It is crucial to never turn on the pump without filling it with water beforehand, as this could cause harm to the mechanical seals and impellers, Therefore, please check if the pump is filled with water before switching it on, To do this, inspect the drain plug of the pump to ensure it is inserted properly, If it is, add more water to the pump. Any excess water will seep into the pipeline and help generate suction.
