How often should the valve + diaphragms be changed?

Just like the valve , the diaphragms in the back-flow protectors can stretch and degrade over time, impacting suction. We recommend to replace these every 2 to 3 months if you pump once a day, and replace every 6 to 8 weeks if you pump more frequently.
