In most cases, the leakage of the float valve interface is caused by poor sealing of the threaded connection. It can be solved by properly winding the raw tape, using appropriate gaskets or sealants, and tightening them in accordance with regulations. Wind raw tape clockwise against thread tightening direction, Apply 15-25 turns cover 2-3mm thread thickness, For large threadsgaps, add extra turns.If the water outlet continues to leak, please mix silicone Teflon tape and regular Teflon tape... Smart Auto-Shutoff - Uses water pressure 0.02-1.2MPa to control flow withoutelectricity.A float valve inside allows water to flow until a specific level is reached. Once the water reaches this level, the float valve will be pushed up by the water due to buoyancy and stop the flow. When the water level starts to drop, the valve will open again, and the water will resume flowing.. Multi-Interface Kit - We provide 12'', 34'' straight and elbow male to meet the needs of different scenarios. Easy to use whether your water tank is top entry or side entry.. Safe Durable Material - Made of 304 stainless steel, this float valve is corrosion-resistant and non-toxic, ensuring safety for drinking water applications. It offers strong resistance to friction and impact, effectively prolonging the product's service life.Operating temperature range 0C100C32F212F.The stainless steel construction effectively eliminates the risk of cracking commonly seen in traditional plastic valveseven in extreme weather, the product itself remains durable and reliable.Note In freezing conditions, please ensure the water does not freeze, as the valve will not function when ice forms..
