I don't think it's a problem.</p> <p>: @aprk: you def have to close the other tube or it barely works! </p> https://boards.hellobee.com/topic/medela-pisa-making-knocking-noises#post-749143 Sun, 28 Apr 2013 16:02:46 +0000 aprk 749143@https://boards.hellobee.com/ <p>Mine seemed super lame when I pumped yesterday, too. I was only using one side though, so I think I should have closed the second tube. </p> https://boards.hellobee.com/topic/medela-pisa-making-knocking-noises#post-749129 Sun, 28 Apr 2013 15:25:45 +0000 lomom 749129@https://boards.hellobee.com/ <p>My pump is 9-10 days old and started making knocking noises today, like the actual pump portion. It seems like there's little to no suction. I keep adjusting the knob and I get some suction but not a ton. I've only managed to pump maybe 30cc, I usually get more like 55-65 in a session. </p> <p>I'm freaking out! I just JUST bought this pump! </p>
