Replace the impeller to ensure reliable performance. The installation of a new rotor can greatly reduce the noise generated by the wear of the rotor due to a long time, as well as the fluctuation of water flow. This rotor is not suitable for use in strongly acidic and alkaline media. Pay attention to regular cleaning and maintenance to ensure the normal operation of the rotor. Please cut off the power before replacing the rotor. The rotor is consumable and is not warranted. When your outer cylinder barrel produces water flow reduction, noise, and water flow fluctuation, it may be caused by rotor wear, just replace the rotor.
