Original Pump 2 Valves & 2 Diaphragms

Pack of 2 valves and 2 diaphragms that work together to create the right suction for maximum comfort when expressing.

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 replacing these every 2 to 3 months if you pump once a day, and replace every 6 to 8 weeks if you pump more frequently.

Once opened this product may not be returned.
