Made of good material, sturdy, solid, , practical and serve you for a long time. The sensing chamber and the electronic component chamber are separated in design to avoid the adsorption of iron-containing substances in the pipeline by some special material, so as to avoid the switch failure. High temperature resistance that it is produced by high temperature resistant materials, so that the products can be used under both hot and cold water conditions. The maximum temperature can reach 70°. Low water pressure start. The reset spring king adopts good quality stainless steel material, which can start when the water flow pressure reaches >0.03KG, and achieve the function of low water pressure to open the water pump. Electronic components are used as control devices to make the products spark-free and fully enclosed during operation, safe to use., Manufacturer: ZXZZAS
