1. The water machine body is designed with engineering plastics, and the liquid receiving part is made of non-rusting material.2. Adopt plastic raw materials of edible containers imported from Europe and America to ensure the water quality is safe and healthy.3. Use the pressure switch. When the water pressure is insufficient, the pump will start to pressurize by itself, and when the water pressure is sufficient, it will stop automatically.4. The motor is equipped with temperature overload protection device to prevent the motor from burning.5. Built-in reverse check valve.6. The water temperature control switch can be selected to prevent the mechanism damage caused by the idling of the pressurizer when the water source is insufficient or the outlet is closed.
