1. If there is any minor fault with the water pump, remember not to let it work. If the packing of the water pump shaft is completely worn out, it must be added in time. If the water pump continues to be used, air leakage will occur. The direct impact of this is that the energy consumption of the motor will increase and the impeller will be damaged.

2. If the water pump vibrates strongly during use, you must stop and check the cause, otherwise it will also cause damage to the water pump.

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 the bottom valve with water. This approach is really not advisable. Because when dry soil is put into the water inlet pipe when the water pump starts to work, the dry soil will enter the pump, which will damage the water pump impeller and bearings, which shortens the service life of the water pump. When the bottom valve leaks, it must be repaired. If it is serious, it needs to be replaced with a new one.

4. Pay attention to maintenance after using the water pump. For example, when the water pump is used up, the water in the water pump should be drained. It is best to remove the water pipe and then rinse it with clean water.

5. Remove the tape from the water pump, rinse it with water and dry it in the light. Do not place the tape in a dark and humid place. The tape of the water pump must not be stained with oil, let alone apply sticky things on the tape.

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 dirt on the water pump impeller, clean it up.

7. The interface between the water pump and the pipe must be sealed, because if any debris enters, it will cause damage to the inside of the water pump.

8. The bearings on the water pump are also the focus of inspection. After use, check whether the bearings are worn. If the water pump is used for a long time, the small balls in the bearings will break, so it is best to apply a layer of paint on the bearings after the water pump is used. Lubricating oil better protects water pump bearings.
