The valves and membranes of your breast pump help with the suction and the flow of milk into the collection bottle when pumping, so keeping them in good shape or replacing when necessary is key. Depending on how frequently you pump, consider replacing every 4 to 12 weeks.
Note: Colors may vary but function is the same for all color types.
