304 Stainless Steel Water Level Control Valve Automatic Kitchen Faucet Water Full Stop Water Tower Water Tank Reservoir Float Valve Product Matching Tape Fully Automatic Water Level Control Float Valve

【No Electricity Required】The water valve inside allows water to flow until it reaches a certain water level. Once the water level reaches this height, the float valve will be pushed up by the water due to buoyancy and stop the water flow. When the water level starts to drop, the valve will open again and the water will start flowing again, so no electricity is required
