Is the fountain water pump buzzing? Don't rush to smash! 3 steps to find the real culprit!

First, get close and listen - if there is a buzzing sound with vibration, it is likely that the leaves are stuck with stones or leaves;

If there is a metallic sound of 'quack', it must be due to bearing wear!

Many people turn off the power and disassemble the pump as soon as they hear the sound, but in fact, they can make a preliminary judgment by recording a segment of sound with their mobile phone and comparing it with the sound.

Save the trouble of dismantling for half a day, as the parts get worse with each repair!

Remember: abnormal noise is a distress signal from the water pump! Targeted treatment is more effective than blind repair!
