Backflow protectors and diaphragms are essential parts of closed system breast pumps. They act as a barrier to prevent breast milk (and moisture) from entering the tubing and pump motor, which can lead to contamination. Depending on how frequently you pump, consider replacing these parts every 6 to 24 weeks.
