【Automatic Function】When the water level is below the valve level, the float will automatically replenish water for your water tank, water tower, livestock water trough, fountain, or animal watering trough. Once the water level reaches the valve, the replenishment will automatically stop and close when the water level reaches the internal float. This ensures your water tank is always full. 【Easy Installation】This is an automatic water level control valve. The float is small, making installation easy. The external thread is 1/2 inch. 【No Power Required】The built-in float valve allows water to flow until the set water level is reached. Once the set water level is reached, the float valve moves upward under buoyancy, stopping the water flow. When the water level drops, the valve reopens, and the water flow resumes. Therefore, no electricity is required. 【Wide Range of Applications】It can be used to maintain the water level in garden waterfalls, garden fountains, rain gutters, etc., and can be used with automatic pool float valves for automatic shut-off in swimming pools, chicken coops, automatic chicken watering troughs, livestock watering troughs, outdoor rain buckets, fountain injectors, etc. 【Safety】The valve body is made of stainless steel, making it environmentally friendly and safe. 【Caution】If using an automatic float valve indoors, be sure to equip it with an emergency overflow system. Automatic float valves may malfunction, leading to flooding. It is recommended to always set the water flow rate to the minimum required to maintain the water level.
