The Auto Top Up Valve is a simple and reliable mechanical float valve designed to automatically maintain a consistent water level in aquariums, paludariums, and sump systems. When the water level drops due to evaporation, the float valve automatically allows water to refill the tank, and shuts off the water supply once the desired level is reached, preventing overflow and reducing daily maintenance.
Made from durable acrylic and plastic materials, the valve is easy to install using a standard hose connection and is suitable for both freshwater and marine aquariums, making it an efficient, low-cost solution for stable water level management.
