Macerator pumps need to be cleaned on a regular basis to maintain them. It’s best to clean a macerator pump once a month in areas with hard water and once every three months in areas with soft water. You can use a brand-specific cleaner and descaler to clean it out or use home remedies like a white vinegar and water solution. It is important to note that you must disconnect the pump before proceeding with the cleaning. Allow it to dry out for at least two hours before reconnecting the power supply and flush with clean water.
