Features: This water level control float valve is made of 304 stainless steel, which has small size. It is easy to install and suitable for most threaded connections. When the water level is lower than the valve level, it will automatically fill your water tank with water. It automatically stops filling once it reaches the valve, so it closes when water reaches the internal float. When the water level reaches a certain height, the float valve will be pushed up by the water due to buoyancy and stop the water flow. When the water level drops, the valve opens again and the water starts flowing again, so no electricity is needed. Which is used at the water inlet to avoid sand and stones from clogging the float. This product is widely used for garden waterfall, garden fountain, swimming pool, and more.
