I have been having trouble with the valves tearing which affects the suction. I just started pumping once a day last weekend and have had 4 tear. I am going to call customer service today to see if they can tellme why this keeps hhappening and how to prevent it.
You need to replace the valves about once a month. Ameda customer service is really good though, I would give them a call and see if they can troubleshoot anything else for you.
