Routine Maintenance: It is recommended to clean the pump at least every two weeks to prolong its lifespan; otherwise, hair buildup can affect its operation. Easy Cleaning: Disassemble the pump and remove the cap and impeller. Remove all debris from the impeller and thoroughly clean it with a cotton swab. Quiet Design: Low noise level is less than 30 dB. If the pump is too noisy, please check if the fountain's water volume is too low or if the pump is blocked. Benefits of Use: The water circulating through the pump helps keep the water pure and limit contamination, increases oxygen levels, and prevents bacterial growth and dirt buildup.
