I always see it recommended to replace the valves on the PISA pumps every few months or when suction decreases. What about the Freestyle? I went to buy new valves & it looks like it's only possible to replace the entire valve assembly at $25 a pop, which made me wonder if it's necessary to do. Anyone with a Freestyle who can tell me what they do with pump maintenance? TIA!
