1. Water filling treatment Before selecting the power-on power, make sure that the fire pump should be filled with water when it is turned off, and the suction should be increased to make the pressure difference larger and quickly clean up some acid-base reagents and other pollutants. Make sure to fill the water well.

2. Selection of electrified power The horsepower of the fire pump will be selected according to the size of the pump. Before electrifying the pump, carefully check the electrical power. Once the power is not grasped accurately, it is easy to cause insufficient suction. Therefore, in order to make it have sufficient suction, the power should be selected reasonably. If there is no electricity, the fire pump cannot be started, let alone used. But does it mean that the pump can be used as long as there is electricity? Not necessarily, the pump can only be used if the electrified power is reasonable and the voltage is within the normal range.

Troubleshooting common issues with fire pumps involves systematic checks of components, electrical systems, and fluid dynamics. Regular maintenance and having a qualified technician perform diagnostic tests are essential.
