Overflow prevention and auto shutoff: The tank automatically stops filling when full, preventing spills and potential damage. Automatic water level sensing and conservation: Continuously monitors level to prevent overflow and reduce water waste. Compatibility with standard float valves: Works with shutoff, mini and automatic float valves and common tank fittings for easy retrofits. Durable, compact construction: Corrosion resistant design that fits in small spaces and is suitable for residential or light commercial tanks, ponds, and storage vessels. Use scenarios: Rainwater harvesting barrel connected to an irrigation line to stop fill when the barrel is full, avoiding overflow. Garden pond or decorative water feature to manage inflows and prevent spills during heavy rainfall. Livestock trough or utility storage tank to maintain safe levels and minimize water loss.
