens the solenoid to refill the container.
- The system ensures water is added only when needed, minimizing unnecessary operation of the RO unit.

FAQ
How does the Barrel Buddie prevent TDS creep?
The Barrel Buddie reduces TDS creep by triggering the RO unit only once per refill cycle. This ensures the RO system operates only when necessary, minimizing continuous operation and maintaining stable TDS levels in the container.
Can the Barrel Buddie be used with DI filtration systems?
Yes, the Barrel Buddie is compatible with DI filtration systems. By reducing the frequency of RO unit operation, it helps preserve the DI resin and maintains better water quality over time.
What happens if the water level is too high or too low?
The system uses upper and lower sensors to detect water levels. If the water level exceeds the upper sensor, the solenoid closes. If it drops below the lower sensor, the solenoid opens to refill. The system operates within the set range and does not exceed safe limits.




Theresa Taylor –
I’ve been using the Barrel Buddie with my RO system for three months now. It’s been very reliable. The water level is maintained consistently, and I notice my TDS readings are more stable. The system only activates when needed, which saves energy and reduces wear on my RO unit.
Sophie Mitchell –
The installation was simple and the sensors work well. I set the low level and it automatically refills when the water drops. I didn’t have to manually top off the barrel, which was a big relief. The only minor issue is that it takes a few minutes to fully refill, but it’s still better than using a float valve.

After switching from a float valve to the Barrel Buddie, my DI resin has lasted longer. The system prevents constant operation of the RO unit, which I believe is helping preserve the resin. It’s quiet, reliable, and easy to maintain.
