Hi, there! Thank you for asking about the Mars 21782 condensate pump. To maintain your condensate pump, you must always clean it using a bottlebrush or similar tool to clean all openings where the drain lines connect. Next, remove or unclog any blockages that may have developed over time, and rinse the pump with water. To avoid unnecessary damage, do not saturate the pump motor with water.
