1. If the water pump has any small fault, remember not to let it work. If the packing of the water pump shaft is worn, it should be added in time. If the water pump continues to be used, it will leak. The direct impact of this is that the motor energy consumption increases, which will damage the impeller.

2. If a strong vibration occurs during the use of the water pump, you must stop and check the cause, otherwise the water pump will be damaged.

3. When the bottom valve of the water pump leaks, some people will fill the inlet pipe of the water pump with dry soil and flush it with water, which is really not advisable. Because when the dry soil is put into the water inlet pipe, when the pump starts to work, the dry soil will enter the pump, which will damage the pump impeller and bearing, thus shortening the service life of the pump. When the bottom valve leaks, it must be repaired. If it is serious, it needs to be replaced.

4. The water pump must be maintained after use. For example, when the water pump is used up, the water in the water pump should be drained. It is better to remove the water pipe and wash it with clean water.

5. The tape on the water pump should also be removed, washed with water and dried in the light. Do not put the tape in a dark and damp place. The adhesive tape of the water pump must not be stained with oil, let alone coated with something sticky.

6. Carefully check whether there are cracks on the impeller and whether the impeller is loose on the bearing. If there are cracks and looseness, repair them in time. If there is mud on the pump impeller, clean it up.
